authority to des-ignate another commissioner to serve in hisplace
at any hearing or conference in anyproceeding in which he has been
appointed toserve.
(d) Should a vacancy occur upon any co-operating committee, in a
proceeding involv-ing more than eight States, by reason of thedeath
of any cooperating commissioner, or ofhis ceasing to be a State
commissioner, or ofother inability to serve, it shall be the dutyof
the president of the association to fill thevacancy by appointment,
if, after commu-nication with the chairman of the cooperat-ing
committee, it be deemed necessary to fillsuch vacancy.

cooperating committee involvingnot more than eight States, the
vacancyshall be filled by the commission from whichthe vacancy
occurs.
COOPERATING COMMITTEE TO DETERMINE RE-SPECTING ANY REPORT OF
STATEMENT OF ITSATTITUDE
(a) Whenever a cooperating committeeshall have concluded its
work, or shall deemsuch course advisable, the committee
shallconsider whether it is necessary and desir-able to make a
report to the interested Statecommissions, and, if it shall
determine tomake a report, it shall cause the same to bedistributed
through the secretary of the as-sociation, or through the general
solicitor toall interested commissions.
(b) If a report of the Federal Commissionwill accompany any
order to be made in saidproceeding, the Federal Commission
willstate therein the concurrence or nonconcur-rence of said
cooperating committee in thedecision or order of said Federal
Commis-sion.

required by spreading of the RFenergy about the carrier but rather
toaccommodate the range of frequenciesto which the carrier
frequency can hop.The test of a frequency hopping systemis that the
near term distribution ofhops appears random, the long
termdistribution appears evenly distributedover the hop set, and

flux-density at the same distance. When notspecified otherwise, the
gain refers tothe direction of maximum radiation.The gain may be
considered for a speci-fied polarization.
NOTE: Depending on the choice of the ref-erence antenna a
distinction is made be-tween:
(1) Absolute or isotropic gain (Gi), whenthe reference antenna
is an isotropic an-tenna isolated in space;
(2) Gain relative to a half-wave dipole (Gd),when the reference
antenna is a half-wavedipole isolated in space whose
equatorialplane contains the given direction;

reference antenna is alinear conductor, much shorter than
onequarter of the wavelength, normal to thesurface of a perfectly
conducting planewhich contains the given direction. (RR)

Fre-quency Allocations in § 2.106.
(b) On the condition that harmful in-terference will not be
caused to serv-ices operating in accordance with theTable of
Frequency Allocations the fol-lowing exceptions to paragraph (a)
ofthis section may be authorized:
(1) In individual cases the Commis-sion may, without rule making
pro-ceedings, authorize on a temporarybasis only, the use of
frequencies not inaccordance with the Table of Fre-quency
Allocations for projects ofshort duration or emergencies where
the Commission finds that importantor exceptional circumstances
requiresuch utilization. Such authorizationsare not intended to
develop a service tobe operated on frequencies other thanthose
allocated such service.
(2) A station for the development oftechniques or equipment to
be em-ployed by services set forth in column5 of the Table of
Frequency Allocationsmay be authorized the use of fre-quencies
allocated to those services orclasses of stations.
(3) Experimental stations pursuant topart 5, may be authorized
the use ofany frequency or frequency band notexclusively allocated
to the passiveservices (including the Radio Astron-omy
Service).
(4) In the event a band is reallocatedso as to delete its
availability for useby a particular service, the Commis-sion may
provide for the further in-terim use of the band by stations inthat
service for a temporary, specificperiod of time.
(c) Non-Government stations may beauthorized to use Government
fre-quencies in the bands above 25 MHz ifthe Commission finds,
after consulta-tions with the appropriate Governmentagency or
agencies, that such use isnecessary for coordination of Govern-ment
and non-Government activities:Provided, however, that:
(1) Non-Government operation onGovernment frequencies shall
conformwith the conditions agreed upon by theCommission and the
National Tele-communications and Information Ad-ministration (NTIA)
(the more impor-tant of which are contained in para-graphs (c) (2),
(3), and (4) of this sec-tion);
(2) Such operations shall be in ac-cordance with NTIA rules
governingthe service to which the frequencies in-volved are
allocated;
(3) Such operations shall not causeharmful interference to
Governmentstations and, should harmful inter-ference result, that
the interferingnon-Government operation shall imme-diately
terminate; and

