Ok. The radio receives fine.......AFTER...I key the mic. And that's only majority of the time. There are times that it won't come back after I key up. I have changed TR35 and D43 thinking it was the switching trans. I am thinking it's the AGC because when the RX is out, it's not out completely. It's extremely muffled. Very strong signals come through but they too are very muffled. Because of that theory, I changed TR10, D5 thru D10. Any ideas?
