Not necessarily -- I would choke all wires attached to the main unit.
It's the most likely culprit.

Frank. . . about a year or so ago I had a nasty RFI problem on TB

November through March (prime TB season) and was about S7 on the

Rick,
When I mentioned using an AM radio with a 3 or 4 element yagi when within
0.25 miles of the source I should have said that’s up on VHF (like 136 or
146 MHz, etc.) if it’s really power line noise (arcing hardware).

Hi Frank,
Thanks for mentioning my portable flag, and that's the way to go to get
close to the area of the suspect pole but I didn't want to toot my own
horn. It really is an easy antenna to build and its build is very
forgiving, and glad to hear it exceeded your expectations.
I do recommend usi
Kenny,
It’s not easy and in fact I haven’t done it for anything lower than 40m. It
would be very interesting to compare something at the water’s edge to what I
have now. The shoreline runs SW-NE - I think about 215-35. The question is

The coverage is almost 180 degrees in the direction of the salt water

I trip a GFI breaker sometimes on 160m, usually in a contest 1500W.
Never had a problem when GFI outlets were the norm, but I had some electrical
work done in an added
room and the new code calls for a GFI breaker.
Has anyone had a similar experience and located an RFI resistant GFI breaker?

What brand of thermostat is it? A smart thermostat?
Shielding likely won't help.
How far is the antenna away from the wiring?

Thanks for the praise! I wish I would have the same RX capabilities as TX, but
my limited sized rock wont allow for it. Right now I have two pennants, one in
