is a British solid state tactical radio of the Clansman * - series, developed and built
It was primarily used by dismounted troups on compyny and bataillon level, but also can be used as
Only five knobs (that also can be turned with thick mittens) are used to operate it. Four knobs switch the frequency.
The fifth knob has four positions:
Off (On /Off)
Whisper (Increases the microfone sensitivity by the factor 10)
(At the same time reduces the loudness by the factor 10)
Loud (At noisy environment)
Noise on (Squelch is deactivated; also to test if the radio works.)
The radio is carried on the back or at the belt. Battery, short and long rod-antenna and hendset belong to the set.
The antenna socket can be turned, so that the antenna is upright, even whan the operater is lying down.
Handset and headset can be connected simultaneously, so a second operator can listen in.
It can br remote controlled from a distance up to three km, and also can retransmit.
Without HF output it can be used as telephone.
The range with rod antenna is 10 km. An optional HF amplifier can increase the range-
then the name of the radio is PRC-352. Only the use as mobile or fixed station allow the higher output.
Used as manpack, the HF amplifier is deactivated, and the radio serves as a normal PRC-351.
PRC-351 M is the version in the collection. It was uses primarily by the Navy. It is a PRC-51 that can work together with the
Clansman BID System. The BID system is a speech and data encryption that today still is secret.
The PRC-351 is powered by a 24V- Clansman - battery. The radio can be operated by or the battery can be
charged by a handcrank between RT and battery. It also can be powered externally.
The Clansman series is used by the British Army, but also sold to many foreign countries.
