                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, October 1, 2004), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

OBSOLETE PROVISIONS

    Provisions that become obsolete before the revision date stated on 
the cover of each volume are not carried. Code users may find the text 
of provisions in effect on a given date in the past by using the 
appropriate numerical list of sections affected. For the period before 
January 1, 2001, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, 1973-1985, or 1986-2000, published in 11 separate 
volumes. For the period beginning January 1, 2001, a ``List of CFR 
Sections Affected'' is published at the end of each CFR volume.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    Properly approved incorporations by reference in this volume are 
listed in the Finding Aids at the end of this volume.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed in 
the Finding Aids of this volume as an approved incorporation by 
reference, please contact the agency that issued the regulation 
containing that incorporation. If, after contacting the agency, you find 
the material is not available, please notify the Director of the Federal 
Register, National Archives and Records Administration, Washington DC 
20408, or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Statutory 
Authorities and Agency Rules (Table I). A list of CFR titles, chapters, 
and parts and an alphabetical list of agencies publishing in the CFR are 
also included in this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

[[Page 13]]

    Distress signal. The distress signal is a digital selective call 
using an internationally recognized distress call format in the bands 
used for terrestrial communication or an internationally recognized 
distress message format, in which case it is relayed through space 
stations, which indicates that a person, ship, aircraft, or other 
vehicle is threatened by grave and imminent danger and requests 
immediate assistance.
    (1) In radiotelephony, the international distress signal consists of 
the enunciation of the word ``Mayday'', pronounced as the French 
expression ``m'aider''. In case of distress, transmission of this 
particular signal is intended to ensure recognition of a radiotelephone 
distress call by stations of any nationality.
    (2) For GMDSS, distress alerts result in an audible alarm and visual 
indication that a ship or person is threatened by grave and imminent 
danger and requests immediate assistance. These automatic systems 
contain sufficient information in the distress alert message to identify 
the vessel, prepare to assist and begin a search. However, except when 
transmitted via satellite EPIRB, the distress alert is just the initial 
call for help. Communication between the vessel or person in distress 
and the Rescue Coordination Center (RCC) or ship assisting should always 
follow.
    Distress traffic. Distress traffic consists of all messages relating 
to the immediate assistance required by a person, ship, aircraft, or 
other vehicle in distress, including search and rescue communications 
and on-scene communications.
    Emergency position indicating radiobeacon (EPIRB) station. A station 
in the maritime mobile service the emissions of which are intended to 
facilitate search and rescue operations.
    Environmental communications. Broadcasts of information about the 
environmental conditions in which vessels operate, i.e., weather, sea 
conditions, time signals adequate for practical navigation, notices to 
mariners, and hazards to navigation.
    Fleet radio station license. An authorization issued by the 
Commission for two or more ships having a common owner or operator.
    Global maritime distress and safety system (GMDSS). An International 
Maritime Organization (IMO) worldwide coordinated maritime distress 
system designed to provide the rapid transfer of distress messages from 
vessels in distress to units best suited for giving or coordinating

Sec. 80.57  Canada/U.S.A. channeling arrangement for VHF maritime public 
correspondence.

    (a) Canada/U.S.A. arrangement. Pursuant to arrangements between the 
United States and Canada, assignment of VHF frequencies in the band 156-
162 MHz to public coast stations in certain areas of Washington state, 
the Great Lakes and the east coast of the United States must be made in 
accordance with the provisions of this section.
    (b) Definitions. On the west coast, specific terms are defined as 
follows:
    (1) Inland Waters Public Correspondence Sector. A distinct 
geographical area in which one primary and one supplementary channel is 
allotted. A number of local channels may also be authorized.
    (2) Coastal Waters Public Correspondence Sector. A distinct 
geographical area in which one primary and one supplementary channel is 
allotted. Local channels may also be authorized.
    (3) Inland Waters. Inland waters of western Washington and British 
Columbia bounded by 47 degrees latitude on the south, the Canada/U.S.A. 
Coordination Zone Line B on the north, and to the west by 124 degrees 40 
minutes longitude at the west entrance to the Strait of Juan de Fuca.
    (4) Coastal Waters. Waters along the Pacific Coast of Washington 
state and Vancouver Island within the Canada/U.S.A. Coordination Zone.
    (5) Inland Waters Primary Channel. A channel intended to cover the 
greater portion of an Inland Waters Public Correspondence Sector. It may 
provide some coverage to an adjacent sector but must not provide 
coverage beyond the adjacent sector. Harmful interference beyond the 
adjacent sector must not occur. Only one primary channel will be 
authorized in any sector.
    (6) Inland waters of western Washington and British Columbia bounded 
by 46[deg]59[min]59.3[sec] north latitude on the south, the Canada/
U.S.A. Coordination Zone Line B on the south, and to the west by 
124[deg]40[min]4.7[sec] west latitude at the west entrance to the Strait 
of Juan de Fuca.

    Note: All coordinates are referenced to North American Datum 1983 
(NAD83).

    (7) Inland Waters Local Channel. A channel designed to provide local 
coverage of certain bays, inlets and ports where coverage by primary or 
supplementary channels is poor or where heavy traffic loading warrants. 
A local channel must not cause harmful interference to any primary or 
supplementary channels. Coverage must be confined to the designated 
sector.
    (8) Coastal Waters Primary Channel. Same as (5) except for technical 
characteristics.
    (9) Coastal Waters Supplementary Channel. Same as (6) except for 
technical characteristics.
    (10) Coastal Waters Local Channel. Same as (7) except for technical 
characteristics.
    (c) Technical characteristics. On the west coast, technical 
characteristics of public correspondence stations will be as follows:
    (1) Inland Waters Primary and Supplementary Channels. The effective 
radiated power (ERP) must not exceed 60 watts. Antenna height must not 
exceed 152 meters (500 feet) above mean sea level (AMSL) with the 
exceptions noted in paragraph (d)(5) of this section.
    (2) Inland Waters Local Channel. ERP must not exceed 8 watts with an 
antenna height of no more than 15 meters (50 feet) AMSL or the ERP must 
not exceed 2 watts with an antenna height of no more than 30 meters (100 
feet) AMSL.
    (3) Coastal Waters Primary and Supplementary Channels. ERP must not 
exceed 125 watts with no antenna restrictions.

[[Page 22]]

    (4) Coastal Waters Local Channel. ERP must not exceed 10 watts with 
a maximum antenna height of 76 meters (250 feet) AMSL.
    (5) Harmful interference will be determined and resolved using the 
definition and procedures of the ITU Radio Regulations.
    (6) To keep the ERP and antenna elevations at a minimum and to limit 
coverage to the desired areas, an informal application may be filed for 
special temporary authority in accordance with Sec. Sec. 1.41 and 1.931 
of this chapter to conduct a field survey to obtain necessary data for 
informal application. Such data may accompany the application and be 
used in lieu of theoretical calculations as required in subpart P of 
this part. The Seattle FCC District Office must be notified in advance 
of scheduled tests.
    (d) Canada/U.S.A. channeling arrangement for West Coast VHF maritime 
mobile public correspondence. (1) The provisions of the Canada/U.S. 
channeling arrangement apply to waters of the State of Washington and of 
the Province of British Columbia within the coordination boundaries of 
``Arrangement A'' of the Canada/U.S.A. Frequency Coordination Agreement 
above 30 MHz. In addition, all inland waters as far south as Olympia are 
to be included. A map of these waters is contained in paragraph (d)(6) 
of this section, Figure 1.
    (2) The channeling arrangement applies to the following VHF public 
correspondence channels: Channels 24, 84, 25, 85, 26, 86, 27, 87 and 28.
    (3) Public correspondence stations may be established by either 
country in accordance with the provisions of the arrangements. However, 
there must be an exchange of information prior to the establishment of 
new stations or a change in technical parameters of existing stations. 
Any channel except that used as primary or supplementary channel in a 
given sector is available for use as a local channel in that sector. 
Local channels are not protected from interference caused by primary or 
supplementary channels in adjacent sectors if these stations are in 
compliance with this section.
    (4) Preliminary local Canadian/U.S. coordination is required for all 
applications at variance with this section. This coordination will be in 
accordance with the provisions of Arrangement ``A'' of the Canada/U.S. 
Frequency Coordination Agreement over 30 MHz. Stations at variance with 
the arrangement are not protected from interference and must not cause 
interference to existing or future stations which are in accordance with 
the agreement.
    (5) Stations in existence at the time of the arrangement must have 
complied with the provisions of the arrangement within 12 months after 
it became effective with the following exceptions:
    (i) Public coast (VHF) stations:

KOH627 Tacoma, Washington

    (2) A certification that the ship has passed an inspection must be 
entered into the ship's log by the inspecting technician. The technician 
conducting the inspection and providing the certification must not be 
the vessel's owner, operator, master, or employee or their affiliates. 
Additionally, the vessel owner, operator, or ship's master must certify 
in the station log that the inspection was satisfactory. There are no 
FCC prior notice requirements for any inspection pursuant to paragraph 
(a)(1) of this section. An inspection of

[[Page 25]]

the bridge-to-bridge radio stations on board vessels subject to the 
Vessel Bridge-to-Bridge Radiotelephone Act must be conducted by the same 
FCC-licensed technician.
    (3) Additionally, for passenger vessels operated on an international 
voyage the inspecting technician must send a completed FCC Form 806 to 
the Officer in Charge, Marine Safety Office, United States Coast Guard 
in the Marine Inspection Zone in which the ship is inspected.
    (4) In the event that a ship fails to pass an inspection the 
inspecting technician must make a log entry detailing the reason that 
the ship did not pass the inspection. Additionally, the technician must 
notify the vessel owner, operator, or ship's master that the vessel has 
failed the inspection.
    (5) Because such inspections are intended to ensure the availability 
of communications capability during a distress the Commission will 
vigorously investigate reports of fraudulent inspections, or violations 
of the Communications Act or the Commission's Rules related to ship 
inspections. FCC-licensed technicians, ship owners or operators should 
report such violations to the Commission through its National Call 
Center at 1-888-CALL FCC (1-888-225-5322).
    (b) Inspection and certification of a ship subject to the Great 
Lakes Agreement. The FCC will not inspect Great Lakes Agreement vessels. 
An inspection and certification of a ship subject to the Great Lakes 
Agreement must be made by a technician holding one of the following: an 
FCC General Radiotelephone Operator License, a GMDSS Radio Maintainer's 
License, a Second Class Radiotelegraph Operator's Certificate, or a 
First Class Radiotelegraph Operator's Certificate. The certification 
required by Sec. 80.953 must be entered into the ship's log. The 
technician conducting the inspection and providing the certification 
must not be the vessel's owner, operator, master, or an employee of any 
of them. Additionally, the vessel owner, operator, or ship's master must 
certify that the inspection was satisfactory. There are no FCC prior 
notice requirements for any inspection pursuant to Sec. 80.59(b).
    (c) Application for exemption. (1) Applications for exemption from 
the radio provisions of part II or III of title III of the 
Communications Act, the Safety Convention, or the Great Lakes Radio

Sec. 80.60  Partitioned licenses and disaggregated spectrum.

    (a) Eligibility. The following licensees may partition their service 
areas or disaggregate their spectrum. Parties seeking approval for 
partitioning and disaggregation shall request an authorization for 
partial assignment pursuant to Sec. 1.948 of this chapter.
    (1) VHF Public Coast area licensees, see Sec. 80.371(c)(1)(ii), may 
partition their geographic service area or disaggregate their spectrum 
pursuant to the procedures set forth in this section.
    (2) AMTS geographic area licensees, see Sec. 80.385(a)(3), may 
partition their geographic service area or disaggregate their spectrum 
pursuant to the procedures set forth in this section. Site-based AMTS 
public coast station licensees may partition their license or 
disaggregate their spectrum pursuant to the procedures set forth in this 
section, provided that the partitionee or disaggregatee's predicted 38 
dBu signal level contour does not extend beyond the partitioner or 
disaggregator's predicted 38 dBu signal level contour. The predicted 38 
dBu signal level contours shall be calculated using the F(50, 50) field 
strength chart for Channels 7-13 in Sec. 73.699 (Fig. 10) of this 
chapter, with a 9 dB correction for antenna height differential.
    (3) Nationwide or multi-region LF, MF, and HF public coast station 
licensees, see Sec. Sec. 80.357(b)(1), 80.361(a), 80.363(a)(2), 
80.371(b), and 80.374, may

[[Page 27]]

partition their spectrum pursuant to the procedures set forth in this 
section, except that frequencies or frequency pairs licensed to more 
than one licensee as of March 13, 2002 may be partitioned only by the 
earliest licensee, and only on the condition that the partitionee shall 
operate on a secondary, non-interference basis to stations licensed as 
of March 13, 2002 other than the earliest licensee. Coordination with 
government users is required for partitioning of spectrum the licensing 
of which is subject to coordination with government users.
    (b) Technical standards. (1) Partitioning. In the case of 
partitioning, all requests for authorization for partial assignment of a 
license must include, as an attachment, a description of the partitioned 
service area. The partitioned service area shall be defined by 
coordinate points at every 3 degrees along the partitioned service area 
unless an FCC-recognized service area is utilized (e.g., Metropolitan 
Service Area, Rural Service Area, or Economic Area) or county lines are 
used. The geographic coordinates must be specified in degrees, minutes, 
and seconds to the nearest second of latitude and longitude, and must be 
based upon the 1983 North American Datum (NAD83). In a case where an 
FCC-recognized service area or county lines are utilized, applicants 
need only list the specific area(s) (through use of FCC designations or 
county names) that constitute the partitioned area.
    (2) Disaggregation. VHF (156-162 MHz) spectrum may only be 
disaggregated according to frequency pairs. AMTS spectrum may be 
disaggregated in any amount.
    (3) Combined partitioning and disaggregation. The Commission will 
consider requests for partial assignment of licenses that propose 
combinations of partitioning and disaggregation.
    (c) License term. The license term for a partitioned license area 
and for disaggregated spectrum shall be the remainder of the original 
licensee's term as provided for in Sec. 80.25 of this part.
    (d) Construction Requirements. (1) Partitioning. Partial assignors 
and assignees for license partitioning have two options to meet 
construction requirements. Under the first option, the partitionor and 
partitionee would each certify that they will independently satisfy the 
substantial service requirement for their respective partitioned areas. 
If either licensee failed to meet its substantial service showing 
requirement, only the non-performing licensee's renewal application 
would be subject to dismissal. Under the second option, the partitioner 
certifies that it has met or will meet the substantial service 
requirement for the entire market. If the partitioner fails to meet the 
substantial service standard, however, only its renewal application 
would be subject to forfeiture at renewal.
    (2) Disaggregation. Partial assignors and assignees for license 
disaggregation have two options to meet construction requirements. Under 
the first option, the disaggregator and disaggregatee would certify that 
they each will share responsibility for meeting the substantial service 
requirement for the geographic service area. If parties choose this 
option and either party fails to do so, both licenses would be subject 
to forfeiture at renewal. The second option would allow the parties to 
agree that either the disaggregator or the disaggregatee would be 
responsible for meeting the substantial service requirement for the 
geographic service area. If parties choose this option, and the party 
responsible for meeting the construction requirement fails to do so, 
only the license of the nonperforming party would be subject to 
forfeiture at renewal.
    (3) Site-based AMTS, and nationwide or multi-region LF, MF, and HF 
public coast. Parties seeking to acquire a partitioned license or 
disaggregated spectrum from a site-based AMTS, or nationwide or multi-
region LF, MF, and HF public coast licensee will be required to 
construct and commence ``service to subscribers'' in all facilities 
acquired through such transactions within the original construction 
deadline for each facility as set forth in Sec. 80.49. Failure to meet 
the individual construction deadline will result in the automatic 
termination of the facility's authorization.

all four levels of priority, category 1 shall receive priority until 
such time as intergovernmental agreements remove exemptions granted for 
such systems from offering the complete order of priority.

[68 FR 46960, Aug. 7, 2003]



Sec. 80.92  Prevention of interference.

    (a) The station operator must determine that the frequency is not in 
use by monitoring the frequency before

[[Page 32]]

transmitting, except for transmission of signals of distress.
    (b) When a radio communication causes interference to a 
communication which is already in progress, the interfering station must 
cease transmitting at the request of either party to the existing 
communication. As between nondistress traffic seeking to commence use of 
a frequency, the priority is established under Sec. 80.91.
    (c) Except in cases of distress, communications between ship 
stations or between ship and aircraft stations must not interfere with 
public coast stations. The ship or aircraft stations which cause 
interference must stop transmitting or change frequency upon the first 
request of the affected coast station.

watch channels while ships are underway. If a ship has duplicate GMDSS 
installations for DSC or INMARSAT, only one of each must be turned on 
and keeping watch.
    (d) Ships voluntarily fitting GMDSS subsystems. For ships 
voluntarily fitting GMDSS subsystems, radios shall be turned on and set 
to proper watch channels while ships are underway. If ship has duplicate 
GMDSS installations for DSC or INMARSAT, only one of each must be turned 
on and keeping watch.
    (e) Other than public coast or compulsory ship stations. The hours 
of service of stations other than those described in paragraphs (b), 
(c), and (d) of this section are determined by the station licensee.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46960, Aug. 7, 2003]



Sec. 80.94  Control by coast or Government station.

    When communicating with a coast station or any Government station in 
the maritime mobile service, ship stations must comply with the 
instruction given by the coast station or Government station relative to 
the order and time of transmission, the choice of frequency, the 
suspension of communication and the permissible type of message traffic 
that may be transmitted. This provision does not apply in the event of 
distress.

with Article 66 of the Radio Regulations. Stations which elect not to 
recognize international AAIC's will be removed from the ITU List of 
Coast Stations.

[51 FR 31213, Sept. 2, 1986, as amended at 52 FR 35244, Sept. 18, 1987]



Sec. 80.96  Maintenance tests.

    Stations are authorized to engage in test transmissions necessary 
for maintenance of the station. Test transmissions must conform to 
appropriate test operating procedures.



Sec. 80.97  Radiotelegraph operating procedures.

    This section applies to ships and coast stations authorized to 
transmit in the band 405-525 kHz.
    (a) Except for the transmission of distress or urgency signals, all 
transmissions must cease within the band 485-515 kHz during each 500 kHz 
silence period.
    (b) Stations transmitting telegraphy must use the service 
abbreviations (``Q'' code) listed in Appendix 14 to the Radio 
Regulations.
    (c) The call consists of:
    (1) The call sign of the station called, not more than twice; the 
word ``DE'' and the call sign of the calling station, not more than 
twice; if useful, the frequency on which the called station should 
reply; and the letter ``K''.
    (2) If the call is transmitted twice at an interval of not less than 
one minute, it must not be repeated until after an interval of three 
minutes.
    (d) The reply to calls consists of: The call sign of the calling 
station, not more than twice; the word ``DE''; and the call sign of the 
station called, once only.



