Clansman UK VRC-321 HF system has been designed and
developed by MEL Communications Ltd in Crawley, England for mobile or static
use. It is primarily designed as an HF vehicle
station for mobile ground-wave operation, but can also be used as a ground
station or for sky-wave operation over long distances. With the addition of a
250 Watt RF amplifier the station becomes a VRC-322,
which is available elsewhere on this website.
