Whoops, didn't finish that thought. So, my switches appear to be wired up right. In AGC Off, everything works fine. In AGC Fast/Slow, I get very little ADC, and no AGC action.
You mentioned the buffer transistor, the MMBT3904. Any good way to check that? And if I did need to replace it, would a BFR106 be suitable? (I have a couple of those from when I did the power output modifications.