Sec. 80.98  Radiotelegraph testing procedures.

    (a) Stations authorized to use telegraphy may conduct tests on any 
assigned frequency. Emissions must not cause harmful interference. When 
radiation is necessary the radiotelegraph testing procedure described in 
this paragraph must be followed:
    (1) The operator must not interfere with transmissions in progress.
    (2) The operator must transmit ``IE'' (two dots, space, one dot) on 
the test frequency as a warning that test emissions are about to be 
made. When the frequency of the test emission is within the frequency 
band 405-525 kHz, a watch must be maintained on 500 kHz throughout the 
test period.
    (3) If any station transmits ``AS'' (wait), testing must be 
suspended. When transmission of ``IE'' is resumed and no response is 
heard, the test may proceed.
    (4) Test signals composed of a series of ``VVV'' having a duration 
of not more than ten seconds, followed by the call sign of the testing 
station will be transmitted. The call sign must be sent clearly at a 
speed of approximately 10 words per minute. This test transmission must 
not be repeated until a period of at least one minute has elapsed. On 
500 kHz in a region of heavy traffic, at least five minutes must elapse 
before the test transmission is repeated.
    (b) When testing is conducted on 500 kHz, no tests will be conducted 
during the 500 kHz silence periods. Care must be exercised not to so 
prolong and space the dash portion of the ``VVV'' series as to form the 
alarm signal.
    (c) When testing is conducted on any frequency in the band 8362-8366 
kHz, tests must not actuate any automatic alarm receiver.



Sec. 80.99  Radiotelegraph station identification.

    This section applies to coast, ship and survival craft stations 
authorized to transmit in the band 405-525 kHz.
    (a) The station transmitting radiotelegraph emissions must be 
identified by its call sign. The call sign must be transmitted with the 
telegraphy emission normally used by the station. The call sign must be 
transmitted at 20 minute intervals when transmission is sustained for 
more than 20 minutes. When a ship station is exchanging public 
correspondence communications, the identification may be deferred until 
completion of each communication with any other station.
    (b) The requirements of this section do not apply to survival craft 
stations when transmitting distress signals automatically or when 
operating on 121.500 MHz for radiobeacon purposes.

[[Page 34]]

    (c) Emergency position indicating radiobeacon stations do not 
require identification.



Sec. 80.100  Morse code requirement.

    The code employed for telegraphy must be the Morse code specified in 
the Telegraph Regulations annexed to the International Telecommunication 
Convention. Pertinent extracts from the Telegraph Regulations are 
contained in the ``Manual for Use by the Maritime Mobile and Maritime 
Mobile-Satellite Services'' published by the International 
Telecommunication Union.



Sec. 80.101  Radiotelephone testing procedures.

    This section is applicable to all stations using telephony except 
where otherwise specified.
    (a) Station licensees must not cause harmful interference. When 
radiation is necessary or unavoidable, the testing procedure described 
below must be followed:
    (1) The operator must not interfere with transmissions in progress.
    (2) The testing station's call sign, followed by the word ``test'', 
must be announced on the radio-channel being used for the test.
    (3) If any station responds ``wait'', the test must be suspended for 
a minimum of 30 seconds, then repeat the call sign followed by the word 
``test'' and listen again for a response. To continue the test, the 
operator must use counts or phrases which do not conflict with normal 
operating signals, and must end with the station's call sign. Test 
signals must not exceed ten seconds, and must not be repeated until at 
least one minute has elapsed. On the frequency 2182 kHz or 156.800 MHz, 
the time between tests must be a minimum of five minutes.
    (b) Testing of transmitters must be confined to single frequency 
channels on working frequencies. However, 2182 kHz and 156.800 MHz may 
be used to contact ship or coast stations as appropriate when signal 
reports are necessary. Short tests on 4125 kHz are permitted by vessels 
equipped with MF/HF radios to evaluate the compatibility of the 
equipment for distress and safety purposes. U.S. Coast Guard stations 
may be contacted on 2182 kHz or 156.800 MHz for test purposes only when 
tests are being conducted by Commission employees, when FCC-licensed 
technicians are conducting inspections on behalf of the Commission, when 
qualified technicians are installing or repairing radiotelephone 
equipment, or when qualified ship's personnel conduct an operational 
check requested by the U.S. Coast Guard. In these cases the test must be 
identified as ``FCC'' or ``technical.''
    (c) Survival craft transmitter tests must not be made within 
actuating range of automatic alarm receivers.

[51 FR 31213, Sept. 2, 1986, as amended at 63 FR 29659, June 1, 1998; 68 
FR 46961, Aug. 7, 2003]



Sec. 80.102  Radiotelephone station identification.

    This section applies to all stations using telephony which are 
subject to this part.
    (a) Except as provided in paragraphs (d) and (e) of this section, 
stations must give the call sign in English. Identification must be 
made:
    (1) At the beginning and end of each communication with any other 
station.
    (2) At 15 minute intervals when transmission is sustained for more 
than 15 minutes. When public correspondence is being exchanged with a 
ship or aircraft station, the identification may be deferred until the 
completion of the communications.
    (b) Private coast stations located at drawbridges and transmitting 
on the navigation frequency 156.650 MHz may identify by use of the name 
of the bridge in lieu of the call sign.
    (c) Ship stations transmitting on any authorized VHF bridge-to-
bridge channel may be identified by the name of the ship in lieu of the 
call sign.
    (d) Ship stations operating in a vessel traffic service system or on 
a waterway under the control of a U.S. Government agency or a foreign 
authoriy, when communicating with such an agency or authority may be 
identified by the name of the ship in lieu of the call sign, or as 
directed by the agency or foreign authority.
    (e) Voice traffic in the INMARSAT system is closed to other parties 
except the two stations involved and the identification is done 
automatically with

[[Page 35]]

the establishment of the call. Therefore, it is not necessary for these 
stations to identify themselves periodically during the communication. 
For terrestrial systems using DSC to establish radiotelephone 
communications, the identification is made at the beginning of the call. 
In these cases, both parties must identify themselves by ship name, call 
sign or MMSI at least once every 15 minutes during radiotelephone 
communications.
    (f) VHF public coast station may identify by means of the

Sec. 80.111  Radiotelephone operating procedures for coast stations.

    This section applies to all coast stations using telephony which are 
subject to this part.
    (a) Limitations on calling. (1) Except when transmitting a general 
call to all stations for announcing or preceding the transmission of 
distress, urgency, or safety messages, a coast station must call the 
particular station(s) with which it intends to communicate.
    (2) Coast stations must call ship stations by voice unless it is 
known that the particular ship station may be contacted by other means 
such as automatic actuation of a selective ringing or calling device.
    (3) Coast stations may be authorized emission for selective calling 
on each working frequency.
    (4) Calling a particular station must not continue for more than one 
minute in each instance. If the called station does not reply, that 
station must not again be called for two minutes. When a called station 
does not reply to a call sent three times at intervals of two minutes, 
the calling must cease for fifteen minutes. However, if harmful 
interference will not be caused to other communications in progress, the 
call may be repeated after three minutes.
    (5) A coast station must not attempt to communicate with a ship 
station that has specifically called another

[[Page 37]]

coast station until it becomes evident that the called station does not 
answer, or that communication between the ship station and the called 
station cannot be carried on because of unsatisfactory operating 
conditions.
    (6) Calls to establish communication must be initiated on an 
available common working frequency when such a frequency exists and it 
is known that the called ship maintains a simultaneous watch on the 
common working frequency and the appropriate calling frequency(ies).
    (b) Time limitation on calling frequency. Transmissions by coast 
stations on 2182 kHz or 156.800 MHz must be minimized and any one 
exchange of communications must not exceed one minute in duration.
    (c) Change to working frequency. After establishing communications 
with another station by call and reply on 2182 kHz or 156.800 MHz coast 
stations must change to an authorized working channel for the 
transmission of messages.
    (d) Use of busy signal. A coast station, when communicating with a 
ship station which transmits to the coast station on a radio channel 
which is a different channel from that used by the coast station for 
transmission, may transmit a ``busy'' signal whenever transmission from 
the ship station is being received. The characteristics of the ``busy'' 
signal are contained in Sec. 80.74.

156.800 MHz or on commercial or noncommercial VHF intership frequencies 
appropriate to the class of ship station with which it is associated.
    (2) Except for safety purposes, it must only be used to communicate 
with the ship station with which it is associated or with associated 
ship units of the same ship station. Such associated ship units may not 
be used from shore.
    (3) It must be equipped to transmit on the frequency 156.800 MHz and 
at least one appropriate intership frequency.
    (4) Calling must occur on the frequency 156.800 MHz unless calling 
and working on an intership frequency has been prearranged.
    (5) Power is limited to one watt.
    (6) The station must be identified by the call sign of the ship 
station with which it is associated and an appropriate unit designator.
    (b) State or local government vehicles used to tow vessels involved 
in search and rescue operations are authorized to operate on maritime 
mobile frequencies as associated ship units. Such operations must be in 
accordance with paragraph (a) of this section, except that the

frequency 156.800

[[Page 38]]

MHz for calling coast stations and marine utility stations on shore, and 
for replying to calls from such stations, is authorized. However, such 
calls and replies should be made on the appropriate ship-shore working 
frequency.
    (b) Calling ship stations. (1) Except when other operating procedure 
is used to expedite safety communication, ship stations, before 
transmitting on the intership working frequencies 2003, 2142, 2638, 
2738, or 2830 kHz, must first establish communications with other ship 
stations by call and reply on 2182 kHz. Calls may be initiated on an 
intership working frequency when it is known that the called vessel 
maintains a simultaneous watch on the working frequency and on 2182 kHz.
    (2) Except when other operating procedures are used to expedite 
safety communications, the frequency 156.800 MHz must be used for call 
and reply by ship stations and marine utility stations before 
establishing communication on one of the intership working frequencies. 
Calls may be initiated on an intership working frequency when it is 
known that the called vessel maintains a simultaneous watch on the 
working frequency and on 156.800 MHz.
    (c) Change to working frequency. After establishing communication 
with another station by call and reply on 2182 kHz or 156.800 MHz 
stations on board ship must change to an authorized working frequency 
for the transmission of messages.
    (d) Limitations on calling. Calling a particular station must not 
continue for more than 30 seconds in each instance. If the called 
station does not reply, the station must not again be called until after 
an interval of 2 minutes. When a called station called does not reply to 
a call sent three times at intervals of 2 minutes, the calling must 
cease and must not be renewed until after an interval of 15 minutes; 
however, if there is no reason to believe that harmful interference will 
be caused to other communications in progress, the call sent three times 
at intervals of 2 minutes may be repeated after a pause of not less than 
3 minutes. In event of an emergency involving safety, the provisions of 
this paragraph do not apply.
    (e) Limitations on working. Any one exchange of communications 
between any two ship stations on 2003, 2142, 2638, 2738, or 2830 kHz or 
between a ship station and a private coast station on 2738 or 2830 kHz 
must not exceed 3 minutes after the stations have established contact. 
Subsequent to such exchange of communications, the same two stations 
must not again use 2003, 2142, 2638, 2738, or 2830 kHz for communication 
with each other until 10 minutes have elapsed.
    (f) Transmission limitation on 2182 kHz and 156.800 MHz. To 
facilitate the reception of distress calls, all transmissions on 2182 
kHz and 156.800 MHz (channel 16) must be minimized and transmissions on 
156.800 MHz must not exceed 1 minute.
    (g) Limitations on commercial communication. On frequencies in the 
band 156-162 MHz, the exchange of commercial communication must be 
limited to the minimum practicable transmission time. In the conduct of 
ship-shore communication other than distress, stations on board ship 
must comply with instructions given by the private coast station or 
marine utility station on shore with which they are communicating.

Sec. 80.213  Modulation requirements.

    (a) Transmitters must meet the following modulation requirements:
    (1) When double sideband emission is used the peak modulation must 
be maintained between 75 and 100 percent;
    (2) When phase or frequency modulation is used in the 156-162 MHz 
band the peak modulation must be maintained between 75 and 100 percent. 
A frequency deviation of  5 kHz is defined as 100 
percent peak modulation; and
    (3) In single sideband operation the upper sideband must be 
transmitted. Single sideband transmitters must automatically limit the 
peak envelope power to their authorized operating power and meet the 
requirements in Sec. 80.207(c).
    (b) Radiotelephone transmitters using A3E, F3E and G3E emission must 
have a modulation limiter to prevent any modulation over 100 percent. 
This requirement does not apply to survival craft transmitters, to 
transmitters that do not require a license or to transmitters whose 
output power does not exceed 3 watts.
    (c) Coast station transmitters operated in the 72.0-73.0 MHz and 
75.4-76.0 MHz bands must be equipped with an audio low-pass filter. The 
filter must be installed between the modulation limiter and the 
modulated radio frequency stage. At frequencies between 3 kHz and 15 kHz 
it must have an attenuation greater than at 1 kHz by at least 
40log10 (f/3) dB where ``f'' is the frequency in kilohertz. 
At frequencies above 15 kHz the attenuation must be at least 28 dB 
greater than at 1 kHz.
    (d) Ship and coast station transmitters operating in the 156-162 MHz

159.480 MHz, 160.725 MHz, 160.785 MHz, 454.000 MHz and 459.000 MHz must 
employ a duty cycle with a maximum transmission period of 60 seconds 
followed by a minimum quiescent period four times the duration of the 
transmission period.
    (g) Radar stations operating in the bands above 2.4 GHz may use any 
type of modulation consistent with the bandwidth requirements in Sec. 
80.209(b).

9300-9500 MHz band must operate in a variable frequency mode and respond 
on their operating frequencies with a maximum error equivalent to 100 
meters. Additionally, their response must be encoded with a Morse 
character starting with a dash. The duration of a Morse dot is defined 
as equal to the width of a space and 1/3 of the width of a Morse dash. 
The duration of the response code must not exceed 50 microseconds. The 
sensitivity of the stations must be adjustable so that received signals 
below -10 dBm at the antenna will not activate the transponder. Antenna 
polarization must be horizontal when operating in the 9300-9500 MHz band 
and either horizontal or both horizontal and vertical when operating in 
the 2900-3100 MHz band. Racons using frequency agile transmitting 
techniques must include circuitry designed to reduce interference caused 
by triggering from radar antenna sidelobes.
    (i) Variable frequency ship station transponders operating in the 
2900-3100 MHz or 9300-9500 MHz band that are not used for search and 
rescue purposes must meet the following requirements:
    (1) Non-selectable transponders must have the following 
characteristics:
    (i) They must respond on all their frequencies with a maximum range 
error equivalent to 100 meters;
    (ii) They must use a Morse encoding of ``PS'' (dot-dash-dash-dot, 
dot-dot-dot), meaning ``You should not come any closer''. The width of a 
Morse dot is defined as equal to the width of a space and \1/3\ of the 
width of a Morse dash;
    (iii) When they employ swept frequency techniques they must not 
transmit on any frequency for more than 10 seconds in any 120 second 
period;

received signals below -10 dBm at the antenna input will not activate 
the transponder;
    (vii) Antenna polarization must be horizontal when operating in the 
9300-9500 MHz band and either horizontal or both horizontal and vertical 
when operating in the 2900-3100 MHz band.

circuitry designed to reduce interference caused by triggering from 
radar antenna sidelobes.
    (2) Selectable transponders must be authorized under part 5 of the 
Commission's rules until standards for their use are developed.
    (j) The transmitted signals of search and rescue transponders must 
cause to appear on a radar display a series of at least 20 equally 
spaced dots.

must not transmit on 2182 kHz during the silence periods for three 
minutes twice each hour beginning at x h.00 and x h.30 Coordinated 
Universal Time (UTC).
    (d) Each public coast station must provide assistance for distress 
communications when requested by the Coast Guard.



Sec. 80.302  Notice of discontinuance, reduction, or impairment of service 
involving a distress watch.

    (a) When changes occur in the operation of a public coast station 
which include discontinuance, reduction or suspension of a watch 
required to be maintained on 2182 kHz or 156.800 MHz, notification must 
be made by the licensee to the nearest district office of the U.S. Coast 
Guard as soon as practicable. The notification must include the 
estimated or known resumption time of the watch.
    (b) [Reserved]

[68 FR 46967, Aug. 7, 2003]



Sec. 80.303  Watch on 156.800 MHz (Channel 16).

    (a) During its hours of operation, each coast station operating in 
the 156-162 MHz band and serving rivers, bays and inland lakes except 
the Great Lakes, must maintain a safety watch on the frequency 156.800 
MHz except when transmitting on 156.800 MHz.
    (b) A coast station is exempt from compliance with the watch 
requirement when Federal, State, or Local Government stations maintain a 
watch on 156.800 MHz over 95% of the coast station's service area. Each 
licensee exempted by rule must notify the nearest district office of the 
U.S. Coast Guard at least thirty days prior to discontinuing the watch, 
or in the case of new stations, at least thirty days prior to commencing 
service. The Coast Guard may require any coast station to maintain the 
watch temporarily or permanently. The Coast Guard may also require any 
coast station to remain capable of either immediately resuming the watch 
or providing the Coast Guard direct dial-up access to the necessary 
156.800 MHz transceiver at no charge so that the Coast Guard can 
maintain the watch.
    (c) If the government station(s) providing the 156.800 MHz watch 
over the service area of an exempt station temporarily discontinues that 
watch, the exempt coast station upon receiving notice of this condition 
must maintain the watch on 156.800 HMz during the discontinuance. 
Automated maritime communications systems' compliance with this 
requirement is limited to the use of existing facilities.

Sec. 80.304  Watch requirement during silence periods.

    Each ship station operating on telephony on frequencies in the band 
1605-3500 kHz must maintain a watch on the frequency 2182 kHz. This 
watch must be maintained at least twice each hour for 3 minutes 
commencing at x h.00 and x h.30 Coordinated Universal Time (UTC) using 
either a loudspeaker or headphone. Expect for distress, urgency or 
safety messages, ship stations must not transmit during the silence 
periods on 2182 kHz.

[51 FR 31213, Sept. 2, 1986, as amended at 68 46967, Aug. 7, 2003]



Sec. 80.305  Watch requirements of the Communications Act and the Safety 
Convention.