(4) Non-Government operation hasbeen certified as necessary by
the Gov-ernment agency involved and this cer-tification has been
furnished, in writ-ing, to the non-Government licenseewith which
communication is required.
(d) Aircraft stations may commu-nicate with stations of the
maritimemobile service. They shall then con-form to those
provisions of the inter-national Radio Regulations which relateto
the maritime mobile service. Forthis purpose aircraft stations
shoulduse the frequencies allocated to themaritime mobile service.
However,having regard to interference whichmay be caused by
aircraft stations athigh altitudes, maritime mobile fre-quencies in
the bands above 30 MHzshall not be used by aircraft stations inany
specific area without the prioragreement of all administrations of
thearea in which interference is likely tobe caused. In particular,
aircraft sta-tions operating in Region 1 should notuse frequencies
in the bands above 30MHz allocated to the maritime mobileservice by
virtue of any agreement be-tween administrations in that
Region.
(e) Non-Government services operat-ing on frequencies in the
band 25–50MHz must recognize that it is sharedwith various services
of other coun-tries; that harmful interference may becaused by
skywave signals receivedfrom distant stations of all services ofthe
United States and other countriesradiating power on frequencies in
thisband; and that no protection from suchharmful interference
generally can beexpected. Persons desiring to avoidsuch harmful
interference should con-sider operation on available fre-quencies
higher in the radio spectrumnot generally subject to this type
ofdifficulty.
(f) The stations of a service shall usefrequencies so separated
from the lim-its of a band allocated to that serviceas not to cause
harmful interference toallocated services in immediately ad-joining
frequency bands.
(g) In the bands above 25 MHz whichare allocated to the
non-Governmentland mobile service, fixed stations maybe authorized
on the following condi-tions:
(1) That such stations are authorizedin the service shown in
Column 5 of the
Table of Frequency Allocations in theband in question;
(2) That harmful interference will notbe caused to services
operating in ac-cordance with the Table of
FrequencyAllocations.
(h) Special provisions regarding theuse of spectrum allocated to
the fixedand land mobile services below 25 MHzby non-Government
stations.
(1) Only in the following cir-cumstances will authority be
extendedto stations in the fixed service to oper-ate on frequencies
below 25 MHz.
(i) With respect to aeronautical fixedstations, only when a
showing can bemade that more suitable facilities arenot
available.
(ii) With respect to fixed stations, ex-cept aeronautical fixed
stations, onlyto:
(A) Provide communication circuitsin emergency and/or disaster
situa-tions, where safety of life and propertyare concerned;
(B) Provide standby and/or backup fa-cilities to satellite and
cable circuitsused for international public cor-respondence;
(C) Provide standby and/or backupcommunications circuits to
regular do-mestic communication circuits whichhave been disrupted
by disasters and/oremergencies;
(D) Provide communication circuitswholly within the State of

protection for as-signments made pursuant to para-graphs (h)
(1)(ii) and (2) of this section;this results in the following
con-straints upon the circuits/assignments.
(i) The Commission will not acceptresponsibility for protection
of the cir-cuits from harmful interference causedby foreign
operations.
(ii) In the event that a complaint ofharmful interference
resulting from op-eration of these circuits is receivedfrom a
foreign source, the offendingcircuit(s) must cease operation on
theparticular frequency concerned.
(iii) In order to accommodate the sit-uations described in
paragraphs (h)(3)(i) and (ii) of this section, equipmentsshall be
capable of transmitting and re-ceiving on any frequency in the
bandsassigned to the particular operationand capable of immediate
changeamong the frequencies.
§ 2.103 Government use of non-Govern-ment frequencies.
Government stations may be author-ized to use non-Government
fre-quencies in the bands above 25 MHz ifthe Commission finds that
such use isnecessary for coordination of Govern-ment and
non-Government actitivies:Provided, however, That:
(a) Government operation on non-Government frequencies shall
conformwith the conditions agreed upon by theCommission and the
National Tele-communications and Information Ad-ministration (the
more important ofwhich are contained in paragraphs (b),(c), and (d)
of this section);
(b) Such operations shall be in ac-cordance with Commission
rules gov-erning the service to which the fre-quencies involved are
allocated;
(c) Such operations shall not causeharmful interference to
non-Govern-ment stations and, should harmful in-terference result,
that the interfering
Government operation shall imme-diately terminate; and
(d) Government operation has beencertified as necessary by the
non-Gov-ernment licensees involved and thiscertification has been
furnished, inwriting, to the Government agencywith which
communication is required.
§ 2.104 International Table of Fre-quency Allocations.
(a) The International Table of Fre-quency Allocations (columns
1, 2 and 3of § 2.106) is included for informationalpurposes
only.
(b) Regions. To facilitate the inter-national allocating of the
radio spec-trum, the International Telecommuni-cation Union (ITU)
has divided theworld into three Regions 1 as shown inFigure 1 and
described below:
(1) Region 1 includes the area limitedon the East by line A
(lines A, B and Care defined below) and on the West byline B,
excluding any of the territory ofIran which lies between these
limits. Italso includes that part of the territoryof Turkey and the
Union of Soviet So-cialist Republics (U.S.S.R.) lying out-side of
these limits, the territory of theMongolian Peoples’ Republic, and
thearea to the North of the U.S.S.R. whichlies between lines A and
C.
(2) Region 2 includes the area limitedon the East by line B and
the West byline C.
(3) Region 3 includes the area limitedon the East by line C and
on the Westby line A, except the territories of theMongolian
Peoples’ Republic, Turkey,the territory of the U.S.S.R. and thearea
to the North of the U.S.S.R. Italso includes that part of the
territoryof Iran lying outside of those limits.
(4) The lines A, B and C are defined asfollows:
(i) Line A extends from the NorthPole along meridian 40° West of
Green-wich to parallel 40° North; thence bygreat circle arc to the
intersection ofmeridian 60° East and the Tropic ofCancer; thence
along the meridian 60°East to the South Pole.

