causing a conventional spreading of the RF energy about the frequency 
carrier. The frequency of the carrier is not fixed but changes at fixed 
intervals under the direction of a coded sequence. The wide RF bandwidth 
needed by such a system is not required by spreading of the RF energy 
about the carrier but rather to accommodate the range of frequencies to 
which the carrier frequency can hop. The test of a frequency hopping 
system is that the near term distribution of hops appears random, the 
long term distribution appears evenly distributed over the hop set, and 
sequential hops are randomly distributed in both direction and magnitude

same distance. When not specified otherwise, the gain refers to the 
direction of maximum radiation. The gain may be considered for a 
specified polarization.

    Note: Depending on the choice of the reference antenna a distinction 
is made between:
    (1) Absolute or isotropic gain (Gi), when the reference antenna is 
an isotropic antenna isolated in space;
    (2) Gain relative to a half-wave dipole (Gd), when the reference 
antenna is a half-wave

[[Page 453]]

dipole isolated in space whose equatorial plane contains the given 
direction;
    (3) Gain relative to a short vertical antenna (Gv), when the 
reference antenna is a linear conductor, much shorter than one quarter

mobile communications uses including those within the Aeronautical 
Mobile, Land Mobile, or the Maritime Mobile Services.

    (4) Non-Government operation has been certified as necessary by the 
Government agency involved and this certification has been furnished, in 
writing, to the non-Government licensee with which communication is 
required.
    (d) Aircraft stations may communicate with stations of the maritime 
mobile service. They shall then conform to those provisions of the 
international Radio Regulations which relate to the maritime mobile 
service. For this purpose aircraft stations should use the frequencies 
allocated to the maritime mobile service. However, having regard to 
interference which may be caused by aircraft stations at high altitudes, 
maritime mobile frequencies in the bands above 30 MHz shall not be used 
by aircraft stations in any specific area without the prior agreement of 
all administrations of the area in which interference is likely to be 
caused. In particular, aircraft stations operating in Region 1 should 
not use frequencies in the bands above 30 MHz allocated to the maritime 
mobile service by virtue of any agreement between administrations in 
that Region.
    (e) Non-Government services operating on frequencies in the band 25-
50 MHz must recognize that it is shared with various services of other 
countries; that harmful interference may be caused by skywave signals 
received from distant stations of all services of the United States and 
other countries radiating power on frequencies in this band; and that no 
protection from such harmful interference generally can be expected. 
Persons desiring to avoid such harmful interference should consider 
operation on available frequencies higher in the radio spectrum not 
generally subject to this type of difficulty.
    (f) The stations of a service shall use frequencies so separated 
from the limits of a band allocated to that service as not to cause 
harmful interference to allocated services in immediately adjoining 
frequency bands.
    (g) In the bands above 25 MHz which are allocated to the non-
Government land mobile service, fixed stations may be authorized on the 
following conditions:
    (1) That such stations are authorized in the service shown in Column 
5 of the Table of Frequency Allocations in the band in question;
    (2) That harmful interference will not be caused to services 
operating in accordance with the Table of Frequency Allocations.
    (h) Special provisions regarding the use of spectrum allocated to 
the fixed and land mobile services below 25 MHz by non-Government 
stations.
    (1) Only in the following circumstances will authority be extended 
to stations in the fixed service to operate on frequencies below 25 MHz.
    (i) With respect to aeronautical fixed stations, only when a showing 
can be made that more suitable facilities are not available.
    (ii) With respect to fixed stations, except aeronautical fixed 
stations, only to:
    (A) Provide communication circuits in emergency and/or disaster 
situations, where safety of life and property are concerned;
    (B) Provide standby and/or backup facilities to satellite and cable 
circuits used for international public correspondence;

[[Page 462]]

    (C) Provide standby and/or backup communications circuits to regular 
domestic communication circuits which have been disrupted by disasters 
and/or emergencies;
    (D) Provide communication circuits wholly within the State of Alaska 
and the United States insular areas in the Pacific; and
    (E) Provide communication circuits to support operations which are 
highly important to the national interest and where other means of 
telecommunication are unavailable.
    (2) Only in the following circumstances will authority be extended 
to stations in the land mobile service to operate below 25 MHz.
    (i) Provide communication circuits in emergency and/or disaster 
situations, where safety of life and property are concerned;
    (ii) Provide standby and/or backup communications circuits to 
regular domestic communication circuits which have been disrupted by 
disasters and/or emergencies;
    (iii) Provide communication circuits wholly within the State of 
Alaska and the United States insular areas in the Pacific; and
    (iv) Provide communication circuits to support operations which are 
highly important to the national interest and where other means of 
telecommunication are unavailable.
    (3) Except in the State of Alaska and the United States Pacific 
insular areas, the Commission does not intend to seek international 
protection for assignments made pursuant to paragraphs (h) (1)(ii) and 
(2) of this section; this results in the following constraints upon the 
circuits/assignments.
    (i) The Commission will not accept responsibility for protection of 
the circuits from harmful interference caused by foreign operations.
    (ii) In the event that a complaint of harmful interference resulting 
from operation of these circuits is received from a foreign source, the 
offending circuit(s) must cease operation on the particular frequency 
concerned.
    (iii) In order to accommodate the situations described in paragraphs 
(h)(3) (i) and (ii) of this section, equipments shall be capable of 
transmitting and receiving on any frequency in the bands assigned to the 
particular operation and capable of immediate change among the 
frequencies.



Sec. 2.103  Government use of non-Government frequencies.

    (a) Government stations may be authorized to use non-Government 
frequencies in the bands above 25 MHz (except the 764-776 MHz and 794-
806 MHz public safety bands) if the Commission finds that such use is 
necessary for coordination of Government and non-Government activities: 
Provided, however, that:
    (1) Government operation on non-Government frequencies shall conform 
with the conditions agreed upon by the Commission and the National 
Telecommunications and Information Administration (the more important of 
which are contained in paragraphs (a)(2), (a)(3) and (a)(4) of this 
section);
    (2) Such operations shall be in accordance with Commission rules 
governing the service to which the frequencies involved are allocated;
    (3) Such operations shall not cause harmful interference to non-
Government stations and, should harmful interference result, that the 
interfering Government operation shall immediately terminate; and
    (4) Government operation has been certified as necessary by the non-
Government licensees involved and this certification has been furnished, 
in writing, to the Government agency with which communication is 
required.
    (b) Government stations may be authorized to use channels in the 
764-776 MHz, 794-806 MHz and 4940-4990 MHz public safety bands with non-
Government entities if the Commission finds such use necessary; where:
    (1) The stations are used for interoperability or part of a 
Government/non-Government shared or joint-use system;
    (2) The Government entity obtains the approval of the non-Government 
(State/local government) licensee(s) or applicant(s) involved;
    (3) Government operation is in accordance with the Commission's 
Rules governing operation of this band and conforms with any conditions 
agreed

[[Page 463]]

upon by the Commission and the National Telecommunications and 
Information Administration; and
    (4) Interoperability, shared or joint-use systems are the subject of 
a mutual agreement between the Government and non-Government entities. 
This section does not preclude other arrangements or agreements as 
permitted under part 90 of the rules. See 47 CFR 90.179 and 90.421 of 
this chapter.

Sec. 2.104  International Table of Frequency Allocations.

    (a) The International Table of Frequency Allocations is subdivided 
into the Region 1 Table (column 1 of Sec. 2.106), the Region 2 Table 
(column 2 of Sec. 2.106), and the Region 3 Table (column 3 of Sec. 
2.106). The International Table is included for informational purposes 
only.
    (b) Regions. For the allocation of frequencies the International 
Telecommunication Union (ITU) has divided the world into three Regions 
\1\ as shown in Figure 1 of this section and described as follows:
---------------------------------------------------------------------------

    \1\ It should be noted that where the words ``regions'' or 
``regional'' are without a capital ``R,'' they do not relate to the 
three Regions here defined for purposes of frequency allocation.
---------------------------------------------------------------------------

    (1) Region 1. Region 1 includes the area limited on the east by line 
A (lines A, B and C are defined below) and on the west by line B, 
excluding any of the territory of the Islamic Republic of Iran which 
lies between these limits. It also includes the whole of the territory 
of Armenia, Azerbaijan, Russian Federation, Georgia, Kazakstan, 
Mongolia, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and 
Ukraine and the area to the north of Russian Federation which lies 
between lines A and C.
    (2) Region 2. Region 2 includes the area limited on the east by line 
B and on the west by line C.
    (3) Region 3. Region 3 includes the area limited on the east by line 
C and on the west by line A, except any of the territory of Armenia, 
Azerbaijan, Russian Federation, Georgia, Kazakstan, Mongolia, 
Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and 
the area to the north of Russian Federation. It also includes that part 
of the territory of the Islamic Republic of Iran lying outside of those 
limits.
    (4) The lines A, B and C are defined as follows:
    (i) Line A. Line A extends from the North Pole along meridian 
40[deg] East of Greenwich to parallel 40[deg] North; thence by great 
circle arc to the intersection of meridian 60[deg] East and the Tropic 
of Cancer; thence along the meridian 60[deg] East to the South Pole.
    (ii) Line B. Line B extends from the North Pole along meridian 
10[deg] West of Greenwich to its intersection with parallel 72[deg] 
North; thence by great circle arc to the intersection of meridian 
50[deg] West and parallel 40[deg] North; thence by great circle arc to 
the intersection of meridian 20[deg] West and parallel 10[deg] South; 
thence along meridian 20[deg] West to the South Pole.
    (iii) Line C. Line C extends from the North Pole by great circle arc 
to the intersection of parallel 65[deg]30[min] North with the 
international boundary in Bering Strait; thence by great circle arc to 
the intersection of meridian 165[deg] East of Greenwich and parallel 
50[deg] North; thence by great circle arc to the intersection of 
meridian 170[deg] West and parallel 10[deg] North; thence along parallel 
10[deg] North to its intersection with meridian 120[deg] West; thence 
along meridian 120[deg] West to the South Pole.
    (c) Areas. To further assist in the international allocation of the 
radio spectrum, the ITU has established five special geographical areas 
and they are defined as follows:
    (1) The term ``African Broadcasting Area'' means:
    (i) African countries, parts of countries, territories and groups of 
territories situated between the parallels 40[deg] South and 30[deg] 
North;
    (ii) Islands in the Indian Ocean west of meridian 60[deg] East of 
Greenwich, situated between the parallel 40[deg] South and the great 
circle arc joining the points 45[deg] East, 11[deg]30[min] North and 
60[deg] East, 15[deg] North; and
    (iii) Islands in the Atlantic Ocean east of line B, situated between 
the parallels 40[deg] South and 30[deg] North.
    (2) The ``European Broadcasting Area'' is bounded on the west by the

[[Page 464]]

western boundary of Region 1, on the east by the meridian 40[deg] East 
of Greenwich and on the south by the parallel 30[deg] North so as to 
include the northern part of Saudi Arabia and that part of those 
countries bordering the Mediterranean within these limits. In addition, 
Iraq, Jordan and that part of the territory of Syria, Turkey and Ukraine 
lying outside the above limits are included in the European Broadcasting 
Area.
    (3) The ``European Maritime Area'' is bounded to the north by a line 
extending along parallel 72[deg] North from its intersection with 
meridian 55[deg] East of Greenwich to its intersection with meridian 
5[deg] West, then along meridian 5[deg] West to its intersection with 
parallel 67[deg] North, thence along parallel 67[deg] North to its 
intersection with meridian 32[deg] West; to the west by a line extending 
along meridian 32[deg] West to its intersection with parallel 30[deg] 
North; to the south by a line extending along parallel 30[deg] North to 
its intersection with meridian 43[deg] East; to the east by a line 
extending along meridian 43[deg] East to its intersection with parallel 
60[deg] North, thence along parallel 60[deg] North to its intersection 
with meridian 55[deg] East and thence along meridian 55[deg] East to its 
intersection with parallel 72[deg] North.
    (4) The ``Tropical Zone'' (see Figure 1 of this section) is defined 
as:
    (i) The whole of that area in Region 2 between the Tropics of Cancer 
and Capricorn.
    (ii) The whole of that area in Regions 1 and 3 contained between the 
parallels 30[deg] North and 35[deg] South with the addition of:
    (A) The area contained between the meridians 40[deg] East and 
80[deg] East of Greenwich and the parallels 30[deg] North and 40[deg] 
North; and
    (B) That part of Libya north of parallel 30[deg] North.
    (iii) In Region 2, the Tropical Zone may be extended to parallel 
33[deg] North, subject to special agreements between the countries 
concerned in that Region.
    (5) A sub-Region is an area consisting of two or more countries in 
the same Region.
    (d) Categories of services and allocations. (1) Primary and 
secondary services. Where, in a box of the International Table in Sec. 
2.106, a band is indicated as allocated to more than one service, either 
on a worldwide or Regional basis, such services are listed in the 
following order:
    (i) Services the names of which are printed in ``capitals'' 
(example: FIXED); these are called ``primary'' services; and
    (ii) Services the names of which are printed in ``normal 
characters'' (example: Mobile); these are called ``secondary'' services 
(see paragraph (d)(3) of this section).
    (2) Additional remarks shall be printed in normal characters 
(example: MOBILE except aeronautical mobile).
    (3) Stations of a secondary service:
    (i) Shall not cause harmful interference to stations of primary 
services to which frequencies are already assigned or to which 
frequencies may be assigned at a later date;
    (ii) Cannot claim protection from harmful interference from stations 
of a primary service to which frequencies are already assigned or may be 
assigned at a later date; and
    (iii) Can claim protection, however, from harmful interference from 
stations of the same or other secondary service(s) to which frequencies 
may be assigned at a later date.
    (4) Where a band is indicated in a footnote of the International 
Table as allocated to a service ``on a secondary basis'' in an area 
smaller than a Region, or in a particular country, this is a secondary 
service (see paragraph (d)(3) of this section).
    (5) Where a band is indicated in a footnote of the International 
Table as allocated to a service ``on a primary basis'', in an area 
smaller than a Region, or in a particular country, this is a primary 
service only in that area or country.
    (e) Additional allocations. (1) Where a band is indicated in a 
footnote of the International Table as ``also allocated'' to a service 
in an area smaller than a Region, or in a particular country, this is an 
``additional'' allocation, i.e. an allocation which is added in this 
area or in this country to the service or services which are indicated 
in the International Table.

[[Page 465]]

    (2) If the footnote does not include any restriction on the service 
or services concerned apart from the restriction to operate only in a 
particular area or country, stations of this service or these services 
shall have equality of right to operate with stations of the other 
primary service or services indicated in the International Table.
    (3) If restrictions are imposed on an additional allocation in 
addition to the restriction to operate only in a particular area or 
country, this is indicated in the footnote of the International Table.
    (f) Alternative allocations. (1) Where a band is indicated in a 
footnote of the International Table as ``allocated'' to one or more 
services in an area smaller than a Region, or in a particular country, 
this is an ``alternative'' allocation, i.e. an allocation which 
replaces, in this area or in this country, the allocation indicated in 
the Table.
    (2) If the footnote does not include any restriction on stations of 
the service or services concerned, apart from the restriction to operate 
only in a particular area or country, these stations of such a service 
or services shall have an equality of right to operate with stations of 
the primary service or services, indicated in the International Table, 
to which the band is allocated in other areas or countries.
    (3) If restrictions are imposed on stations of a service to which an 
alternative allocation is made, in addition to the restriction to 
operate only in a particular country or area, this is indicated in the 
footnote.
    (g) Miscellaneous provisions. (1) Where it is indicated that a 
service may operate in a specific frequency band subject to not causing 
harmful interference, this means also that this service cannot claim 
protection from harmful interference caused by other services to which 
the band is allocated under Chapter SII of the international Radio 
Regulations.
    (2) Except if otherwise specified in a footnote, the term ``fixed 
service'', where appearing in the International Table, does not include 
systems using ionospheric scatter propagation.
    (h) Description of the International Table of Frequency Allocations. 
(1) The heading of the International Table includes three columns, each 
of which corresponds to one of the Regions (see paragraph (b) of this 
section). Where an allocation occupies the whole of the width of the 
Table or only one or two of the three columns, this is a worldwide 
allocation or a Regional allocation, respectively.
    (2) The frequency band referred to in each allocation is indicated 
in the left-hand top corner of the part of the Table concerned.
    (3) Within each of the categories specified in paragraph (d)(1) of 
this section, services are listed in alphabetical order according to the 
French language. The order of listing does not indicate relative 
priority within each category.
    (4) In the case where there is a parenthetical addition to an 
allocation in the International Table, that service allocation is 
restricted to the type of operation so indicated.
    (5) The footnote references which appear in the International Table 
below the allocated service or services apply to the whole of the 
allocation concerned.
    (6) The footnote references which appear to the right of the name of 
a service are applicable only to that particular service.
    (7) In certain cases, the names of countries appearing in the 
footnotes have been simplified in order to shorten the text.