    (a) Each ship of the United States which is equipped with a 
radiotelegraph station for compliance with part II of title III of the 
Communications Act or chapter IV of the Safety Convention must:
    (1) Keep a continuous and efficient watch on 500 kHz by means of 
radio officers while being navigated in the open sea outside a harbor or 
port. In lieu thereof, on a cargo ship equipped with a radiotelegraph 
auto alarm in proper operating condition, an efficient watch on 500 kHz 
must be maintained by means of a radio officer for at least 8 hours per 
day in the aggregate, i.e.,

[[Page 68]]

for at least one-third of each day or portion of each day that the 
vessel is navigated in the open sea outside of a harbor or port.
    (2) Keep a continuous and efficient watch on the radiotelephone 
distress frequency 2182 kHz from the principal radio operating position 
or the room from which the vessel is normally steered while being 
navigated in the open sea outside a harbor or port. A radiotelephone 
distress frequency watch receiver having a loudspeaker and a 
radiotelephone auto alarm facility must be used to keep the continuous 
watch on 2182 kHz if such watch is kept from the room from which the 
vessel is normally steered. After a determination by the master that 
conditions are such that maintenance of the listening watch would 
interfere with the safe navigation of the ship, the watch may be 
maintained by the use of the radiotelephone auto alarm facility alone.
    (3) Until February 1, 2005, keep a continuous and efficient watch on 
the VHF distress frequency 156.800 MHz from the room from which the 
vessel is normally steered while in the open sea outside a harbor or 
port. The watch must be maintained by a designated member of the crew 
who may perform other duties, relating to the operation or navigation of 
the vessel, provided such other duties do not interfere with the 
effectiveness of the watch. Use of a properly adjusted squelch or brief 
interruptions due to other nearby VHF transmissions are not considered 
to adversely affect the continuity or efficiency of the required watch 
on the VHF distress frequency. This watch need not be maintained by 
vessels subject to the Bridge-to-Bridge Act and participating in a 
Vessel Traffic Services (VTS) system as required or recommended by the 
U.S. Coast Guard, when an efficient listening watch is maintained on 
both the bridge-to-bridge frequency and a separate assigned VTS 
frequency.
    (b) Each cargo ship of the United States which is equipped with a 
radiotelephone station for compliance with part II of title III of the 
Communications Act or chapter IV of the Safety Convention must while 
being navigated outside of a harbor or port:
    (1) Keep a continuous watch on 2182 kHz in the room from which the 
vessel is normally steered while at sea, whenever such station is not 
being used for authorized traffic. Such watch must be maintained by at 
least one officer or crewmember who may perform other duties relating to 
the operation or navigation of the vessel, provided such other duties do 
not interfere with the watch. A radiotelephone watch receiver having a 
loudspeaker and a radiotelephone auto alarm must be used to keep the 
continuous watch on 2182 kHz. After a determination by the master that 
maintenance of the watch would interfere with the safe navigation of the 
ship, the watch may be maintained by use of the radiotelephone auto 
alarm facility alone.
    (2) Keep a continuous watch on 156.800 MHz from the room from which 
the vessel is normally steered. The watch must be maintained by a 
crewmember who may perform other duties, relating to the operation or 
navigation of the vessel, provided such other duties do not interfere 
with the watch. Use of properly adjusted squelch of brief interruptions 
due to other nearby VHF transmissions are not considered to adversely 
affect the watch. This watch need not be maintained by vessels subject 
to the Bridge-to-Bridge Act and participating in a Vessel Traffic 
Services (VTS) system when a watch is maintained on both the bridge-to-
bridge frequency and a VTS frequency.
    (c) Each vessel of the United States transporting more than six 
passengers for hire, which is equipped with a radiotelephone station for 
compliance with part III of title III of the Communications Act must, 
while being navigated in the open sea or any tidewater within the 
jurisdiction of the United States adjacent or contiguous to the open 
sea, keep a continuous watch on 2182 kHz while the vessel is beyond VHF 
communication range of the nearest VHF coast station, whenever the 
radiotelephone station is not being used for authorized traffic. A VHF 
watch must be kept on 156.800 MHz whenever such station is not being 
used for authorized traffic. The VHF watch must be maintained at the 
vessel's steering station actually in use by the qualified operator as 
defined by

[[Page 69]]

Sec. 80.157 or by a crewmember who may perform other duties relating to 
the operation or navigation of the vessel, provided such other duties do 
not interfere with the watch. The use of a properly adjusted squelch is 
not considered to adversely affect the watch. The VHF watch need not be 
maintained by vessels subject to the Bridge-to-Bridge Act and 
participating in a Vessel Traffic Services (VTS) system when an 
efficient listening watch is maintained on both the bridge-to-bridge 
frequency and a VTS frequency.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46967, Aug. 7, 2003]



Sec. 80.306  Provisions governing the radiotelegraph watch.

    (a) The radio officer must use the main or reserve receiver, and 
either headphones or a loudspeaker to keep the watch on 500 kHz.
    (b) During the watch, the radio officer may temporarily interrupt 
the required watch on 500 kHz while transmitting or receiving signals or 
messages to or from a station but only if it is not feasible to 
simultaneously handle such traffic and listen on 500 kHz by split 
headphones or a loudspeaker. The watch on 500 kHz must, however, without 
exception be maintained during the silence periods.
    (c) During this watch, on vessels subject to the Communications Act 
and the Safety Convention on international voyages, the radio officer 
may discontinue listening when handling traffic on other frequencies or 
performing other essential radio duties, but only if it is impracticable 
to listen by split headphones or loudspeaker. The watch must always be 
maintained by a radio officer using headphones or loudspeaker during the 
silence periods. The term ``essential radio duties'' in this rule 
includes urgent repairs of radio communication equipment used for safety 
or radio navigational equipment by order of the master.
    (d) When authorized by the master, the radio officer may perform 
maintenance repair of communications, navigation or other electronic 
equipment outside of the radiotelegraph room, provided that the 
listening watch on 500 kHz can be maintained by headphones, 
loudspeakers, portable receivers, or other suitable means. The watch on 
500 kHz must be maintained in the radiotelegraph room during the silence 
period.



Sec. 80.307  Compulsory use of radiotelegraph auto alarm.

    The radiotelegraph auto alarm required on a cargo ship subject to 
the radiotelegraph provisions of part II of title III of the 
Communications Act or the Safety Convention must be in operation, 
connected to the main antenna and adjusted for optimum efficiency at all 
times while the ship is being navigated in the open sea when a radio 
officer is not listening on the frequency 500 kHz, except under the 
circumstances as set forth in Sec. 80.306(b).



Sec. 80.308  Watch required by the Great Lakes Radio Agreement.

    (a) Each ship of the United States that is equipped with a 
radiotelephone station for compliance with the Great Lakes Radio 
Agreement must when underway keep a watch on:
    (1) 156.800 MHz on board a vessel 20 meters (65 feet) and over in 
length, a vessel engaged in towing (See Sec. 80.951(b)), or a vessel 
carrying more than 6 passengers for hire. This watch must be maintained 
whenever the station is not being used for authorized traffic. However, 
a watch on 156.800 MHz need not be maintained by a vessel maintaining a 
watch on the bridge-to-bridge frequency 156.650 MHz and participating in 
a Vessel Traffic Services (VTS) system and maintaining a watch on the 
specified VTS frequency.
    (2) 156.650 MHz on board a vessel 38 meters (124 feet) and over in 
length, a vessel engaged in towing (See Sec. 80.951(b)), or a vessel 
carrying more than six passengers for hire. This watch must be 
maintained continuously and effectively. Sequential monitoring is not 
sufficient. Portable VHF equipment may be used to meet this requirement. 
Vessels are exempted from this requirement while transiting the St. 
Lawrence Seaway and complying with the Joint Regulations of the St. 
Lawrence Seaway Authority and St. Lawrence Seaway Development 
Corporation between the lower exit of St.

[[Page 70]]

Lambert Lock at Montreal and Crossover Island, New York and in the 
Welland Canal and approaches between Calling in Point No. 15 and No. 16.
    (b) The watch must be maintained by the master, or person designated 
by the master, who may perform other duties provided they do not 
interfere with the effectiveness of the watch.

[53 FR 17052, May 13, 1988]



Sec. 80.309  Watch required by the Bridge-to-Bridge Act.

    In addition to the watch requirement contained in Sec. 80.148, all 
vessels subject to the Bridge-to-Bridge Act must keep a watch on the 
designated navigational frequency. The watch must be maintained by the 
master or person in charge of the vessel or the person designated by the 
master or person in charge to pilot or direct the movement of the 
vessel. The person standing watch may perform other duties provided such 
other duties do not interfere with the watch.

[51 FR 31213, Sept. 2, 1986, as amended at 57 FR 61012, Dec. 23, 1992]



Sec. 80.310  Watch required by voluntary vessels.

    Voluntary vessels not equipped with DSC must maintain a watch on 
156.800 MHz (Channel 16) whenever the vessel is underway and the radio 
is not being used to communicate. Noncommercial vessels, such as 
recreational boats, may alternatively maintain a watch on 156.450 MHz 
(Channel 9) for call and reply purposes. Voluntary vessels equipped with 
VHF-DSC equipment must maintain a watch on either 156.525 MHz (Channel 
70) or VHF Channel 16 aurally whenever the vessel is underway and the 
radio is not being used to communicate. Voluntary vessels equipped with 
MF-HF DSC equipment must have the radio turned on and set to an 
appropriate DSC distress calling channel or one of the radiotelephone 
distress channels whenever the vessel is underway and the radio is not 
being used to communicate. Voluntary vessels equipped with Inmarsat A,

             Distress, Alarm, Urgency and Safety Procedures



Sec. 80.311  Authority for distress transmission.

    A mobile station in distress may use any means at its disposal to 
attract attention, make known its position, and obtain help. A distress 
call and message, however, must be transmitted only on the authority of 
the master or person responsible for the mobile station. No person shall 
knowingly transmit, or cause to be transmitted, any false or fraudulent 
signal of distress or related communication.



Sec. 80.312  Priority of distress transmissions.

    The distress call has absolute priority over all other 
transmissions. All stations which hear it must immediately cease any 
transmission capable of interfering with the distress traffic and must 
continue to listen on the frequency used for the emission of the 
distress call. This call must not be addressed to a particular station. 
Acknowledgement of receipt must not be given before the distress message 
which follows it is sent.



Sec. 80.313  Frequencies for use in distress.

    The frequencies specified in the bands below are for use by mobile 
stations in distress. The conventional emission is shown. When a ship 
station cannot transmit on the designated frequency or the conventional 
emission, it may use any available frequency or emission. Frequencies 
for distress and safety calling using digital selective calling 
techniques are listed in Sec. 80.359(b). Distress and safety NB-DP 
frequencies are indicated by footnote 2 in Sec. 80.361(b).

station in distress, spoken three times.
    (b) The procedures for canceling false distress alerts are contained 
in Sec. 80.335.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46968, Aug. 7, 2003]



Sec. 80.316  Distress messages.

    (a) The radiotelephone distress message consists of:
    (1) The distress signal MAYDAY;
    (2) The name of the mobile station in distress;
    (3) Particulars of its position;
    (4) The nature of the distress;
    (5) The kind of assistance desired;
    (6) Any other information which might facilitate rescue, for 
example, the length, color, and type of vessel, number of persons on 
board.
    (b) As a general rule, a ship must signal its position in latitude 
and longitude, using figures for the degrees and minutes, together with 
one of the words NORTH or SOUTH and one of the words EAST or WEST. In 
radiotelegraphy, the signal .-.-.- must be used to separate the degrees 
from the minutes. When practicable, the true bearing and distance in 
nautical miles from a known geographical position may be given.
    (c) The procedures for canceling false distress alerts are contained 
in Sec. 80.335.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46968, Aug. 7, 2003]



Sec. 80.317  Radiotelegraph and radiotelephone alarm signals.

    (a) The international radiotelegraph alarm signal consists of a 
series of twelve dashes sent in one minute, the duration of each dash 
being four seconds and the duration of the interval between consecutive 
dashes one second. The purpose of this special signal is the actuation 
of automatic devices giving the alarm to attract the attention of the 
operator when there is no listening watch on the distress frequency.
    (b) The international radiotelephone alarm signal consists of two 
substantially sinusoidal audio frequency tones transmitted alternately. 
One tone must have a frequency of 2200 Hertz and the other a frequency 
of 1300 Hertz, the duration of each tone being 250 milliseconds. When 
generated by automatic means, the radiotelephone alarm signal must be 
transmitted continuously for a period of at least 30 seconds, but not 
exceeding one minute; when generated by other means, the signal must be 
transmitted as continuously as practicable over a period of 
approximately one minute. The purpose of this special signal is to 
attract the attention of the person on watch or to actuate automatic 
devices giving the alarm.



Sec. 80.318  Use of alarm signals.

    (a) The radiotelegraph or radiotelephone alarm signal, as 
appropriate, must only be used to announce:
    (1) That a distress call or message is about to follow;
    (2) The transmission of an urgent cyclone warning. In this case the 
alarm

[[Page 72]]

signal may only be used by coast stations authorized by the Commission 
to do so; or
    (3) The loss of a person or persons overboard. In this case the 
alarm signal may only be used when the assistance of other ships is 
required and cannot be satisfactorily obtained by the use of the urgency 
signal only, but the alarm signal must not be repeated by other 
stations. The message must be preceded by the urgency signal.
    (b) In cases described in paragraphs (a)(2) and (3) of this section, 
the transmission of the warning or message by radiotelegraphy must not 
begin until two minutes after the end of the radiotelegraph alarm 
signal.



Sec. 80.319  Radiotelegraph distress call and message transmission procedure.

    (a) The radiotelegraph distress procedure consists of the following 
six steps: however, when time is vital, the first and second steps may 
be omitted. These two steps of the distress procedure may also be 
omitted in circumstances when transmission of the alarm signal is 
considered unnecessary:
    (1) The radiotelegraph alarm signal;
    (2) The distress call and an interval of two minutes;
    (3) The distress call;
    (4) The distress message;
    (5) Two dashes of ten to fifteen seconds each;
    (6) The call sign of the mobile station in distress.
    (b) The radiotelegraph distress transmissions must be sent by means 
of the international Morse code at a speed not exceeding 16 words per 
minute nor less than 8 words per minute.
    (c) The distress message, preceded by the distress call, must be 
repeated at intervals, especially during the 500 kHz international 
silence periods, until an answer is received. The radiotelegraph alarm 
signal may also be repeated, if necessary.
    (d) The transmissions under paragraphs (a) (5) and (6) of this 
section, which are to permit direction finding stations to determine the 
position of the station in distress, may be repeated at frequent 
intervals if necessary.
    (e) When the mobile station in distress receives no answer to a 
distress message transmitted on the distress frequency, the message may 
be repeated on any other available frequency on which attention might be 
attracted.



Sec. 80.320  Radiotelephone distress call and message transmission procedure.

    (a) The radiotelephone distress procedure consists of:
    (1) The radiotelephone alarm signal (whenever possible);
    (2) The distress call;
    (3) The distress message.
    (b) The DSC distress procedure consists of:
    (1) Transmission by a mobile unit in distress;
    (2) Reception;
    (3) Acknowledgement of distress calls;
    (4) Distress relays.
    (c) Radiotelephone distress transmissions must be made slowly and 
distinctly, each word being clearly pronounced to facilitate 
transcription.
    (d) After the transmission by radiotelephony of its distress 
message, the mobile station may be requested to transmit suitable 
signals followed by its call sign or name, to permit direction-finding 
stations to determine its position. This request may be repeated at 
frequent intervals if necessary.
    (e) The distress message, preceded by the distress call, must be 
repeated at intervals until an answer is received. This repetition must 
be preceded by the radiotelephone alarm signal whenever possible.
    (f) When the mobile station in distress receives no answer to a 
distress message transmitted on the distress frequency, the message may 
be repeated on any other available frequency on which attention might be 
attracted.

[51 FR 31213, Sept. 2, 1986, as amended



Sec. 80.321  Acknowledgement of receipt of distress message.

    (a) Stations of the maritime mobile service which receive a distress 
message from a mobile station which is beyond any possible doubt in 
their vicinity must immediately acknowledge receipt. However, in areas 
where reliable communication with one or more coast

[[Page 73]]

stations is practicable, ship stations may defer this acknowledgement 
for a short interval so that a coast station may acknowledge receipt.
    (b) Stations of the maritime mobile service which receive a distress 
message from a mobile station which beyond any possible doubt is not in 
their vicinity, must allow a short interval of time to elapse before 
acknowledging receipt of the message in order to permit stations nearer 
to the mobile station in distress to acknowledge receipt without 
interference.



Sec. 80.322  Form of acknowledgement.

    (a) The acknowledgement of receipt of a radiotelegraph distress 
message is transmitted in the following form:
    (1) The distress signal SOS;
    (2) The call sign of the station sending the distress message, sent 
three times;
    (3) The word DE;
    (4) The call sign of the station acknowledging receipt, sent three 
times;
    (5) The group RRR;
    (6) The message signal SOS.
    (b) The acknowledgement of receipt of a radiotelephone distress 
message is transmitted in the following form:
    (1) The distress signal MAYDAY;
    (2) The call sign or other identification of the station sending the 
distress message, spoken three times;
    (3) The words THIS IS;
    (4) The call sign or other identification of the station 
acknowledging receipt, spoken three times;
    (5) The word RECEIVED;
    (6) The distress signal MAYDAY.



Sec. 80.323  Information furnished by an acknowledging station.

    (a) Every mobile station which acknowledges receipt of a distress 
message must on the order of the master or person responsible for the 
ship, aircraft, or other vehicle carrying such mobile station, transmit 
as soon as possible the following information in the order shown:
    (1) Its identifier;
    (2) Its position;
    (3) The speed at which it is proceeding towards, and the approximate 
time it will take to reach the mobile station in distress.
    (b) Before sending this message, the station must ensure that it 
will not interfere with the emissions of other stations better situated 
to render immediate assistance to the station in distress.



Sec. 80.324  Transmission of distress message by station not itself in 
distress.

    (a) A mobile station or a land station which learns that a mobile 
station is in distress must transmit a distress message in any of the 
following cases:
    (1) When the station in distress cannot transmit the distress 
message.
    (2) When the master or person responsible for the ship, aircraft, or 
other vehicle not in distress, or for the land station, believes that 
further help is necessary.
    (3) When, although not in a position to assist, it has heard a 
distress message which has not been acknowledged. When a mobile station 
transmits such a distress message, it must notify the authorities who 
may be able to assist.
    (b) Transmission must be made on the international distress 
frequencies or on any other available frequency on which attention might 
be attracted.
    (c) Transmission of the distress message must always be preceded by 
the call indicated below, which must itself be preceded whenever 
possible by the radiotelegraph or radiotelephone alarm signal. This call 
consists of:
    (1) When radiotelegraphy is used:
    (i) The signal DDD SOS SOS SOS DDD:
    (ii) The word DE;
    (iii) The call sign of the transmitting station, sent three times.
    (2) When radiotelephony is used:
    (i) The signal MAYDAY RELAY, spoken three times;
    (ii) The words THIS IS;
    (iii) The call sign or other identification of the transmitting 
station, spoken three times.
    (d) When the radiotelegraph alarm signal is used, an interval of two 
minutes must be allowed, whenever this is considered necessary, before 
the transmission of the call mentioned in paragraph (c)(1) of this 
section.

