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.
