I have a TS-700A on my bench, it has no receive audio on FM mode. SSB works fine. In FM mode, testing with simplex, the S meter shows full deflection, with white noise in the speaker, but absolutely no modulation in the received audio. The RXF pin on the IF FM board shows a good amplitude signal when I send a test transmission from another radio on the frequency. It doesn’t get much further than there. One thing I noted was that the 10.245MHz crystal oscillator associated with Q3 doesn’t seem to be oscillating, at least according to my Tektronix 75MHz scope using AC coupling. I’ve replaced Q3 and X1. Can you recommend how to proceed?