[[Page 74]]



Sec. 80.325  Control of distress traffic.

    (a) Distress traffic consists of all messages relating to the 
immediate assistance required by the mobile station in distress. In 
distress traffic, the distress signal must be sent before the call and 
at the beginning of the preamble of any radiotelegram.
    (b) The control of distress traffic is the responsibility of the 
mobile station in distress or of the station which has sent the distress 
message. These stations may delegate the control of the distress traffic 
to another station.
    (c) The station in distress or the station in control of distress 
traffic may impose silence either on all stations of the mobile service 
in the area or on any station which interferes with the distress 
traffic. It must address these instructions ``to all stations'' or to 
one station only, according to circumstances. In either case, it must 
use one of the following signals which are reserved for use by the 
mobile station in distress and for the station controlling distress 
traffic:
    (1) In radiotelegraphy, the abbreviation QRT, followed by the 
distress signal SOS.
    (2) In radiotelephony, the signal SEELONCE MAYDAY.
    (d) If essential, any station of the mobile service near the ship, 
aircraft, or other vehicle in distress may also impose silence. It must 
use for this purpose:
    (1) In radiotelegraphy, the abbreviation QRT, followed by the word 
DISTRESS and its own call sign;
    (2) In radiotelephony, the word SEELONCE, followed by the word 
DISTRESS and its own call sign or other identification.



Sec. 80.326  Notification of resumption of normal working.

    (a) When distress traffic has ceased, or when complete silence is no 
longer necessary on a frequency which has been used for distress 
traffic, the station which has controlled this traffic must transmit on 
that frequency a message addressed ``to all stations'' indicating that 
normal working may be resumed.
    (1) In radiotelegraphy, this message consists of:
    (i) The distress signal SOS;
    (ii) The call ``to all stations'' (CQ), sent three times;
    (iii) The word DE;
    (iv) The call sign of the station sending the message;
    (v) The time of handing in the message;
    (vi) The name and call sign of the mobile station which was in 
distress;
    (vii) The service abbreviation QUM.
    (2) In radiotelephony, this message consists of:
    (i) The distress signal MAYDAY;
    (ii) The call ``Hello all stations'', spoken three times;
    (iii) The words THIS IS;
    (iv) The call sign or other identification of the station sending 
the message;
    (v) The time of handing in of the message;
    (vi) The name and call sign of the mobile station which was in 
distress;
    (vii) The words SEELONCE FEENEE OR PRU-DONCE.
    (b) Until they receive the foregoing message indicating that normal 
or limited working may be resumed, all stations which are aware of the 
distress traffic, and which are not taking part in it, are forbidden to 
transmit on the frequencies on which the distress traffic is taking 
place.



Sec. 80.327  Urgency signals.

    (a) The urgency signal indicates that the calling station has a very 
urgent message to transmit concerning the safety of a ship, aircraft, or 
other vehicle, or the safety of a person. The urgency signal must be 
sent only on the authority of the master or person responsible for the 
mobile station.
    (b) In radiotelegraphy, the urgency signal consists of three 
repetitions of the group XXX, sent with the individual letters of each 
group, and the successive groups clearly separated from each other. It 
must be transmitted before the call.
    (c) In radiotelephony, the urgency signal consists of three oral 
repetitions of the group of words PAN PAN transmitted before the call.
    (d) The urgency signal has priority over all other communications 
except distress. All mobile and land stations which hear it must not 
interfere with

[[Page 75]]

the transmission of the message which follows the urgency signal.

[51 FR 31213, Sept. 2, 1986, as amended at 52 FR 35245, Sept. 18, 1987]



Sec. 80.328  Urgency message.

    (a) The urgency signal and call, and the message following it, must 
be sent on one of the international distress frequencies. Stations which 
cannot transmit on a distress frequency may use any other available 
frequency on which attention might be attracted.
    (b) Mobile stations which hear the urgency signal must continue to 
listen for at least three minutes. At the end of this period, if no 
urgency message has been heard, they may resume their normal service. 
However, land and mobile stations which are in communication on 
frequencies other than those used for the transmission of the urgency 
signal and of the call which follows it may continue their normal work 
without interruption provided the urgency message is not addressed ``to 
all stations''.
    (c) When the urgency signal has been sent before transmitting a 
message ``to all stations'' which calls for action by the stations 
receiving the message, the station responsible for its transmission must 
cancel it as soon as it knows that action is no longer necessary. This 
message of cancellation must likewise be addressed ``to all stations''.



Sec. 80.329  Safety signals.

    (a) The safety signal indicates that the station is about to 
transmit a message concerning the safety of navigation or giving 
important meteorological warnings.
    (b) In radiotelegraphy, the safety signal consists of three 
repetitions of the group TTT, sent with the individual letters of each 
group, and the successive groups clearly separated from each other. It 
must be sent before the call.
    (c) In radiotelephony, the safety signal consists of the word 
SECURITE, pronounced as in French, spoken three times and transmitted 
before the call.
    (d) The safety signal and call must be sent on one of the 
international distress frequencies (500 kHz or 8364 kHz radiotelegraph; 
2182 kHz or 156.8 MHz radiotelephone). Stations which cannot transmit on 
a distress frequency may use any other available frequency on which 
attention might be attracted.



Sec. 80.330  Safety message.

    (a) The safety signal and call must be followed by the safety 
message. Where practicable, the safety message should be sent on a 
working frequency, and a suitable announcement to this effect must be 
made at the end of the call.
    (b) Except for the cases mentioned in paragraph (c) of this section, 
the safety signal when sent on the frequency 500 kHz must be transmitted 
toward the end of the first available silence period; the safety message 
must be transmitted immediately after the silence period.
    (c) Messages about meteorological warnings, of cyclones, dangerous 
ice, dangerous wrecks, or any other imminent danger to marine navigation 
must be preceded by the safety signal.
    (d) Stations hearing the safety signal must not make any 
transmission likely to interfere with the message.



Sec. 80.331  Bridge-to-bridge communication procedure.

    (a) Vessels subject to the Bridge-to-Bridge Act transmitting on the 
designated navigational frequency must conduct communications in a 
format similar to those given below:
    (1) This is the (name of vessel). My position is (give readily 
identifiable position, course and speed) about to (describe contemplated 
action). Out.
    (2) Vessel off (give a readily identifiable position). This is (name 
of vessel) off (give a readily identifiable position). I plan to (give 
proposed course of action). Over.
    (3) (Coast station), this is (vessel's name) off (give readily 
identifiable position). I plan to (give proposed course of action). 
Over.
    (b) Vessels acknowledging receipt must answer ``(Name of vessel 
calling). This is (Name of vessel answering). Received your call,'' and 
follow with an indication of their intentions. Communications must 
terminate when each ship is satisfied that the other no longer poses a 
threat to its safety and is ended with ``Out''.
    (c) Use of power greater than 1 watt in a bridge-to-bridge station 
shall be

[[Page 76]]

limited to the following three situations:
    (1) Emergency.
    (2) Failure of the vessel being called to respond to a second call 
at low power.
    (3) A broadcast call as in paragraph (a)(1) of this section in a 
blind situation, e.g., rounding a bend in a river.



Sec. 80.332  Equipment to aid search and rescue operations.

    (a) Survival craft stations may transmit distress, urgency and 
safety signals, calls and messages.
    (b) EPIRB's may transmit only in accordance with the requirements of 
subparts V and X of this part.



Sec. 80.333  Stations in the maritime mobile-satellite service.

    The provisions of Sec. Sec. 80.311 and 80.324 apply to the 
operations of ship earth stations in the maritime mobile-satellite 
service.



Sec. 80.334  False distress alerts.

    A distress alert is false if it was transmitted without any 
indication that a mobile unit or person was in distress and required 
immediate assistance. Transmitting a false distress alert is prohibited 
and may be subject to the provisions of part 1, subpart A of this 
chapter if that alert:
    (a) Was transmitted intentionally;
    (b) Was not cancelled in accordance with Sec. 80.335;
    (c) Could not be verified as a result of either the ship's failure 
to keep watch on appropriate frequencies in accordance with Sec. 
80.1123 or subpart G of this part, or its failure to respond to calls 
from the U.S. Coast Guard;
    (d) Was repeated; or
    (e) Was transmitted using a false identity.

[68 FR 46968, Aug. 7, 2003]



Sec. 80.335  Procedures for canceling false distress alerts.

    If a distress alert is inadvertently transmitted, the following 
steps shall be taken to cancel the distress alert.
    (a) VHF Digital Selective Calling.
    (1) Reset the equipment immediately;
    (2) Transmit a DSC distress alert cancellation (i.e., own ship's 
acknowledgment), if that feature is available;
    (3) Set to Channel 16; and
    (4) Transmit a broadcast message to ``All stations'' giving the 
ship's name, call sign or registration number, and MMSI, and cancel the 
false distress alert.
    (b) MF Digital Selective Calling.
    (1) Reset the equipment immediately;
    (2) Transmit a DSC distress alert cancellation (i.e., own ship's 
acknowledgment), if that feature is available;
    (3) Tune for radiotelephony transmission on 2182 kHz; and
    (4) Transmit a broadcast message to ``All stations'' giving the 
ship's name, call sign or registration number, and MMSI, and cancel the 
false distress alert.
    (c) HF Digital Selective Calling;
    (1) Reset the equipment immediately;
    (2) Transmit a DSC distress alert cancellation (i.e., own ship's 
acknowledgment), if that feature is available, on each frequency on 
which the distress alert was transmitted;
    (3) Tune for radiotelephony on the distress and safety frequency in 
each band in which a false distress alert was transmitted; and
    (4) Transmit a broadcast message to ``All stations'' giving the 
ship's name, call sign or registration number, and MMSI, and cancel the 
false distress alert frequency in each band in which a false distress 
alert was transmitted.
    (d) INMARSAT ship earth station. Immediately notify the appropriate 
rescue coordination center that the alert is cancelled by sending a 
distress priority message by way of the same land earth station through 
which the false distress alert was sent. Provide ship name, call sign or 
registration number, and INMARSAT identity with the cancelled alert 
message.
    (e) EPIRB. If for any reason an EPIRB is activated inadvertently, 
immediately contact the nearest U.S. Coast Guard unit or appropriate 
rescue coordination center by telephone, radio or ship earth station and 
cancel the distress alert.
    (f) General and other distress alerting systems. Notwithstanding 
paragraphs (a) through (e) of this section, ships may use additional 
appropriate means available to them to inform the nearest appropriate 
U.S. Coast Guard rescue coordination center that a false

[[Page 77]]

distress alert has been transmitted and should be cancelled.

                          Subpart H_Frequencies

                             Radiotelegraphy



Sec. 80.351  Scope.

    The following sections describe the carrier frequencies and general 
uses of radiotelegraphy with respect to the following:

--Distress, urgency, safety, call and reply.
--Working.
--Digital selective calling (DSC).
--Narrow-band direct-printing (NB-DP).
--Facsimile.



Sec. 80.353  [Reserved]



Sec. 80.355  Distress, urgency, safety, call and reply Morse code frequencies.

    This section describes the distress, urgency, safety, call and reply 
carrier frequencies assignable to stations for Morse code 
radiotelegraphy.
    (a) Frequencies in the 100-160 kHz band. The international calling 
frequency in the 100-160 kHz band is 143 kHz using A1A or J2A emission. 
When a ship station operating in the 100-160 kHz band desires to 
communicate with a coast station, it must call on the frequency 143 kHz 
unless the International List of Coast Stations provides otherwise. 
Coast stations must reply on their normal working frequency in this 
band. Only individual calls, replies to such calls, and transmission of 
signals preparatory to traffic may be transmitted on 143 kHz.
    (b) Frequencies in the 405-535 kHz band. (1) The international 
distress, urgency, safety, call and reply frequency used by ship and 
coast stations operating in the 405-525 kHz band is 500 kHz. A2A and A2B 
or H2A and H2B emissions are preferred for distress calls, distress 
traffic and for urgency and safety messages. For call and reply messages 
A1A or J2A emission must be used. In order to facilitate distress 
communications routine correspondence tranmissions on 500 kHz must be 
reduced to a minimum.
    (2) In Region 2 and areas of heavy traffic ship stations must 
request coast stations to listen on the ship station's working 
frequencies.
    (3) In areas where 500 kHz is used for distress a ship or coast 
station must use the supplementary calling frequency 512 kHz for routine 
calling and normally request a reply on its working frequency. The 
called station may reply on 512 kHz when requested to do so by the 
calling station.
    (c) Frequencies in the 2000-27500 kHz band--(1) Ship station 
frequencies. The following table describes the calling frequencies in 
the 4000-27500 kHz band which are available for use by authorized ship 
stations equipped with crystal-controlled oscillators for A1A, J2A, J2B, 
or J2D radiotelegraphy. There are two series of frequencies for 
worldwide use and two series of frequencies for each geographic region. 
Ship stations with synthesized transmitters may operate on every full 
100 Hz increment in the 0.5 kHz channel for the frequencies listed, 
except for 100 Hz above and below those designated for worldwide use. 
During normal business hours when not communicating on other 
frequencies, all U.S. coast radiotelegraph stations must monitor the 
worldwide frequencies and the initial calling frequencies for the region 
in which it is located. The specific frequencies which must be monitored 
by a coast station will vary with propagation conditions. The calling 
frequencies which are routinely monitored by specific coast stations can 
be determined by reference to the ITU publication entitled ``List of 
Coast Stations.'' Initial calls by ship stations must be made on the 
appropriate initial calling frequency first. Calls on the worldwide 
frequencies may be made only after calls on the appropriate initial 
calling frequency are unsuccessful.

Sec. 80.357  Working frequencies for Morse code and data transmission.

    This section describes the working frequencies assignable to 
maritime stations for A1A, J2A, J2B (2000-27500 kHz band only), or J2D 
(2000-27500 kHz band only) radiotelegraphy.
    (a) Ship station frequencies--(1) Frequencies in the 100-160 kHz 
band. The following table describes the working carrier frequencies in 
the 100-160 kHz band which are assignable to ship stations. A ship 
station may also transmit on a radiotelegraphy working channel of a 
coast station within the 100-160 kHz band when directed to do so by the 
coast station provided interference is not caused to any land, fixed, 
broadcast, or radiolocation station.

    (2) Frequencies in the 405-525 kHz band. The following table 
describes the working carrier frequencies in the 405-525 kHz band which 
are assignable to ship stations. A ship station may transmit on a 
radiotelegraphy working channel of a coast station in the 415-490 kHz 
band when directed to do so by the coast station.

\1\ The frequency 410 kHz may be used on a secondary basis for the
  transmission of radiodetermination information and for transmitting by
  radiotelegraph radiodetermination related messages to direction-
  finding stations.
\2\ The frequency 512 kHz may be used as a supplementary calling
  frequency when 500 kHz is used for distress, safety and urgency
  communications. The use of the 512 kHz as a working frequency is
  prohibited in areas where it is used as a supplementary calling
  frequency when 500 kHz is used for distress, safety, and urgency
  communications.
\3\ The frequency 518 kHz is a receive only frequency by ship stations.
  It is used by U.S. Coast Guard coast stations for NB-DP transmissions
  of meteorological and navigational warnings to ships.

    (3) Frequencies in the 2000-27500 kHz band. This paragraph describes 
the working frequencies and Channel Series in the 2000-27500 kHz band 
which are assignable to ship stations.
    (i) Two Channel Series will be assigned for routine use to each ship 
station. Frequencies from any other Channel Series may be used if the 
frequencies in the assigned Channel Series are not adequate for 
communications.

\1\ All frequencies in this table are shown in kilohertz.

    (2) Conditions of use. The following conditions are applicable to 
these frequencies:
    (i) Frequencies in the 100-160 kHz band are assignable to coast 
stations for high seas communications only;
    (ii) Frequencies above 5 MHz may be assigned primarily to stations 
serving the high seas and secondarily to stations serving inland waters 
of the United States, including the Great Lakes, under the condition 
that interference will not be caused to any coast station serving the 
high seas.

[[Page 84]]

    (iii) The frequency 410 kHz may be used on a secondary basis for the 
transmission of radiodetermination information and for transmitting by 
radiotelegraph radiodetermination messages to direction-finding 
stations; and
    (iv) The frequency 512 kHz may be used as a supplementary calling 
frequency when 500 kHz is used for distress, urgency and safety 
communications. The use of the 512 kHz as a working frequency is 
prohibited in areas where 500 kHz is used for distress, urgency and 
safety communications.

Sec. 80.359  Frequencies for digital selective calling (DSC).

    (a) General purpose calling. The following table describes the 
calling frequencies for use by authorized ship and coast stations for 
general purpose DSC. There are three series of paried frequencies. One 
series is for worldwide use; the other two series are for regional use. 
The ``Series A'' designation includes coast stations along, and ship 
stations in, the Atlantic Ocean, the Gulf of Mexico, and the Caribbean 
Sea. The ``Series B'' designation includes stations in any remaining 
areas. Stations must initiate contact on the appropriate regional 
frequency depending upon the location of the called station and 
propagation conditions. Acknowledgement is made on the paired frequency. 
The worldwide frequencies may be used for international calling, if 
calls on the appropriate regional frequencies are unsuccessful, or the 
regional series does not contain the appropriate band (e.g., 2 MHz). 
During normal working hours, all public coast stations capable of DSC 
operations must monitor the worldwide and regional frequencies 
appropriate for its location. The specific frequencies to be monitored 
will vary with propagation conditions.

frequency in areas of heavy usage of 2182 kHz. All stations

[[Page 93]]

must use J3E emission when operating on 2182 and 2191 kHz, except that:
    (1) H3E emission may be used on 2182 kHz for communications with 
foreign coast and ship stations; or,
    (2) A3E emission may be used on 2182 kHz by portable survival craft 
stations, or transmitters authorized for use prior to January 1, 1972. 
See Sec. 80.203(c).
    (b) The frequencies 4125.0 kHz, 6215 kHz, 8291 kHz, 12290 kHz, and 
16420 kHz may be used by coast and ship stations on a simplex basis for 
distress and safety communications. The frequency 4125.0 kHz may also be 
used for distress and safety communications between aircraft and 
maritime mobile stations.
    (c) The frequency 5167.5 kHz is available to any station for 
emergency communications in the State of Alaska. Peak envelope power of 
stations operating on this frequency must not exceed 150 watts. This 
frequency may also be used by Alaska private fixed stations for calling 
and listening, but only for establishing communication.
    (d) In the 4000-27500 kHz band, the following coast frequencies are 
available for assignment to public coast stations for call and reply 
communications. The paired ship frequencies are available for use by

\1\ Unlimited hours of use from December 15 to April 1 and day only from
  April 1 to December 15. Harmful interference must not be caused to any
  station in the Great Lakes region.
\2\ In the Great Lakes region 2206 kHz is not available for transmission
  to U.S. ships except in the case of distress. U.S. coast stations in
  the Great Lakes area may use 2514, 2550 and 2582 kHz on a shared basis
  with coast stations of Canada. Except in the case of distress, the
  frequency 2550 kHz must not be used for transmission to ship stations
  of Canada since the associated ship station transmit frequency 2158
  kHz is not available to Canadian ship stations for transmission and
  2582 kHz must not be used for public correspondence transmissions to
  U.S. ship stations since the associated ship transmit frequency 2206
  kHz is not available to U.S. ship stations for transmissions except in
  the case of distress.
\3\ Limited to a peak envelope power of 150 watts.
\4\ Harmful interference must not be caused to any coast station in the
  Caribbean region.
\5\ But see section 80.373(c)(3) of this chapter.

