1、UK/PRC320 Clansman and PRC320/1 HF/SSB Manpack Transceivers UK/PRC320 is a lightweight HF/SSB radio station designed as part of the British Armys Clansman range of radio equipments for combat use throughout theworld. It is particularly suitable for use by long-range patrols or special forces because

2、 of its sky-wave range performance and hand generator system. The equipment operates in the 2 to 30 MHz band with 100 Hz channel spacing, which gives a choice of 280 000 frequencies. Selection is by decade knobs which control a micro-miniature synthesiser locked to a temperature compensated referenc

3、e oscillator, giving a high order of stability under all environmental conditions. The PRC320 provides SSB (USB), AM, CW (wide) and CW (narrow) facilities. Speech processing and automatic level control are employed to provide whisper speech facilities and a high mean output power. A transmitter outp

4、ut power of 30 W PEP working into a 2.4 m whip antenna gives the PRC320 a ground-wave communications range in excess of 40 km by day under normal conditions. The PRC320 is suitable for use as a ground station, working into static ground- or sky-wave antennas. Working into a dipole or end-fed antenna

5、, sky-wave communications at ranges from 50 to 2000 km or greater can be achieved. This range performance is due in part to the high grade receiver and high efficiency manual antenna tuning unit (ATU) which is integral with the transmitter/receiver unit. The radio is carried on the operators back an

6、d allows him full use of his weapons. It is powered by rechargeable 24 V Ni/Cd batteries of 1 or 3.3 Ah capacity. Alternatively, the radio can be powered by a hand generator system with a 1 Ah battery, and can be operated remotely if required at distances up to 3 km. With its manpack carrier and bat

7、tery the PRC320 can be used as a clip-in vehicle installation. A vehicle-mounted antenna is used and the battery is float-charged by a DC charging unit from the vehicle supply. PRC320/1 is similar in appearance and built to the same standard as the PRC320 but provides LSB and USB, compatible AM and

8、CW (wide) facilities. Channel spacing is 1 kHz providing 28 000 channels. The PRC320-100 or PRC320/1-100 100 W HF/SSB vehicle stations use the manpack station in its clip-in role to drive a 100 W amplifier with automatic ATU. The VRC320/2 30 W HF/SSB vehicle station is a vehicle variant in repackage

9、d form which provides the same facilities as the PRC320/1 and has an automatic ATU. The VRC320/2-100 100 W HF/SSB vehicle station utilises RT320/2 plus 100 W amplifier with automatic ATU. Status Introduced in 1976, since when more than 15 000 sets have been manufactured. Part of the Clansman range.
