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.