(iii) Services, the names of which areprinted in ‘‘normal
characters’’ [exam-ple: Mobile]; these are called ‘‘second-ary’’
services.
(2) Additional remarks pertaining toan allocation are printed in
‘‘normalcharacters’’ [example: MOBILE exceptaeronautical
mobile].
(3) Permitted and primary serviceshave equal rights, except
that, in thepreparation of frequency plans, the pri-mary services,
as compared with thepermitted services, shall have priorchoice of
frequencies.
(4) Stations of a secondary service:(i) Shall not cause harmful
inter-
ference to stations of primary or per-mitted services to which
frequenciesare already assigned or to which fre-quencies may be
assigned at a laterdate;
(ii) Cannot claim protection fromharmful interference from
stations of aprimary or permitted service to whichfrequencies are
already assigned ormay be assigned at a later date;
(iii) Can claim protection, however,from harmful interference
from sta-tions of the same or other secondaryservice(s) to which
frequencies may beassigned at a later date.
(5) Where a band is indicated in afootnote of the International
Table(i.e., columns 1, 2, and 3 of § 2.106) as al-located to a
service ‘‘on a secondarybasis’’ in an area smaller than a Re-gion,
or in a particular country, this isa secondary service.
(6) Where a band is indicated in afootnote of the International
Table asallocated to a service ‘‘on a primarybasis’’, or ‘‘on a
permitted basis’’ in anarea smaller than a Region, or in a
par-ticular country, this is a primary serv-ice or a permitted
service only in thatarea country.
(e) Additional allocations. (1) Where aband is indicated in a
footnote of theInternational Table as ‘‘also allocated’’to a
service in an area smaller than aRegion, or in a particular
country, thisis an ‘‘additional’’ allocation, i.e., anallocation
which is added in this coun-try area or in this country to the
serv-ice or services which are indicated inthe International
Table.
(2) If the footnote does not includeany restriction on the
service or serv-ices concerned apart from the restric-
tion to operate only in a particulararea or country, stations of
this serviceor these services shall have equality ofright to
operate with stations of theother primary service or services
indi-cated in the International Table.
(3) If restrictions are imposed on anadditional allocation in
addition to therestriction to operate only in a par-ticular area or
country, this is indi-cated in the footnote of the Inter-national
Table.
(f) Alternative allocations. (1) Where aband is indicated in a
footnote of theInternational Table as ‘‘allocated’’ toone or more
services in an area smallerthan a Region, or in a particular
coun-try, this is an ‘‘alternative’’ allocation,i.e., an allocation
which replaces, inthis area or in this country, the alloca-tions
indicated in the InternationalTable.
(2) If the footnote does not includeany restriction on stations
of the serv-ice or services concerned, apart fromthe restriction to
operate only in a par-ticular area or country, these stationsof
such a service or services shall havean equality of right to
operate withstations of the primary service or serv-ices, shall
have an equality of right tooperate with stations of the
primaryservice or services, indicated in theInternational Table, to
which the bandis allocated in other areas or countries.
(3) If restrictions are imposed on sta-tions of a service to
which an alter-native allocation is made, in additionto the
restriction to operate only in aparticular country or area, this is
indi-cated in the footnote.
(g) Miscellaneous provision. (1) Whereit is indicated that a
service may oper-ate in a specific frequency band subjectto not
causing harmful interference,this means also that this service
can-not claim protection from harmful in-terference caused by other
services towhich the band is allocated underChapter III of the
international RadioRegulations.
(2) Except if otherwise specified in afootnote, the term fixed
service does notinclude systems using ionospheric scat-ter
propagation.