Sec. 2.105  United States Table of Frequency Allocations.

    (a) The United States Table of Frequency Allocations (United States 
Table) is subdivided into the Federal Government Table of Frequency 
Allocations (Federal Government Table, column 4 of Sec. 2.106) and the 
Non-Federal Government Table of Frequency Allocations (Non-Federal 
Government Table, column 5 of Sec. 2.106). The United States Table is 
based on the Region 2 Table because the relevant area of jurisdiction is 
located primarily in Region 2 \1\ (i.e., the 50 States, the District of 
Columbia, the Caribbean insular areas \2\ and some of the Pacific 
insular areas).\3\ \4\ The Federal Government Table is administered by 
the National Telecommunications and Information Administration (NTIA) 
\5\, whereas the Non-Federal Government Table is administered by the 
Federal Communications Commission (FCC).\6\
---------------------------------------------------------------------------

    \1\ See Sec. 2.104(a)(1) for definition of Region 2.
    \2\ The Caribbean insular areas are: The Commonwealth of Puerto 
Rico; the unincorporated territory of the United States Virgin Islands; 
and Navassa Island.
    \3\ The Pacific insular areas located in Region 2 are: Johnston 
Atoll and Midway Atoll.
    \4\ The operation of stations in the Pacific insular areas located 
in Region 3 are generally governed by the International plan for Region 
3 (i.e., column 3 of Sec. 2.106). The Pacific insular areas located in 
Region 3 are: the Commonwealth of the Northern Mariana Islands; the 
unincorporated territory of American Samoa; the unincorporated territory 
of Guam; and Baker Island, Howland Island, Jarvis Island, Kingman Reef, 
Palmyra Island and Wake Island.
    \5\ Section 305(a) of the Communications Act of 1934, as amended. 
See Pub. Law 102-538, 106 Stat. 3533 (1992).
    \6\ The Communications Act of 1934, as amended.
---------------------------------------------------------------------------

    (b) In the United States, radio spectrum may be allocated to either 
Federal government or non-Federal government use exclusively, or for 
shared use. In the case of shared use, the type of service(s) permitted 
need not be the same [e.g., Federal government FIXED, non-Federal 
government MOBILE]. The terms used to designate categories of services 
and allocations \7\ in columns 4 and 5 of Sec. 2.106 correspond to the 
terms employed by the International Telecommunication Union (ITU) in the 
international Radio Regulations.
---------------------------------------------------------------------------

    \7\ Definitions of the various radio services used are contained in 
Sec. 2.1.
---------------------------------------------------------------------------

    (c) Category of services. (1) Any segment of the radio spectrum may 
be allocated to the Federal government and/or non-Federal government 
sectors either on an exclusive or shared basis for use by one or more 
radio services. In the case where an allocation has been made to more 
than one service, such services are listed in the following order:
    (i) Services, the names of which are printed in ``capitals'' 
[example: FIXED]; these are called ``primary'' services;
    (ii) Services, the names of which are printed in ``normal 
characters'' [example: Mobile]; these are called ``secondary'' services.
    (2) Stations of a secondary service:
    (i) Shall not cause harmful interference to stations of primary 
services to which frequencies are already assigned or to which 
frequencies may be assigned at a later date;
    (ii) Cannot claim protection from harmful interference from stations 
of a primary service to which frequencies are already assigned or may be 
assigned at a later date; and
    (iii) Can claim protection, however, from harmful interference from 
stations of the same or other secondary service(s) to which frequencies 
may be assigned at a later date.
    (d) Format of the United States Table and the Rule Part Cross 
Reference Column. (1) The frequency band referred to in each allocation, 
column 4 for Federal government and column 5 for non-Federal government, 
is indicated in the left-hand top corner of the column. If there is no 
service or footnote indicated for a band of frequencies in either column 
4 or 5, then the Federal government or the non-Federal government 
sector, respectively, has no access to that band except as provided for 
by Sec. 2.102.
    (2) When the Federal Government and Non-Federal Government Tables 
are exactly the same for a shared band, the line between columns 4 and 5 
is deleted and the allocations are shown once.
    (3) The Federal Government Table, given in column 4, is included for 
informational purposes only.

[[Page 468]]

    (4) In the case where there is a parenthetical addition to an 
allocation in the United States Table [example: FIXED-SATELLITE (space-
to-earth)], that service allocation is restricted to the type of 
operation so indicated.
    (5) The following symbols are used to designate footnotes in the 
United States Table:
    (i) Any footnote consisting of ``S5.'' followed by one or more 
digits, e.g., S5.53, or any footnote not prefixed by a letter, e.g., 
459, denotes an international footnote. Where an international footnote 
is applicable, without modification, to the United States Table, the 
footnote appears in the United States Table (columns 4 and 5) and 
denotes a stipulation affecting both the Federal Government Table and 
the Non-Federal Government Table. If, however, an international footnote 
pertains to a service allocated only for Federal government or non-
Federal government use, the international footnote will be placed only 
in the affected Table. For example, ``AMATEUR S5.142'' shall be shown 
only in the Non-Federal Government Table.
    (ii) Any footnote consisting of the letters US followed by one or 
more digits, e.g., US7, denotes a stipulation affecting both the Federal 
Government Table and the Non-Federal Government Table.
    (iii) Any footnote consisting of the letters NG followed by one or 
more digits, e.g., NG2, denotes a stipulation applicable only to the 
Non-Federal Government Table (column 5).
    (iv) Any footnote consisting of the letter G following by one or 
more digits, e.g., G2, denotes a stipulation applicable only to the 
Federal Government Table (column 4).
    (6) If a frequency or frequency band has been allocated to a 
radiocommunication service in the Non-Federal Government Table, then a 
cross reference may be added for the pertinent FCC Rule part (column 6 
of Sec. 2.106). For example, the 849-851 MHz band is allocated to the 
non-Federal government aeronautical mobile service, rules for the use of 
the 849-851 MHz band have been added to Part 22--Public Mobile Services 
(47 CFR part 22), and a cross reference, Public Mobile (22), has been 
added in Column 6 of the Table. The exact use that can be made of any 
given frequency or frequency band (e.g., channelling plans, allowable 
emissions, etc.) is given in the FCC Rule part(s) so indicated. The FCC 
Rule parts in this column are not allocations and are provided for 
informational purposes only. This column also may contain explanatory 
notes for informational purposes only.

the Commission's Rules and Regulations, Part 87, Aviation Services;

[[Page 599]]

    (b) Use of the frequency is required for coordination of activities 
with Commission licensees operating on this frequency; and
    (c) Government stations will not be authorized for operation at 
fixed locations.
    US81 The band 38.0-38.25 MHz is used by both Government and non-
Government radio astronomy observatories. No new fixed or mobile 
assignments are to be made and Government stations in the band 38.0-
38.25 MHz will be moved to other bands on a case-by-case basis, as 
required, to protect radio astronomy observations from harmful 
interference. As an exception, however, low powered military 
transportable and mobile stations used for tactical and training 
purposes will continue to use the band. To the extent practicable, the 
latter operations will be adjusted to relieve such interference as may 
be caused to radio astronomy observations. In the event of harmful 
interference from such local operations, radio astronomy observatories 
may contact local military commands directly, with a view to effecting 
relief. A list of military commands, areas of coordination, and points 
of contact for purposes of relieving interference may be obtained upon 
request from the Office of the Chief Engineer, Federal Communications 
Commission, Washington, D.C. 20554.

applied on a case-by-case basis.
    US90 In the band 2025-2110 MHz, the power flux-density at the 
Earth's surface produced by emissions from a space station in the space 
operation, Earth exploration-satellite, or space research services that 
is transmitting in the space-to-space direction, for all conditions and 
all methods of modulation, shall not exceed the following values in any 
4 kHz sub-band:
    (a) -154 dBW/m\2\ for angles of arrival above the horizontal plane 
([delta]) of 0[deg] to 5[deg],
    (b) -154 + 0.5([delta]-5) dBW/m\2\ for [delta] of 5[deg] to 25[deg], 
and
    (c) -144 dBW/m\2\ for [delta] of 25[deg] to 90[deg].
    US93 In the conterminous United States, the frequency 108.0 MHz may 
be authorized for use by VOR test facilities, the operation of which is 
not essential for the safety of life or property, subject to the 
condition that no interference is caused to the reception of FM 
broadcasting stations operating in the band 88-108 MHz. In the event 
that such interference does occur, the licensee or other agency 
authorized to operate the facility shall discontinue operation on 108 
MHz and shall not resume operation until the interference has been 
eliminated or the complaint otherwise satisfied. VOR test facilities 
operating on 108 MHz will not be protected against interference caused 
by FM broadcasting stations operating in the band 88-108 MHz not shall 
the authorization of a VOR test facility on 108 MHz preclude the 
Commission from authorizing additional FM broadcasting stations.
    US99 In the band 1668.4-1670.0 MHz, the meteorological aids service 
(radiosonde) will avoid operations to the maximum extent practicable. 
Whenever it is necessary to operate radiosondes in the band 1668.4-1670 
MHz within the United States, notification of the operations shall be 
sent as far in advance as possible to the Electromagnetic Management 
Unit, National Science Foundation, Washington, D.C. 20550.

110 kHz in the United States and its insular areas. Radiolocation land 
stations making use of LORAN-type equipment may be authorized to both 
Federal and non-Federal Government licensees on a secondary basis for 
offshore radiolocation activities only at specific locations and subject 
to such technical and operational conditions (e.g., power, emission, 
pulse rate and phase code, hours of operation), including on-the-air 
testing, as may be required on a case-by-case basis to ensure protection 
of the LORAN radionavigation system from harmful interference and to 
ensure mutual compatibility among radiolocation operators. Such 
authorizations to stations in the radiolocation service are further 
subject to showing of need for service which is not currently provided 
and which the Federal Government is not yet prepared to render by way of 
the radionavigation service.
    US106 The frequency 156.75 MHz is available for assignment to non-
Government and Government stations for environmental communications in 
accordance with an agreed plan.
    US107 The frequency 156.8 MHz is the national distress, safety and 
calling frequency for the maritime mobile VHF radiotelephone service for 
use by Government and non-Government ship and coast stations. Guard 
bands of 156.7625-156.7875 and 156.8125-156.8375 MHz are maintained.
    US108 Within the bands 3300-3500 MHz and 10000-10500 MHz, survey 
operations, using

    In the bands 1350-1400 MHz and 4950-4990 MHz, every practicable 
effort will be made to avoid the assignment of frequencies to stations 
in the fixed and mobile services that could interfere with radio 
astronomy observations within the geographic areas given above. In 
addition, every practicable effort will be made to avoid assignment of 
frequencies in these bands to stations in the aeronautical mobile 
service which operate outside of those geographic areas, but which may 
cause harmful interference to the listed observatories. Should such 
assignments result in harmful interference to these observatories, the 
situation will be remedied to the extent practicable.

station or from a Government space station in a NGSO constellation of 50 
or fewer satellites, for all conditions and for all methods of 
modulation, shall not exceed the following values in any 1 MHz band:
    (1) -115 dB(W/m \2\) for angles of arrival above the horizontal 
plane ([delta]) between 0[deg] and 5[deg],
    (2) -115 + 0.5 ([delta]-5) dB(W/m \2\) for [delta] between 5[deg] 
and 25[deg], and
    (3) -105 dB(W/m \2\) for [delta] between 25[deg] and 90[deg].
    (b) In the sub-band 17.8-19.3 GHz, the power flux-density at the 
surface of the Earth produced by emissions from a Government space 
station in an NGSO constellation of 51 or more satellites, for all 
conditions and for all methods of modulation, shall not exceed the 
following values in any 1 MHz band:
    (1) -115 -X dB(W/m \2\) for [delta] between 0[deg] and 5[deg],
    (2) -115 -X + ((10 + X)/20) ([delta]-5) dB(W/m \2\) for [delta] 
between 5[deg] and 25[deg], and
    (3) -105 dB(W/m \2\) for [delta] between 25[deg] and 90[deg]; where 
X is defined as a function of the number of satellites, n, in an NGSO 
constellation as follows:

[[Page 608]]

    For n <= 288, X = (5/119) (n-50) dB; and
    For n  288, X = (1/69) (n+ 402) dB.
    US335 The primary Government and non-Government allocations for the 
various segments of the 220-222 MHz band are divided as follows: (1) the 
220.0-220.55/221.0-221.55, 220.6-220.8/221.6-221.8, 220.85-220.90/
221.85-221.90 and 220.925-221.0/221.925-222.0 MHz bands (Channels 1-110, 
121-160, 171-180 and 186-200, respectively) are available for exclusive 
non-Government use; (2) the 220.55-220.60/221.55-221.60 MHz bands 
(Channels 111-120) are available for exclusive Government use; and (3) 
the 220.80-220.85/221.80-221.85 and 220.900-220.925/221.900-221.925 MHz 
bands (Channels 161-170 and 181-185, respectively) are available for 
shared Government and non-Government use. The exclusive non-Government 
band segments are also available for temporary fixed geophysical 
telemetry operations on a secondary basis to the fixed and mobile 
services.
    US337 In the band 13.75-13.80 GHz, earth stations in the fixed-
satellite service shall be coordinated on a case-by-case basis through 
the frequency assignment subcommittee in order to minimize harmful 
interference to the Tracking and Data Relay Satellite System's forward 
space-to-space link (TDRSS forward link-to-LEO).
    US338 In the 2305-2310 MHz band, space-to-Earth operations are 
prohibited. Additionally, in the 2305-2320 MHz band, all Wireless 
Communications Service (WCS) operations within 50 kilometers of 
35[deg]20[sec] North Latitude and 116[deg]53[sec] West Longitude shall 
be coordinated through the Frequency Assignment Subcommittee of the 
Interdepartment Radio Advisory Committee in order to minimize harmful 
interference to NASA's Goldstone Deep Space facility.
    US339 The bands 2310-2320 and 2345-2360 MHz are also available for 
aeronautical telemetering and associated telecommand operations for 
flight testing of manned or unmanned aircraft, missiles or major 
components thereof on a secondary basis to the Wireless Communications 
Service. The following two frequencies are shared on a co-equal basis by 
Government and non-Government stations for telemetering and associated 
telecommand operations of expendable and re-usable launch vehicles 
whether or not such operations involve flight testing: 2312.5 and 2352.5 
MHz. Other mobile telemetering uses may be provided on a non-
interference basis to the above uses. The broadcasting-satellite (sound) 
service during implementation should also take cognizance of the 
expendable and reusable launch vehicle frequencies 2312.5 and 2352.5 
MHz, to minimize the impact on this mobile service use to the extent 
possible.
    US340 The band 2-30 MHz is available on a non-interference basis to 
Federal and non-Federal Government maritime and aeronautical stations 
for the purposes of measuring the quality of reception on radio 
channels. See 47 CFR 87.149 for the list of protected frequencies and 
bands within this frequency range. Actual communications shall be 
limited to those frequencies specifically allocated to the maritime 
mobile and aeronautical mobile services.

