OK, I found Q7 was very leaky, I changed it to a 2sc2999 and put in schottky diodes in place of D4, 6, and 7. I tested the caps around the audio chip but they were all good, looks like someone replaced them.
When I fired it up I had static with the radio on and the NB off, much louder than before. I still heard nothing with the NB or ANL on. I decided to align the receive using my HP 8656B and Kikusui scope. I followed the alignment instructions for a Cobra 29. I tried to use my VTVM but could get no reading.
AFTER the alignment I now here NO static in ANY NB position. I could hear the signal generator at 6 uV but no static at all. I have a Grant XL and a Connex 3300HP-ZX and both of them I could hear static plus the 1kHz tone down to 1 uV. Any ideas where to go from here?
