Plessey B-47 36-60 MHz FM transceiver

Created 8th November 2010

The Plessey B-47 is a military transceiver used by Australian Army during the Vietnam War
it could operate FM from 36-60 MHz with about 1 watt output.
The radio was classed as a "portable" transceiver with remote harnesses and control units.
The B-47 operated from a 12v DC supply.
I used the B-47 for 6 metre activity between 52-54 MHz. It was also good for looking for TV dx indicators
as it was rather wideband, you easily listen for video and sound carriers from TV ch.0 and ch.1 transmitters,
including NZ TV ch.1.
As these were valve based, the trick to making the receiver more sensitive, was replace the front-end
valves with a MOSFET front-end.
