Man I can’t believe it… It was D36 could have sworn I checked that I mean it’s the diode closest to the test point. I have been doing this to long to make that mistake. Sorry if I wasted your time.
Diode is replaced and SSB is working again.
Thank you for your time and thank you for asking me...
I know what I did I put 12 volts on test point 6.. just for a millisecond till the current blow the fuse in the meter I just truly cant find what got damaged because of it.
I can transmit and be heard the talk back still works. I just cant hear others. In AM mode I can hear fine checking the out put of IC8 with a Oscilloscope in SSB mode there is nothing there but in AM mode there is a signal. I have checked what I can see from the schematic as directly related...
