I have/had the same problem with the KXPA100/KAT100 except it would go into fault. I checked everything I could and couldn't find any bad connections. My antenna is a cobra folded dipole and the twin lead is very close to my operating position and there is a balun at the twin lead. I added more coax between the balun and entry point and put a couple of snap on torroids on the coax and the problem has gone.
