produced as add-ons such as MEROD, TDED and Kipling. Clansman HF sets continued in use by the UK's Cadet Forces until c. 2015. Many of the sets found their way into amateur service after the Clansman system became obsolete. UK/VRC 321 A vehicle-borne high-frequency (HF) transmitter-receiver used for inter-company communications outside of the normal working range of the VHF forward area nets; it can also be used dismounted from a vehicle as a ground station with an external power supply or batteries and antenna system. It was also used for rear link communications up to brigade level and administrative radio nets. The set uses USB/AM or CW with an RF output of 20–30 watts. It was manufactured by MEL at Crawley in Sussex and replaced the Larkspur SR C13 and C11 R210 HF Vehicle Stations. The radio is issued together with ancillaries to make up the operating station, including a power cable, antenna tuner unit, coaxial cables and antenna wires. Other accessories such as the selector unit radio frequency (SURF) were available. The SURF, when tuned, allowed more than one set to be operated from the same position without interfering with each other. The standard antenna tuning unit used with the UK/RT 321 is the Tuning Unit Radio Frequency (TURF) 25 watts. This could be used either attached to the set, or remotely, depending on which antenna configuration was used. UK/VRC 322 A VRC321 station with the addition of a 300 Watt peak envelope power (PEP) linear amplifier (ARF 250W) and appropriate high power antenna tuning unit (TURF 250) manufactured by MEL of Crawley, Sussex.