    US344 In the band 5091-5250 MHz, non-Government earth stations in 
the fixed-satellite service (Earth-to-space) shall be coordinated 
through the Frequency Assignment Subcommittee (see Recommendation ITU-R 
S.1342). In order to better protect the operation of the international 
standard system (microwave landing system) in the band 5000-5091 MHz, 
non-Government tracking and telecommand operations should be conducted 
in the band 5150-5250 MHz.
    US345 In the band 402-405 MHz, the mobile, except mobile 
aeronautical, service is allocated on a secondary basis and is limited 
to, with the exception of military tactical mobile stations, Medical 
Implant Communications Service (MICS) operations. MICS stations are 
authorized by rule on the condition that harmful interference is not 
caused to stations in the meteorological aids, meteorological-satellite, 
and earth exploration-satellite services, and that MICS stations accept 
interference from stations in the meteorological aids, meteorological-
satellite, and earth exploration-satellite services.
    US346 Except as provided by footnote US222, the use of the band 
2025-2110 MHz by the Government space operation service (Earth-to-
space), Earth exploration-satellite service (Earth-to-space), and space 
research service (Earth-to-space) shall not constrain the deployment of 
the Television Broadcast Auxiliary Service, the Cable Television Relay 
Service, or the Local Television Transmission Service. To facilitate 
compatible operations between non-Government terrestrial receiving 
stations at fixed sites and Government earth station transmitters, 
coordination is required. To facilitate compatible operations between 
non-government terrestrial transmitting stations and Government 
spacecraft receivers, the terrestrial transmitters shall not be high-
density systems (see Recommendations ITU-R SA.1154 and ITU-R F.1247).
    US347 In the band 2025-2110 MHz, non-Government Earth-to-space and 
space-to-space transmissions may be authorized in the space research and 
Earth exploration-satellite services subject to such conditions as may 
be applied on a case-by-case basis. Such transmissions shall not cause 
harmful interference to Government and non-Government stations operating 
in accordance with the Table of Frequency Allocations.
    US348 The band 3650-3700 MHz is also allocated to the Government 
radiolocation service on a primary basis at the following sites: St. 
Inigoes, MD (38[deg]10[min] N., 76[deg]23[min] W.); Pascagoula, MS

(30[deg]21[min]28[sec] N., 87[deg]16[min]26[sec] W.). All fixed and 
fixed satellite operations within 80 kilometers of these sites shall be 
coordinated through the Frequency Assignment Subcommittee of the 
Interdepartmental Radio Advisory Committee on a case-by-case basis.
    US349 The band 3650-3700 MHz is also allocated to the Government 
radiolocation service on a non-interference basis for use by ship 
stations located at least 44 nautical miles in off-shore ocean areas on 
the condition that harmful interference is not caused to non-Government 
operations.
    US350 In the bands 608-614 MHz and 1395-1400 MHz the Government and 
non-Government land mobile service is limited to medical telemetry and

    US356 In the band 13.75-14 GHz, an earth station in the fixed-
satellite service shall have a minimum antenna diameter of 4.5 m and the 
e.i.r.p. of any emission should be at least 68 dBW and should not exceed 
85 dBW. In addition the e.i.r.p., averaged over one second, radiated by 
a station in the radiolocation service shall not exceed 59 dBW. 
Receiving space stations in the fixed-satellite service shall not claim 
protection from radiolocation transmitting stations operating in 
accordance with the United States

[[Page 611]]

Table of Frequency Allocations. ITU Radio Regulation No. 5.43A does not 
apply.
    US357 In the band 13.75-14 GHz, geostationary space stations in the 
space research service for which information for advance publication has 
been received by the ITU Radiocommunication Bureau (Bureau) prior to 31 
January 1992 shall operate on an equal basis with stations in the fixed-
satellite service; after that date, new geostationary space stations in 
the space research service will operate on a secondary basis. Until 
those geostationary space stations in the space research service for 
which information for advance publication has been received by the 
Bureau prior to 31 January 1992 cease to operate in this band:
    a. The e.i.r.p. density of emissions from any earth station in the 
fixed-satellite service operating with a space station in geostationary-
satellite orbit shall not exceed 71 dBW in any 6 MHz band from 13.77 to 
13.78 GHz;
    b. The e.i.r.p. density of emissions from any earth station in the 
fixed-satellite service operating with a space station in non-
geostationary-satellite orbit shall not exceed 51 dBW in any 6 MHz band 
from 13.77 to 13.78 GHz.
    Automatic power control may be used to increase the e.i.r.p. density 
in any 6 MHz band in these frequency ranges to compensate for rain 
attenuation, to the extent that the power flux-density at the fixed-
satellite service space station does not exceed the value resulting from 
use by an earth station of an e.i.r.p. of 71 dBW or 51 dBW, as 
appropriate, in any 6 MHz band in clear-sky conditions.
    US359 In the band 15.43-15.63 GHz, use of the fixed-satellite 
service (Earth-to-space) is limited to non-Government feeder links of 
non-geostationary systems in the mobile-satellite service. These non-
Government earth stations shall be coordinated through the Frequency 
Assignment Subcommittee (see Annex 3 of Recommendation ITU-R S.1340).
    US360 In the band 33-36 GHz, the Government fixed-satellite service 
(space-to-Earth) is also allocated on a primary basis. Coordination 
between Government fixed-satellite service systems and non-Government 
systems operating in accordance with the United States Table of 
Frequency Allocations is required.
    US361 In the band 1432-1435 MHz, Government stations in the fixed 
and mobile services may operate indefinitely on a primary basis at the 
23 sites listed in the following table. All other Government stations in 
the fixed and mobile services shall operate in the band 1432-1435 MHz on

    US364 Consistent with US18, stations may be authorized on a primary 
basis in the band 285-325 kHz for the specific purpose of transmitting 
differential global positioning system information.
    US366 On April 1, 2007, the bands 5900-5950 kHz, 7300-7350 kHz, 
9400-9500 kHz, 11600-11650 kHz, 12050-12100 kHz, 13570-13600 kHz, 13800-
13870 kHz, 15600-15800 kHz, 17480-17550 kHz, and 18900-19020 kHz shall 
be allocated exclusively to the broadcasting service. Beginning April 1, 
2007, frequencies in these bands may be used by stations in the fixed 
and mobile services, communicating only within the United States and its 
insular areas, on the condition that harmful interference is not caused 
to the broadcasting service. When using frequencies for fixed and mobile 
services, licensees shall be limited to the minimum power needed to 
achieve communications and shall take account of the seasonal use of 
frequencies by the broadcasting service published in accordance with 
Article 12 of the ITU Radio Regulations.
    US367 On the condition that harmful interference is not caused to 
the broadcasting service, frequencies in the bands 9775-9900 kHz, 11650-
11700 kHz, and 11975-12050 kHz may be used by Federal Government 
stations in the fixed service communicating within the United States and 
its insular areas that are authorized as of [effective date of the 
Report and Order published in the Federal Register]. Each such station 
shall be limited to a total radiated power of 24 dBW.
    US368 The band 1390-1392 MHz is also allocated to the fixed-
satellite service (Earth-to-space) on a primary basis and the band 1430-
1432 MHz is also allocated to the fixed-satellite service (space-to-
Earth) on a primary basis, limited to feeder links for the Non-Voice 
Non-Geostationary Mobile-Satellite Service, and contingent on (1) the 
completion of sharing studies including the measurement of emissions 
from equipment that would be employed in operational systems and 
demonstrations to validate the studies as called for in Resolution 127 
(WRC-2000), (2) the adoption of worldwide feeder link allocations at the 
2003 World Radiocommunication Conference (WRC-03), and (3) compliance 
with any technical and operational requirements that may be imposed at 
WRC-03 to protect passive services in the 1400-1427 MHz band from 
unwanted emissions associated

[[Page 613]]

with such allocations. These allocations become effective upon adoption 
of worldwide allocations at WRC-03. If no such allocations are adopted 
by WRC-03, these allocations shall be considered null and void, with no 
grandfathering of rights. Individual assignments shall be coordinated 
with the Interdepartmental Radio Advisory Committee's (IRAC) Frequency 
Assignment Subcommittee (FAS) (see, for example, Recommendations ITU-R 
RA.769-1 and ITU R SA.1029-1) to ensure the protection of passive 
services in the 1400-1427 MHz band. Coordination shall not be completed 
until the feeder downlink system is tested and certified to be in 
conformance with the technical and operational requirements for the 
protection of passive services in the 1400-1427 MHz band. Certification 
and all supporting documentation shall be submitted to the Commission 
and FAS prior to launch.
    US370 The band 5000-5150 MHz is to be used for the operation of the 
international standard system (microwave landing system) for precision 
approach and landing. The requirements of this system shall take 
precedence over other uses of this band. For the use of this band, ITU 
Radio Regulation No. 5.444A and Resolution 114 (WRC-95) apply.
    US378 In the band 1710-1755 MHz, Federal government stations in the 
fixed and mobile services shall operate on a primary basis until 
reaccommodated in accordance with the Strom Thurmond National Defense 
Authorization Act for Fiscal Year 1999. Further, Federal government 
stations may continue to operate in the band 1710-1755 MHz as provided

accommodated satisfactorily elsewhere in the spectrum, such operations 
will, insofar as practicable, be adjusted to meet the requirements of 
the aeronautical radionavigation service.
    G19 Use of the band 9000-9200 MHz by military fixed and shipborne 
air defense radiolocation installations will be fully coordinated with 
the aeronautical radionavigation service, recognizing fully the safety 
aspects of the latter. Military air defense installations will be 
accommodated ultimately outside this band. Until such time as military 
defense installations can be accommodated satisfactorily elsewhere in 
the spectrum such operations will, insofar as practicable, be adjusted 
to meet the requirements of the aeronautical radionavigation services.
    G27 In the bands 255-328.6 MHz, 335.4-399.9 MHz, and 1350-1390 MHz,

secondary to military radiolocation, except in the sub-band 15.7-16.2 
GHz airport surface detection equipment (ASDE) is permitted on a co-
equal basis subject to coordination with the military departments.
    G100 The bands 235-322 MHz and 335.4-399.9 MHz are also allocated on 
a primary basis to the mobile-satellite service, limited to military 
operations.
    G104 In the bands 7450-7550 and 8175-8215 MHz, it is agreed that 
although the military space radio communication systems, which include 
earth stations near the proposed meteorological-satellite installations 
will precede the meteorological-satellite installations, engineering 
adjustments to either the military or the meteorological-satellite 
systems or both will be made as mutually required to assure compatible 
operations of the systems concerned.
    G106 The bands 2501-2502 kHz, 5003-5005 kHz, 10003-10005 kHz, 15005-

military systems.
    G118 Government fixed stations may be authorized in the band 1700-
1710 MHz only if spectrum is not available in the band 1710-1850 MHz.
    G120 Development of airborne primary radars in the band 2310-2385 
MHz with peak transmitter power in excess of 250 watts for use in the 
United States is not permitted.
    G122 In the bands 2390-2400 MHz, 2402-2417 MHz, and 4940-4990 MHz, 
Government operations may be authorized on a non-interference basis to 
authorized non-Government operations, but shall not hinder the 
implementation of any non-Government operations.
    G123 The bands 2300-2310 and 2400-2402 MHz were identified for 
reallocation, effective August 10, 1995, for exclusive non-Government 
use under Title VI of the Omnibus Budget Reconciliation Act of 1993. 
Effective August 10, 1995, any Government operations in these bands are 
on a non-interference basis to authorized non-Government operations and

Sec. 2.107  Radio astronomy station notification.

    (a) Pursuant to No. 1492 of Article 13 and Section F of Appendix 3 
to the

[[Page 623]]

international Radio Regulations (Geneva, 1982), operators of radio 
astronomy stations desiring international recognition of their use of 
specific radio astronomy frequencies or bands of frequencies for 
reception, should file the following information with the Commission for 
inclusion in the Master International Frequency Register:
    (1) The center of the frequency band observed, in kilohertz up to 
28,000 kHz inclusive, in megahertz above 28,000 kHz to 10,500 MHz 
inclusive and in gigahertz above 10,500 MHz.
    (2) The date (actual or foreseen, as appropriate) when reception of 
the frequency band begins.
    (3) The name and location of the station, including geographical 
coordinates in degrees and minutes.
    (4) The width of the frequency band (in kHz) observed by the 
station.
    (5) The antenna type and dimensions, effective area and angular 
coverage in azimuth and elevation.
    (6) The regular hours of reception (in UTC) of the observed 
frequency.
    (7) The overall receiving system noise temperature (in kelvins) 
referred to the output of the receiving antenna.
    (8) The class of observations to be taken. Class A observations are 
those in which the sensitivity of the equipment is not a primary factor. 
Class B observations are those of such a nature that they can be made 
only with advanced low-noise receivers using the best techniques.
    (9) The name and mailing address of the operator.
    (b) The permanent discontinuance of observations, or any change to 
the information above, should also be filed with the Commission.
    (c) Observations being conducted on frequencies or frequency bands 
not allocated to the radio astronomy service should be reported as in 
paragraph (a) of this section for information purposes. Information in 
this category will not be submitted for entry in the Master 
International Frequency Register and protection from interference will 
not be afforded such operations by stations in other services.



Sec. 2.108  Policy regarding the use of the fixed-satellite allocations 
in the 3.6-3.7, 4.5-4.8, and 5.85-5.925 GHz bands.

    The use of the fixed-satellite allocations in the United States in 
the above bands will be governed by footnote US245. Use of the fixed-
satellite service allocations in these bands is for the international 
fixed-satellite service, that is, for international inter-continental 
communications. Case-by-case electromagnetic compatibility analysis is 
required with all users of the bands. It is anticipated that one earth 
station on each coast can be successfully coordinated. Specific 
locations of these earth stations depend upon service requirements and 
case-by-case EMC analyses that demonstrate compatible operations.



                           Subpart C_Emissions



Sec. 2.201  Emission, modulation, and transmission characteristics.

    The following system of designating emission, modulation, and 
transmission characteristics shall be employed.
    (a) Emissions are designated according to their classification and 
their necessary bandwidth.
    (b) A minimum of three symbols are used to describe the basic 
characteristics of radio waves. Emissions are classified and symbolized 
according to the following characteristics:
    (1) First symbol--type of modulation of the main character;
    (2) Second symbol--nature of signal(s) modulating the main carrier;
    (3) Third symbol--type of information to be transmitted.

    Note: A fourth and fifth symbol are provided for additional 
information and are shown in Appendix 6, part A of the ITU Radio 
Regulations. Use of the fourth and fifth symbol is optional. Therefore, 
the symbols may be used as described in Appendix 6, but are not required 
by the Commission.

symbol for that emission, as given above, shall be preceded by the 
necessary bandwidth of the emission as indicated in Sec. 2.202(b)(1).

[49 FR 48697, Dec. 14, 1984]

[[Page 625]]



Sec. 2.202  Bandwidths.

    (a) Occupied bandwidth. The frequency bandwidth such that, below its 
lower and above its upper frequency limits, the mean powers radiated are 
each equal to 0.5 percent of the total mean power radiated by a given 
emission. In some cases, for example multichannel frequency-division 
systems, the percentage of 0.5 percent may lead to certain difficulties 
in the practical application of the definitions of occupied and 
necessary bandwidth; in such cases a different percentage may prove 
useful.
    (b) Necessary bandwidth. For a given class of emission, the minimum 
value of the occupied bandwidth sufficient to ensure the transmission of 
information at the rate and with the quality required for the system 
employed, under specified conditions. Emissions useful for the good 
functioning of the receiving equipment as, for example, the emission 
corresponding to the carrier of reduced carrier systems, shall be 
included in the necessary bandwidth.
    (1) The necessary bandwidth shall be expressed by three numerals and 
one letter. The letter occupies the position of the decimal point and 
represents the unit of bandwidth. The first character shall be neither 
zero nor K, M or G.
    (2) Necessary bandwidths:

between 0.001 and 999 Hz shall be expressed in Hz (letter H);
between 1.00 and 999 kHz shall be expressed in kHz (letter K);
between 1.00 and 999 MHz shall be expressed in MHz (letter M);
between 1.00 and 999 GHz shall be expressed in GHz (letter G).

