RACAL RA-17 Receiver - one of the best all - tube communication receivers ever built.

A short video of the classic RACAL RA-17 communications receiver widely used by militaries around the World. This is an all valve (tube) design with outstanding frequency stability thanks to the "Wadley Loop".
Enjoy

Brilliant receiver. Worked on it and used it when I was an apprentice. We used them for RTTY over long distances together with the companion 1 KW transmitter.
Uses the Wadley loop, that gives it great stability.
