modulated with the coded information in a conventional manner 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 of change in the hop set.

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 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 of the

§ 2.102 Assignment of frequencies.
top
(a) Except as otherwise provided in this section, the assignment of
frequencies and bands of frequencies to all stations and classes of stations
and the licensing and authorizing of the use of all such frequencies between
9 kHz and 275 GHz, and the actual use of such frequencies for
radiocommunication or for any other purpose, including the transfer of
energy by radio, shall be in accordance with the Table of Frequency
Allocations in §2.106.
(b) On the condition that harmful interference will not be caused to
services operating in accordance with the Table of Frequency Allocations the
following exceptions to paragraph (a) of this section may be authorized:
(1) In individual cases the Commission may, without rule making proceedings,
authorize on a temporary basis only, the use of frequencies not in
accordance with the Table of Frequency Allocations for projects of short
duration or emergencies where the Commission finds that important or
exceptional circumstances require such utilization. Such authorizations are
not intended to develop a service to be operated on frequencies other than
those allocated such service.
(2) A station for the development of techniques or equipment to be employed
by services set forth in column 5 of the Table of Frequency Allocations may
be authorized the use of frequencies allocated to those services or classes
of stations.
(3) Experimental stations, pursuant to part 5 of this chapter, may be
authorized the use of any frequency or frequency band not exclusively
allocated to the passive services (including the radio astronomy service).
(4) In the event a band is reallocated so as to delete its availability for
use by a particular service, the Commission may provide for the further
interim use of the band by stations in that service for a temporary,
specific period of time.
(c) Non-Federal stations may be authorized to use Federal frequencies in the
bands above 25 MHz if the Commission finds, after consultations with the
appropriate Federal agency or agencies, that such use is necessary for
coordination of Federal and non-Federal activities: Provided, however, that:
(1) Non-Federal operation on Federal frequencies shall conform with the
conditions agreed upon by the Commission and NTIA (the more important of
which are contained in paragraphs (c)(2), (c)(3), and (c)(4) of this
section);
(2) Such operations shall be in accordance with NTIA rules governing the
service to which the frequencies involved are allocated;
(3) Such operations shall not cause harmful interference to Federal stations
and, should harmful interference result, that the interfering non-Federal
operation shall immediately terminate; and
(4) Non-Federal operation has been certified as necessary by the Federal
agency involved and this certification has been furnished, in writing, to
the non-Federal 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-Federal 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-Federal 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-Federal 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;
(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.

