It is recommended
that Members of the Armyradios Group
use the following frequencies for military tactical-FM
radios:
FM Tactical GUARD CHANNEL: 51.0 MHz
(low-power squad radios)
1st ALTERNATE FM 51.6 MHz
2nd ALTERNATE FM 51.4 MHz
3rd ALTERNATE FM 50.4 MHz
51.0 Mhz is recommended for
low-power squad radios, as most of the
AN/PRT-4 AN/PRR-9 sets come equipped with 51.0 Mhz.
It is recommended that any high-power
tactical-FM radios
(more than 10Watts)
be operated within the 50.3 thru 50.6 MHz segment in order to limit
potential
interference within the Pacific DX window of 50.1-50.125 MHz..
Recommended channels, in which all military sets would be
compatible,
are 50.4,
and 50.5
Mhz.
The alternate channels listed are for
use when significant band
openings create significant Interference on 51.0 MHz
Below is the ARRL recommended
band plan for the Amateur Radio Service between 50 and 54 Mhz:
6 METERS (50-54 MHz):
50.0-50.1 CW, beacons
50.060-50.080 beacon sub-band
50.1-50.3 SSB, CW
50.10-50.125 DX window
50.125 SSB calling
50.3-50.6 All modes
50.6-50.8 Non-voice communications
50.62 Digital (packet) calling
50.8-51.0 Radio remote control (20-kHz channels)
51.0-51.1 Pacific DX window
51.12-51.48 Repeater inputs (19 channels)
51.12-51.18 Digital repeater inputs
51.62-51.98 Repeater outputs (19 channels)
51.62-51.68 Digital repeater outputs
52.0-52.48 Repeater inputs (except as noted; 23 channels)
52.02, 52.04 FM simplex
52.2 TEST PAIR (input)
52.5-52.98 Repeater output (except as noted; 23 channels)
52.525 Primary FM simplex
52.54 Secondary FM simplex
52.7 TEST PAIR (output)
53.0-53.48 Repeater inputs (except as noted; 19 channels)
53.0 Remote base FM simplex
53.02 Simplex
53.1, 53.2, Radio remote control
53.3, 53.4 53.5-53.98 Repeater outputs (except as noted; 19 channels)
53.5, 53.6, Radio remote control
53.7, 53.8 53.52-53.9 Simplex
Note: The 6-meter band plan was adopted by the ARRL Board of
Directors
at the July 1991 meeting. The band plan is currently being studied by
the ARRL
Ad Hoc Spectrum Management Committee.
