"Perhaps check and see if the drive from the TS-590s is varying, or if the gain of the KPA500 is changing. What does the output meter on the 590 say when this happens?"
TS-590S power meter does not change nor does TS-590S indicated SWR. However, I did find that TS-590S ALC reading is cycling. (There is no ALC connection between KPA500 and TS-590S). I need to look more closely at what the TS-590S is doing.