    (3) Examples:

0.002 Hz--H002
0.1 Hz--H100
25.3 Hz--25H3
400 Hz--400H
2.4 kHz--2K40
6 kHz--6K00
12.5 kHz--12K5
180.4 kHz--180K
180.5 kHz--181K
180.7 kHz--181K
1.25 MHz--1M25
2 MHz--2M00
10 MHz--10M0
202 MHz--202M
5.65 GHz--5G65

    (c) The necessary bandwidth may be determined by one of the 
following methods:
    (1) Use of the formulas included in the table, in paragraph (g) of 
this section, which also gives examples of necessary bandwidths and 
designation of corresponding emissions;
    (2) For frequency modulated radio systems which have a substantially 
linear relationship between the value of input voltage to the modulator 
and the resulting frequency deviation of the carrier and which carry 
either single sideband suppressed carrier frequency division multiplex 
speech channels or television, computation in accordance with provisions 
of paragraph (f) of this section and formulas and methods indicated in 
the table, in paragraph (g) of this section;
    (3) Computation in accordance with Recommendations of the 
International Radio Consultative Committee (C.C.I.R.);
    (4) Measurement in cases not covered by paragraph (c) (1), (2), or 
(3) of this section.
    (d) The value so determined should be used when the full designation 
of an emission is required. However, the necessary bandwidth so 
determined is not the only characteristic of an emission to be 
considered in evaluating the interference that may be caused by that 
emission.
    (e) In the formulation of the table in paragraph (g) of this 
section, the following terms are employed:

Bn = Necessary bandwidth in hertz
B = Modulation rate in bauds
N = Maximum possible number of black plus white elements to be 
transmitted per second, in facsimile
M = Maximum modulation frequency in hertz

    (f) Determination of values of D and Bn for systems 
specified in paragraph (c)(2) of this section:
    (1) Determination of D in systems for multichannel telephony:
    (i) The rms value of the per-channel deviation for the system shall 
be specified. (In the case of systems employing preemphasis or phase 
modulation, this value of per-channel deviation shall be specified at 
the characteristic baseband frequency.)
    (ii) The value of D is then calculated by multiplying the rms value 
of the per-channel deviation by the appropriate factors, as follows:

Where X represents the average power in a message circuit in dBmO; Nc is the number of circuits in the
  multiplexed message load; 3.76 corresponds to a peak load factor of 11.5 dB.

    (2) The necessary bandwidth (Bn) normally is considered 
to be numerically equal to:
    (i) 2M+2DK, for systems having no continuity pilot subcarrier or 
having a continuity pilot subcarrier whose frequency is not the highest 
modulating the main carrier;
    (ii) 2P+2DK, for systems having a continuity pilot subcarrier whose 
frequency exceeds that of any other signal modulating the main carrier, 
unless the conditions set forth in paragraph (f)(3) of this section are 
met.
    (3) As an exception to paragraph (f)(2)(ii) of this section, the 
necessary bandwidth (Bn) for such systems is numerically 
equal to 2P or 2M+2DK, whichever is greater, provided the following 
conditions are met:
    (i) The modulation index of the main carrier due to the continuity 
pilot subcarrier does not exceed 0.25, and
    (ii) In a radio system of multichannel telephony, the rms frequency 
deviation of the main carrier due to the continuity pilot subcarrier 
does not exceed 70 percent of the rms value of the per-channel 
deviation, or, in a radio system for television, the rms deviation of 
the main carrier due to the pilot does not exceed 3.55 percent of the 
peak deviation of the main carrier.

       Subpart E_Distress, Disaster, and Emergency Communications



Sec. 2.401  Distress messages.

    Each station licensee shall give absolute priority to radio 
communications or signals relating to ships or aircraft in distress; 
shall cease all sending on frequencies which will interfere with hearing 
a radiocommunication or signal of distress and except when engaged in 
answering or aiding the ship or aircraft in distress, shall refrain from 
sending any radio communications or signals until there is assurance 
that no interference will be caused with the radio communications or 
signals relating thereto; and shall assist the ship or aircraft in 
distress, so far as possible, by complying with its instructions.



Sec. 2.402  Control of distress traffic.

    The control of distress traffic is the responsibility of the mobile 
station in distress or of the mobile station which, by the application 
of the provisions of Sec. 2.403, has sent the distress call. These 
stations may, however, delegate the control of the distress traffic to 
another station.



Sec. 2.403  Retransmission of distress message.

    Any station which becomes aware that a mobile station is in distress 
may transmit the distress message in the following cases:
    (a) When the station in distress is not itself in a position to 
transmit the message.
    (b) In the case of mobile stations, when the master or the person in 
charge of the ship, aircraft, or other vehicles carrying the station 
which intervenes believes that further help is necessary.
    (c) In the case of other stations, when directed to do so by the 
station in control of distress traffic or when it has reason to believe 
that a distress call which it has intercepted has not been received by 
any station in a position to render aid.



Sec. 2.404  Resumption of operation after distress.

    No station having been notified to cease operation shall resume 
operation on frequency or frequencies which may cause interference until 
notified by the station issuing the original notice that the station 
involved will not interfere with distress traffic as it is then being 
routed or until the receipt of a general notice that the need for 
handling distress traffic no longer exists.



Sec. 2.405  Operation during emergency.

    The licensee of any station (except amateur, standard broadcast, FM 
broadcast, noncommercial educational FM broadcast, or television 
broadcast)

[[Page 634]]

may, during a period of emergency in which normal communication 
facilities are disrupted as a result of hurricane, flood, earthquake, or 
similar disaster, utilize such station for emergency communication 
service in communicating in a manner other than that specified in the 
instrument of authorization: Provided:
    (a) That as soon as possible after the beginning of such emergency 
use, notice be sent to the Commission at Washington, D.C., and to the 
Engineer in Charge of the district in which the station is located, 
stating the nature of the emergency and the use to which the station is 
being put, and
    (b) That the emergency use of the station shall be discontinued as 
soon as substantially normal communication facilities are again 
available, and
    (c) That the Commission at Washington, D.C., and the Engineer in 
Charge shall be notified immediately when such special use of the 
station is terminated: Provided further,
    (d) That in no event shall any station engage in emergency 
transmission on frequencies other than, or with power in excess of, that 
specified in the instrument of authorization or as otherwise expressly 
provided by the Commission, or by law: And provided further,
    (e) That any such emergency communication undertaken under this 
section shall terminate upon order of the Commission.

    Note: Part 73 of this chapter contains provisions governing 
emergency operation of standard, FM, noncommercial educational FM, and 
television broadcast stations. Part 97 of this chapter contains such 
provisions for amateur stations.

Sec. 2.406  National defense; free service.

    Any common carrier subject to the Communications Act may render to 
any agency of the United States Government free service in connection 
with the preparation for the national defense. Every such carrier 
rendering any such free service shall make and file, in duplicate, with 
the Commission, on or before the 31st day of July and on or before the 
31st day of January in each year, reports covering the periods of 6 
months ending on the 30th day of June and the 31st day of December, 
respectively, next prior to said dates. These reports shall show the 
names of the agencies to which free service was rendered pursuant to 
this rule, the general character of the communications handled for each 
agency, and the charges in dollars which would have accrued to the 
carrier for such service rendered to each agency if charges for all such 
communications had been collected at the published tariff rates.



Sec. 2.407  National defense; emergency authorization.

    The Federal Communications Commission may authorize the licensee of 
any radio station during a period of national emergency to operate its 
facilities upon such frequencies, with such power and points of 
communication, and in such a manner beyond that specified in the station 
license as may be requested by the Army, Navy, or Air Force.

Subparts F-G [Reserved]



               Subpart H_Prohibition Against Eavesdropping



Sec. 2.701  Prohibition against use of a radio device for eavesdropping.

    (a) No person shall use, either directly or indirectly, a device 
required to be licensed by section 301 of the Communications Act of 
1934, as amended, for the purpose of overhearing or recording the 
private conversations of others unless such use is authorized by all of 
the parties engaging in the conversation.

installation, provided that the purchase or lease agreement includes a 
proviso that such a determination of compliance be made and is the 
responsibility of the party responsible for verification of the 
equipment. If the purchase or lease agreement contains this proviso and 
the responsible party has the product measured to ensure compliance at 
the end user's location, the product does not need to be labelled with 
the statement in paragraph (c) of this section.
    (g) The provisions in paragraphs (b) through (f) of this section 
apply only to devices that are designed to comply with, and to the best 
of the responsible party's knowledge will, upon testing, comply with all 
applicable requirements in this chapter. The provisions in paragraphs 
(b) through (f) of this section do not apply to radio frequency devices 
that could not be authorized or legally operated under the current 
rules. Such devices shall not be operated, advertised, displayed, 
offered for sale or lease, sold or leased, or otherwise marketed absent

of type acceptance.

    Note: For the purposes of this part, an amplifier will be deemed 
incapable of operation below 144 MHz if the amplifier is not capable of 
being easily modified to increase its amplification characteristics 
below 120 MHz, and either:
    (1) The mean output power of the amplifier decreases, as frequency 
decreases from 144 MHz, to a point where 0 decibels or less gain is 
exhibited at 120 MHz and below 120 MHz; or
    (2) The amplifier is not capable of even short periods of operation 
below 120 MHz without sustaining permanent damage to its amplification 
circuitry.

    (d) The proscription in paragraph (b) of this section shall not 
apply to the marketing, as defined in paragraph (b) of this section, by

2.915(a), it will deny the application. Notification to the applicant 
will include a statement of the reasons for the denial.

[[Page 642]]



Sec. 2.921  Hearing on application.

    Whenever it is determined that an application for equipment 
authorization presents substantial factual questions relating to the 
qualifications of the applicant or the equipment (or the effects of the 
use thereof), the Commission may designate the application for hearing. 
A hearing on an application for an equipment authorization shall be 
conducted in the same manner as a hearing on a radio station application 
as set out in subpart B of part 1 of this chapter.



Sec. 2.923  Petition for reconsideration; application for review.

    Persons aggrieved by virtue of an equipment authorization action may 
file with the Commission a petition for reconsideration or an 
application for review. Rules governing the filing of petitions for 
reconsideration and applications for review are set forth in Sec. Sec. 
1.106 and 1.115, respectively, of this chapter.



Sec. 2.924  Marketing of electrically identical equipment having multiple 
trade names and models or type numbers under the same FCC Identifier.

    The grantee of an equipment authorization may market devices having 
different model/type numbers or trade names without additional 
authorization from the Commission, provided that such devices are 
electrically identical and the equipment bears an FCC Identifier 
validated by a grant of equipment authorization. A device will be 
considered to be electrically identical if no changes are made to the 
device authorized by the Commission, or if the changes made to the 
device would be treated as class I permissive changes within the scope 
of Sec. 2.1043(b)(1). Changes to the model number or trade name by 
anyone other than the grantee, or under the authorization of the 
grantee, shall be performed following the procedures in Sec. 2.933.

[62 FR 10470, Mar. 7, 1997, as amended at 63 FR 36598, July 7, 1998]



Sec. 2.925  Identification of equipment.

    (a) Each equipment covered in an application for equipment 
authorization shall bear a nameplate or label listing the following:
    (1) FCC Identifier consisting of the two elements in the exact order 
specified in Sec. 2.926. The FCC Identifier shall be preceded by the 
term FCC ID in capital letters on a single line, and shall be of a type 
size large enough to be legible without the aid of magnification.

    Example: FCC ID XXX123. XXX--Grantee Code 123--Equipment Product 
Code

    (2) Any other statements or labeling requirements imposed by the 
rules governing the operation of the specific class of equipment, except 
that such statement(s) of compliance may appear on a separate label at 
the option of the applicant/grantee.
    (3) Equipment subject only to registration will be identified 
pursuant to part 68 of this chapter.
    (b) Any device subject to more than one equipment authorization 
procedure may be assigned a single FCC Identifier. However, a single FCC 
Identifier is required to be assigned to any device consisting of two or 
more sections assembled in a common enclosure, on a common chassis or 
circuit board, and with common frequency controlling circuits. Devices 
to which a single FCC Identifier has been assigned shall be identified 
pursuant to paragraph (a) of this section.
    (1) Separate FCC Identifiers may be assigned to a device consisting 
of two or more sections assembled in a common enclosure, but constructed 
on separate sub-units or circuit boards with independent frequency 
controlling circuits. The FCC Identifier assigned to any transmitter 
section shall be preceded by the term TX FCC ID, the FCC Identifier 
assigned to any receiver section shall be preceded by the term RX FCC ID 
and the identifier assigned to any remaining section(s) shall be 
preceded by the term FCC ID.
    (2) Where telephone equipment subject to part 68 of this chapter, 
and a radiofrequency device subject to equipment authorization 
requirements are assembled in a common enclosure, the nameplate/label 
shall display the FCC Registration Number in the format specified in 
part 68 and the FCC Identifier in the format specified in paragraph (a) 
of this section.

[[Page 643]]

    (3) Applications filed on or after May 1, 1981, and applications 
filed earlier requesting equipment authorization using the single system 
of identification pursuant to section (a)(1) will receive a review of 
the identification portion by the Commission's Laboratory with respect 
to nameplate/label design within 30 days after receipt at the 
Laboratory. Failure by the Laboratory to reject a nameplate design 
proposed in any particular application within this time period will 
constitute de-facto acceptance of the nameplate/label design for that 
particular equipment. Such de facto acceptance will be limited to the 
equipment covered by the particular application and will not be 
considered to establish a precedent for other applications. This review 
deadline applies only to the proposed nameplate/label design, not to the 
remainder of the application.
    (4) For a transceiver, the receiver portion of which is subject to 
verification pursuant to Sec. 15.101 of this chapter, the FCC 
Identifier required for the transmitter portion shall be preceded by the 
term FCC ID.
    (c) [Reserved]
    (d) In order to validate the grant of equipment authorization, the 
nameplate or label shall be permanently affixed to the equipment and 
shall be readily visible to the purchaser at the time of purchase.
    (1) As used here, permanently affixed means that the required 
nameplate data is etched, engraved, stamped, indelibly printed, or 
otherwise permanently marked on a permanently attached part of the 
equipment enclosure. Alternatively, the required information may be 
permanently marked on a nameplate of metal, plastic, or other material 
fastened to the equipment enclosure by welding, riveting, etc., or with 
a permanent adhesive. Such a nameplate must be able to last the expected 
lifetime of the equipment in the environment in which the equipment will 
be operated and must not be readily detachable.
    (2) As used here, readily visible means that the nameplate or 
nameplate data must be visible from the outside of the equipment 
enclosure. It is preferable that it be visible at all times during 
normal installation or use, but this is not a prerequisite for grant of 
equipment authorization.
    (e) A software defined radio may be equipped with a means such as a 
user display screen to display the FCC identification number normally 
contained in the nameplate or label. The information must be readily 
accessible, and the user manual must describe how to access the 
electronic display.
    (f) Where it is shown that a permanently affixed nameplate is not 
desirable or is not feasible, an alternative method of positively 
identifying the equipment may be used if approved by the Commission. The 
proposed alternative method of identification and the justification for 
its use must be included with the application for equipment 
authorization.

    Note: As an example, a device intended to be implanted within the 
body of a test animal or person would probably require an alternate 
method of identification.

    (g) The term FCC ID and the coded identification assigned by the 
Commission shall be in a size of type large enough to be readily 
legible, consistent with the dimensions of the equipment and its 
nameplate. However, the type size for the FCC Identifier is not required 
to be larger than eight-point.

Sec. 2.926  FCC identifier.

