Extensive Definition

Clansman is the name of a radio system used by the British Army.
Clansman was developed by SRDE in the 1970s, to satisfy a General Staff Requirement (GSR) laid down in 1965 . Built by Racal, MEL and Plessey, it represented a considerable advance over existing radios being offered to the Armed Forces at the time. It replaced the aging Larkspur radio system, proving to be more flexible, reliable and far lighter than the previous system. The technological advances achieved in the design of Clansman allowed the introduction of Single Sideband (SSB) operation and narrowband Frequency Modulation (NBFM) to field-level communications for the first time.
Clansman has been in use by British forces since the early 1980s in most recent UK military operations, the first active use being by 2nd Bn the Parachute Regiment in the Falkland Islands operation in 1982. It is in the process of being replaced by the new digital Bowman communication system.

Family

The Clansman family consists of 9 main radio units, 3 of which are carried on vehicles, the other 6 on the back, across the chest, or other such places on a foot soldier.
Models are designated "UK/PRC" or "UK/VRC", which stand for "United Kingdom / Personal Radio Communications" and "United Kingdom / Vehicle Radio Communications" respectively.
The most common are the:
  • UK/PRC 349 - An intra-section level portable VHF FM transceiver. Built by Racal BCC. RF power output is 0.25 watts. Units supplied to the British Army operate in the 37 - 46.975 MHz range, voice (FM) transmission Mode. A high power (2 Watts) output version was also available and any 10 MHz block in the range 30 - 76 MHz could be supplied. The PRC349 was an afterthought in the Clansman family, being added to the range in 1972.
  • UK/PRC 351/352 - An intra-platoon level backpack VHF FM transceiver. Built by Racal. The PRC 351 has 4 watt RF power output, and operates in 30-75.975 MHz range with possible 1840 channels. The PRC 352 is identical, with the addition of a 20 watt RF amplifier and can be used as a ground station.
  • UK/VRC 353 - A vehicle-mounted VHF FM transceiver built by Marconi Space and Defence Systems. The frequency range was the same as the 351/352 with power settings up to 50 W. Antenna systems are provided to provide improved performance in semi-static situations such as an elevated broadband vertical dipole mounted on an 8 metre mast.
The VRC is also capable of data transmission and when used in conjunction with an add-on unit (Digital Master Unit)provides a medium level secure speech network.
  • UK/PRC 320 - An intra-company level HF/USB/AM/CW transceiver. Built by Plessey. Operates in 2-29.9999 MHz range with possible 280,000 channels. RF power output is a selectable 3 or 30 watts. The PRC 320 can be used as a backpack or vehicular radio with a number of different antennas available for different circumstances and needs. It can also be used as a ground station with a dipole antenna attached to two masts for long-range communication (with the bounce effect of the ionosphere giving world-wide communication given optimum frequency and time of day).
  • UK/VRC 321 A vehicle-borne High Frequency transmitter/receiver used for inter company communications outside of the normal working range of the VHF forward area nets, and for rear link communications to Brigade level.
Modes of operation are USB/AM/CW. RF output 20 - 30 Watts. Manufactured by MEL, Crawley, Sussex.
  • UK/VRC 322 A VRC321 station with an additional 300 Watt pep linear amplifier (ARF 250W) and appropriate high power antenna tuning unit (TURF 250). Manufactured by MEL, Crawley, Sussex.
  • UK/PRC 344 - A forward air control UHF AM transceiver. Built by Plessey. Operates in 225-399.9 range with 50 kHz steps for possible 3500 channels. RF power output is rated at 2.5 watts.
