Well, kind of hoping someone out there knows something about the FM1000 circuitry. Am I correct in my assumption that the trimmer on the detector can should adjust the oscillator frequency of the can to the same frequency as the IF (9.1MC) and the FM1000 combines the two and selects the null heterodyne to remove the IF carrier leaving the FM "signal"? I am not too bright at this but trying to understand. As indicated above, adjusting per the proceedure does not provide a zero beat. Adjusting does not change the detector oscillator frequency which remains at 10.4 MC. Need some major education here!