§ 2.103 Federal use of non-Federal frequencies.
top
Link to an amendment published at 72 FR 48843 , Aug. 24, 2007.
(a) Federal stations may be authorized to use non-Federal 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 Federal and non-Federal activities: Provided, however, that:
(1) Federal operation on non-Federal frequencies shall conform with the
conditions agreed upon by the Commission and NTIA (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-Federal
stations and, should harmful interference result, that the interfering
Federal operation shall immediately terminate; and
(4) Federal operation has been certified as necessary by the non-Federal
licensees involved and this certification has been furnished, in writing, to
the Federal agency with which communication is required.
(b) Federal stations may be authorized to use channels in the 764–776 MHz,
794–806 MHz and 4940–4990 MHz public safety bands with non-Federal entities
if the Commission finds such use necessary; where:
(1) The stations are used for interoperability or part of a
Federal/non-Federal shared or joint-use system;
(2) The Federal entity obtains the approval of the non-Federal (State/local
government) licensee(s) or applicant(s) involved;
(3) Federal operation is in accordance with the Commission's Rules governing
operation of this band and conforms with any conditions agreed upon by the
Commission and NTIA; and
(4) Interoperability, shared or joint-use systems are the subject of a
mutual agreement between the Federal and non-Federal 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.
[ 63 FR 58650 , Nov. 2, 1998, as amended at 68 FR 38638 , June 30, 2003; 70 FR 46586 , Aug. 10, 2005]
§ 2.104 International Table of Frequency Allocations.
top
(a) The International Table of Frequency Allocations is subdivided into the
Region 1 Table (column 1 of §2.106), the Region 2 Table (column 2 of
§2.106), and the Region 3 Table (column 3 of §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, the Russian Federation, Georgia, Kazakhstan, Mongolia,
Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and the
area to the north of the 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,
the Russian Federation, Georgia, Kazakhstan, Mongolia, Uzbekistan,
Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and the area to the
north of the 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° East of
Greenwich to parallel 40° North; thence by great circle arc to the
intersection of meridian 60° East and the Tropic of Cancer; thence along the
meridian 60° East to the South Pole.
(ii) Line B. Line B extends from the North Pole along meridian 10° West of
Greenwich to its intersection with parallel 72° North; thence by great
circle arc to the intersection of meridian 50° West and parallel 40° North;
thence by great circle arc to the intersection of meridian 20° West and
parallel 10° South; thence along meridian 20° 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°30' North with the international boundary in
Bering Strait; thence by great circle arc to the intersection of meridian
165° East of Greenwich and parallel 50° North; thence by great circle arc to
the intersection of meridian 170° West and parallel 10° North; thence along
parallel 10° North to its intersection with meridian 120° West; thence along
meridian 120° 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° South and 30° North;
(ii) Islands in the Indian Ocean west of meridian 60° East of Greenwich,
situated between the parallel 40° South and the great circle arc joining the
points 45° East, 11°30' North and 60° East, 15° North; and
(iii) Islands in the Atlantic Ocean east of line B, situated between the
parallels 40° South and 30° North.
(2) The “European Broadcasting Area” is bounded on the west by the western
boundary of Region 1, on the east by the meridian 40° East of Greenwich and
on the south by the parallel 30° 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 the Syrian Arab Republic, 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° North from its intersection with meridian 55° East of
Greenwich to its intersection with meridian 5° West, then along meridian 5°
West to its intersection with parallel 67° North, thence along parallel 67°
North to its intersection with meridian 32° West; to the west by a line
extending along meridian 32° West to its intersection with parallel 30°
North; to the south by a line extending along parallel 30° North to its
intersection with meridian 43° East; to the east by a line extending along
meridian 43° East to its intersection with parallel 60° North, thence along
parallel 60° North to its intersection with meridian 55° East and thence
along meridian 55° East to its intersection with parallel 72° 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° North and 35° South with the addition of:
(A) The area contained between the meridians 40° East and 80° East of
Greenwich and the parallels 30° North and 40° North; and
(B) That part of Libyan Arab Jamahiriya north of parallel 30° North.
(iii) In Region 2, the Tropical Zone may be extended to parallel 33° North,
subject to special agreements between the countries concerned in that Region
(see Article 6 of the ITU Radio Regulations ).
(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 §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.
(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 in the International
Table that a service or stations in a service may operate in a specific
frequency band subject to not causing harmful interference to another
service or to another station in the same service, this means also that the
service which is subject to not causing harmful interference cannot claim
protection from harmful interference caused by the other service or other
station in the same service.
(2) Where it is indicated in the International Table that a service or
stations in a service may operate in a specific frequency band subject to
not claiming protection from another service or from another station in the
same service, this means also that the service which is subject to not
claiming protection shall not cause harmful interference to the other
service or other station in the same service.
(3) 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 more than one of the allocated
services, or 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.