    (b) Working frequencies in the 4000-27500 kHz band. This paragraph 
describes the working carrier frequencies in the 4000-27500 kHz band. 
With respect to frequencies that are assignable in more than one 
geographical area, once the frequency is assigned to one licensee, any 
subsequent license will be authorized on a secondary, non-interference 
basis with respect to the incumbent license's existing operation. If the 
first licensee later seeks authorization to operate in an additional 
geographic area, such authorization will be on a secondary, non-
interference basis to other co-channel licensees.
    (1) The following table specifies the carrier frequencies available 
for assignment to public coast stations. The paired ship frequencies are 
available for use by authorized ship stations. The specific frequency 
assignment available to public coast stations for a particular 
geographic area is indicated by an ``x'' under the appropriate column. 
The allotment areas are in accordance with the ``Standard Defined 
Areas'' as identified in the International Radio Regulations, Appendix 
25 Planning System, and indicated in the preface to the International 
Frequency List (IFL).

                                               Working Carrier Frequency Pairs in the 4000-27500 kHz Band

    (2) The following table specifies the non-paired carrier frequencies 
that are available for assignment to public coast stations for simplex 
operations. These frequencies are available for use by authorized ship 
stations for transmissions to coast stations (simplex operations). 
Assignments on these frequencies must accept interference. They are 
shared with government users and are considered ``common use'' 
frequencies under the international Radio Regulations. They cannot be 
notified for inclusion in the Master International Frequency Register, 
which provides stations with interference protection, but may be listed 
in the international List of Coast Stations. (See Radio Regulation No. 
1220 and Recommendation 304.)

  activities.

    (ii) Service areas in the marine VHF 156-162 MHz band are VHF Public 
Coast Station Areas (VPCSAs). As listed in the table in this paragraph, 
VPCSAs are based on, and composed of one or more of, the U.S. Department 
of Commerce's 172 Economic Areas (EAs). See 60 FR 13114 (March 10, 
1995). In addition, the Commission shall treat Guam and the Northern 
Mariana Islands, Puerto Rico and the United States Virgin Islands, 
American Samoa, and the Gulf of Mexico as EA-like areas 173-176, 
respectively. Maps of the EAs and VPCSAs are available for public 
inspection and copying at the Federal Communications Commission, Public 
Safety and Private Wireless Division, 445 12th St., SW., Room 4-C330, 
Washington, DC. Except as shown in the table, the frequency pairs listed 
in paragraph (c)(1)(i) of this section are available for assignment to a

    (iii) Subject to paragraph (c)(3) of this section, each licensee may 
also operate on 12.5 kHz offset frequencies in areas where the licensee 
is authorized on both frequencies adjacent to the offset frequency, and 
in areas where the licensee on the other side of the offset frequency 
consents to the licensee's use of the adjacent offset frequency.
    (2) Any recovered channel pairs will revert automatically to the 
holder of the VPCSA license within which such channels are included, 
except the channel pairs listed in the table in paragraph (c)(1)(ii) of 
this section. Those channel pairs, and any channel pairs recovered where 
there is no VPCSA licensee, will be retained by the Commission for 
future licensing.
    (3) VPCSA licensees may not operate on Channel 228B (162.0125 MHz), 
which is available for use in the Coast Guard's Ports and Waterways 
Safety System (PAWSS)). In addition, within six months of the conclusion 
of the competitive bidding procedures to determine the licensees in each 
VPCSA, the U.S. Coast Guard shall submit to each licensee of VPCSAs 1-9 
a plan specifying up to two narrowband channel pairs offset 12.5 kHz 
from the channels set forth in the table in paragraph (c)(1)(i) of this 
section, for use in the PAWSS. The final selection of the PAWSS channel 
pairs can be negotiated (if the VPCSA licensee objects to the Coast 
Guard proposal, it shall make a counterproposal within three months) and 
established by an agreement between the parties. All parties are 
required to negotiate in good faith. If no agreement is reached within 
one year of the date the Coast Guard submitted its plan, the Coast Guard 
may petition the Commission to select the channel pairs.
    (4) Subject to the requirements of Sec. 1.924 of this chapter and 
Sec. 80.21, each VPCSA licensee may place stations anywhere within its 
region without obtaining prior Commission approval provided:
    (i) It provides to co-channel coast station incumbent licensees, and 
incumbent Private Land Mobile Radio licensees authorized under part 90 
of this chapter on a primary basis, protection as defined in subpart P 
of this part. VPCSA licensees that share a common border may either 
distribute the available frequencies upon mutual agreement or request 
that the Commission assign frequencies along the common border.
    (ii) The locations and/or technical parameters of the transmitters 
are such that individual coordination of the channel assignment(s) with 
a foreign administration, under applicable international agreements and 
rules in this part, is not required.
    (iii) For any construction or alteration that would exceed the 
requirements of Sec. 17.7 of this chapter, licensees must notify the 
appropriate Regional Office of the Federal Aviation Administration (FAA 
Form 7460-1) and file a request for antenna height clearance and 
obstruction marking and lighting specifications (FCC Form 854) with the 
FCC, Attn: Information Processing Branch, 1270 Fairfield Rd., 
Gettysburg, PA 17325-7245.
    (iv) The transmitters must not have a significant environmental 
effect as defined by Sec. Sec. 1.1301 through 1.1319 of this chapter.
    (d) Working frequencies in the Mississippi River System. The 
Mississippi River System includes the Mississippi River and connecting 
navigable waters other than the Great Lakes. The following simplex 
frequencies are available for assignment to public coast stations 
serving the Mississippi River System for radiotelephony communications. 
These simplex frequencies also are available for use by authorized ship 
stations within communication service range, whether or not the ship is 
operating within the confines of the Mississippi River System.

    (4) Channels in the 219-220 MHz band are also used on a secondary, 
non-interference basis by amateur stations participating in digital 
message forwarding systems. Amateur stations may not cause harmful 
interference to AMTS operations and must accept any harmful interference 
from AMTS operation. Amateur stations within 80 km (50 miles) of an AMTS 
coast station must obtain written approval from the AMTS licensee prior 
to operating in the 219-220 MHz band. Amateur stations within 640 km 
(398 miles) of an AMTS coast station must notify the AMTS licensee in 
writing at least 30 days prior to initiation of operations in the 219-
220 MHz band. All amateur stations must notify the American Radio Relay 
League in writing at least 30 days prior to initiation of operations in 
the 219-220 MHz band (ARRL, 225 Main St., Newington, CT 06111-1494).
    (b) Subject to the requirements of Sec. 1.924 of this chapter, 
Sec. Sec. 80.215(h), and 80.475(a), each AMTS geographic area licensee 
may place stations anywhere within its region without obtaining prior 
Commission approval provided:
    (1) The AMTS geographic area licensee must locate its stations at 
least 120 kilometers from the stations of co-channel site-based AMTS 
licensees. Shorter separations between such stations will be considered 
by the Commission on a case-by-case basis upon submission of a technical 
analysis indicating that at least 18 dB protection will be provided to a 
site-based licensee's predicted 38 dBu signal level contour. The site-
based licensee's predicted 38 dBu signal level contour shall be 
calculated using the F(50, 50) field strength chart for Channels 7-13 in 
Sec. 73.699 (Fig. 10) of this chapter, with a 9 dB correction for 
antenna height differential. The 18 dB protection to the site-based 
licensee's predicted 38 dBu signal level contour shall be calculated 
using the F(50, 10) field strength chart for Channels 7-13 in Sec. 
73.699 (Fig. 10a) of this chapter, with a 9 dB correction factor for 
antenna height differential.
    (2) The locations and/or technical parameters of the transmitters 
are such that individual coordination of the channel assignment(s) with 
a foreign administration, under applicable international agreements and 
rules in this part, is not required.
    (3) For any construction or alteration that would exceed the 
requirements of Sec. 17.7 of this chapter, licensees must notify the 
appropriate Regional Office of the Federal Aviation Administration (FAA 
Form 7460-1) and file a request for antenna height clearance and 
obstruction marking and lighting specifications (FCC Form 854) with the 
FCC, Attn: Information Processing Branch, 1270 Fairfield Rd., 
Gettysburg, PA 17325-7245.
    (4) The transmitters must not have a significant environmental 
effect as defined by Sec. Sec. 1.1301 through 1.1319 of this chapter.
    (c) Any recovered frequency blocks will revert automatically to the 
holder of the geographic area license within which such frequencies are 
included. Any frequency blocks recovered where there is no geographic 
area licensee will be retained by the Commission for future licensing.
    (d) Automated multi-station system. Great Lakes Region. The 
following table describes the assignable carrier frequency pairs to 
provide communication services including automated calling, teleprinter 
and facsimile:

terms of power, and relates the power available at the receiver antenna 
terminals to transmitter power and antenna height and gain. It also sets 
forth the co-channel interference protection that VHF public coast 
station geographic area licensees must provide to incumbents and to 
other VHF public coast station geographic area licensees.

[64 FR 26887, May 18, 1999]



Sec. 80.753  Signal strength requirements at the service area contour.

    (a) The requirements for reception by a marine VHF shipboard 
receiver are satisfied if the field strength from the coast station, 
calculated in accordance with Sec. 80.771 is at least +17 dBu above one 
microvolt.
    (b) These field strengths, voltages and powers at the receiver input 
are equivalent:
    (1) -132 dBW (decibels referred to 1 watt).
    (2) 1.8 microvolts across 50 ohms.
    (3) +17 dBu (decibels referred to 1 microvolt per meter).
    (4) 7 microvolts per meter.



Sec. 80.755  Applicability.

    Applications for maritime frequencies in the 156-162 MHz band must 
include a map showing the proposed service area contour. The service 
area contour must be computed in accordance with the following 
procedures.



Sec. 80.757  Topographical data.

    (a) In the preparation of profile graphs and in determining the 
location and height above sea level of the antenna site, the elevations 
or contour intervals must be taken from U.S. Geological Survey 
topographic quadrangle maps, U.S. Army Corps of Engineers maps or 
Tennessee Valley Authority maps, whichever is the latest, for all areas 
for which maps are available. If such maps are not published for the 
area in question, the next best topographic information must be used. 
The maps used must include the principal area to be served. U.S. 
Geological Survey topographic quadrangle maps may be obtained from the 
Eastern Distribution Branch, U.S. Geological Survey, 1200 South Eads 
Street, Arlington, VA 22202, for maps of areas east of the Mississippi 
River, including Minnesota, Puerto Rico, and the Virgin Islands, and 
from the Western Distribution Branch, U.S. Geological Survey, Federal 
Center, Denver CO 80225, for maps of areas west of the Mississippi 
River, including Alaska, Hawaii, Louisiana, Guam and American Samoa. 
Sectional aeronautical charts are available from the Distribution 
Division, National Ocean Service, Riverdale, MD 20840.
    (b) In lieu of maps, the average terrain elevation may be computer 
generated, using elevations from a 30 second point or better topographic 
data file such as those available for the U.S. Geological Survey's 
National Geographic Information Center or the National Oceanic and 
Atmospheric Administration's National Geophysical Data Center. In case 
of dispute maps will be used to determine the correct value.



Sec. 80.759  Average terrain elevation.

    (a)(1) Draw radials from the antenna site for each 45 degrees of 
azimuth starting with true north. Any such radial which extends entirely 
over land from the antenna site to the point of +17 dBu field strength 
need not be drawn.
    (2) If the distance from the antenna site to the point of +17 dBu 
field strength between any of the 45 degrees radials would be less than 
the distances calculated along these radials, an additional radial 
between such adjacent

[[Page 127]]

radials must be plotted and calculations made in each case. Each 
additional radial must be that radial along which it appears by 
inspection that transmission loss would be greatest.
    (b) Draw a circle of 16 km (10 statute mile) radius using the 
antenna site as the center. Divide each radial into 320 meter (0.2 
statute mile) increments inside the circumference to the 3.2 km (2 
statute mile) point.
    (c) Calculate the height above sea level of each 320 meter (0.2 
statute mile) division by interpolating the contour intervals of the 
map, and record the value.
    (d) Average the values by adding them and dividing by the number of 
readings along each radial.
    (e) Calculate the height above average terrain by averaging the 
values calculated for each radial.

Sec. 80.761  Conversion graphs.

    The following graphs must be employed where conversion from one to 
the other of the indicated types of units is required.
    (a) Graph 1. To convert effective radiated power in watts to dBk or 
to dBW, find the power in watts on the horizontal axis. Move vertically 
along the line representing the power to the diagonal line. Move 
horizontally from the diagonal to the right side to read dBW and to the 
left to read dBk.
    (b) Graph 2. To convert microvolts across 50 ohms to received power 
in dBW, find the signal in microvolts on the horizontal axis. Move 
vertically to the diagonal line, then move right horizontally to read 
dBW.

[GRAPHIC] [TIFF OMITTED] TC02AP91.003

    (c) Graph 3. To convert received power in dBW to field intensity in 
dBu find the received power in dBW on the horizontal axis. Move 
vertically to the diagonal line, then move right horizontally to read 
dBu.

[[Page 130]]

[GRAPHIC] [TIFF OMITTED] TC02AP91.004



Sec. 80.763  Effective antenna height.

    The effective height of the antenna is the vertical distance between 
the center of the radiating system above the mean sea level and the 
average terrain elevation.

[[Page 131]]



Sec. 80.765  Effective radiated power.

    Effective radiated power is used in computing the service area 
contour. The effective radiated power is derived from the transmitter 
output power, loss in the transmission system including duplexers, 
cavities, circulators, switches and filters, and the gain relative to a 
half-wave dipole of the antenna system.



Sec. 80.767  Propagation curve.

    The propagation graph, Sec. 80.767 Graph 1, must be used in 
computing the service area contour. The graph provides data for field 
strengths in dBu for an effective radiated power of 1 kW, over sea 
water, fresh water or land (smooth earth); transmitting antena heights 
of 4,800, 3,200, 1,600, 800, 400, 200, and 100 feet; based on a 
receiving antenna height of 9 meters (30 feet), for the 156-162 MHz 
band. The use of this is described in this section.
    (a) Calculate the effective radiated power of the coast station, Ps 
in dB referred to 1 kW (dBk), as follows:
[GRAPHIC] [TIFF OMITTED] TC02AP91.005

where,
Pt=Transmitter output power in dB referred to 1 kW: Transmitter output 
power in watts is converted to dBk by Pt=10 [log10 (Power in watts)]-30. 
Also see Sec. 80.761 Graph 1 for a conversion graph.
G=Antenna gain in dB referred to a standard half-wave dipole, in the 
direction of each plotted radial, and
L=Line losses between the transmitter and the antenna, in dB.
    Notes: 1. To determine field strengths where the distance is known, 
for effective radiated powers other than 1kW (0 dBk): Enter the graph 
from the ``statute miles'' scale at the known distance, read up to 
intersection with the curve for the antenna height, read left to the 
``dBu for 1 kW radiated'' scale and note the referenced field strength 
(Fe). The value of the actual field strength (F) in dBu will be F=Fe+Ps 
where Ps is the effective radiated power calculated above.
    2. To determine distance, where the actual field strength is 
specified, for effective radiated powers other than 0 dBk: The value of 
the field referenced strength will be Fe=F-Ps in dBu. Enter the graph, 
from the ``dBu for 1 kW radiated'' scale at the corrected value of Fe, 
read right to intersection with the antenna height, read down to 
``statute miles'' scale.
    (b) Determine the antenna height. For antenna heights between the 
heights for which this graph is drawn, use linear interpolation; assume 
linear height-gain for antennas higher than 4,800 feet.
    (c) For receiver antenna heights lower than 9 meters (30 feet), 
assume that the field strength is the same as at 9 meters (30 feet).
    (d) Assume that propagation over fresh water or over land is the 
same as that over sea water.

[[Page 132]]

[GRAPHIC] [TIFF OMITTED] TC02AP91.006



Sec. 80.769  Shadow loss.

    Where the transmission path is obstructed the received signal must 
be adjusted to include shadow loss. Attenuation due to shadowing must be 
taken from Sec. 80.769 Graph 1, as follows:
    (a) Inspect the map(s) to determine if a hill(s) obstructs an 
imaginary line of

[[Page 133]]

sight (dashed line on illustrative profiles of Sec. 80.769 Graph 1 from 
the average terrain elevation at the coast station antenna to the water 
level at the ship location. If average terrain elevation exceeds the 
actual ground elevation at the antenna site, the latter elevation must 
be used as the average terrain elevation.
    (b) If a hill appears to obstruct the radio path, plot the antenna 
site elevation, the obstruction elevation and the height of the ship 
station on rectangular coordinate paper using elevation above mean sea 
level as the vertical scale and distance in statute miles as the 
horizontal scale. Then draw a straight line between the antenna and the 
ship.
    (c) If a hill obstructs the imaginary line of sight, determine its 
height (H) above the imaginary line and its distance (D) from either the 
coast or ship station, whichever is nearer, as illustrated by examples 
``A'' and ``B'' on Graph 1.
    (d) Read the shadow loss from this Graph 1 and subtract that loss 
from the computed received signal.
    (e) Where more than one hill obstructs the transmission path, 
determine the height and position of a single equivalent hill, as 
illustrated by example ``C'' on this graph. Read the shadow loss from 
this graph for the equivalent hill.

[[Page 134]]

[GRAPHIC] [TIFF OMITTED] TC02AP91.007



Sec. 80.771  Method of computing coverage.

    Compute the +17 dBu contour as follows:
    (a) Determine the effective antenna height above mean sea level 
according to the procedures in Sec. Sec. 80.757-80.761.
    (b) Determine the effective radiated power according to Sec. 
80,765. Determine

[[Page 135]]

for each radial the distance from the antenna site to the +17 dBu point 
of field strength using procedures of Sec. Sec. 80.765 and 80.767.
    (c) Plot on a suitable map each point of +17 dBu field strength for 
all radials and draw the contour by connecting the adjacent points by a 
smooth curve.



