The radio receives great. No TX on AM and SSB. No TX light. Not sure it is a PLL problem. I also have no voice output on PA. I do have sound on pa. It seems like when I key the mic. it is not switching. Yes I tried another mic. Q24 carrier oscillator is good. D27, 28, 29 Good. Q38 switch is good. X2 removed and tested good but I am showing no frequency at X2 but show 10.6975 at TP3. Q503 is good. And I do not think it is Q36 or Q37 modulation amp because that would not have anything to do with the TX light not coming on. Or would it? What have I missed? Thanks.
