The AN/PRC-25 (NSN 5820-01-857-0934)
is a compact, lightweight, tactical VHF, solid state manpack radio set.
Prototypes of this set were initially tested in 1959. After some modifications,
initial distribution began in 1962. It is reported that more than 130,000 sets
were produced. Although mainly designed for manpack use, the PRC-25 can be
employed in a vehicular mounted configuration using standard VRC-12 family
equipment. This includes an MT-1029/VRC tray with an AM-2060A/GRC
Amplifier/Power Supply adapter. The AM-2060 is sometimes referred to as
Amplifier-Power Supply Group, OA-3633/GRC. Throughout the years, several other
accessories were also designed for this radio set.
Note: Although this set is deemed as solid state, it is important to note that
there is one final transmitter power amplifier tube (type 2DF4) employed in the
PRC-25. Plate, screen-grid & bias voltages are produced by a dc-to-dc converter.
The filament voltage is provided by the battery.