    (a) A grant of equipment authorization issued by the Commission will 
list the validated FCC Identifier consisting of the grantee code 
assigned by the FCC pursuant to paragraph (b) of this section, and the 
equipment product code assigned by the grantee pursuant to paragraph (c) 
of this section. See Sec. 2.925.
    (b) The grantee code assigned pursuant to paragraph (c) of this 
section is assigned permanently to applicants/grantees and is valid only 
for the party specified as the applicant/grantee in the code 
assignment(s).
    (c) A grantee code will have three characters consisting of Arabic 
numerals, capital letters, or combination thereof. A prospective grantee 
or his authorized representative may submit

[[Page 644]]

a written request to the Commission for assignment of a grantee code at 
any time. However, it is preferred that grantee codes be requested prior 
to filing applications for equipment authorization. If a grantee code is 
not requested in advance, one will be assigned at the time an 
application is received by the FCC Laboratory and the applicant will be 
notified to make any necessary label revisions in order to comply fully 
with application procedural rules.
    (1) After assignment of a grantee code each grantee will continue to 
use the same grantee code for subsequent equipment authorization 
applications.
    In the event the grantee name is changed or ownership is 
transferred, the circumstances shall be reported to the Commission so 
that a new grantee code can be assigned, if appropriate. See Sec. Sec. 
2.934 and 2.935 for additional information.
    (2) [Reserved]
    (d) The equipment product code assigned by the grantee shall consist 
of a series of Arabic numerals, capital letters or a combination 
thereof, and may include the dash or hyphen (-). The total of Arabic 
numerals, capital letters and dashes or hyphens shall not exceed 14 and 
shall be one which has not been previously used in conjunction with:
    (1) The same grantee code, or
    (2) An application denied pursuant to Sec. 2.919 of this chapter.
    (e) No FCC Identifier may be used on equipment to be marketed unless 
that specific identifier has been validated by a grant of equipment 
authorization issued by the Commission. This shall not prohibit 
placement of an FCC identifier on a transceiver which includes a 
verified receiver subject to Sec. 15.101, provided that the transmitter 
portion of such transceiver is covered by a valid grant of type 
acceptance or certification. The FCC Identifier is uniquely assigned to 
the grantee and may not be placed on the equipment without authorization 
by the grantee. See Sec. 2.803 for conditions applicable to the display 
at trade shows of equipment which has not been granted equipment 
authorization where such grant is required prior to marketing. Labelling 
of such equipment may include model or type numbers, but shall not 
include a purported FCC Identifier.

    (1) A record of the original design drawings and specifications and 
all changes that have been made that may affect compliance with the 
standards and the requirements of Sec. 2.931.
    (2) A record of the procedures used for production inspection and 
testing to ensure conformance with the standards and the requirements of 
Sec. 2.931.
    (3) A record of the test results that demonstrate compliance with 
the appropriate regulations in this chapter.
    (b) The provisions of paragraph (a) of this section shall also apply 
to a manufacturer of equipment produced under the provisions of Sec. 
2.929(b). The retention of the records by the manufacturer under these 
circumstances shall satisfy the grantee's responsibility under paragraph 
(a) of this section.
    (c) The records listed in paragraph (a) of this section shall be 
retained for one year for equipment subject to authorization under the 
certification procedure or former type acceptance procedure, or for two 
years for equipment subject to authorization under any other procedure, 
after the manufacture of said equipment has been permanently 
discontinued, or until the conclusion of an investigation or a 
proceeding if the responsible party (or, under paragraph (b) of this 
section, the manufacturer) is officially notified that an investigation 
or any other administrative proceeding involving its equipment has been 
instituted.
    (d) If radio frequency equipment is modified by any party other than 
the original responsible party, and that party is not working under the 
authorization of the original responsible party, the party performing 
the modifications is not required to obtain the original design drawings 
specified in paragraph (a)(1) of this section. However, the party 
performing the modifications must maintain records showing the changes 
made to the equipment along with the records required in paragraphs 
(a)(3) of this section. A new equipment authorization may also be

    Authority: Sections 2.951 through 2.957 are issued under secs. 4, 
303, 307, 48 Stat., as amended, 1066, 1082, 1083; 47 U.S.C. 154, 303, 
307.

    Source: Sections 2.951 through 2.957 appear at 46 FR 23249, Apr. 24, 
1981, unless otherwise noted.



Sec. 2.951  Cross reference.

    The provisions of Sec. 2.901, et seq., shall apply to equipment 
subject to verification.



Sec. 2.952  Limitation on verification.

    (a) Verification signifies that the manufacturer or importer has 
determined that the equipment has been shown to be capable of compliance 
with the applicable technical standards if no unauthorized change is 
made in the equipment and if the equipment is properly maintained and 
operated. Compliance with these standards shall not be construed to be a 
finding by the manufacturer or importer with respect to matters not 
encompassed by the Commission's rules.
    (b) Verification of the equipment by the manufacturer or importer is 
effective until a termination date is otherwise established by the 
Commission.
    (c) No person shall, in any advertising matter, brochure, etc., use 
or make reference to a verification in a deceptive or misleading manner 
or convey the impression that such verification reflects more than a 
determination by the manufacturer or importer that the device or product 
has been shown to be capable of compliance with the applicable technical 
standards of the Commission's rules.



Sec. 2.953  Responsibility for compliance.

    (a) In verifying compliance, the responsible party, as defined in 
Sec. 2.909 warrants that each unit of equipment marketed under the 
verification procedure will be identical to the unit tested and found 
acceptable with the standards and that the records maintained by the 
responsible party continue to reflect the equipment being produced under 
such verification within the variation that can be expected due to 
quantity production and testing on a statistical basis.
    (b) The importer of equipment subject to verification may upon 
receiving a written statement from the manufacturer that the equipment 
complies with the appropriate technical standards rely on the 
manufacturer or independent testing agency to verify compliance. The 
test records required by Sec. 2.955 however should be in the English 
language and made available to the Commission upon a reasonable request, 
in accordance with Sec. 2.956.
    (c) In the case of transfer of control of equipment, as in the case 
of sale or merger of the grantee, the new manufacturer or importer shall 
bear the responsibility of continued compliance of the equipment.
    (d) Verified equipment shall be reverified if any modification or 
change adversely affects the emanation characteristics of the modified 
equipment. The party designated in Sec. 2.909 bears responsibility for 
continued compliance of subsequently produced equipment.

[[Page 653]]



Sec. 2.954  Identification.

    Devices subject only to verification shall be uniquely identified by 
the person responsible for marketing or importing the equipment within 
the United States. However, the identification shall not be of a format 
which could be confused with the FCC Identifier required on certified, 
notified or type accepted equipment. The importer or manufacturer shall 
maintain adequate identification records to facilitate positive 
identification for each verified device.

[62 FR 10472, Mar. 7, 1997]



Sec. 2.955  Retention of records.

    (a) For each equipment subject to verification, the responsible 
party, as shown in Sec. 2.909 shall maintain the records listed as 
follows:
    (1) A record of the original design drawings and specifications and 
all changes that have been made that may affect compliance with the 
requirements of Sec. 2.953.
    (2) A record of the procedures used for production inspection and 
testing (if tests were performed) to insure the conformance required by 
Sec. 2.953. (Statistical production line emission testing is not 
required.)
    (3) A record of the measurements made on an appropriate test site 
that demonstrates compliance with the applicable regulations in this 
chapter. The record shall:
    (i) Indicate the actual date all testing was performed;
    (ii) State the name of the test laboratory, company, or individual 
performing the verification testing. The Commission may request

assessment. The general competence, efficiency, experience, familiarity 
with technical regulations and products included in those technical 
regulations, as well as compliance with applicable parts of the ISO/IEC 
Guides 25 and 65, shall be taken into consideration.
    (5) A TCB shall participate in any consultative activities, 
identified by the Commission or NIST, to facilitate a common 
understanding and interpretation of applicable regulations.
    (6) The Commission will provide public notice of the specific 
methods that will be used to accredit TCBs, consistent with these 
qualification criteria.
    (d) Sub-contractors. (1) In accordance with the provisions of sub-
clause 4.4 of ISO/IEC Guide 65, the testing of a product, or a portion 
thereof, may be performed by a sub-contractor of a designated TCB, 
provided the laboratory has been assessed by the TCB as competent and in 
compliance with the applicable provisions of ISO/IEC Guide 65 and other 
relevant standards and guides.
    (2) When a subcontractor is used, the TCB shall be responsible for

electronic copy of each approved application form and grant of 
certification to the Commission.
    (2) In accordance with ISO/IEC Guide 65, a TCB is required to 
conduct appropriate post-market surveillance activities. These 
activities shall be based on type testing a few samples of the total 
number of product types which the certification body has certified. 
Other types of surveillance activities of a product that has been 
certified are permitted, provided they are no more onerous than testing 
type. The Commission may at any time request a list of products 
certified by the certification body and may request and receive copies 
of product evaluation reports. The Commission may also request that a 
TCB perform post-market surveillance, under Commission guidelines, of a 
specific product it has certified.

shall also be provided within thirty days of the action taken by the 
grantee to correct the situation.
    (4) Where concerns arise, the TCB shall provide a copy of the 
application file to the Commission within 30 calendar days of a request 
for the file made by the Commission to the TCB and the manufacturer. 
Where appropriate, the file should be accompanied by a request for 
confidentiality for any material that may qualify for confidential 
treatment under the Commission's Rules. If the application file is not 
provided within 30 calendar days, a statement shall be provided to the 
Commission as to why it cannot be provided.
    (h) In case of a dispute with respect to designation or recognition 
of a TCB and the testing or certification of products by a TCB, the 
Commission will be the final arbiter. Manufacturers and designated TCBs 
will be afforded at least 30 days to comment before a decision is 
reached. In the case of a TCB designated or recognized, or a product 
certified pursuant to an effective bilateral or multilateral mutual 
recognition agreement or arrangement (MRA) to which the United States is 
a party, the Commission may limit or withdraw its recognition of a TCB 
designated by an MRA party and revoke the certification of products 
using testing or certification provided by such a TCB. The Commission 
shall consult with the Office of the United States Trade Representative 
(USTR), as necessary, concerning any disputes arising under an MRA for 
compliance with the Telecommunications Trade Act of 1988 (Section 1371-
1382 of the Omnibus Trade and Competitiveness Act of 1988).

Sec. 2.1035  [Reserved]



Sec. 2.1041  Measurement procedure.

    For equipment operating under parts 15 and 18, the measurement 
procedures are specified in the rules governing the particular device 
for which certification is requested. For equipment operating in the 
authorized radio services, measurements are required as specified in 
Sec. Sec. 2.1046, 2.1047, 2.1049, 2.1051, 2.1053, 2.1055 and 2.1057. 
See also Sec. 2.947.

[63 FR 36600, July 7, 1998]



Sec. 2.1043  Changes in certificated equipment.

    (a) Except as provided in paragraph (b)(3) of this section, changes 
to the basic frequency determining and stabilizing circuitry (including 
clock or data rates), frequency multiplication stages, basic modulator 
circuit or maximum power or field strength ratings shall not be 
performed without application for and authorization of a new grant of 
certification. Variations in electrical or mechanical construction, 
other than these indicated items, are permitted provided the variations 
either do not affect the characteristics required to be reported to the 
Commission or the variations are made in compliance with the other 
provisions of this section. Changes to the software installed in a 
transmitter that do not affect the radio frequency emissions do not 
require a filing with the Commission and may be made by parties other 
than the holder of the grant of certification.
    (b) Three classes of permissive changes may be made in certificated 
equipment without requiring a new application for and grant of 
certification. None of the classes of changes shall result in a change 
in identification.
    (1) A Class I permissive change includes those modifications in the 
equipment which do not degrade the characteristics reported by the 
manufacturer and accepted by the Commission when certification is 
granted. No filing with the Commission is required for a Class I 
permissive change.
    (2) A Class II permissive change includes those modifications which 
degrade the performance characteristics as reported to the Commission at 
the

[[Page 660]]

time of the initial certification. Such degraded performance must still 
meet the minimum requirements of the applicable rules. When a Class II 
permissive change is made by the grantee, the grantee shall supply the 
Commission with complete information and the results of tests of the 
characteristics affected by such change. The modified equipment shall 
not be marketed under the existing grant of certification prior to 
acknowledgement by the Commission that the change is acceptable.
    (3) A Class III permissive change includes modifications to the 
software of a software defined radio transmitter that change the 
frequency, modulation type, output power or maximum field strength 
outside the parameters previously approved. When a Class III permissive 
change is made, the grantee shall supply the Commission with a 
description of the changes and test results showing that the equipment 
complies with the applicable rules with the new software loaded, 
including compliance with the applicable RF exposure requirements. The 
modified software shall not be loaded into equipment, and the equipment 
shall not be marketed with the modified software under the existing 
grant of certification, prior to acknowledgement by the Commission that 
the change is acceptable. A copy of the software shall be submitted to 
the Commission upon request. Class III changes are permitted only for 
equipment in which no Class II changes have been made from the 
originally approved device.
    Note to paragraph (b)(3):
    Any software change that degrades spurious and out-of-band emissions 
previously reported to the Commission at the time of initial 
certification would be considered a change in frequency or modulation 
and would require a Class III permissive change or new equipment 
authorization application.
    (4) Class I and Class II permissive changes may only be made by the 
holder of the grant of certification, except as specified below.
    (c) A grantee desiring to make a change other than a permissive 
change shall file an application on FCC Form 731 accompanied by the 
required fees. The grantee shall attach a description of the change(s) 
to be made and a statement indicating whether the change(s) will be made 
in all units (including previous production) or will be made only in 
those units produced after the change is authorized.
    (d) A modification which results in a change in the identification 
of a device with or without change in circuitry requires a new 
application for, and grant of certification. If the changes affect the 
characteristics required to be reported, a complete application shall be 
filed. If the characteristics required to be reported are not changed 
the abbreviated procedure of Sec. 2.933 may be used.
    (e) Equipment that has been certificated or formerly type accepted 
for use in the Amateur Radio Service pursuant to the requirements of 
part 97 of this chapter may be modified without regard to the conditions 
specified in paragraph (b) of this section, provided the following 
conditions are met:
    (1) Any person performing such modifications on equipment used under 
part 97 of this chapter must possess a valid amateur radio operator 
license of the class required for the use of the equipment being 
modified.
    (2) Modifications made pursuant to this paragraph are limited to 
equipment used at licensed amateur radio stations.
    (3) Modifications specified or performed by equipment manufacturers 
or suppliers must be in accordance with the requirements set forth in 
paragraph (b) of this section.
    (4) Modifications specified or performed by licensees in the Amateur 
Radio Service on equipment other than that at specific licensed amateur 
radio stations must be in accordance with the requirements set forth in 
paragraph (b) of this section.
    (5) The station licensee shall be responsible for ensuring that 
modified equipment used at his station will comply with the applicable 
technical standards in part 97 of this chapter.
    (f) For equipment other than that operating under parts 15 or 18, 
when a Class II permissive change is made by other than the grantee of 
certification, the information and data specified in paragraph (b)(2) of 
this section shall be supplied by the person making the change. The 
modified equipment shall not be operated under an authorization

[[Page 661]]

of the Commission prior to acknowledgement by the Commission that the 
change is acceptable.
    (g) The interconnection of a certificated or formerly type accepted 
AM broadcast stereophonic exciter-generator with a certificated or 
formerly type accepted AM broadcast transmitter in accordance with the 
manufacturer's instructions and upon completion of measurements showing 
that the modified transmitter meets the emission limitation requirements 
of Sec. 73.44 is defined as a Class I permissive change for compliance 
with this section.
    (h) The interconnection of a multiplexing exciter with a 
certificated or formerly type accepted AM broadcast transmitter in 
accordance with the manufacturer's instructions without electrical or 
mechanical modification of the transmitter circuits and completion of 
equipment performance measurements showing the transmitter meets the 
minimum performance requirements applicable thereto is defined as a 
Class I permissive change for compliance with this section.
    (i) The addition of TV broadcast subcarrier generators to a 
certificated or formerly type accepted TV broadcast transmitter or the 
addition of FM broadcast subcarrier generators to a type accepted FM 
broadcast transmitter, provided the transmitter exciter is designed for 
subcarrier operation without mechanical or electrical alterations to the 
exciter or other transmitter circuits.
    (j) The addition of TV broadcast stereophonic generators to a 
certificated or formerly type accepted TV broadcast transmitter or the 
addition of FM broadcast stereophonic generators to a certificated or 
formerly type accepted FM broadcast transmitter, provided the 
transmitter exciter is designed for stereophonic sound operation without 
mechanical or electrical alterations to the exciter or other transmitter 
circuits.
    (k) The addition of subscription TV encoding equipment for which the 
FCC has granted advance approval under the provisions of Sec. 2.1400 in 
subpart M and Sec. 73.644(c) of part 73 to a certificated or formerly 
type accepted transmitter is considered a Class I permissive change.
    (l) Notwithstanding the provisions of this section, broadcast 
licensees or permittees are permitted to modify certificated or formerly 
type accepted equipment pursuant to Sec. 73.1690 of the FCC's rules.

applied simultaneously. The input levels of the tones shall be so 
adjusted that the two principal frequency components of the radio 
frequency signal produced are equal in magnitude.
    (3) Single sideband transmitters in the A3H emission mode--when

produce a radio frequency signal component equal in magnitude to the 
magnitude of the carrier in this mode.
    (4) As an alternative to paragraphs (d) (2) and (3) of this section, 
other tones besides those specified may be used as modulating 
frequencies, upon a sufficient showing of need. However any tones so 
chosen must not be harmonically related, the third and fifth order 
intermodulation products which occur must fall within the -25 dB step of

Sec. 2.1051  Measurements required: Spurious emissions at antenna terminals.