Sec. 80.773  Co-channel interference protection.

    (a) Where a VHF public coast station geographic area licensee shares 
a frequency with an incumbent VHF public coast station licensee, the 
ratio of desired to undesired signal strengths must be at least 12 dB 
within the service area of the station.
    (b) Where a VHF public coast station geographic area licensee shares 
a frequency with an incumbent private land mobile radio licensee, the 
VHF public coast station geographic area licensee must provide at least 
10 dB protection to the PLMR incumbent's predicted 38 dBu signal level 
contour. The PLMR incumbent's predicted 38 dBu signal level contour is 
calculated using the F(50, 50) field strength chart for Channels 7-13 in 
Sec. 73.699 (Fig. 10a) of this chapter, with a 9 dB correction factor 
for antenna height differential, and is based on the licensee's 
authorized effective radiated power and antenna height-above-average-
terrain.
    (c) VHF public coast station geographic area licensees are 
prohibited from exceeding a field strength of +5 dBu (decibels 
referenced to 1 microvolt per meter) at their service area boundaries, 
unless all the affected VHF public coast station geographic area 
licensees agree to the higher field strength.

Subpart T_Radiotelephone Installation Required for Vessels on the Great 
                                  Lakes



Sec. 80.951  Applicability.

    The Agreement Between the United States of America and Canada for 
Promotion of Safety on the Great Lakes by Means of Radio, 1973, applies 
to vessels of all countries when navigated on the Great Lakes. The Great 
Lakes Radio Agreement defines the Great Lakes as ``all waters of Lakes 
Ontario, Erie, Huron (including Georgian Bay), Michigan, Superior, their 
connecting and tributary waters and the River St. Lawrence as far east 
as the lower exit of the St. Lambert Lock at Montreal in the Province of 
Quebec, Canada,'' but does not include such of the connecting and 
tributary waters as may be specified in the Technical Regulations. The 
Technical Regulations do not include any connecting and tributary waters 
except the St. Mary's River, the St. Clair River, Lake St. Clair, the 
Detroit River and the Welland Canal. A vessel to which the Great Lakes 
Radio Agreement applies and which falls into the specific categories by 
paragraph (a), (b) or (c) of this section and not excepted by paragraph 
(d) or (e) of this section

[[Page 149]]

must comply with this subpart while navigated on the Great Lakes.
    (a) Every vessel 20 meters (65 feet) or over in length (measured 
from end to end over the deck, exclusive of sheer).
    (b) Every vessel engaged in towing another vessel or floating 
object, except:
    (1) Where the maximum length of the towing vessel, measured from end 
to end over the deck exclusive of sheer, is less than 8 meters (26 feet) 
and the length or breadth of the tow, exclusive of the towing line, is 
less than 20 meters (65 feet);
    (2) Where the vessel towed complies with this subpart;
    (3) Where the towing vessel and tow are located within a booming 
ground (an area in which logs are confined); or
    (4) Where the tow has been undertaken in an emergency and neither 
the towing vessel nor the tow can comply with this part.
    (c) Any vessel carrying more than six passengers for hire.
    (d) The requirements of the Great Lakes Radio Agreement do not apply 
to:
    (1) Ships of war and troop ships;
    (2) Vessels owned and operated by any national government and not 
engaged in trade.
    (e) The Commission may if it considers that the conditions of the 
voyage or voyages affecting safety (including but not necessarily 
limited to the regularity, frequency and nature of the voyages, or other 
circumstances) are such as to render full application of the Great Lakes 
Agreement unreasonable or unnecessary, exempt partially, conditionally 
or completely, any individual vessel for one or more voyages or for any 
period of time not exceeding one year.



Sec. 80.953  Inspection and certification.

    (a) Each U.S. flag vessel subject to the Great Lakes Agreement must

Lakes Agreement must be made by a technician holding one of the 
following: a General Radiotelephone Operator License, a GMDSS Radio 
Maintainer's License, a Second Class Radiotelegraph Operator's 
Certificate, or a First Class Radiotelegraph Operator's Certificate. 
Additionally, the technician must not be the vessel's owner, operator, 
master, or an employee of any of them. The results of the inspection 
must be recorded in the ship's radiotelephone log and include:
    (1) The date the inspection was conducted;
    (2) The date by which the next inspection needs to be completed;
    (3) The inspector's printed name, address, class of FCC license 
(including the serial number);
    (4) The results of the inspection, including any repairs made; and
    (5) The inspector's signed and dated certification that the vessel 
meets the requirements of the Great Lakes Agreement and the Bridge-to-
Bridge Act contained in subparts T and U of this part and has 
successfully passed the inspection.
    (c) The vessel owner, operator, or ship's master must certify that 
the inspection required by paragraph (b) was satisfactory.
    (d) The ship's log must be retained on-board the vessel for at least 
two years from the date of the inspection.

of the additional loads mentioned in paragraphs (d), (e) and (h) of this 
section for a period of at least:
    (1) One hour, on ships constructed on or after February 1, 1995;
    (2) One hour, on ships constructed before February 1, 1995, if the 
emergency source of electrical power complies fully with all relevant 
requirements of SOLAS, Chapter II-1, Regulation 42 or 43 (as amended); 
or
    (3) Six hours, on ships constructed before February 1, 1995, and on 
cargo ships of less than 500 tons gross tonnage, if the emergency source 
of electrical power is not provided or does not comply fully with all 
relevant requirements of SOLAS, Chapter II-1, Regulation 42 or 43 (as 
amended).
    (c) The reserve sources of energy need not supply independent HF and 
MF radio installations at the same time. The reserve sources of energy 
must be independent of the propelling power of the ship and the ship's 
electrical system.
    (d) Where, in addition to the VHF radio installation, two or more of 
the other radio installations, referred to in paragraph (b) of this 
section, can be connected to the reserve sources of energy, they must be 
capable of simultaneously supplying, for one hour, as specified in 
paragraph (b) of this section, the VHF radio installation and;
    (1) All other radio installations which can be connected to the 
reserve sources of energy at the same time; or
    (2) Whichever of the other radio installations will consume the most 
power, if only one of the other radio installations can be connected to 
the reserve sources of energy at the same time as the VHF radio 
installation.

       Operating Procedures for Distress and Safety Communications



Sec. 80.1109  Distress, urgency, and safety communications.

    (a) Distress traffic consists of all messages relating to the 
immediate assistance required by the ship in distress, including search 
and rescue communications and on-scene communications. Distress traffic 
must as far as possible be on the frequencies contained in Sec. 
80.1077.
    (b) Urgency and safety communications include: navigational and 
meteorological warnings and urgent information; ship-to-ship safety 
navigation communications; ship reporting communications; support 
communications for search and rescue operations; other urgency and 
safety messages and communications relating to the navigation, movements 
and needs of ships and weather observation messages destined for an 
official meteorological service.
    (c) Intership navigation safety communications are those VHF 
radiotelephone communications conducted between ships for the purpose of 
contributing to the safe movement of ships. The frequency 156.650 MHz is 
used for intership navigation safety communications (see Sec. 80.1077).



Sec. 80.1111  Distress alerting.

    (a) The transmission of a distress alert indicates that a mobile 
unit or person is in distress and requires immediate assistance. The 
distress alert is a digital selective call using a distress call format 
in bands used for terrestrial radio communication or a distress message 
format, which is relayed through space stations.
    (b) The distress alert must be sent through a satellite either with 
absolute priority in general communication channels or on exclusive 
distress and safety frequencies or, alternatively, on the distress and 
safety frequencies in the MF, HF, and VHF bands using digital selective 
calling.
    (c) The distress alert must be sent only on the authority of the 
person responsible for the ship, aircraft or other vehicle carrying the 
mobile station or the mobile earth station.
    (d) All stations which receive a distress alert transmitted by 
digital selective calling must immediately cease any transmission 
capable of interfering with distress traffic and must continue watch on 
the digital selective call distress calling channel until the call has 
been acknowledged to determine if a coast station acknowledges the call 
using digital selective calling. Additionally, the station receiving the 
distress alert must set watch on the associated distress traffic 
frequency for five minutes to determine if distress traffic takes place. 
The ship can acknowledge the call using voice or narrowband direct 
printing as appropriate on this channel to the ship or to the rescue 
authority.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46980, Aug. 7, 2003]



Sec. 80.1113  Transmission of a distress alert.

    (a) The distress alert must identify the station in distress and its 
position. The distress alert may also contain information regarding the 
nature of the distress, the type of assistance required, the course and 
speed of the mobile unit, the time that this information was recorded 
and any other information which might facilitate rescue.
    (b) The format of distress calls and distress messages must be in 
accordance with ITU-R Recommendation M.493-10, ``Digital Selective-
calling system for use in the Maritime Mobile Service,'' with Annexes 1 
and 2, 2000, as specified in Sec. 80.1101. ITU-R Recommendation M.493-
10 with Annexes 1 and 2 is incorporated by reference. The Director of 
the Federal Register approves this incorporation by reference in 
accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies of this 
standard can be inspected at the Federal Communications Commission, 445 
12th Street, SW., Washington, DC (Reference Information Center) or at 
the National Archives and Records Administration (NARA). For information 
on the availability of this material at NARA, call 202-741-6030, or go

regulations/ibr--locations.html. The ITU-R Recommendation can be 
purchased from the International Telecommunication Union (ITU), Place 
des Nations, CH-1211 Geneva 20, Switzerland.

[[Page 173]]

    (c) Ship-to-shore distress alerts are used to alert Rescue 
Coordination Centers via coast stations or coast earth stations that a 
ship is in distress. These alerts are based on the use of transmissions 
via satellites (from a ship earth station or a satellite EPIRB) and 
terrestrial services (from ship stations and EPIRBs).
    (d) Ship-to-ship distress alerts are used to alert other ships in 
the vicinity of the ship in distress and are based on the use of digital 
selective calling in the VHF and MF bands. The HF bands should not be 
used to notify ships in the vicinity unless no response is received 
within five minutes on VHF or MF.
    (e) Shore-to-ship distress alert relays are used by a station or 
Rescue Coordination Center to relay information about a ship in distress 
to, as appropriate, all ships, a selected group of ships, or a specific 
ship by satellite and/or terrestrial means. The distress alert relay 
must contain the identification of the mobile unit in distress, its 
position and all other information which might facilitate rescue.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46980, Aug. 7, 2003]



Sec. 80.1114  False distress alerts.

    The provisions of Sec. Sec. 80.334 and 80.335 apply to false 
distress alerts.

[68 FR 46980, Aug. 7, 2003]



Sec. 80.1115  Transmission of a distress alert by a station not itself in 
distress.

    (a) A station in the mobile or mobile-satellite service which learns 
that a mobile unit is in distress must initiate and transmit a distress 
alert relay in any of the following cases:
    (1) When the mobile unit in distress is not itself in a position to 
transmit the distress alert; or
    (2) When the master or person responsible for the mobile unit not in 
distress or the person responsible for the land station determines that 
further help is necessary.
    (b) A station transmitting a distress alert relay in accordance with 
paragraph (a) of this section or Sec. 80.1121(c) must indicate that it 
is not itself in distress.



Sec. 80.1117  Procedure for receipt and acknowledgement of distress alerts.

    (a) Normally, distress calls received using digital selective 
calling are only acknowledged using a DSC acknowledgement by a coast 
station. Ships should delay any acknowledgement in order to give 
sufficient time for a coast station to acknowledge the call. In cases 
where no acknowledgement has been heard and no distress traffic has been 
heard, the ship should transmit a distress alert relay to the coast 
station. Upon advice from the Rescue Coordination Center, the ship may 
transmit a DSC acknowledgement call to stop it from being repeated. 
Acknowledgement by digital selective calling of receipt of a distress 
alert in the terrestrial services must comply with ITU-R Recommendation 
M.541-8, ``Operational Procedures for the Use of Digital Selective-
Calling Equipment in the Maritime Mobile Service,'' with Annexes, 1997. 
ITU-R Recommendation M.541-8 with Annexes is incorporated by reference. 
The Director of the Federal Register approves this incorporation by 
reference in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies 
of this standard can be inspected at the Federal Communications 
Commission, 445 12th Street, SW., Washington, DC (Reference Information 
Center) or at the National Archives and Records Administration (NARA).

be purchased from the International Telecommunication Union (ITU), Place 
des Nations, CH-1211 Geneva 20, Switzerland.
    (b) Acknowledgement through a satellite of receipt of a distress 
alert from a ship earth station must be sent immediately (see Sec. 
80.1119).
    (c) Acknowledgement by radiotelephony of receipt of a distress alert 
from a ship station or a ship earth station must be given in the 
following form:
    (1) The distress signal MAYDAY;
    (2) The call sign or other identification of the station sending the 
distress message, spoken three times;

[[Page 174]]

    (3) The words THIS IS (or DE spoken as DELTA ECHO in case of 
language difficulties);
    (4) The call sign or other identification of the station 
acknowledging receipt, spoken three times;
    (5) The word RECEIVED (or RRR spoken as ROMEO ROMEO ROMEO in case of 
language difficulties);
    (6) The distress signal MAYDAY.
    (d) The acknowledgement by direct-printing telegraphy of receipt of 
a distress alert from a ship station must be given in the following 
form:
    (1) The distress signal MAYDAY;
    (2) The call sign or other identification of the station sending the 
distress alert;
    (3) The word DE;
    (4) The call sign or other identification of the station 
acknowledging receipt of the distress alert;
    (5) The signal RRR;
    (6) The distress signal MAYDAY.
    (e) The acknowledgement by direct-printing telegraphy of receipt of 
a distress alert from a ship earth station must be given by the coast 
earth station receiving the distress alert by retransmitting the ship 
station identity of the ship transmitting the distress alert.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46980, Aug. 7, 2003]



Sec. 80.1119  Receipt and acknowledgement of distress alerts by coast 
stations and coast earth stations.

    (a) Coast stations that receive a distress alert should defer 
acknowledgement for a short interval so that receipt may be acknowledged 
by a Rescue Coordination Center. Where an acknowledgement is not 
forthcoming within 3 minutes, the coast station in receipt of distress 
alerts must ensure that they are routed to a Rescue Coordination Center 
as soon as possible. Coast stations must provide assistance for distress 
communications when requested to do so by the U.S. Coast Guard. (This 
subpart does not specify any radio watches for coast stations.)
    (b) Coast earth stations in receipt of distress alerts must ensure 
that they are routed as soon as possible to a Rescue Coordination 
Center. Coast earth stations must relay, as soon as possible, an 
acknowledgement of a distress alert from a Rescue Coordination Center.
    (c) Certain messages must be carried without charge, regardless of 
the means by which they are transmitted:
    (1) Distress alert messages;
    (2) Search and rescue coordination messages;
    (3) Medical assistance messages where an imminent danger to life is 
present, or
    (4) Urgent meteorological or navigational danger messages passed in 
the ship-to-shore direction.



Sec. 80.1121  Receipt and acknowledgement of distress alerts by ship 
stations and ship earth stations.

    (a) Ship or ship earth stations that receive a distress alert must, 
as soon as possible, inform the master or person responsible for the 
ship of the contents of the distress alert.
    (b) For VHF and MF, ships in receipt of a distress alert shall not 
transmit a distress alert relay, but should listen on the distress 
traffic channel for 5 minutes and, if appropriate, acknowledge the alert 
by radiotelephony to the ship in distress and inform the coast station 
and/or Rescue Coordination Center. Distress alert relays to ``all 
ships'' on these bands may only be sent by a ship who has knowledge that 
another ship in distress is not itself able to transmit the distress 
alert, and the Master of the ship considers that further help is 
necessary.
    (c) For HF, ships in receipt of a distress alert shall listen on the 
distress traffic channel for 5 minutes. If no distress communications 
are heard and if the call is not acknowledged by a coast station, the 
ship shall transmit a distress relay on HF to the coast radio station 
and inform the Rescue Coordination Center. Distress alert relays to 
``all Ships'' on HF may only be sent by a ship who has knowledge that 
another ship in distress is not itself able to transmit the distress 
alert, and the Master of the ship considers that further help is 
necessary.
    (d) In cases where distress alert continues to be received from the 
same source, the ship may, after consultation with the Rescue 
Coordination Center, transmit a DSC acknowledgment to terminate the 
call.

[[Page 175]]

    (e) A ship station in receipt of a shore-to-ship distress alert 
relay (see Sec. 80.1113(e)) should establish communication as directed 
and render such assistance as required and appropriate.

Sec. 80.1123  Watch requirements for ship stations.

    (a) While at sea, all ships must maintain a continuous watch:
    (1) On VHF DSC channel 70, if the ship is fitted with a VHF radio 
installation in accordance with Sec. 80.1085(a)(2);
    (2) On the distress and safety DSC frequency 2187.5 kHz, if the ship 
is fitted with an MF radio installation in accordance with Sec. Sec. 
80.1089(a)(2) or 80.1091(a)(3);
    (3) On the distress and safety DSC frequencies 2187.5 kHz and 8414.5 
kHz also on at least one of the distress and safety DSC frequencies 
4207.5 kHz, 6312 kHz, 12577 kHz, or 16804.5 kHz appropriate to the time 
of day and the geographical position of the ship, if the ship is fitted 
with an MF/HF radio installation in accordance with Sec. Sec. 
80.1091(a)(2)(ii) or 80.1093(a) of this part (this watch may be kept by 
means of a scanning receiver limited to six distress and safety DSC 
frequencies); and
    (4) For satellite shore-to-ship distress alert, if the ship is 
fitted with an INMARSAT ship earth station in accordance with Sec. 
80.1091(a)(1).
    (b) While at sea, all ships must maintain radio watches for 
broadcasts of maritime safety information on the appropriate frequency 
or frequencies on which such information is broadcast for the area in 
which the ship is navigating.
    (c) Until February 1, 2005, every ship while at sea must maintain, 
when practicable, a continuous listening watch on VHF Channel 16. This 
watch must be kept at the position from which the ship is normally 
navigated or at a position which is continuously manned.
    (d) Every ship required to carry a radiotelephone watch receiver 
must maintain, while at sea, a continuous watch on the radiotelephone 
distress frequency 2182 kHz. This watch must be kept at the position 
from which the ship is normally navigated or at a position which is 
continually manned.
    (e) On receipt of a distress alert transmitted by use of digital 
selective calling techniques, ship stations must set watch on the 
radiotelephone distress and safety traffic frequency associated with the 
distress and safety calling frequency on which the distress alert was 
received.
    (f) Ship stations with narrow-band direct printing equipment must 
set watch on the narrow-band direct-printing frequency associated with 
the distress alert signal if it indicates that narrow-band direct-
printing is to be used for subsequent distress communications. If 
practicable, they should additionally set watch on the radiotelephone 
frequency associated with the distress alert frequency.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46981, Aug. 7, 2003]



Sec. 80.1125  Search and rescue coordinating communications.

