I just realized you said 30m. Why are you running the amplifier ("max power") on 30m??

I am experiencing a new problem for me, with my KAT 500. So far I've noticed this issue on 30M. I am using a dipole cut only for 30M with an SWR of 1.2 to 1.3 max SWR across the band. I “trained the tuner” at 20khz segments on 30M. Setup is K4D, KAT 500 & KPA 500. Win 10 pc. Running CW, I can start transmitting and all is fine- my LP100A is showing 1.2 SWR and am getting max power out of the radio. Then all of sudden the SWR jumps to >9.0. The KAT starts chattering and finds a new match. But if I start transmitting again – pwr out is only about 10 W at that new match, and eventually the tuner becomes untuned again. Sometimes, it will then hold the tune but still only getting abt 9-10w power out. The issue occurs with KPA500 both on and off. Does this sound like a KAT 500 problem or maybe an RFI problem. 73 Paul w2eck
