OK, I have un-built the kit back to before the KPA3 was installed. It still fails the 5 watt Transmitter Gain Calibration Procedure. I cannot detect any RF out. Perhaps unbuilding the kit creates it's own set of problems, but this test worked "on the way up." It also worked with the PA installed. It stopped working when I installed the sub-receiver. That is now no longer installed.