    (a) The distress signal consists of the word MAYDAY, pronounced in 
radiotelephony as the French expression ``M'aider''. For distress 
traffic by radiotelephony, when establishing communications, calls must 
be prefixed by the distress signal MAYDAY.
    (b) Error correction techniques, in accordance with ITU-R 
Recommendation M.625-3, ``Direct-printing Telegraph Equipment Employing 
Automatic Identification in the Maritime Mobile Service,'' with Annex, 
1995, as specified in Sec. 80.1101, must be used for distress traffic 
by direct-printing telegraphy. All messages must be preceded by at least 
one carriage return, a line feed signal, a letter shift signal and the 
distress signal MAYDAY. ITU-R Recommendation M.625-3 with Annex is 
incorporated by reference. The Director of the Federal Register approves 
this incorporation by reference in accordance with 5 U.S.C. 552(a) and 1 
CFR Part 51. Copies of this standard can be inspected at the Federal 
Communications Commission, 445 12th Street, SW., Washington, DC 
(Reference Information Center) or at the National Archives and Records 
Administration (NARA). For information on the availability of this 
material at NARA, call

[[Page 176]]

202-741-6030, or go to: http://www.archives.gov/federal--register/code--
of--federal--regulations/ibr--locations.html. The ITU-R Recommendation 
can be purchased from the International Telecommunication Union (ITU), 
Place des Nations, CH-1211 Geneva 20, Switzerland.
    (c) Distress communications by direct-printing telegraphy should be 
in the ARQ mode when ships are communicating directly to the Coast Guard 
or other coast stations on channels which they normally guard. Other 
distress communications, including those on simplex channels provided 
for that purpose, should be in the broadcast forward error correction 
mode. The ARQ mode may subsequently be used when it is advantageous to 
do so.
    (d) The Rescue Coordination Center responsible for controlling a 
search and rescue operation will also coordinate the distress traffic 
relating to the incident or may appoint another station to do so.
    (e) The Rescue Coordination Center coordinating distress traffic, 
the unit coordinating search and rescue operations, or the coast station 
involved may impose silence on stations which interfere with that 
traffic. This instruction may be addressed to all stations or to one 
station only, according to circumstances. In either case, the following 
will be used:
    (1) In radiotelephony, the signal SEELONCE MAYDAY, pronounced as the 
French expression ``silence, m'aider'';
    (2) In narrow-band direct-printing telegraphy normally using 
forward-error correcting mode, the signal SILENCE MAYDAY. However, the 
ARQ mode may be used when it is advantageous to do so.
    (f) Until they receive the message indicating that normal working 
may be resumed (see paragraph (h) of this section), all stations which 
are aware of the distress traffic, and which are not taking part in it, 
and which are not in distress, are forbidden to transmit on the

    (f) When using frequency modulation or digital modulation for 
telemetry or telecommand in the 1435-1535 MHz or 2310-2390 MHz frequency 
bands with an authorized bandwidth greater than 1 MHz, the emissions 
must be attenuated as follows:
    (1) On any frequency removed from the assigned frequency by more 
than 50 percent of the authorized bandwidth plus 0.5 MHz up to and 
including 50 percent of the authorized bandwidth plus 1.0 MHz, the 
attenuation must be 60 dB, when measured in a 3.0 kHz bandwidth. The 
signal need not be attenuated more than 25 dB below 1 milliwatt.
    (2) On any frequency removed from the assigned frequency by more 
than 50 percent of the authorized bandwidth plus 1.0 MHz, the 
attenuation must be at least 55 + 10 log10 pY dB, when 
measured in a 3.0 kHz bandwidth.
    (g) The requirements of paragraphs (e) and (f) of this section apply 
to transmitters approved after January 1, 1977, and to all transmitters 
first installed after January 1, 1983.
    (h) For ELTs operating on 121.500 MHz, 243.000 MHz and 406.0-406.1 
MHz the mean power of any emission must be attenuated below the mean 
power of the transmitter (pY) as follows:
    (1) When the frequency is moved from the assigned frequency by more 
than 50 percent up to and including 100 percent of the authorized 
bandwidth the attenuation must be at least 25 dB;
    (2) When the frequency is removed from the assigned frequency by 
more than 100 percent of the authorized bandwidth the attenuation must 
be at least 30 dB.
    (i) In case of conflict with other provisions of Sec. 87.139, the 
provisions of this paragraph shall govern for aircraft earth stations. 
When using G1D, G1E, or G1W emissions in the 1646.5-1660.5 MHz frequency 
band, the emissions must be attenuated as shown below.
    (1) At rated output power, while transmitting a modulated single 
carrier, the composite spurious and noise output shall be attenuated by 
at least:

------------------------------------------------------------------------
              Frequency (MHz)                    Attenuation (dB)\1\

12000 to 18000............................  -70 dB/4 kHz
------------------------------------------------------------------------
\1\ These values are expressed in dB referenced to the carrier for the
  bandwidth indicated, and relative to the maximum emission envelope
  level, except where the attenuation is shown in dBW, the attenuation
  is expressed in terms of absolute power referenced to the bandwidth
  indicated.
\2\ Attenuation measured within the transmit band excludes the band
   35 kHz of the carrier frequency.
\3\ This level is not applicable for intermodulation products.
\4\ The upper limit for the excess power for any narrow-band spurious
  emission (excluding intermodulation products within a 30 kHz
  measurement bandwidth) shall be 10 dB above the power limit in this
  table.

    (2) The transmitter emission limit is a function of the modulation 
type and symbol rate (SR). Symbol Rate is expressed in symbols per 
second.
    (3) While transmitting a single modulated signal at the rated output 
power of the transmitter, the emissions must be attenuated below the 
maximum emission level by at least:

------------------------------------------------------------------------

Where:

SR = Symbol Rate,
SR = 1 x channel rate for BPSK,
SR = 0.5 x channel rate for QPSK.

    The mask shall be defined by drawing straight lines through the 
above points.
    (j) When using G7D for differential GPS in the 112-118 MHz band, the 
amount of power during transmission under all operating conditions when 
measured over a 25 kHz bandwidth centered on either of the second 
adjacent channels shall not exceed -25 dBm and shall decrease 5 dB per 
octave until -52 dBm.
    (k) For VHF aeronautical stations and aircraft stations operating 
with G1D or G7D emissions:
    (1) The amount of power measured across either first adjacent 25 kHz 
channel shall not exceed 2 dBm.
    (2) For stations first installed before January 1, 2002, the amount 
of power measured across either second adjacent channel shall be less 
than -25 dBm and the power measured in any other adjacent 25 kHz 
channels shall monotonically decrease at a rate of at least 5 dB per 
octave to a maximum value of -52 dBm. For stations first installed on or

kHz channel shall be less than -28 dBm;
    (ii) The amount of power measured across either fourth adjacent 25 
kHz channel shall be less than -38 dBm; and
    (iii) From thereon the power measured in any other adjacent 25 kHz 
channel shall monotonically decrease at a rate of at least 5 dB per 
octave to a maximum value of -53 dBm.
    (3) The amount of power measured over a 16 kHz channel bandwidth 
centered on the first adjacent 25 kHz channel shall not exceed -18 dBm.

Sec. 87.141  Modulation requirements.

    (a) When A3E emission is used, the modulation percentage must not 
exceed 100 percent. This requirement does not apply to emergency locator 
transmitters or survival craft transmitters.
    (b) A double sideband full carrier amplitude modulated 
radiotelephone transmitter with rated carrier power output exceeding 10 
watts must be capable of automatically preventing modulation in excess 
of 100 percent.
    (c) If any licensed radiotelephone transmitter causes harmful 
interference to any authorized radio service because of excessive 
modulation, the Commission will require the use of the transmitter to be 
discontinued until it is rendered capable of automatically preventing 
modulation in excess of 100 percent.
    (d) Single sideband transmitters must be able to operate in the 
following modes:

------------------------------------------------------------------------
                                        Level N(dB) of the carrier with
             Carrier mode                respect to peak envelope power

                                       Aeronautical stations N<-40.
------------------------------------------------------------------------


[[Page 201]]

    (e) Each frequency modulated transmitter operating in the band 72.0-
76.0 MHz must have a modulation limiter.
    (f) Each frequency modulated transmitter equipped with a modulation 
limiter must have a low pass filter between the modulation limiter and 
the modulated stage. At audio frequencies between 3 kHz and 15 kHz, the 
filter must have an attenuation greater than the attenuation at 1 kHz by 
at least 40 log10 (f/3) db where ``f'' is the frequency in 
kilohertz. Above 15 kHz, the attenuation must be at least 28 db greater 
than the attenuation at 1 kHz.
    (g) Except that symmetric side bands are not required, the 
modulation characteristics for ELTs must be in accordance with 
specifications contained in the Federal Aviation Administration (FAA) 
Technical Standard Order (TSO) Document TSO-C91a titled ``Emergency 
Locator Transmitter (ELT) Equipment'' dated April 29, 1985. TSO-C91a is 
incorporated by reference in accordance with 5 U.S.C. 552(a). TSO-C91a 
may be obtained from the Department of Transportation, Federal Aviation 
Administration, Office of Airworthiness, 800 Independence Avenue SW., 
Washington DC 20591.
    (h) ELTs must use A3X emission and may use A3E or NON emissions on 
an optional basis while transmitting. Each transmission of a synthesized 
or recorded voice message from an ELT must be preceded by the words 
``this is a recording''; transmission of A3E or NON emission must not 
exceed 90 seconds; and any transmission of A3E or NON emissions must be 
followed by at least three minutes of A3X emission.
    (i) ELTs manufactured on or after October 1, 1988, must have a 
clearly defined carrier frequency distinct from the modulation sidebands 
for the mandatory emission, A3X, and, if used, the A3E or NON emissions. 
On 121.500 MHz at least thirty per cent of the total power emitted 
during any transmission cycle with or without modulation must be 
contained within plus or minus 30 Hz of the carrier frequency. On 
243.000 MHz at least thirty percent of the total power emitted during 
any transmission cycle with or without modulation must be contained 
within plus or minus 60 Hz of the carrier frequency. Additionally, if 
the type of emission is changed during transmission, the carrier 
frequency must not shift more than plus or minus 30 Hz on 121.500 MHz 
and not more than plus or minus 60Hz on 243.000 MHz. The long term 
stability of the carrier frequency must comply with the requirements in 
Sec. 87.133 of this part.
    (j) Transmitters used at Aircraft earth stations must employ BPSK 
for transmission rates up to and including 2400 bits per second, and 
QPSK for higher rates.

FR 11518, Mar. 19, 1991; 57 FR 45749, Oct. 5, 1992]



Sec. 87.143  Transmitter control requirements.

    (a) Each transmitter must be installed so that it is not accessible 
to, or capable of being operated by persons other than those authorized 
by the licensee.
    (b) Each station must be provided with a control point at the 
location of the transmitting equipment, unless otherwise specifically 
authorized. Except for aeronautical enroute stations governed by 
paragraph (e) of this section, a control point is the location at which 
the radio operator is stationed. It is the position at which the 
transmitter(s) can immediately be turned off.
    (c) Applicants for additional control points at aeronautical 
advisory (unicom) stations must specify the location of each proposed 
control point.
    (d) Except for aeronautical enroute stations governed by paragraph 
(f) of this section, the control point must have the following 
facilities installed:
    (1) A device that indicates when the transmitter is radiating or 
when the transmitter control circuits have been switched on. This 
requirement does not apply to aircraft stations;
    (2) Aurally monitoring of all transmissions originating at dispatch 
points;
    (3) A way to disconnect dispatch points from the transmitter; and
    (4) A way to turn off the transmitter.
    (e) A dispatch point is an operating position subordinate to the 
control point. Dispatch points may be installed without authorization 
from the Commission, and dispatch point operators are not required to be 
licensed.

[[Page 202]]

    (f) In the aeronautical enroute service, the control point for an 
automatically controlled enroute station is the computer facility which 
controls the transmitter. Any computer controlled transmitter must be 
equipped to automatically shut down after 3 minutes of continuous 
transmission of an unmodulated carrier.



Sec. 87.145  Acceptability of transmitters for licensing.

    (a) Each transmitter must be certificated for use in these services, 
except as listed in paragraph (c) of this section. However, aircraft 
stations which transmit on maritime mobile frequencies must use 
transmitters certificated for use in ship stations in accordance with 
part 80 of this chapter. Certification under part 80 is not required for 
aircraft earth stations transmitting on maritime mobile-satellite 
frequencies. Such stations must be certificated under part 87.
    (b) Some radio equipment installed on air carrier aircraft must meet 
the requirements of the Commission and the requirements of the FAA. The 
FAA requirements may be obtained from the FAA, Aircraft Maintenance 
Division, 800 Independence Ave., SW., Washington, DC 20591.
    (c) The equipment listed below is exempted from certification. The 
operation of transmitters which have not been certificated must not 
result in harmful interference due to the failure of those transmitters 
to comply with technical standards of this subpart.
    (1) Flight test station transmitters for limited periods where 
justified.
    (2) U.S. Government transmitters furnished in the performance of a 
U.S. Government contract if the use of certificated equipment would 
increase the cost of the contract or if the transmitter will be 
incorporated in the finished product. However, such equipment must meet 
the technical standards contained in this subpart.
    (3) ELTs verified in accordance with Sec. 87.147(e).
    (4) Signal generators when used as radionavigation land test 
stations (MTF).
    (d) Aircraft earth stations must correct their transmit frequencies 
for Doppler effect relative to the satellite. The transmitted signal may 
not deviate more than 335 Hz from the desired transmit frequency. (This 
is a root sum square error which assumes zero error for the received 
ground earth station signal and includes the AES transmit/receive 
frequency reference error and the AES automatic frequency control 
residual errors.) The applicant must attest that the equipment provides 
adequate Doppler effect compensation and where applicable, that 
measurements have been made that demonstrate compliance. Submission of 
data demonstrating compliance is not required unless requested by the 
Commission.

[63 FR 36607, July 7, 1998, as amended at 69 FR 32881, June 14, 2004]



Sec. 87.147  Authorization of equipment.

    (a) Certification may be requested by following the procedures in 
part 2 of this chapter. Aircraft transmitters must meet the requirements 
over an ambient temperature range of -20 degrees to +50 degrees Celsius.
    (b) ELTs manufactured after October 1, 1988, must meet the output 
power characteristics contained in Sec. 87.141(i) when tested in 
accordance with the Signal Enhancement Test contained in subpart N, part 
2 of this chapter. A report of the measurements must be submitted with 
each application for certification. ELTs that meet the output power 
characteristics of the section must have a permanent label prominently 
displayed on the outer casing state, ``Meets FCC Rule for improved 
satellite detection.'' This label, however, must not be placed on the 
equipment without authorization to do so by the Commission. Application 
for such authorization may be made either by submission of a new 
application for certification accompanied by the required fee and all 
information and test data required by parts 2 and 87 of this chapter or, 
for ELTs approved prior to October 1, 1988, a letter requesting such 
authorization, including appropriate test data and a showing that all 
units produced under the original equipment authorization comply with 
the requirements of this paragraph without change to the original 
circuitry.
    (c) An applicant for a station license may request certification for 
an individual transmitter by following the

[[Page 203]]

procedure in part 2 of this chapter. Such a transmitter will be 
individually certified and so noted on the station license.
    (d) An applicant for certification of equipment intended for 
transmission in any of the frequency bands listed in paragraph (d)(3) of 
this section must notify the FAA of the filing of a certification 
application. The letter of notification must be mailed to: FAA, Office 
of Spectrum Policy and Management, ASR-1, 800 Independence Ave., SW., 
Washington, DC 20591 prior to the filing of the application with the 
Commission.
    (1) The notification must describe the equipment, give the 
manufacturer's identification, antenna characteristics, rated output 
power, emission type and characteristics, the frequency or frequencies 
of operation, and essential receiver characteristics if protection is 
required.
    (2) The certification application must include a copy of the 
notification letter to the FAA. The Commission will not act until it 
receives the FAA's determination regarding whether it objects to the 
application for equipment authorization. The FAA should mail its 
determination to: Office of Engineering and Technology Laboratory, 
Authorization and Evaluation Division, 7435 Oakland Mills Rd., Columbia, 
MD 21046. The Commission will consider the FAA determination before 
taking final action on the application.
    (3) The frequency bands are as follows:

90-110 kHz
190-285 kHz
325-435 kHz
74.800 MHz to 75.200 MHz
108.000 MHz to 137.000 MHz

31.800 GHz to 33.400 GHz

    (e) Verification reports for ELTs capable of operating on the 
frequency 406.0-406.1 MHz must include sufficient documentation to show 
that the ELT meets the requirements of Sec. 87.199(a). A letter 
notifying the FAA of the ELT verification must be mailed to: FAA, Office 
of Spectrum Policy and Management, ASR-1, 800 Independence Avenue SW., 
Washington, DC 20591.
    (f) Certification may be requested for equipment that has the 
capability to transmit in the 138-144 MHz, 148-149.9 MHz, or 150.5-150.8 
MHz bands as well as frequency bands set forth in Sec. 87.173. The 
Commission will only certify this equipment for use in the bands 
regulated by this part.

messages include those lost by the VHF data receiver system or which do 
not pass the cyclic redundancy check (CRC) after application of the 
forward error correction (FEC).
    (b) The aircraft receiving antenna can be horizontally or vertically 
polarized. Due to the difference in the signal strength of horizontally 
and vertically polarized components of the broadcast signal, the total 
aircraft implementation loss is limited to 15 dB for horizontally 
polarized receiving antennas and 11 dB for vertically polarized 
receiving antennas.

    (d) Intermodulation Immunity. The receiver shall meet the 
requirements specified in paragraph (a) of this section in the presence 
of interference from two-signal, third order intermodulation products of 
two VHF-FM broadcast signals having levels in accordance with the 
following:
    (1) 2N1 + N2 + 72 <= 0 for VHF-FM sound 
broadcasting signals in the range 107.7-108 MHz; and
    (2) 2N1 + N2 + 3 (24 -20log delta f/0.4) <= 0 
for VHF-FM sound broadcasting signals below 107.7 MHz, where the 
frequencies of the two VHF-FM sound broadcasting signals produce, within 
the receiver, a two signal, third-order intermodulation product on the 
desired VDB frequency.
    (3) In the formulas in paragraphs (d)(1) and (d)(2) of this section, 
N1 and N2 are the levels (dBm) of the two VHF FM 
sound broadcasting signals at the VHF data broadcast (VDB) receiver

Sec. 87.169  Scope.

