Don, Ok I removed the KPA100 and connected directly to the K2, I also tested with 2 different jumpers, as well as useing the RF in and the AUX connection. All give the same results:
KAT100's relays sound and the K2 shows 1.0-1 swr. Lights on the KAT100 do not light up on tune or TX. K2 reduced power on key up (at 10 watts setting and 5 watt setting). Occasionally I get a High Current message. Current set at 3.50 I checked the RS232 for continuity and it is OK. I started doing the test in the KAT100 Manual. When I set the antenna to 2 and turn off the K2 and then back on I noted the antenna back on ANT 1 I also noticed when first powered up the lights on the KAT100 are bright but then dim a bit. Maybe this will point towards the problem? I suspect I have a bad solder point somewhere in the KAT100.