§ 2.105 United States Table of Frequency Allocations.
top
(a) The United States Table of Frequency Allocations (United States Table)
is subdivided into the Federal Table of Frequency Allocations (Federal
Table, column 4 of §2.106) and the non-Federal Table of Frequency
Allocations (non-Federal Table, column 5 of §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 Table is administered by NTIA^5 and the non-Federal
Table is administered by the Federal Communications Commission (FCC).^6
^1 See 2.104(b) for definitions of the ITU Regions.
^2 The Caribbean insular areas are Puerto Rico, 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 Region 3 Table ( i.e. , column 3 of 2.106).
The Pacific insular areas located in Region 3 are American Samoa, Guam, the
Northern Mariana Islands, 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 Public
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
or non-Federal 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
FIXED, non-Federal MOBILE]. The terms used to designate categories of
services and allocations^7 in columns 4 and 5 of §2.106 correspond to the
terms in the ITU Radio Regulations.
^7 The radio services are defined in §2.1.
(c) Category of services. (1) Any segment of the radio spectrum may be
allocated to the Federal and/or non-Federal 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 operations and column 5 for non-Federal operations, 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 column 4, then the Federal sector has
no access to that band except as provided for by §2.103. If there is no
service or footnote indicated for a band of frequencies in column 5, then
the non-Federal sector has no access to that band except as provided for by
§2.102.
(2) When the Federal Table and the non-Federal Table 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 Table, given in column 4, is included for informational
purposes only.
(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 “5.” followed by one or more digits, e.g. ,
5.53, denotes an international footnote. Where an international footnote is
applicable, without modification, to both Federal and non-Federal
operations, the Commission places the footnote in both the Federal Table and
the non-Federal Table (columns 4 and 5) and the international footnote is
binding on both Federal users and non-Federal licensees. If, however, an
international footnote pertains to a service allocated only for Federal or
non-Federal use, the international footnote will be placed only in the
affected Table. For example, footnote 5.142 pertains only to the amateur
service, and thus, footnote 5.142 is shown only in the non-Federal Table.
(ii) Any footnote consisting of the letters “US” followed by one or more
digits, e.g. , US7, denotes a stipulation affecting both Federal and
non-Federal operations. United States footnotes appear in both the Federal
Table and the non-Federal Table.
(iii) Any footnote consisting of the letters “NG” followed by one or more
digits, e.g. , NG2, denotes a stipulation applicable only to non-Federal
operations. Non-Federal footnotes appear solely in the non-Federal 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 Federal
operations. Federal footnotes appear solely in the Federal Table (column 4).
(e) Rule Part Cross References. If a frequency or frequency band has been
allocated to a radiocommunication service in the non-Federal Table, then a
cross reference may be added for the pertinent FCC Rule part (column 6 of
§2.106). For example, the band 849–851 MHz is allocated to the aeronautical
mobile service for non-Federal use, 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 §2.106.
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.
(f) The Commission updates §2.106 shortly after a final rule that revises
that section is released. The address for the FCC Radio Spectrum Home Page,
which includes the FCC Online Table of Frequency Allocations and the FCC
Allocation History File, is http://www.fcc.gov/oet/spectrum/.

International Footnotes
5.53 Administrations authorizing the use of frequencies below 9 kHz shall
ensure that no harmful interference is caused thereby to the services to
which the bands above 9 kHz are allocated.
5.54 Administrations conducting scientific research using frequencies below
9 kHz are urged to advise other administrations that may be concerned in
order that such research may be afforded all practicable protection from
harmful interference.
5.55 Additional allocation: in Armenia, Azerbaijan, Bulgaria, Georgia,
Kyrgyzstan, the Russian Federation, Tajikistan and Turkmenistan, the band
14–17 kHz is also allocated to the radionavigation service on a primary
basis.
5.56 The stations of services to which the bands 14–19.95 kHz and 20.05–70
kHz and in Region 1 also the bands 72–84 kHz and 86–90 kHz are allocated may
transmit standard frequency and time signals. Such stations shall be
afforded protection from harmful interference. In Armenia, Azerbaijan,
Belarus, Bulgaria, the Russian Federation, Georgia, Kazakhstan, Mongolia,
Kyrgyzstan, Slovakia, the Czech Rep., Tajikistan and Turkmenistan, the
frequencies 25 kHz and 50 kHz will be used for this purpose under the same
conditions.
5.57 The use of the bands 14–19.95 kHz, 20.05–70 kHz and 70–90 kHz (72–84
kHz and 86–90 kHz in Region 1) by the maritime mobile service is limited to
coast radiotelegraph stations (A1A and F1B only). Exceptionally, the use of
class J2B or J7B emissions is authorized subject to the necessary bandwidth
not exceeding that normally used for class A1A or F1B emissions in the band
concerned.
5.58 Additional allocation: In Armenia, Azerbaijan, the Russian
Federation, Georgia, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan,
the band 67–70 kHz is also allocated to the radionavigation service on a
primary basis.
5.59 Different category of service: in Bangladesh and Pakistan, the
allocation of the bands 70–72 kHz and 84–86 kHz to the fixed and maritime
mobile services is on a primary basis (see No. 5.33).
5.60 In the bands 70–90 kHz (70–86 kHz in Region 1) and 110–130 kHz
(112–130 kHz in Region 1), pulsed radionavigation systems may be used on
condition that they do not cause harmful interference to other services to
which these bands are allocated.
5.61 In Region 2, the establishment and operation of stations in the
maritime radionavigation service in the bands 70–90 kHz and 110–130 kHz
shall be subject to agreement obtained under No. 9.21 with administrations
whose services, operating in accordance with the Table, may be affected.
However, stations of the fixed, maritime mobile and radiolocation services
shall not cause harmful interference to stations in the maritime
radionavigation service established under such agreements.
5.62 Administrations which operate stations in the radionavigation service
in the band 90–110 kHz are urged to coordinate technical and operating
characteristics in such a way as to avoid harmful interference to the
services provided by these stations.
5.64 Only classes A1A or F1B, A2C, A3C, F1C or F3C emissions are authorized
for stations of the fixed service in the bands allocated to this service
between 90 kHz and 160 kHz (148.5 kHz in Region 1) and for stations of the
maritime mobile service in the bands allocated to this service between 110
kHz and 160 kHz (148.5 kHz in Region 1). Exceptionally, class J2B or J7B
emissions are also authorized in the bands between 110 kHz and 160 kHz
(148.5 kHz in Region 1) for stations of the maritime mobile service.
5.65 Different category of service: in Bangladesh, the allocation of the