    This subpart contains class of station symbols and a frequency table 
which lists assignable frequencies. Frequencies in the Aviation Services 
will transmit communications for the safe, expeditious, and economic 
operation of aircraft and the protection of life and property in the 
air. Each class of land station may communicate in accordance with the 
particular sections of this part which govern these classes. Land 
stations in the Aviation Services in Alaska may transmit messages 
concerning sickness, death, weather, ice conditions or other matters 
relating to safety of life and property if there is no other established 
means of communications between the points in question and no charge is 
made for the communications service.

Sec. 87.185  Scope of service.

    (a) Aircraft stations must limit their communications to the 
necessities of safe, efficient, and economic operation of aircraft and 
the protection of life and property in the air, except as otherwise 
specifically provided in this part. Contact with an aeronautical land 
station must only be attempted when the aircraft is within the serivce 
area of the land station. however, aircraft stations may transmit 
advisory information on air traffic control, unicom or aeronautical 
multicom frequencies for the benefit and use of other stations 
monitoring these frequencies in accordance with FAA recommended traffic 
advisory practices.
    (b) Aircraft public correspondence service must be made available to 
all persons without discrimination and on reasonable demand, and must 
communicate without discrimination with any public coast station or 
mobile-satellite earth station authorized to provide aircraft public 
correspondence service.
    (c) Aircraft public correspondence service on maritime mobile 
frequencies may only be carried by aircraft stations licensed to use 
maritime mobile frequencies and must follow the rules for public 
correspondence in part 80.
    (d) Aircraft public correspondence service on Aeronautical Mobile-
Satellite (R) Service frequencies may only be carried on aircraft earth 
stations licensed to use Aeronautical Mobile-Satellite (R) frequencies 
and are subject to the rules for public correspondence in this part. 
Aircraft public correspondence service on Maritime Mobile-Satellite 
Service frequencies may only be carried by aircraft earth stations 
licensed to use Maritime Mobile-Satellite frequencies and are subject to 
the rules for public correspondence in part 80.

[53 FR 28940, Aug. 1, 1988, as amended at 55 FR 30464, July 26, 1990]



Sec. 87.215  Supplemental eligibility.

    (a) A unicom and any associated dispatch or control points must be 
located on the airport to be served.
    (b) Only one unicom will be authorized to operate at an airport 
which does not have a control tower, RCO or FAA flight service station. 
At an airport which has a part-time or full-time control tower, RCO or 
FAA flight service station, the one unicom limitation does not apply and 
the airport operator and all aviation services organizations may be 
licensed to operate a unicom on the assigned frequency.
    (c) At an airport where only one unicom may be licensed, eligibility 
for new unicom licenses is restricted to State or local government 
entities, and to nongovernmental organizations (NGOs) that are 
authorized to apply for the license by a State or local government 
entity whose primary mission is the provision of public safety services. 
All applications submitted by NGOs must be accompanied by a new, written 
certification of support (for the NGO applicant to operate the applied 
for station) by the state or local government entity. Applications for a 
unicom license at the same airport, where only one unicom may be 
licensed, that are filed by two or more applicants meeting these 
eligibility criteria must be

[[Page 217]]

resolved through settlement or technical amendment.
    (d) At an airport where only one unicom may be licensed, the license 
may be assigned or transferred only to an entity meeting the 
requirements of paragraph (c) of this section.
    (e) An applicant for renewal of a unicom license shall be granted a 
presumptive renewal expectancy regardless of whether the applicant is 
eligible for a new unicom license under paragraph (c) of this section. 
Unless the renewal expectancy is defeated, applications that are 
mutually exclusive with the renewal application will not be accepted. 
The renewal expectancy may be defeated only upon a determination, 
following a hearing duly designated on the basis of a petition to deny 
or on the Commission's own motion, that the renewal applicant has not 
provided substantial service. For purposes of this paragraph, 
substantial service means service which is sound, favorable, and 
substantially above a level of mediocre service during the applicant's 
past license term. If the renewal expectancy is defeated, the renewal 
application will be dismissed unless the renewal applicant is eligible 
for a new unicom license pursuant to paragraph (c) of this section.
    (f) At an airport where only one unicom may be licensed, when the 
Commission believes that the unicom has been abandoned or has ceased 
operation, another unicom may be licensed on an interim basis pending 
final determination of the status of the original unicom. An applicant 
for an interim license must notify the present licensee and must comply 
with the notice requirements of paragraph (d) of this section.
    (g) An applicant for a unicom license, renewal or modification of 
frequency assignment at an airport which does not have a control tower, 
RCO or FAA flight service station must notify in writing the owner of 
the airport and all aviation service organizations located at the 
airport. The notice must include the applicant's name and address, the 
name of the airport and a statement that the applicant intends to file 
an application with the Commission for a unicom. The notice must be 
given within the ten days preceding the filing of the application with 
the Commission. Each applicant must certify upon application that either 
notice has been given and include the date of notification, or notice is 
not required because the applicant owns the airport and there are no 
organizations that should be notified.

FR 67696, Dec. 22, 1993; 69 FR 32885, June 14, 2004]



Sec. 87.219  Automatic operations.

    (a) A station operator need not be present when an automated unicom 
is in operation.
    (b) Unicoms operating in an automated mode must comply with the 
requirements of paragraphs (1)-(5) of this section, in addition to the 
requirements applicable to non-automated unicom operations.
    (1) An automated unicom must transmit only in response to 
interrogating signals from aircraft, including but not limited to the 
brief keyed RF signals specified in Sec. 87.187(y).
    (2) An automated unicom must monitor the unicom frequency prior to 
transmission, and provide a brief delay between the aircraft's 
interrogating signal and the automatic unicom's response.
    (3) Automated advisory transmissions must be as brief as possible, 
and must never exceed one minute in length.

[[Page 218]]

    (4) An automated unicom may not provide weather information at an 
airport that has an operational, FAA-certified, automatic weather 
facility, unless the unicom itself is certified by the FAA.
    (5) If weather information is provided by an automated unicom:
    (i) weather sensors must be placed in order to adequately represent 
the weather conditions at the airport(s) to be served;
    (ii) the weather information must be proceeded by the word 
``advisory;''
    (iii) the phrase ``automated advisory'' must be included when the 
weather information was gathered by real-time sensors or within the last 
minute; and,
    (iv) the time and date of the last update must be included when the 
weather information was not gathered within the last minute.
    (c) Only one automated unicom may be operated at an uncontrolled 
airport. Prior to the operation of an automated unicom at an airport 
with more than one unicom licensee, all of the licensees at that airport 
must sign a letter of agreement stating which licensee(s) control the 
automated unicom operations, and, if control is to be shared among 
several operators, how that control will be divided or scheduled. The 
original or a copy of the letter of agreement must be kept with each 
licensees' station records. Within 90 days of the date upon which a new 
unicom operator is licensed at an airport where more than one unicom is 
authorized, and an automated unicom is being operated, an amended letter 
of agreement that includes the new licensee's signature must be signed 
or automated unicom operations must cease.

                Subpart H_Aeronautical Multicom Stations



Sec. 87.237  Scope of service.

    (a) The communications of an aeronautical multicom station 
(multicom) must pertain to activities of a temporary, seasonal or 
emergency nature involving aircraft in flight. Communications are 
limited to directing or coordinating ground activities from the air or 
aerial activities from the ground. Air-to-air communications will be 
authorized if the communications are directly connected with the air-to-
ground or ground-to-air activities described above. Multicom 
communications must not include those air/ground communications provided 
for elsewhere in this part.
    (b) If there is not unicom and an applicant is unable to meet the 
requirements for a unicom license, the applicant will be eligible for a 
multicom license.
    (1) The multicom license becomes invalid when a unicom is 
established at the landing area.
    (2) Multicoms must not be used for ATC purposes other than the relay 
of ATC information between the pilot and air traffic controller. 
Relaying of ATC information is limited to the following:
    (i) Revisions of proposed departure time;
    (ii) Takeoff, arrival flight plan cancellation time;
    (iii) ATC clearances, provided a letter of agreement is obtained 
from the FAA by the licensee of the multicom.
    (3) Communications by a multicom must be limited to the safe and 
expeditious operation of private aircraft, pertaining to the conditions 
of runways, types of fuel available, wind conditions, weather 
information, dispatching or other information. On a secondary basis, 
multicoms may transmit communictions which pertain to efficient portal-
to-portal transit of an aircraft such as requests for ground 
transportation, food or lodging.



Sec. 87.239  Supplemental eligibility.

    Each applicant for a multicom may be required to demonstrate why 
such a station is necessary, based on the scope of service defined 
above.

     Subpart I_Aeronautical Enroute and Aeronautical Fixed Stations

                      Aeronautical Enroute Stations



Sec. 87.261  Scope of service.

    (a) Aeronautical enroute stations provide operational control 
communications to aircraft along domestic or international air routes. 
Operational control communications include the safe, efficient and 
economical operation of aircraft, such as fuel, weather, position 
reports, aircraft performance, and essential services and supplies. 
Public correspondence is prohibited.
    (b) Service must be provided to any aircraft station licensee who 
makes cooperative arrangements for the operation, maintenance and 
liability of the stations which are to furnish enroute service. In 
emergency or distress situations service must be provided without prior 
arrangements.
    (c) Except in Alaska, only one aeronautical enroute station licensee 
will be authorized at any one location. In Alaska, only one aeronautical 
enroute station licensee in the domestic service and one aeronautical 
enroute station licensee in the international service will be authorized 
at any one location. (Because enroute stations may provide service over 
a large area containing a number of air routes or only provide 
communications in the local area of an airport, location here means the 
area which can be adequately served by the particular station.)
    (d) In Alaska, only stations which serve scheduled air carriers will 
be licensed to operate aeronautical enroute stations. Applicants must 
show that the station will provide communications only along routes 
served by scheduled air carriers.
    (e) Mobile units may be operated under an aeronautical enroute 
station authorization so long as the units are limited to use at an 
airport and are only used to communicate with aircraft on the ground or 
the associated aeronautical enroute station. Mobile units are further 
limited to operation on the VHF frequencies listed in 87.263(a)(1).
    (f) Mobile units licensed under paragraph (e) of this section shall 
not be operated on air traffic control frequencies, nor cause harmful 
interference to, communications on air traffic control frequencies.

                   Subpart N_Emergency Communications



Sec. 87.393  Scope of service.

    This subpart provides the rules governing operation of stations in 
the Aviation Services during any national or local emergency situation 
constituting a threat to national security or safety of life and 
property. This subpart is consistent with the Aeronautical Emergency 
Communications System Plan for all Aviation Services licensees of the 
Commission which was developed pursuant to sections 1, 4(o), 301 and 303 
of the Communications Act, and Executive Order 11490, as amended. This 
Plan provides for emergency communications to meet the requirements of 
the Plan for the Security Control of Air Traffic and Air Navigation Aids 
(SCATANA), Civil Reserve Air Fleet (CRAF), War Air Service Program 
(WASP) and, where applicable, State and Regional Disaster Airlift 
Planning (SARDA).



Sec. 87.395  Plan for the Security Control of Air Traffic and Air 
Navigation Aids (Short Title: SCATANA).

    (a) The Plan for the Security Control of Air Traffic and Air 
Navigation Aids (SCATANA) is promulgated in furtherance of the Federal 
Aviation Act of 1958, as amended, the Communications Act and Executive 
Order 11490, as amended. SCATANA defines the responsibilities of the 
Commission for the security control of non-Federal air navigation aids.
    (b) Under the responsibilities defined in SCATANA, an FCC Support 
Plan for the Security Control of Non-Federal Air Navigation Aids has 
been developed by the Commission. The FCC Support Plan defines 
responsibilities, procedures, and instructions in consonance with 
SCATANA which will effect control of non-Federal air navigation aids 
when SCATANA is implemented. It permits the use of such navigation aids 
by aircraft of military and civil agencies when SCATANA is implemented. 
The FCC Support Plan highlights those parts of SCATANA which deal 
specifically with non-Federal air navigation aids. SCATANA and the FCC 
Support Plan apply to radionavigation stations authorized by the 
Commission in the following manner:
    (1) All licensees are subject to restrictions imposed by appropriate 
military authorities pursuant to SCATANA and the FCC Support Plan when 
an Air Defense Emergency or Defense Emergency exists or is imminent. The 
restrictions will be imposed through FAA Air Route Traffic Control 
Centers (ARTCCs).
    (2) All licensees of aeronautical radionavigation (VOR/DME, ILS, 
MLS, LF and MF non-directional beacons) stations will comply with 
SCATANA implementation instructions from FAA ARTCCs as follows:
    (i) Shut down the above navigation aids as directed. These 
instructions will permit time to land or disperse airborne aircraft, and 
will permit extension of time when the air traffic situation dictates.
    (ii) Shut down as soon as possible stations which require more than 
five minutes control time, unless directed otherwise or unless such 
stations are essential for the handling of existing air traffic.
    (iii) Operate aeronautical radionavigation stations to ensure that 
required stations, as indicated in flight plans, will be available for 
authorized aircraft flights.
    (3) Licensees of aeronautical radionavigation stations will be 
notified of the reduction or removal of SCATANA restrictions by FAA 
ARTCCs when notice of the termination is issued.
    (4) Licensees of aeronautical radionavigation stations may 
voluntarily participate in SCATANA tests as requested by an ARTCC. 
SCATANA testing must not interrupt the normal service of non-Federal air 
navigation aids.



Sec. 87.397  Emergency operations.

    (a) The licensee of any land station in the Aviation services, 
during a local emergency involving the safety of life

[[Page 228]]

and property may communicate in a manner other than that specified in 
the license (See Sec. 87.395). Such emergency operations may include 
operation at other locations or with equipment not specified in the 
license or by unlicensed personnel provided that:
    (1) Such operations are under the control and supervision of the 
station licensee,
    (2) The emergency use is discontinued as soon as practicable upon 
termination of the emergency,
    (3) In no event shall any station transmit on frequencies other than 
or with power in excess of that specified in the license,
    (4) The details of the emergency must be retained with the station 
license, and
    (5) At a controlled airport these communications must be coordinated 
with the FAA.
    (b) The unicom frequencies listed in subpart G may also be used for 
communications with private aircraft engaged in organized civil defense 
activities in preparation for, during an enemy attack or immediately 
after an enemy attack. When used for these purposes, unicoms may be 
moved from place to place or operated at unspecified locations, except 
at landing areas served by other unicoms or control towers.
    (c) In any case in which a license for unattended operation has been 
granted, the Commission may at any time, for national defense, modify 
the license.



                Subpart O_Airport Control Tower Stations



Sec. 87.417  Scope of service.

    (a) Airport control tower stations (control towers) and control 
tower remote communications outlet stations (RCOs) must limit their 
communications to the necessities of safe and expeditious operations of 
aircraft operating on or in the vicinity of the airport. Control towers 
and RCOs provide air traffic control services to aircraft landing, 
taking off and taxing on the airport as well as aircraft transiting the 
airport traffic area. Additionally, control towers and RCOs can provide 
air traffic control services to vehicles operating on airport movement 
areas (see subpart L of this part). Control towers and RCOs must serve 
all aircraft without discrimination. An RCO must be remotely operated 
from a control tower or other FAA control facility located at a nearby 
airport.
    (b) A control tower must maintain a continuous watch on the 
following frequencies during the hours of operation:

121.500 MHz
3023.0 kHz (Alaska only)
5680.0 kHz (Alaska only)

    The Commission may exempt from these watch requirements the licensee 
of an airport control tower station if a satisfactory showing has been 
made that such an exemption will not adversely affect life and property 
in the air.

Sec. 87.477  Condition of grant for radionavigation land stations.

    Radionavigation land stations may be designated by the FAA as part 
of the National Airspace System. Stations so designated will be required 
to serve the public under IFT conditions. This condition of grant is 
applicable to all radionavigation land stations.



Sec. 87.479  Harmful interference to radionavigation land stations.

    (a) Military or other Government stations have been authorized to 
establish wide-band systems using frequency-hopping spread spectrum 
techniques in the 960-1215 MHz band. Authorization for a Joint Tactical 
Information Distribution Systems (JTIDS) has been permitted on the basis 
of non-interference to the established aeronautical radionavigation 
service in this band. In order to accommodate the requirements for the 
system within the band, restrictions are imposed. Transmissions will be 
automatically prevented if:
    (1) The frequency-hopping mode fails to distribute the JTIDS 
spectrum uniformly across the band;
    (2) The radiated pulse varies from the specified width of 6.4 
microseconds 5%;
    (3) The energy radiated within 7 MHz of 1030 
and 1090 MHz exceeds a

[[Page 234]]

level of 60 dB below the peak of the JTIDS spectrum as measured in a 300 
kHz bandwidth. The JTIDS will be prohibited from transmitting if the 
time slot duty factor exceeds a 20 percent duty factor for any single 
user and a 40 percent composite duty factor for all JTIDS emitters in a 
geographic area.
    (b) If radionavigation systems operating in the 960-1215 MHz band 
experience interference or unexplained loss of equipment performance, 
the situation must be reported immediately to the nearest office of the 
FAA, the National Telecommunications and Information Administration, 
Washington, DC 20504, or the nearest Federal Communications Commission 
field office. The following information must be provided to the extent 
available:
    (1) Name, call sign and category of station experiencing the 
interference;
    (2) Date and time of occurrence;
    (3) Geographical location at time of occurrence;
    (4) Frequency interfered with;
    (5) Nature of interference; and
    (6) Other particulars.



Sec. 87.481  Unattended operation of domestic radiobeacon stations.

    (a) Radiobeacons may be licensed for unattended operation. An 
applicant must comply with the following:
    (1) The transmitter is crystal controlled and specifically designed 
for radiobeacon service and capable of transmitting by self-actuating 
means;
    (2) The emissions of the transmitter must be continuously monitored 
by a licensed operator, or by a direct positive automatic monitor, 
supplemented by aural monitoring at suitable intervals;
    (3) If as a result of aural monitoring it is determined that a 
deviation from the terms of the station license has occurred, the 
transmitters must be disabled immediately by a properly authorized 
person. If automatic monitoring is used, the monitor must insure that 
the operation of the transmitter meets the license terms or is disabled;
    (4) A properly authorized person must be able to reach the 
transmitter and disable it in a reasonable amount of time, so as not to 
adversely affect life or property in the air;
    (5) The equipment must be inspected at least every 180 days. Results 
of inspections must be kept in the station maintenance records;
    (6) The transmitter is not operable by or accessible to, other than 
authorized persons;
    (7) The transmitter is in a remote location.
    (b) Authority for unattended operation must be expressly stated in 
the station license.
