95.1 The General Mobile Radio Service (GMRS).
(a) The GMRS is a land mobile radio service available to persons for short-
distance two-way communications to facilitate the activities of
licensees and their immediate family members. Each licensee manages a
system consisting of one or more stations.
(b) [Pertains only to the 218-219 MHz Service, formerly known as the
Interactive Video and Data Service (IVDS).]
95.3 License required.
Before any station transmits on any channel authorized in the GMRS from
any point (a geographical location) within or over the territorial limits
of any area where radio services are regulated by the FCC, the responsible
party must obtain a license (a written authorization from the FCC for a
GMRS system).
95.5 License eligibility.
(a) An individual (one man or one woman) is eligible to obtain, renew
and have modified a GMRS system license if that individual is 18 years
of age or older and is not a representative of a foreign government.
(b) A non-individual (an entity other than an individual) is ineligible
to obtain a new GMRS system license or make a major modification to an
existing GMRS system license.
(c) A GMRS system licensed to a non-individual before July 31, 1987, is
eligible to renew that licenses and all subsequent licenses based upon it
if:
(1) The non-individual is a partnership and each partner is 18 years of
age or older; a corporation; an association; a state, territorial,
or local government unit; or a legal entity;
(2) The non-individual is not a foreign government; a representative of
a foreign government; or a federal government agency; and
(3) The licensee has not been granted a major modification to its GMRS
system.
95.7 Channel sharing.
(a) Channels or channel pairs (one 462 MHz frequency listed in 95.29(a) of
this part and one 467 MHz frequency listed in 95.29(b) of this part) are
available to GMRS systems only on a shared basis and will not be assigned
for the exclusive use of any licensee. All station operators and GMRS
system licensees must cooperate in the selection and use of channels to
reduce interference and to make the most effective use of the facilities.
(b) Licensees of GMRS systems suffering or causing harmful interference are
expected to cooperate and resolve this problem by mutually satisfactory
arrangements. If the licensees are unable to do so, the FCC may impose
restrictions including specifying the transmitter power, antenna height,
or area or hours of operation of the stations concerned. Further, the use
of any frequency at a given geographical location may be denied when, in
the judgment of the FCC, its use in that location is not in the public
interest; the use of any channel or channel pair may be restricted as to
specified geographical areas, maximum power, or other operating
conditions (see 95.71(d)).
95.21 GMRS system description.

95.637 Modulation standards.
(a) A GMRS transmitter that transmits emission types F1D, G1D, or G3E
must not exceed a peak frequency deviation of plus or minus 5 kHz.
A GMRS transmitter than transmits emission type F3E must not exceed
a peak frequency deviation of plus or minus 5 KHz. A FRS unit that
transmits emission type F3E must not exceed a peak frequency
deviation of plus or minus 2.5 KHz, and the audio frequency response
must not exceed 3.125 KHz.
(b) Each GMRS transmitter, except a mobile station transmitter with a power
output of 2.5 W or less, must automatically prevent a greater than
normal audio level from causing overmodulation. The transmitter also
must include audio frequency low pass filtering, unless it complies
with the applicable paragraphs of 95.631 (without filtering). The
filter must be between the modulation limiter and the modulated stage
of the transmitter. At any frequency (f in kHz) between 3 and 20 kHz,
the filter must have an attenuation of at least 60 log10 (f/3) dB
greater than the attenuation at 1 kHz. Above 20 kHz, it must have an
attenuation of at least 50 dB greater than the attenuation at 1 kHz.
(c) When emission type A3E is transmitted, the modulation must be greater
than 85% but must not exceed 100%. Simultaneous amplitude modulation
and frequency or phase modulation of a transmitter are not permitted.
(d) [Pertains only to the Citizens Band Radio Service.]
(e) [Pertains only to the Family Radio Service.]
95.639 Maximum transmitter power.
(a) No GMRS transmitter, under any condition of modulation, shall exceed:
(1) 50 W carrier power (average TP during one unmodulated RF cycle)
when transmitting emission type A1D, F1D, G1D, A3E, F3E or G3E.
(2) 50 W peak envelope TP when transmitting emission type H1D, JID,
R1D, H3E, J3E or R3E.

CERTIFICATION REQUIREMENTS

can result in a violation of the rules shall be accessible from the
transmitter operating panel or from the exterior of the transmitter
enclosure.

Radio and Medical Implant Communications Services.]
95.651 Crystal control required.
All transmitters used in the Personal Radio Services must be crystal
controlled, except an R/C station that transmits in the 26-27 MHz
frequency band, a FRS unit, a LPRS unit, or a MICS transmitter.
95.653 Instructions and warnings.
(a) A user's instruction manual must be supplied with each transmitter
marketed, and one copy (a draft or preliminary copy is acceptable
provided a final copy is provided when completed) must be forwarded to
the FCC with each request for certification.
(b) The instruction manual must contain all information necessary for the
proper installation and operation of the transmitter including:
(1) Instructions concerning all controls, adjustments and switches
that may be operated or adjusted without resulting in a violation
of the rules.
(2) Warnings concerning any adjustment that could result in a
violation of the rules or that is recommended to be performed by
or under the immediate supervision and responsibility of a person
certified as technically qualified to perform transmitter
maintenance and repair duties in the private land mobile services
and fixed services by an organization or committee representative
of users of those servIces.
(3) Warnings concerning the replacement of any transmitter component
(crystal, semiconductor, etc.) that could result in a violation of
the rules.
(4) For a GMRS transmitter, warnings concerning licensing requirements
and information concerning license application procedures.
95.655 Frequency capability.
(a) No transmitter will be certificated for use in the CB service if it is
equipped with a frequency capability not listed in 95.625, and no
transmitter will be certificated for use in the GMRS if it is equipped
with a frequency capability not listed in 95.621, unless such
transmitter is also certificated for use in another radio service for
which the frequency is authorized and for which certification is also
required. (Transmitters with frequency capability for the Amateur
Radio Services, Military Affiliate Radio System and Civil Air Patrol
will not be certificated.)
(b) All frequency determining circuitry (including crystals) and
programming controls in each CB transmitter and in each GMRS
