The British Army Clansman HF 250 Watt RF Power Amplifier. These amplifiers were designed to upgrade the standard VRC-321 to a VRC-322. The amplifier boosts the output power of the Clansman VRC-321 vehicle radio station to 250 Watts. It can also be used with other HF radios having an output power of 20-40 Watts.
The RF amplifier has been designed and developed by MEL Communications Ltd in Crawley, England for mobile or static use. It is primarily designed as an High Power 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.
Frequency range 1.5 to 30 MHz. Power output, High Power 300 Watt PEP (SSB), 250 Watt CW, Low Power 40 Watt PEP (SSB), 25 Watt CW. Beta light illumination is provided to enable the meter and Setting Switches to be read in the dark.
The equipment operates from 28 VDC power supply which can have a wide variation in nominal voltage
