[ICOM] 12V base station that can be operated on the GMRSFrequencies

[Kay W. Hargis]

Hi Buck..

Very helpful and useful information.  I am sure this has enlightened
many on the reflector.  I certainly appreciate the research you have
done and your suggestions.

Thank you very much

73, Kay

You might want to check eBay or with various commercial radio houses.
You may find they will have some used radio that they will setup for you
that will be type accepted.  Several hams around here have dug up old
commercial radios and reprogrammed them for GMRS or other public service
frequencies they are authorized to use.  

It is illegal to use Amateur radio equipment for GMRS transmissions.
Local organizations in this state which used to not worry about the use
of converted amateur radios on their service have now started
discouraging the practice and some have started requiring inspection of
the radios volunteers are using to insure that they comply with the
rules.  Violation of the rules puts not only the operator at jeopardy,
but also any related entity in which the radios are used.

Here are a few excerpts from the rules.

95.129 Station equipment.

Every station in a GMRS system must use transmitters the FCC has
certificated for use in the GMRS. Write to any FCC Field Office to find
out if a particular transmitter has been certificated for the GMRS. All
station equipment in a GMRS system must comply with the technical rules
in Part 95.

95.603 Certification required.

(a) Each GMRS transmitter (a transmitter that operates or is intended to
operate at a station authorized in the GMRS) must be type accepted.

95.621 GMRS transmitter channel frequencies.

(a) The GMRS transmitter channel frequencies (reference frequencies from
which the carrier frequency, suppressed or otherwise, may not deviate by
more than the specified frequency tolerance) are

462.5500, 462.5625, 462.5750, 462.5875, 462.6000, 462.6125, 462.6250,
462.6375, 462.6500, 462.6625, 462.6750, 462.6875, 462.7000, 462.7125,
462.7250, 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750,
467.7000 and 467.7250.

Note: Certain GMRS transmitter channel frequencies are authorized only
for certain station classes and station locations. See Part 95, Subpart
A.

(b) Each GMRS transmitter for mobile station, small base station and
control station operation must be maintained within a frequency
tolerance of 0.0005%. Each GMRS transmitter for base station (except
small base), mobile relay station or fixed station operation must be
maintained within a frequency tolerance of 0.00025%.

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 type accepted 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 transmitter
must be internal to the transmitter and must not be accessible from the
exterior of the transmitter operating panel or from the exterior of the
transmitter enclosure.



Good luck.  I hope you find what you need.