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.
§ 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.
top
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.

for that emission, as given above, shall be preceded by the necessary
bandwidth of the emission as indicated in §2.202(b)(1).
[ 49 FR 48697 , Dec. 14, 1984]
§ 2.202 Bandwidths.
top
(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:
B[n]= 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
C = Sub-carrier frequency in hertz
D = Peak frequency deviation, i.e., half the difference between the maximum
and minimum values of the instantaneous frequency. The instantaneous
frequency in hertz is the time rate of change in phase in radians divided by
2
t = Pulse duration in seconds at half-amplitude
t[r]= Pulse rise time in seconds between 10% and 90% of maximum amplitude
K = An overall numerical factor which varies according to the emission and
which depends upon the allowable signal distortion.
N[c]= Number of baseband telephone channels in radio systems employing
multichannel multiplexing
P = Continuity pilot sub-carrier frequency (Hz) (continuous signal utilized
to verify performance of frequency-division multiplex systems).
(f) Determination of values of D and B [n]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:
Number of message circuits Multiplying factors Limits of X (P[avg](dBmO))
More than 3, but less than 12 4.47×[a factor specified by the equipment
manufacturer or station licensee, subject to Commission approval]
3.76 antilog (X+2 log[10]N[c])
At least 12, but less than 60 ————————————— X: −2to +2.6.
20
3.76 antilog (X+4 log[10]N[c])
At least 60, but less than 240 ————————————— X: −5.6to −1.0.
20
3.76 antilog (X+10 log[10]N[c])
240 or more ————————————— X: −19.6to −15.0.
20
Where X represents the average power in a message circuit in dBmO; N[c]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 ( B [n]) normally is considered to be
numerically equal to:
(i) 2 M +2 DK, for systems having no continuity pilot subcarrier or having a
continuity pilot subcarrier whose frequency is not the highest modulating
the main carrier;
(ii) 2 P +2 DK, 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 ( B [n]) for such systems is numerically equal to 2 P or 2 M +2 DK
, 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.

shall be performed following the procedures in §2.933.
[ 62 FR 10470 , Mar. 7, 1997, as amended at 63 FR 36598 , July 7, 1998]
§ 2.925 Identification of equipment.
top
(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 §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.
(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 §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.