§ 2.105 United States Table of Fre-quency Allocations.
(a) The United States Table of Fre-quency Allocations (columns 4
through7 of § 2.106) is based on the Inter-national plan for Region
2 because therelevant area of jurisdiction is locatedprimarily in
Region 2 1 (i.e., the 50States, the District of Columbia,
theCaribbean insular areas 2 and some ofthe Pacific insular areas
3).4 Becausethere is a need to provide radio spec-trum for both
Federal government andnon-Federal government operations,the United
States Table is divided intothe Government Table of
FrequencyAllocation and the Non-GovernmentTable of Frequency
Allocations. TheGovernment plan, as shown in column4 of § 2.106, is
administered by the Na-tional Telecommunications and Infor-mation
Administration (NTIA) 5,whereas the non-Government plan, asshown in
column 5 of § 2.106, is adminis-tered by the Federal
CommunicationsCommission (FCC) 6
(b) In the United States, radio spec-trum may be allocated to
either Gov-ernment or non-Government use exclu-sively, or for
shared use. In the case ofshared use, the type of service(s)
per-mitted need not be the same [e.g., Gov-ernment FIXED,
non-Government MO-BILE]. The terms used to designate
categories of service 7 in columns 4 and5 of § 2.106, correspond
to the terms em-ployed by the International Tele-communication
Union (ITU) in theinternational Radio Regulations.
(c) Categories of services. (1) Any seg-ment of the radio
spectrum may be al-located to the Government and/or non-Government
sectors either on an exclu-sive or shared basis for use by one
ormore radio services. In the case wherean allocation has been made
to morethan one service, such services are list-ed in the following
order:
(i) Services, the names of which areprinted in ‘‘capitals’’
[example:FIXED]; these are called ‘‘primary’’services;
(ii) Services, the names of which areprinted in capitals between
obliquestrokes [example: /RADIOLOCATION/];these are called
‘‘permitted services’’;
(iii) Services, the names of which areprinted in ‘‘normal
characters’’ [exam-ple: Mobile]; these are called ‘‘second-ary’’
services.
(2) Permitted and primary serviceshave equal rights, except
that, in thepreparation of frequency plans, the pri-mary services,
as compared with thepermitted services, shall have priorchoice of
frequencies.
(3) Stations of a secondary service:(i) Shall not cause harmful
inter-
ference to stations of primary or per-mitted services to which
frequenciesare already assigned or to which fre-quencies may be
assigned at a laterdate.
(ii) Cannot claim protection fromharmful interference from
stations of aprimary or permitted service to whichfrequencies are
already assigned ormay be assigned at a later date; and
(iii) Can claim protection, however,from harmful interference
from sta-tions of the same or other secondaryservice(s) to which
frequencies may beassigned at a later date.

the non-Gov-ernment sector, respectively, has noaccess to that band
except as providedfor by §2.102.
(2) The Government allocation plan,given in column 4, is
included for infor-mational purposes only.
(3) In the case where there is a par-enthetical addition to an
allocation inthe United States Table [example:FIXED-SATELLITE
(space-to-earth)],that service allocation is restricted tothe type
of operation so indicated.
(4) The following symbols are used todesignate footnotes in the
UnitedStates Table:
(i) Any footnote not prefixed by a let-ter, denotes an
international footnote.Where such a footnote is applicable,without
modification, to the UnitedStates Table, the symbol appears inthe
United States Table (column 4 or 5)and denotes a stipulation
affectingboth the Government and non-Govern-ment plans.
(ii) Any footnote consisting of theletters US followed by one or
more dig-its, e.g., US, denotes a stipulation af-fecting both the
Government and non-Government plans.
(iii) Any footnote consisting of theletters NG followed by one
or more dig-its, e.g., NG1, denotes a stipulation ap-plicable only
to the non-Governmentplan (column 5).
(iv) Any footnote consisting of theletter G following by one or
more dig-its, e.g., G1, denotes a stipulation ap-plicable only to
the Government plan(column 4).
(5) Column 6 provides a reference toindicate which Rule part(s)
(e.g., Pri-vate Land Mobile Radio Services, Do-mestic Public Land
Mobile Radio Serv-ices, etc.) are given assignments withinthe
allocation plan specified in column5 for any given band of
frequencies. Theexact use that can be made of anygiven frequency or
frequencies (e.g.,channelling plans, allowable emissions,etc.) is
given in the Rule part(s) so in-dicated. The Rule parts in this
columnare not allocations. They are providedfor informational
purposes only.
(6) Column 7 is used to denote certainfrequencies which have
national and/orinternational significance.
