AND do you have the radio to ground. Separate from house ground. IE uncouple the house ground from the plug (no ground to house.) I have a Rebar thumped down into DAMP earth outside the house with a cable running to my radio room which I hook up to Radio. For Safety I have a Knife switch isolating the ground AND separately the External Arial as protection in the event of lightning. I shut down everything from a master switch and drop the knife switch as a habit.

So

1. Good external Arial check.
2. External ground check.
3. Check the nica on the inside to of the can.
3 follow Terry,s suggestion above to de-tune or re-tune the rf.

Wow. Great Hakka.