(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
§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 receive a grantee code electronically via the
Internet at https://gullfoss2.fcc.gov/prod/oet/cf/eas/index.cfm. The code
may be obtained at any time prior to submittal of the application for
equipment authorization. However, the fee required by §1.1103 of this
chapter must be submitted and validated within 30 days of the issuance of
the grantee code, or the code will be removed from the Commission's records
and a new grantee code will have to be obtained.
(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 §§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 §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
§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 §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.

§ 2.1041 Measurement procedure.
top
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 §§2.1046, 2.1047,
2.1049, 2.1051, 2.1053, 2.1055 and 2.1057. See also §2.947.
[ 63 FR 36600 , July 7, 1998]
§ 2.1043 Changes in certificated equipment.
top
(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 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 range,
modulation type or maximum output power (either radiated or conducted)
outside the parameters previously approved, or that change the circumstances
under which the transmitter operates in accordance with Commission rules.
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 the 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. 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 §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 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 §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 §2.1400 in subpart M and
§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 §73.1690 of the FCC's rules.

the tones shall be so adjusted that the two principal frequency components
of the radio frequency signal produced are equal in magnitude.
(e) Transmitters for use in the Radio Broadcast Services:
(1) AM broadcast transmitters for monaural operation—when amplitude
modulated 85% by a 7,500 Hz input signal.
(2) AM broadcast stereophonic operation—when the transmitter operated under
any stereophonic modulation condition not exceeding 100% on negative peaks
and tested under the conditions specified in §73.128 in part 73 of the FCC
rules for AM broadcast stations.
(3) FM broadcast transmitter not used for multiplex operation—when modulated
85 percent by a 15 kHz input signal.
(4) FM broadcast transmitters for multiplex operation under Subsidiary
Communication Authorization (SCA)—when carrier is modulated 70 percent by a
15 kHz main channel input signal, and modulated an additional 15 percent
simultaneously by a 67 kHz subcarrier (unmodulated).
(5) FM broadcast transmitter for stereophonic operation—when modulated by a
15 kHz input signal to the main channel, a 15 kHz input signal to the
stereophonic subchannel, and the pilot subcarrier simultaneously. The input
signals to the main channel and stereophonic subchannel each shall produce
38 percent modulation of the carrier. The pilot subcarrier should produce 9
percent modulation of the carrier.
(6) Television broadcast monaural transmitters—when modulated 85% by a 15

(7) Television broadcast stereophonic sound transmitters—when the
transmitter is modulated with a 15 kHz input signal to the main channel and
the stereophonic subchannel, any pilot subcarrier(s) and any unmodulated
auxiliary subcarrier(s) which may be provided. The signals to the main
channel and the stereophonic subchannel must be representative of the system
being tested and when combined with any pilot subcarrier(s) or other
auxiliary subcarriers shall result in 85% deviation of the maximum specified
aural carrier deviation.
(f) Transmitters for which peak frequency deviation (D) is determined in
accordance with §2.202(f), and in which the modulating baseband comprises
more than 3 independent speech channels—when modulated by a test signal
determined in accordance with the following:
(1) A modulation reference level is established for the characteristic
baseband frequency. (Modulation reference level is defined as the average
power level of a sinusoidal test signal delivered to the modulator input
which provides the specified value of per-channel deviation.)
(2) Modulation reference level being established, the total rms deviation of
the transmitter is measured when a test signal consisting of a band of
random noise extending from below 20 kHz to the highest frequency in the
baseband, is applied to the modulator input through any preemphasis networks
used in normal service. The average power level of the test signal shall
exceed the modulation reference level by the number of decibels determined

§ 2.1053 Measurements required: Field strength of spurious radiation.
top
(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 §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.
(2) All equipment operating on frequencies higher than 25 MHz.
(3) All equipment where the antenna is an integral part of, and attached
directly to the transmitter.
(4) Other types of equipment as required, when deemed necessary by the
Commission.

