Military communications activity can be found in the VHF-Low Band (30-50
MHz) in the following frequency ranges:
30.00-30.55
32.00-32.99
34.00-34.99
36.00-36.99
40.00-41.99
49.61-49.99
Military communications can also be found in the following government
bands mixed in with various govenment agencies communications: 162.00-173.9875
and 406.00-420.00 MHz
VHF-High
Band Bandplans
The primary military-only bands in the VHF high band are 138.00-144.00
and 148.00-150.775. Basic spacing between channel is 25 kHz (USN/USAF). The Army
uses 12.5 kHz spacing in their segments of the band. The primary communications
mode is narrowband FM, but some AM is used by air units of the various services
for tactical air-to-air comms.

UHF
Military Aircraft Bandplan
The military has a BIG (175 MHz) military aircraft band in the 225-400
MHz range. Basic spacing between channels is 25 kHz. You will find not only
oddball spacing (especially in segments of the band with military satellite
uplink/downlink channels), but a variety of modes and bandwidths. The primary
mode in this band is AM, but FM and digital modes are used extensively on
satellite channels.
Some other federal agencies will be found within this frequency range,
notably the Coast Guard, NASA, Federal Aviation Adminstration (FAA), and the
Department of Energy (DOE). All agencies use 243.000 MHz. It is a worldwide
emergency channel. Military satellite uplinks are in the 240-270 MHz range. For
specific satellite downlink frequencies see Satellite
Times, Vol 1, issues 4-6 and Vol 2 issue 1.