    The radio frequency voltage or powers generated within the equipment 
and appearing on a spurious frequency shall be checked at the equipment 
output terminals when properly loaded with a suitable artificial 
antenna. Curves or equivalent data shall show the magnitude of each

Sec. 2.1053  Measurements required: Field strength of spurious radiation.

    (a) Measurements shall be made to detect spurious emissions that may 
be radiated directly from the cabinet, control circuits, power leads, or 
intermediate circuit elements under normal conditions of installation 
and operation. Curves or equivalent data shall be supplied showing the 
magnitude of each harmonic and other spurious emission. For this test, 
single sideband, independent sideband, and controlled carrier 
transmitters shall be modulated under the conditions specified in 
paragraph (c) of Sec. 2.1049, as appropriate. For equipment operating 
on frequencies below 890 MHz, an open field test is normally required, 
with the measuring instrument antenna located in the far-field at all 
test frequencies. In the event it is either impractical or impossible to 
make open field measurements (e.g. a broadcast transmitter installed in 
a building) measurements will be accepted of the equipment as installed. 
Such measurements must be accompanied by a description of the site where 
the measurements were made showing the location of any possible source 
of reflections which might distort the field strength measurements. 
Information submitted shall include the relative radiated power of each 
spurious emission with reference to the rated power output of the 
transmitter, assuming all emissions are radiated from halfwave dipole 
antennas.
    (b) The measurements specified in paragraph (a) of this section 
shall be made for the following equipment:
    (1) Those in which the spurious emissions are required to be 60 dB 
or more below the mean power of the transmitter.

for use in the Radio Broadcast Services under part 73 of this chapter.
    (b) Frequency measurements shall be made at the extremes of the 
specified temperature range and at intervals of not more than 10[deg] 
centigrade through the range. A period of time sufficient to stabilize 
all of the components of the oscillator circuit at each temperature 
level shall be allowed prior to frequency measurement. The short term 
transient effects on the frequency of the transmitter due to keying 
(except for broadcast transmitters) and any heating element cycling 
normally occurring at each ambient temperature level also shall be 
shown. Only the portion or portions of the transmitter containing the 
frequency determining and stabilizing circuitry need be subjected to the 
temperature variation test.
    (c) In addition to all other requirements of this section, the 
following information is required for equipment incorporating heater 
type crystal oscillators to be used in mobile stations, for which type 
acceptance is first requested after March 25, 1974, except for battery 
powered, hand carried, portable equipment having less than 3 watts mean 
output power.
    (1) Measurement data showing variation in transmitter output 
frequency from a cold start and the elapsed time necessary for the 
frequency to stabilize within the applicable tolerance. Tests shall be 
made after temperature stabilization at each of the ambient temperature 
levels; the lower temperature limit, 0[deg] centigrade and +30[deg] 
centigrade with no primary power applied.
    (2) Beginning at each temperature level specified in paragraph 
(c)(1) of this section, the frequency shall be measured within one 
minute after application of primary power to the transmitter and at 
intervals of no more than one minute thereafter until ten minutes have 
elapsed or until sufficient measurements are obtained to indicate 
clearly that the frequency has stabilized within the applicable 
tolerance, whichever time period is greater. During each test, the 
ambient temperature shall not be allowed to rise more than 10[deg] 
centigrade above the respective beginning ambient temperature level.
    (3) The elapsed time necessary for the frequency to stabilize within 
the applicable tolerance from each beginning ambient temperature level 
as determined from the tests specified in this paragraph shall be 
specified in the instruction book for the transmitter furnished to the 
user.
    (4) When it is impracticable to subject the complete transmitter to 
this test because of its physical dimensions or power rating, only its 
frequency determining and stabilizing portions need be tested.
    (d) The frequency stability shall be measured with variation of 
primary supply voltage as follows:
    (1) Vary primary supply voltage from 85 to 115 percent of the 
nominal value for other than hand carried battery equipment.
    (2) For hand carried, battery powered equipment, reduce primary 
supply voltage to the battery operating end point which shall be 
specified by the manufacturer.

[[Page 667]]

    (3) The supply voltage shall be measured at the input to the cable 
normally provided with the equipment, or at the power supply terminals 
if cables are not normally provided. Effects on frequency of transmitter 
keying (except for broadcast transmitters) and any heating element 
cycling at the nominal supply voltage and at each extreme also shall be 
shown.
    (e) When deemed necessary, the Commission may require tests of 
frequency stability under conditions in addition to those specifically 
set out in paragraphs (a), (b), (c), and (d) of this section. (For 
example measurements showing the effect of proximity to large metal 
objects, or of various types of antennas, may be required for portable 
equipment.)

Sec. 2.1057  Frequency spectrum to be investigated.

    (a) In all of the measurements set forth in Sec. Sec. 2.1051 and 
2.1053, the spectrum shall be investigated from the lowest radio 
frequency signal generated in the equipment, without going below 9 kHz, 
up to at least the frequency shown below:
    (1) If the equipment operates below 10 GHz: to the tenth harmonic of 
the highest fundamental frequency or to 40 GHz, whichever is lower.
    (2) If the equipment operates at or above 10 GHz and below 30 GHz: 
to the fifth harmonic of the highest fundamental frequency or to 100 
GHz, whichever is lower.
    (3) If the equipment operates at or above 30 GHz: to the fifth 
harmonic of the highest fundamental frequency or to 200 GHz, whichever 
is lower.
    (b) Particular attention should be paid to harmonics and 
subharmonics of the carrier frequency as well as to those frequencies 
removed from the carrier by multiples of the oscillator frequency. 
Radiation at the frequencies of multiplier stages should also be 
checked.
    (c) The amplitude of spurious emissions which are attenuated more 
than 20 dB below the permissible value need not be reported.
    (d) Unless otherwise specified, measurements above 40 GHz shall be 
performed using a minimum resolution bandwidth of 1 MHz.

                    Radiofrequency Radiation Exposure



Sec. 2.1091  Radiofrequency radiation exposure evaluation: mobile devices.

    (a) Requirements of this section are a consequence of Commission 
responsibilities under the National Environmental Policy Act to evaluate 
the environmental significance of its actions. See subpart I of part 1 
of this chapter, in particular Sec. 1.1307(b).
    (b) For purposes of this section, a mobile device is defined as a 
transmitting device designed to be used in other than fixed locations 
and to generally be used in such a way that a separation distance of at 
least 20 centimeters is normally maintained between the transmitter's 
radiating structure(s) and the body of the user or nearby persons. In 
this context, the term ``fixed location'' means that the device is 
physically secured at one location and is not able to be easily moved to 
another location. Transmitting devices designed to be used by consumers 
or workers that can be easily re-located, such as wireless devices 
associated with a personal computer, are considered to be mobile devices 
if they meet the 20 centimeter separation requirement.
    (c) Mobile devices that operate in the Cellular Radiotelephone 
Service, the Personal Communications Services, the Satellite 
Communications Services, the General Wireless Communications Service, 
the Wireless Communications Service, the Maritime Services and the 
Specialized Mobile Radio Service authorized under subpart H of part 22 
of this chapter, parts 24, 25, 26 and 27 of this chapter, part 80 of 
this chapter (ship earth stations devices only) and part 90 of this 
chapter are subject to routine environmental evaluation for RF exposure 
prior to equipment authorization or use if they operate at frequencies 
of 1.5 GHz or below and their effective radiated power (ERP) is 1.5 
watts or more, or if they operate at frequencies above 1.5 GHz and their 
ERP is 3 watts or more. Unlicensed personal communications service 
devices, unlicensed millimeter wave devices and unlicensed NII devices 
authorized under Sec. Sec. 15.253, 15.255, and 15.257, and subparts D 
and E of part 15 of this chapter are also subject to routine 
environmental evaluation for RF exposure prior to equipment 
authorization or use if their ERP is 3 watts or more or if they meet the 
definition of a portable device as specified in Sec. 2.1093(b) 
requiring evaluation under the provisions of that section. All other 
mobile and unlicensed transmitting devices are categorically excluded 
from routine environmental evaluation for RF exposure prior to equipment 
authorization or use, except as specified in Sec. Sec. 1.1307(c) and 
1.1307(d) of this chapter. Applications for equipment authorization of 
mobile and unlicensed transmitting devices subject to routine 
environmental evaluation must contain a statement confirming compliance 
with the limits specified in paragraph (d) of this section as part of 
their application. Technical information showing the basis for this 
statement must be submitted to the Commission upon request.
    (d) The limits to be used for evaluation are specified in Sec. 
1.1310 of this chapter. All unlicensed personal communications service 
(PCS) devices and unlicensed NII devices shall be subject to the limits 
for general population/uncontrolled exposure.
    (1) For purposes of analyzing mobile transmitting devices under the 
occupational/controlled criteria specified in Sec. 1.1310 of this 
chapter, time-averaging provisions of the guidelines may be used in 
conjunction with typical maximum duty factors to determine maximum 
likely exposure levels.
    (2) Time-averaging provisions may not be used in determining typical 
exposure levels for devices intended for use by consumers in general 
population/uncontrolled environments as defined in Sec. 1.1310 of this 
chapter. However, ``source-based'' time-averaging

[[Page 672]]

based on an inherent property or duty-cycle of a device is allowed. An 
example of this is the determination of exposure from a device that uses 
digital technology such as a time-division multiple-access (TDMA) scheme 
for transmission of a signal. In general, maximum average power levels 
must be used to determine compliance.
    (3) If appropriate, compliance with exposure guidelines for devices 
in this section can be accomplished by the use of warning labels and by 
providing users with information concerning minimum separation distances 
from transmitting structures and proper installation of antennas.
    (4) In some cases, e.g., modular or desktop transmitters, the 
potential conditions of use of a device may not allow easy 
classification of that device as either mobile or portable (also see 
Sec. 2.1093). In such cases, applicants are responsible for determining 
minimum distances for compliance for the intended use and installation 
of the device based on evaluation of either specific absorption rate 
(SAR), field strength or power density, whichever is most appropriate.

30, 2003; 69 FR 3264, Jan. 23, 2004]



Sec. 2.1093  Radiofrequency radiation exposure evaluation: portable devices.

    (a) Requirements of this section are a consequence of Commission 
responsibilities under the National Environmental Policy Act to evaluate 
the environmental significance of its actions. See subpart I of part 1 
of this chapter, in particular Sec. 1.1307(b).
    (b) For purposes of this section, a portable device is defined as a 
transmitting device designed to be used so that the radiating 
structure(s) of the device is/are within 20 centimeters of the body of 
the user.
    (c) Portable devices that operate in the Cellular Radiotelephone 
Service, the Personal Communications Service (PCS), the Satellite 
Communications Services, the General Wireless Communications Service, 
the Wireless Communications Service, the Maritime Services, the 
Specialized Mobile Radio Service, the 4.9 GHz Band Service, the Wireless 
Medical Telemetry Service (WMTS) and the Medical Implant Communications 
Service (MICS), authorized under subpart H of part 22 of this chapter, 
parts 24, 25, 26, 27, 80 and 90 of this chapter, subparts H and I of 
part 95 of this chapter, and unlicensed personal communication service, 
unlicensed NII devices and millimeter wave devices authorized under 
subparts D and E, Sec. Sec. 15.253, 15.255 and 15.257 of this chapter 
are subject to routine environmental evaluation for RF exposure prior to 
equipment authorization or use. All other portable transmitting devices 
are categorically excluded from routine environmental evaluation for RF 
exposure prior to equipment authorization or use, except as specified in 
Sec. Sec. 1.1307(c) and 1.1307(d) of this chapter. Applications for 
equipment authorization of portable transmitting devices subject to 
routine environmental evaluation must contain a statement confirming 
compliance with the limits specified in paragraph (d) of this section as 
part of their application. Technical information showing the basis for 
this statement must be submitted to the Commission upon request.
    (d) The limits to be used for evaluation are based generally on 
criteria published by the American National Standards Institute (ANSI) 
for localized specific absorption rate (``SAR'') in Section 4.2 of 
``IEEE Standard for Safety Levels with Respect to Human Exposure to 
Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz,'' ANSI/IEEE 
C95.1-1992, Copyright 1992 by the Institute of Electrical and 
Electronics Engineers, Inc., New York, New York 10017. These criteria 
for SAR evaluation are similar to those recommended by the National 
Council on Radiation Protection and Measurements (NCRP) in ``Biological 
Effects and Exposure Criteria for Radiofrequency Electromagnetic 
Fields,'' NCRP Report No. 86, Section 17.4.5. Copyright NCRP, 1986, 
Bethesda, Maryland 20814. SAR is a measure of the rate of energy 
absorption due to exposure to an RF transmitting source. SAR values have 
been related to threshold levels for potential biological hazards. The 
criteria to be used are specified in paragraphs (d)(1) and (d)(2)

[[Page 673]]

of this section and shall apply for portable devices transmitting in the 
frequency range from 100 kHz to 6 GHz. Portable devices that transmit at 
frequencies above 6 GHz are to be evaluated in terms of the MPE limits 
specified in Sec. 1.1310 of this chapter. Measurements and calculations 
to demonstrate compliance with MPE field strength or power density 
limits for devices operating above 6 GHz should be made at a minimum 
distance of 5 cm from the radiating source.
    (1) Limits for Occupational/Controlled exposure: 0.4 W/kg as 
averaged over the whole-body and spatial peak SAR not exceeding 8 W/kg 
as averaged over any 1 gram of tissue (defined as a tissue volume in the 
shape of a cube). Exceptions are the hands, wrists, feet and ankles 
where the spatial peak SAR shall not exceed 20 W/kg, as averaged over an 
10 grams of tissue (defined as a tissue volume in the shape of a cube). 
Occupational/Controlled limits apply when persons are exposed as a 
consequence of their employment provided these persons are fully aware 
of and exercise control over their exposure. Awareness of exposure can 
be accomplished by use of warning labels or by specific training or 
education through appropriate means, such as an RF safety program in a 
work environment.
    (2) Limits for General Population/Uncontrolled exposure: 0.08 W/kg 
as averaged over the whole-body and spatial peak SAR not exceeding 1.6 
W/kg as averaged over any 1 gram of tissue (defined as a tissue volume 
in the shape of a cube). Exceptions are the hands, wrists, feet and 
ankles where the spatial peak SAR shall not exceed 4 W/kg, as averaged 
over any 10 grams of tissue (defined as a tissue volume in the shape of 
a cube). General Population/Uncontrolled limits apply when the general 
public may be exposed, or when persons that are exposed as a consequence 
of their employment may not be fully aware of the potential for exposure 
or do not exercise control over their exposure. Warning labels placed on 
consumer devices such as cellular telephones will not be sufficient 
reason to allow these devices to be evaluated subject to limits for 
occupational/controlled exposure in paragraph (d)(1) of this section.
    (3) Compliance with SAR limits can be demonstrated by either 
laboratory measurement techniques or by computational modeling. 
Methodologies and references for SAR evaluation are described in 
numerous technical publications including ``IEEE Recommended Practice 
for the Measurement of Potentially Hazardous Electromagnetic Fields--RF 
and Microwave,'' IEEE C95.3-1991.
    (4) For purposes of analyzing portable transmitting devices under 
the occupational/controlled criteria, the time-averaging provisions of 
the MPE guidelines identified in Sec. 1.1310 of this chapter can be 
used in conjunction with typical maximum duty factors to determine 
maximum likely exposure levels.
    (5) Time-averaging provisions of the MPE guidelines identified in 
Sec. 1.1310 of this chapter may not be used in determining typical 
exposure levels for portable devices intended for use by consumers, such 
as hand-held cellular telephones, that are considered to operate in 
general population/uncontrolled environments as defined above. However, 
``source-based'' time-averaging based on an inherent property or duty-
cycle of a device is allowed. An example of this would be the 
determination of exposure from a device that uses digital technology 
such as a time-division multiple-access (TDMA) scheme for transmission 
of a signal. In general, maximum average power levels must be used to 
determine compliance.

