[Elecraft] KAT 500 SWR FAULTS [INTERMITTENT]

[dave ingebright]

Jim, Thanks for your query. I'm tuning at less than 10W, KPA amp always in STBY. Sometimes the tuner finds a better match at a little more power (25-75 Watts); someone else mentioned that, too.
But again, yesterday, it found the solution (Multiband ladder-fed G5RV at 40') 14Mhz, and everything was fine during the first part of the FT8 QSO, and then the tuner went to a high SWR fault for no apparent reason.
I reset it, and it was fine for the rest of the operating session. It doesn't matter what band or what power. Remember, I have two of these doing the same thing. 
I still bet there are a couple of little reed relays with pitted contacts in the auto tuner. I am sure a lot of us have wondered how they get away with using those in a ~500W high-voltage environment. I will call the tech line, but wondered if any of you on this reflector have had this problem
