Thanks Mike. Correct me if I'm wrong, when I engage the transmit switch on the station control card, shouldn't the meter readings change? I have another micor here at the office (UHF community repeater) and I inserted the test set into the exciter. This was yesterday when I did this, but I think that readings on all 5 test set settings were 0 until I engaged the transmit switch on the station control card...then got the correct readings throughout the test settings. See, these two aren't behaving the same (course this repeater has its own problem...no audio on repeat...local audio but no repeat audio). Like I mentioned in an earlier reply to a fine fellow, it seems as if the exciter is excited all the time regardless if I attempt to key it up with my handheld or use the station control switch because there are no changes in meter readings (manual says "key the transmitter with the XMTR ON pushbutton on the portable test set" which I did. I also checked the PA with my handheld and it powers just fine by the way. Bob, GMRS WPVV845, Amateur KG4WAD, LMRS WPXC892 Yahoo!
