Default Re: Racal RA17L BFO behaviour

Good evening Paolo and welcome to the Forum. Several regular contributors are familiar with the RA17 and its derivatives, and I'm sure you will receive help with your problem.

Without being familiar with this receiver, if the BFO is generating harmonics then its output must be badly distorted. The usual suspect components such as anode and screen resistors, feedback and cathode bias components should come under suspicion.

Good luck!
