Yeah, I need to go buy a new DMM as I have no way to connect the RF
probe to my current DMM.

However, I just checked the ALC circuit and found that VPWR is reading
high.  It is reading 4.9V on pin 2 of U8 (control board) during key
down.  According to the manual, this indicates a potential problem in
the RF detector stage.  I'm going to poke around the detector a bit
more and see if I can find any problems there.
