Help! I just upgraded my SSB mod to the 2.5 kHz spacing and my BFO has stopped working. It was working after I had completed the mod but my BFO range was slightly high. I was adding additional capacitance to C173 and C174 per various postings on the reflector to attempt to move the BFO spread slightly lower (about .4 kHz). Now my BFO readings are 00000. I have checked the RF probe and it works fine on TP1 and TP3; I have restored the original capacitors to C173 and 174, no luck. Voltage (rms) at pin 6 on U11 was 0.1v; Voltage (rms) on TP2 was 3.1v. I even removed the SSB card and reinstalled the W jumpers and C167, still dead. I have checked for bad solder joints several times, also. I also removed and reinstalled L33 and its parallel resistor, also checked L33 inductance and it was ok. Any suggestions?
