Hello Brian and Stan.

Thank you for confirming my measurements, couldn't imagine it working any
other way. I can cross VFO2 off the possible cause list...

Brian.

PS If I feed 2.5mhz into the set via antenna socket from a signal generator
the set receives it at 2.5mhz. If I tune the sig gen to 2.6mhz, the RA17
receives at 2.4 (2.7/2.3; 2.8/2.2; 2.4/2.6) etc. Any suggestions on the
cause appreciated. It receives nothing else.


The first thing I would check is the local oscillator input to the second
mixer. It should be 37.5MHz at several volts. It can be checked on test
point 3 (I assume you have a circuit).