Subpart K_Importation of Devices Capable of Causing Harmful Interference



Sec. 2.1201  Purpose.

    (a) In order to carry out its responsibilities under the 
Communications Act and the various treaties and international 
regulations, and in order to promote efficient use of the radio 
spectrum, the Commission has developed technical standards for radio 
frequency

[[Page 674]]

equipment. The technical standards applicable to individual types of 
equipment are found in that part of the rules governing the service 
wherein the equipment is to be operated. In addition to the technical 
standards, the rules governing the service may require that such 
equipment receive an equipment authorization from the Commission as a 
prerequisite for marketing and importing this equipment into the U.S.A. 
The marketing rules, Sec. 2.801 et seq., were adopted pursuant to the 
authority in section 302 of the Communications Act of 1934, as amended 
(47 U.S.C. 302).
    (b) The rules in this section set out the conditions under which 
radio frequency devices as defined in Sec. 2.801 that are capable of 
causing harmful interference to radio communications may be imported 
into the U.S.A.
    (c) Nothing in this section prevents importers from shipping goods 
into foreign trade zones or Customs bonded warehouses, such as is the 
prescribed procedure under Sec. 2.1204(a)(5). Radio frequency devices 
capable of causing harmful interference, however, cannot be withdrawn 
from these areas except in accordance with the provisions of this 
section.

    (b) Unintentional radiators which are exempted from technical 
standards and other requirements as specified in Sec. 15.103 of this 
chapter.
    (c) Radio frequency devices manufactured and assembled in the U.S.A. 
that meet applicable FCC technical standards and which have not been 
modified or received further assembly.
    (d) Radio frequency devices previously properly imported that have 
been exported for repair and re-imported for use.
    (e) Subassemblies, parts, or components of radio frequency devices 
unless they constitute an essentially completed device which requires 
only the addition of cabinets, knobs, speakers, or similar minor 
attachments before marketing or use. Form 740 information will be 
required to be submitted for computer circuit boards that are actually 
peripheral devices as defined in Sec. 15.3(r) of this chapter and all 
devices that, by themselves, are subject to FCC marketing rules.

[56 FR 26619, June 10, 1991]



Sec. 2.1203  General requirement for entry into the U.S.A.

    (a) No radio frequency device may be imported into the Customs 
territory of the United States unless the importer or ultimate 
consignee, or their designated customs broker, declares that the device 
meets one of the conditions for entry set out in this section.
    (b) A separate declaration shall be used for each line item in the 
entry or entry summary containing an RF device, or for each different 
radio frequency device within a line item when the elements of the 
declaration are not identical.
    (c) Failure to properly declare the importation category for an

Subpart N_FCC Procedure for Testing Class A, B and S Emergency Position 
                    Indicating Radiobeacons (EPIRBs)

    Source: 56 FR 11683, Mar. 20, 1991, unless otherwise noted.

                                 General



Sec. 2.1501  Introduction.

    The procedure described herein sets forth uniform methods for 
testing Class A, B and S Emergency Position Indicating Radiobeacons 
(EPIRBs) for compliance with the applicable portions of the FCC Rules 
and Regulations. Other methods and test results may be used provided 
they are fully documented and deemed by the Commission to yield results 
equivalent to the procedures set forth in this section.



Sec. 2.1503  Test environment.

    (a) Measurement sites. Radiated emission tests for peak effective 
radiated power (PERP), spurious emissions and power in the test mode are 
to be performed on an open field test site as shown in Figure 1. The 
site is to be located on level ground with an obstruction-free, 60 m by 
52 m, elliptical area. The site is to be equipped with an antenna mast 
capable of adjustment from 1 to 4 m. The center of a metal ground plane 
at least one wavelength in diameter at 121.5 MHz (2.47 m) is to be 
located 30 m from the receiving antenna. The ground plane is to have 
provisions for mounting removable quarter-wave verticle elements to 
produce a

[[Page 678]]

monopole antenna at both 121.5 and 243 MHz with the VSWR of less than 
1.5.

    Note: It is desirable that the level of radiated ambient EME at the 
test site be at least 6 dB below the FCC limits applicable to the EPIRB. 
It is, of course, not always possible to meet this condition. If the 
ambient field strength at some frequencies within the specified 
measurement ranges is too high, it is recommended that one or more of 
the following corrective steps be employed:
    (1) Perform measurements in critical frequency bands during hours 
when broadcast and other radio stations are off-the-air and ambients 
from industrial equipment are lower.
    (2) Insofar as is possible, orient the axis of an open area test 
site to discriminate against strong ambient signals.
    (3) Vary the bandwidth of the measuring instrument to separate 
ambient EME from emissions from the EPIRB.

    (b) Temperature. Except as otherwise noted, the ambient temperature 
during testing is to be within the range of 4 to 35 [deg]C (40 to 95 
[deg]F).



Sec. 2.1505  Test instrumentation and equipment.

    (a) Receiver (field intensity meter). A calibrated field intensity 
meter (FIM) with a frequency range of 30 to 1000 MHz is required for 
measuring radiated emission levels. This instrument should be capable of 
making peak measurements with a bandwidth of 100 kHz.
    (b) Spectrum analyzer. Spectral measurements are to be made with a 
spectrum analyzer with a minimum resolution bandwidth no greater than 10 
Hz. The video filter, if used, should have a bandwidth wide enough so as 
to not affect peak readings. A linear video output is desirable for 
performing measurements of modulation characteristics.
    (c) Storage oscilloscope. Measurements of modulation characteristics 
are to be made using a calibrated storage oscilloscope. This instrument 
is to be DC coupled and capable of manually triggered single sweeps.
    (d) Frequency counter. A frequency counter with an accuracy of at 
least 5 parts per million is required for measuring the carrier 
frequency.
    (e) Signal generator. A calibrated signal generator with an output 
of at least 75 mW at 121.5 and 243 MHz is required for generating a 
reference signal for site calibration.
    (f) Antenna. Radiated emissions are to be measured with calibrated, 
tuned, half-wave dipole antennas covering the frequency range of 30 to 
1000 MHz.
    (g) Temperature chamber. Tests which call for subjecting the EPIRB 
to temperature levels other than the ambient temperature are to be 
performed in a temperature test chamber which can be adjusted to stable 
temperatures from -20 to +55 [deg]C. This chamber is to be of sufficient 
size to accommodate the EPIRB under test.
    (h) Vibration table. A vibration table capable of vibrating the 
EPIRB with a sinusoidal motion is required. The table must be capable of 
varying the frequency of vibration either linearly or logarithmically 
over a range of 4 to 33 Hz with maximum peak amplitudes of up to 2.5 mm.
    (i) Salt fog chamber. A chamber capable of producing salt fog at a 
temperature of 35 [deg]C for 48 hours is required. This chamber is to be 
of sufficient size to accommodate the EPIRB under test.
    (j) Drop test facility. A facility which will permit dropping an 
EPIRB from a height of 20 m into water is required. The water must be 
deep enough so that the EPIRB will not touch bottom when dropped.

              Environmental and Operational Test Procedures



Sec. 2.1507  Test frequencies.

    Testing of an EPIRB for compliance outside a shielded room on a 
distress frequency is prohibited, since this may interfere with 
emergency communications. Therefore, all compliance testing outside a 
shielded room should be conducted on one of the pairs of alternate 
frequencies specified below:

121.600/243.200 MHz
121.650/243.300 MHz
121.700/243.400 MHz
121.750/243.500 MHz
121.800/243.600 MHz
121.850/243.700 MHz
121.900/243.800 MHz


The above frequencies are to be used for limited testing of EPIRBs for 
compliance with FCC Rules, subject to the following conditions:

[[Page 679]]

    (a) The testing shall not cause harmful interference to authorized 
communications on these frequencies.
    (b) The testing shall be coordinated with the nearest FCC district 
office.

For simplicity, 121.5 MHz and 243 MHz will be used throughout this test 
procedure to indicate the alternate test frequency.



Sec. 2.1509  Environmental and duration tests.

    The environmental and operational tests in Sec. 2.1509 (a) through 
(e) are to be conducted on a single test unit in the order given below. 
This sequence of tests also includes the electrical tests in Sec. Sec. 
2.1511, 2.1513 and 2.1515 of this part. The test unit is not to be 
adjusted, nor is the battery to be replaced during these tests, and a 
log of battery on-time should be maintained. The above tests are to be 
performed on the same test unit. The tests in Sec. 2.1509 (f) through 
(i) may be run in any sequence or may be performed on separate test 
units.
    (a) Vibration test.

    Step (1) Secure the EPIRB to the vibration table. The EPIRB is not 
to be operated and should not activate while being vibrated.
    Step (2) Subject the EPIRB to sinusoidal motion parallel to one of 
the three major orthogonal axes under the following conditions:

 
         A. Frequency (Hz)                   Peak amplitude (mm)
 
                      4-10                                    2.5
                     10-15                                    0.8
                     15-25                                    0.4
                     25-33                                    0.2
 

    B. The frequency is to be changed either linearly or logarithmically 
with time between 4 Hz and 33 Hz such that a complete cycle (4 Hz to 33 
Hz to 4 Hz) takes approximately 5 minutes.
    C. The EPIRB is to be vibrated for at least 30 minutes or six 
complete cycles.
    Step (3) Remount the EPIRB, if necessary, and repeat step 2 for each 
of the other two major orthogonal axes.
    Step (4) Upon completion of the test, perform an exterior mechanical 
inspection and verify operation by turning the unit on and observing the 
RF power indicator on the unit or monitoring the transmission with a 
receiver. Record test results.

    (b) Thermal shock tests. These tests are to be performed on EPIRBs 
which are required or intended to float.
    (1) Low temperature thermal shock test.

    Step (1) Place the EPIRB in a temperature chamber for at least 3 
hours at -20 [deg]C or colder. The EPIRB is not to be operated while 
being cooled.
    Step (2) Immediately place the EPIRB in water that has been 
maintained at +10 [deg]C or warmer.
    Step (3) After 15 minutes, perform as exterior mechanical inspection 
and verify operation by turning the unit on and observing the RF power 
indicator on the unit or monitoring the transmission with a receiver. 
Record test results.

    (2) High temperature thermal shock test.

    Step (1) Place the EPIRB in a temperature chamber for at least 3 
hours at +55 degrees C or warmer. The EPIRB is not to be operated while 
being heated.
    Step (2) Immediately float the EPIRB in water that is maintained at 
+25 degrees C or colder.
    Step (3) After 15 minutes, perform an exterior mechanical inspection 
and verify operation by turning the unit on and observing the RF power 
indicator on the unit or monitoring the transmission with a receiver. 
Record test results.

    (c) Salt fog test.

    Step (1) Place the EPIRB in a salt fog chamber for a period of at 
least 2 hours at a temperature of 35 [deg]C (2 
[deg]C) before exposing it to salt fog. The EPIRB is to be turned off 
during this test.
    Step (2) With the chamber temperature maintained at 35 [deg]C, 
introduce salt fog at the saturation point for 48 hours. The salt fog is 
to be prepared from a 5% (1%) salt (sodium 
chloride solution. For detailed guidance on the preparation of the 
solution and the apparatus for generating salt fog, refer to MIL-STD-
810D (19 July 1983), method 509.2.
    Step (3) Upon completion of the salt fog exposure, the EPIRB is to 
be airdried at room temperature for 12 hours and operation verified by 
turning the unit on and observing the RF power indicator on the unit or 
monitoring the transmission with a receiver. Record observations.

    (d) Drop test. This test is to be performed on EPIRB which are 
required or intended to float.

    Step (1) Turn the EPIRB on, log the time and drop it three times 
into water from a height of 20 meters. The water is to be deep enough so 
that the EPIRB does not touch bottom when dropped. Each drop should be 
initiated from a different orientation as follows: antenna vertical up; 
antenna vertical down; antenna horizontal.
    Step (2) Upon completion of the drop test, an exterior mechanical 
inspection is to be

[[Page 680]]

performed and operation verified by observing the RF power indicator on 
the unit or monitoring the transmission with a receiver. Record 
observations. Turn the test unit off and log the total on-time.

    (e) Forty-eight hour operational test. This test includes the 
battery life test and all the electrical tests given in Sec. Sec. 
2.1511, 2.1513 and 2.1515 of this part, at various temperatures. The 
tests are to be performed on the same EPIRB in the sequence specified 
herein. Be sure to record the on-time of the unit during each test. No 
more than 8 hours of total on-time is permitted before commencing step 
4. When operating the EPIRB in the environmental chamber, a non-
radiating load may be substituted for the antenna provided it is 
electrically equivalent to the standard antenna and does not reduce the 
battery current drain.

    Step (1) Perform the radiated emissions test in Sec. 2.1511 of this 
part.
    Step (2) Perform the modulation characteristic tests in Sec. 2.1513 
of this part.
    Step (3) Perform the spectral tests in Sec. 2.1515 of this part.
    Step (4) With the EPIRB off, place unit in an environmental chamber 
at a temperature of -20 [deg]C for at least 2 hours.
    Step (5) With the EPIRB in the chamber, repeat the carrier frequency 
test in Sec. 2.1515(d) of this part. (Leave the EPIRB turned on.)
    Step (6) Near the end of 48 hours of total on-time for the EPIRB, 
repeat the carrier frequency test in Sec. 2.1515(d) of this part.
    Step (7) At the end of 48 hours of total on-time, remove EPIRB from 
the chamber and immediately repeat the PERP test for the fundamental 
emissions in Sec. 2.1511(c) of this part. The unit should be maintained 
at -20 [deg]C to the extent possible for this test.

    (f) Float free and activation test. This test is required only for 
Class A EPIRBs.

    Step (1) The EPIRB is to be installed in the automatic release 
mechanism and the assembly is to be mounted on a fixture simulating a 
deck or bulkhead as per manufacturer' installation instructions.
    Step (2) Submerge the fixture in water in its normal mounted 
orientation. The EPIRB must float free before reaching a depth of 4 
meters and should automatically activate. Activation is to be verified 
by observing the RF power indicator on the unit or monitoring the 
transmission with a receiver.
If the EPIRB is equipped with an automatically deployable antenna, the 
antenna must properly deploy during each immersion. Record observations.

    (g) Stability and buoyancy test. This test is to be performed on 
EPIRBs which are required or intended to float. This test is to be 
conducted in fresh water.

