I see TX power overshoot when there is too much audio drive. The 5th bar should be flashing not solid on the ALC meter. Also, do a TX GAIN calibration procedure from the K3 Utility.
My KPA500 has endured some massive peak power overshoots without destruction (1200w) before I readjusted things. I also use an LP-100, and it seems to have an extremely sensitive peak mode. 73 Eric WD6DBM On Fri, Jan 11, 2019, 1:21 PM John Simmons <jasimm...@pinewooddata.com wrote: > I have a 6xxx K3 (not S).
