RA17L Government Communications Receiver
This set is generally considered (along with the Collins R390A) to be the finest, most sensitive general communications receiver ever to enter service from the tube era. Incorporating Dr Trevor Wadley's famous 'Wadley Loop' circuit, this superbly made instrument firmly established Ray Brown and Calder Cunningham in the defence electronics business.
It is a cast aluminium monster with a plethora of controls for finding the right station. Yet the tuning scale is accurate to 5kHz and drift is almost non-existant. My particular example dates from November 1961 and takes a proud place in my collection.
