Emergency Mil Radios

[Sandy W5TVW]

        When I was in avionics, and I'm sure the "band" is probably the
same, the UHF sets tuned from 225.0 to 399.9 Mhz.  At that time in
100 Khz steps, AM.  I think it moves in 50 Khz steps now.

        121.5 and 243.0 are the "guard" or emergency calling channels and most
of the survival radios we had operated on those frequencies.  The later sets
we got did just 243.0 Mhz.  This was some years ago.

        This was Air Force.  The Navy did the same thing on the other side of
the base I was last.  I do know the ARMY choppers/fixed wing aircraft
used FM for air to ground in the 30-75 Mhz band commonly used by
the ground troops' field radios.  Like the old PRC-25.  I have no idea
what the Army used for an "emergency" channel in that band.
