Clansman UK/VRC-321

The Clansman UK/VRC-321 Radio set was also used for rear link communications up to Brigade level and administrative radio nets. In the British Army it provided a useful back up or "guard net", to the VHF radio nets which were prone to jamming by the enemy. The Clansman UK/VRC-321 is a HF Radio which uses USB/AM andor CW giving an RF output 20 - 30 Watts. the set was Manufactured by MEL, Of Crawley in Sussex and replaced the Larkspur SR C13 and C11 R210 HF Vehicle Stations. These were in service between Ca 1955 and 1978 and used primarily Amplitude Modulation (AM) and Continuous Wave (CW) (Morse). (Although SSB versions of the C11 R210 became available, following the development of SSB). The introduction of Clansman HF Radio therefore saw the adoption of SSB as the standard modulation type for use in the British Army due to its increased efficiency, while AM was provided primarily for interoperability between Larkspur and Clansman Radios after Unit Clansmanisation.
