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.
