Alan, Rocky's I/Q reversal toggles both the tx and rx. The RX_REV reverses only the receiver. Without the jumper, one or the other is always wrong in Rocky. No...

Ok, I pulled R16, and it still reads 5v at pin 1. R16 measures out at 10k as it should, but with it pulled there is very little voltage at pin 2. The current,...
