UK/VRC-321 and -322
The UK/VRC-321 replaced both the C11 and C13 front line HF stations and the D11/D13 long range truck mounted station, in the latter case being issued with a 250 watt output amplifier and being called UK/VRC-322. The UK/VRC-321 is a mobile HF radio providing communications beyond horizon range for vehicles and if dismounted for fixed sites. The system is modular comprising the radio itself, an antenna tuner TURF-25W, an interference filter SURF-25W and when used as a VRC-322 the Amplifier 250W and TURF-250W. The VRC-321 was most commonly installed in FFR land rovers and in command and reconnaissance vehicles suh as SULTAN and SCORPION where operation over extended ranges was expected. The set is specifically designed for radio-teleprinter service and a modem called “Adapter Telegraph Radio” or ATR was provided for that purpose.