    Step (1) With the antenna deployed in its normal operating position, 
submerge the EPIRB in a horizontal position just below the surface of 
the water.
    Step (2) Release the EPIRB and observe the amount of time required 
for it to come to an upright position. It must reach its upright 
position within one second from each position.
The EPIRB must have a reserve buoyancy of at least 5% of its gross 
weight. It must also float upright in calm water with the base of the 
antenna a minimum of 5 cm above the water. Record the time required for 
the test unit to right itself.

    (h) Temperature/frequency test. The frequency stability shall be 
measured over an ambient temperature from -20[deg] to +55 [deg]C at 
intervals of not more than 10 [deg]C. A period of time sufficient to 
stabilize all of the components of the oscillator circuit at each 
temperture level shall be allowed prior to frequency measurement.

    Step (1) Place the EPIRB in the environmental test chamber.
    Step (2) Adjust the temperature in the chamber to +20 [deg]C and 
allow sufficient time for the oscillator to stabilize at that 
temperature.
    Step (3) Measure the carrier frequency in accordance with the 
procedure in Sec. 2.1515(d) of this part. Record the carrier frequency 
in Hertz. The carrier frequency at +20 [deg]C is the reference for 
determining the frequency tolerance.
    Step (4) Increase the temperature in the chamber to +55 [deg]C and 
allow sufficient time for the oscillator to stabilize at that 
temperature. Measure the carrier frequency using the procedure in Sec. 
2.1515(d) of this part.
    Step (5) Reduce the temperature in the chamber in 10 [deg]C maximum 
increments until -20 [deg]C is reached. At each new temperature, allow 
sufficient time for the oscillator to stabilize at that temperature. 
Measure the temperature and frequency in each case and plot the 
frequency vs temperature from -20[deg] to +55 [deg]C.

    (i) Leakage and immersion test.

    Step (1) Completely submerge the EPIRB in water for 48 hours. The 
EPIRB is to be turned off during this test.
    Step (2) Remove the EPIRB from the water and wipe dry.
    Step (3) Verify operation by briefly turning the EPIRB on and 
observing the RF power

[[Page 681]]

indicator on the unit or monitoring the transmission with a receiver.
    Step (4) Open the EPIRB for examination. There is to be no water 
inside the unit. Record observations.



Sec. 2.1511  Measurements of radiated emissions.

    The Commission's Rules require that the peak efficetive radiated 
power (PERP) of a Class A, B or S EPIRB not be less than 75 mW under 
certain specified conditions. The PERP of an EPIRB transmitter is 
determined by comparing its level to a reference PERP generated by a 
standard quarter-wave monopole antenna located on a one wavelength 
minimum diameter metal ground plane. The Rules also require that all 
spurious and harmonic emissions be attenuated by a specified amount with 
respect to the reference PERP. In addition, there is a limit on the PERP 
of radiated emissions with the switch in the test mode. These 
measurements are to be made in accordance with the following procedure.
    (a) General set-up instructions. Measurements of radiated 
electromagnetic emissions (EME) are to be performed on the 30 meter open 
field test site described in Sec. 2.1503(a) of this part and on one of 
the pair of frequencies listed in Sec. 2.1507 of this part. A receiver, 
tuned dipole antennas and a calibrated signal generator as described in 
Sec. 2.1505 of this part are required. The EPIRB should be powered by 
its own internal battery with its standard antenna attached and 
deployed.
    (b) Set-up for radiated EME tests.

    Step (1) Place a 121.5 MHz quarter-wave vertical antenna element at 
the center of the ground plane and connect the output of the calibrated 
signal generator to the antenna.
    Step (2) Mount the tuned dipole antenna on the antenna mast, tune 
the elements to 121.5 MHz and connect the antenna to the receiver.
    Step (3) After an appropriate warm up, turn the receiver to the 
frequency of the test unit, set the detector to peak mode and the 
bandwidth to 100 kHz.

    (Note: It is sometimes helpful to monitor the receiver audio output 
with a speaker. The EPIRB signal may be identified by its distinctive 
modulation.)

    (c) Radiated EME tests.

           Fundamental emissions-peak effective radiated power

    Step (1) Turn on the signal generator and adjust the output to 75 mW 
at 121.5 MHz.
    Step (2) Vary the antenna height from one to four meters in both 
vertical and horizontal polarization. Record the highest receiver 
reading in dBm as the reference level.
    Step (3) Disconnect the signal generator and replace the quarter-
wave vertical element on the ground plane with the EPIRB under test. The 
EPIRB is to be positioned directly on the surface of and in the center 
of the metal ground plane.
    Step (4) Activate the EPIRB.
    Step (5) Vary the receive antenna height from one to four meters in 
both vertical and horizontal polarization. Record the highest receiver 
reading in dBm and the instrument settings, antenna height and direction 
for maximum radiation, antenna polarization and conversion factors, if 
any, associated with that reading.
    Step (6) Repeat Step 5 with the EPIRB switch in the test position. 
Return the switch to the normal operation position.
    Step (7) Rotate the EPIRB 30 degrees and repeat Steps 5 and 6. 
Repeat this step for all successive 30 degrees segments of a full, 360 
degree rotation of the EPIRB.
    Step (8) Repeat Sec. 2.1511(b) and Steps 1 through 7 for 243 MHz.
    Step (9) Compute the peak effective radiated power for the maximum 
level of each measured emission using the following formula:
[GRAPHIC] [TIFF OMITTED] TC03JN91.001

where:

dBmmeas is the measured receiver reading in dBm, and
dBmref is the reference receiver reading found in step 2 of 
Sec. 2.1511(c).
    Step (10) Record the PERP in mW. The FCC limit for minimum power in 
the normal operation mode (i.e., with the EPIRB switch in the normal 
operating position) is 75 mW. The FCC limit for maximum power in the 
test mode is 0.0001 mW.

                           Spurious emissions

    Step (11) Reset the signal generator to operate at 121.5 MHz.
    Step (12) For each spurious and harmonic emission to be measured, 
retune the receive antenna to the appropriate frequency and repeat Steps 
5 and 7.
    Step (13) Determine the FCC limit on power for spurious emissions on 
the frequency of each measured emission as follows:
    The rules require that spurious emissions be attenuated at least 30 
decibels below the

[[Page 682]]

transmit power level. Therefore, the maximum received power limit for a 
spurious emission can be calculated from the formula:

dBmspur = dBmmeas+AF121.5-
AFspurfreq-30

where:

dBmmeas = measured receiver reading (Section 2.1511(c), step 
5).
AF121.5 = tuned dipole antenna factor at 121.5 MHz.
AFspurfreq = tuned dipole antenna factor at spurious freq.
    Step (14) Record in dB below the fundamental emissions the level of 
all spurious and harmonic emissions within 10 dB of the FCC limits.



Sec. 2.1513  Measurements of modulation characteristics.

    (a) Set-up. Test of modulation characteristics are to be performed 
in an RF shielded room.

    Step (1) Place the EPIRB directly on a metal ground plane, such as 
the shielded room floor.
    Step (2) Place a suitable receiving antenna at a convenient distance 
from the EPIRB and connect it to the input of the spectrum analyzer or 
receiver to observe the radiated signal from the EPIRB.
    Step (3) Set the spectrum analyzer or receiver controls as follows:
I.F. bandwidth: 300 kHz minimum
Video filter: OFF or as wide as possible
Amplitude scale: Linear
Frequency: 121.5 MHz
Scan width: 0 Hz
    Step (4) Connect the detected output of the spectrum analyzer or 
receiver to the input of the storage oscilloscope.
    Step (5) Set the oscilloscope controls as necessary to allow the 
demodulated waveform to be viewed. The input signal is to be DC coupled.

    (b) Measurement of Audio Frequencies.

    Step (1) Activate the EPIRB.
    Step (2) Trigger the oscilloscope and store at least one complete 
cycle of the audio waveform.
    Step (3) Measure the period (T) of the waveform. The period is the 
time difference between the half voltage points at the beginning and end 
of one complete cycle of the waveform. See Figure 2.
    Step (4) Calculate the frequency (F), where:

F=1/T.

    Step (5) Repeat Steps 2 through 4 until the highest and lowest audio 
frequencies are found.

    Note: The lowest and highest frequencies may occur several cycles 
before or after the transition from low to high frequency.)

    Step (6) Determine the audio frequency range (Frange), 
where:

Frange=Fhigh-Flow

    Step (7) Record instrument settings and the lowest and highest audio 
frequencies. Record the audio frequency range in Hertz.
    Step (8) Repeat Steps 1-7, above, for 243 MHz.

    (c) Modulation factor.

    Step (1) Activate the EPIRB.
    Step (2) Trigger the oscilloscope and store at least one complete 
cycle of the audio waveform. The input signal is to be DC coupled or 
erroneous results will be obtained.
    Step (3) Measure the maximum voltage (Vmax), and the 
minimum voltage (Vmin) for the cycle. The modulation factor 
(M) is calculated from the following formula:
[GRAPHIC] [TIFF OMITTED] TC03JN91.002

    See Figure 2.
    Step (4) Repeat Steps 2 and 3 until the lowest modulation factor is 
found.
    Step (5) Record instrument settings and the lowest modulation 
factor, expressed as a ratio between 0 and 1.
    Step (6) Repeat the above measurements for 243 MHz.

    (d) Modulation duty cycle.

    Step (1) Activate the EPIRB.
    Step (2) Trigger the oscilloscope and store at least one complete 
cycle of the audio waveform.
    Step (3) Measure the period (T) of the waveform. The period is the 
time difference between the half voltage points at the beginning and end 
of one cycle of the waveform. See Figure 2.
    Step (4) Measure the pulse width (tp) of the waveform. 
The pulse width is the time difference between the half voltage points 
on the rising and falling portions of the waveform. See Figure 2.
    Step (5) Calculate the duty cycle (D) as follows:
    [GRAPHIC] [TIFF OMITTED] TC03JN91.003
    
    Step (6) Repeat Steps 2 through 5 a sufficient number of times to 
determine the highest and lowest duty cycles.
    Step (7) Record instrument settings and the highest and lowest duty 
cycles in percent.
    Step (8) Repeat Steps 1-7 for 243 MHz.

    (e) Sweep repetition rate.

    Step (1) Connect a speaker to the detected output of the spectrum 
analyzer or receiver

[[Page 683]]

so the audio frequencies are audible. Alternatively, an FM radio tuned 
to 108 MHz placed in the vicinity of the EPIRB may be used.
    Step (2) Activate the EPIRB.
    Step (3) Time the number of audio sweeps (N) for a one minute 
interval.
    Step (4) Calculate the audio sweep rate (R) using R=N/60.
    Step (5) Record instrument settings and the sweep repetition rate in 
Hertz.



Sec. 2.1515  Spectral measurements.

    (a) Set-up. Spectral measurements are to be performed in a shielded 
room.

    Step (1) Place the EPIRB directly on a metal ground plane, such as 
the shielded room floor. The EPIRB should be powered by its own internal 
battery with its standard antenna attached and deployed.
    Step (2) Place a suitable receiving antenna at a convenient distance 
from the EPIRB and connect it to the input of the spectrum analyzer to 
observe the radiated signal from the EPIRB. A signal generator and 
frequency counter capable of operating at 121.5 and 243 MHz are also 
required for these tests.

    (b) Occupied bandwidth test.

    Step (1) Activate the EPIRB and observe the fundamental frequency on 
a spectrum analyzer. Adjust location of receiving antenna and spectrum 
analyzer controls to obtain a suitable signal level (i.e., a level which 
will not overload the spectrum analyzer, but is far enough above the 
noise floor to allow determination of whether or not the sidebands are 
attenuated by at least the amount required in the rules).
    Step (2) Set spectrum analyzer controls as follows:

I.F. bandwidth: 10 kHz
Video filter: OFF or as wide as possible
Scan time: 100 ms./div.
Amplitude scale: 10 dB/div.
Scan width: 20 Hz/div.
Center frequency: 121.5 MHz

    Step (3) Record the signal level in dbm.
    Step (4) Calculate the mean power reference level by adding 10 
log10 (D), where D is the modulation duty cycle determined in 
section 2.1513(d) of this part, to the recorded signal level.
    Step (5) Set spectrum analyzer controls as follows:

I.F. bandwidth: 100 Hz
Video filter: OFF or as wide as possible
Scan time: 10 sec./div.
Amplitude scale: 10 dB/div.
Scan width: 20 kHz/div.

    Step (6) Check the modulation sidebands for compliance with the 
required attenuation below the mean power reference level specified in 
Sec. 80.211 of the rules.
    Step (7) Record how the test was performed, instrument settings and 
the occupied bandwidth in kHz and the 3 dB bandwidth of the carrier in 
Hz. (See Sec. 2.1517 of this part).
    Step (8) Repeat Steps 1 through 7 for the signal at 243 MHz.

    (c) Signal enhancement test. The setup specified in Sec. 2.1515(a) 
is to be used in this method of measuring signal enhancement. Other 
methods may be used if shown to give results equivalent to or more 
accurate than this method.

    Step (1) Activate the EPIRB and locate the carrier frequency at 
121.5 MHz on the spectrum analyzer. Adjust location of receiving antenna 
and spectrum analyzer controls to obtain a suitable signal level (i.e., 
a level which will not overload the analyzer, but is far enough above 
the noise floor to allow sidebands at least 40 dB below the carrier to 
be viewed).
    Step (2) Set the spectrum analyzer controls as follows:

I.F. bandwidth: 10 kHz
Video filter: OFF or as wide as possible
Scan time: 100 ms./div.
Amplitude scale: 5 dB/div.
Scan width: 10 kHz/div.
Center frequency: 121.5 MHz

    Step (3) Record the amplitude in dBm.
    Step (4) Calculate the total power output by adding 10 log(D), where 
D is the modulation duty cycle determined in Sec. 2.1513(d) of this 
part, to the recorded signal level.
    Step (5) Set the spectrum analyzer controls as follows:

I.F. bandwidth: 60 Hz or less
Video filter: OFF or as wide as possible
Scan time: 10 sec./div.
Amplitude scale: 5 dB/div.
Scan width: 20 Hz/div.
Center frequency: 121.5 MHz

    Step (6) Measure and record the carrier power dBm as displayed on 
the spectrum analyzer.
    Step (7) Calculate the ratio of carrier power to total power from 
Steps 4 and 6 using the following formula:

dBC = carrier power in step 6
dBT = total power in step 4

    Step (8) Record instrument settings, sample calculation and the 
percent of power within 30 Hz at 121.5 MHz or 
60 Hz at 243 MHz of the carrier frequency.
    Step (9) Repeat the above measurement Steps 1 through 8 for 243 MHz. 
For the higher frequency, the I.F. bandwidth in step 5 must be 120 Hz or 
less.

    (d) Carrier frequency test. The setup specified in Sec. 2.1515(a) 
is to be used in measuring the carrier frequency.

    Step (1) Activate the EPIRB and locate the 121.5 MHz signal on the 
spectrum analyzer. Adjust location of receiving antenna and spectrum 
analyzer controls to obtain a suitable signal level.
    Step (2) Set the spectrum analyzer controls as follows:

I.F. bandwidth: 100 Hz
Video filter: OFF or as wide as possible
Scan time: 10 sec./div.
Amplitude scale: 10 dB/div.
Scan width: 20 Hz/div.
Center frequency: 121.5 MHz

    Step (3) Combine the output of the signal generator with the EPIRB 
signal at the input to the spectrum analyzer.
    Step (4) Adjust amplitude and frequency of signal generator output 
to determine center of carrier frequency component.
    Step (5) Measure signal generator frequency with frequency counter 
with accuracy of 5 PPM or better and record as carrier frequency.
    Step (6) If applicable, change the type of modulation of the EPIRB 
and record the shift in carrier frequency as observed on the spectrum 
analyzer display.
    Step (7) Repeat the above measurement Steps 1 through 6 for 243 MHz.