§ 2.1055 Measurements required: Frequency stability.
top
(a) The frequency stability shall be measured with variation of ambient
temperature as follows:
(1) From −30° to +50° centigrade for all equipment except that specified in
paragraphs (a) (2) and (3) of this section.
(2) From −20° to +50° centigrade for equipment to be licensed for use in the
Maritime Services under part 80 of this chapter, except for Class A, B, and
S Emergency Position Indicating Radiobeacons (EPIRBS), and equipment to be
licensed for use above 952 MHz at operational fixed stations in all
services, stations in the Local Television Transmission Service and
Point-to-Point Microwave Radio Service under part 21 of this chapter,
equipment licensed for use aboard aircraft in the Aviation Services under
part 87 of this chapter, and equipment authorized for use in the Family
Radio Service under part 95 of this chapter.
(3) From 0° to +50° centigrade for equipment to be licensed 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° 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° centigrade and +30° 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° 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.
(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.)

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.

§ 2.1091 Radiofrequency radiation exposure evaluation: mobile devices.
top
(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 §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 §§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 §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 §§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 §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 §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 §1.1310 of this chapter.
However, “source-based” time-averaging 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 §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.

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, §§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
§§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) 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 §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 §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 §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
top
§ 2.1201 Purpose.
top
(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 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, §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 §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 §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.

Subpart N—FCC Procedure for Testing Class A, B and S Emergency Position
Indicating Radiobeacons (EPIRBs)
top
Source: 56 FR 11683 , Mar. 20, 1991, unless otherwise noted.
General
top
§ 2.1501 Introduction.
top
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.
§ 2.1503 Test environment.
top
(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 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 °C (40 to 95 °F).
§ 2.1505 Test instrumentation and equipment.
top
(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 °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 °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
top
§ 2.1507 Test frequencies.
top
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:
(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.
§ 2.1509 Environmental and duration tests.
top
The environmental and operational tests in §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 §§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 §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 °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 °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 °C (±2 °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 °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 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 §§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 §2.1511 of this part.
Step (2) Perform the modulation characteristic tests in §2.1513 of this
part.
Step (3) Perform the spectral tests in §2.1515 of this part.
Step (4) With the EPIRB off, place unit in an environmental chamber at a
temperature of −20 °C for at least 2 hours.
Step (5) With the EPIRB in the chamber, repeat the carrier frequency test in
§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 §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 §2.1511(c) of this part. The unit should be maintained at −20 °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° to +55 °C at intervals of not more
than 10 °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 °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
§2.1515(d) of this part. Record the carrier frequency in Hertz. The carrier
frequency at +20 °C is the reference for determining the frequency
tolerance.
Step (4) Increase the temperature in the chamber to +55 °C and allow
sufficient time for the oscillator to stabilize at that temperature. Measure
the carrier frequency using the procedure in §2.1515(d) of this part.
Step (5) Reduce the temperature in the chamber in 10 °C maximum increments
until −20 °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° to
+55 °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 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.
§ 2.1511 Measurements of radiated emissions.
top
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 §2.1503(a) of this part and on one of the pair of frequencies
listed in §2.1507 of this part. A receiver, tuned dipole antennas and a
calibrated signal generator as described in §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 §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:
[MATH: 
:MATH]
where:
dBm[meas]is the measured receiver reading in dBm, and
dBm[ref]is the reference receiver reading found in step 2 of §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 transmit power level. Therefore, the maximum received power limit
for a spurious emission can be calculated from the formula:
dBm[spur]= dBm[meas]+AF[121.5]−AF[spurfreq]−30
where:
dBm[meas]= measured receiver reading (Section 2.1511(c), step 5).
AF[121.5]= tuned dipole antenna factor at 121.5 MHz.
AF[spurfreq]= 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.
§ 2.1513 Measurements of modulation characteristics.
top
(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 (F[range]), where:
F[range]=F[high]−F[low]
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 (V[max]), and the minimum voltage
(V[min]) for the cycle. The modulation factor (M) is calculated from the
following formula:
[MATH: 
:MATH]
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 (t[p]) 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:
[MATH: 
:MATH]
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 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.
§ 2.1515 Spectral measurements.
top
(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 log[10](D),

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 §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
§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 §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 §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:
[ec03jn91.004.gif]

dB[C]= carrier power in step 6
dB[T]= 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 §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.
