[RFI] New Interference at kk0sd

[Gary]

Thanks Gary, very good information. That is very similar to the loop I have been unable to hear the “noise” on. It worked great on my last adventire.

A sanity check is always a good thing and keep the suggestions coming.

I agree it really sounds like arcing associated with power lines, even though yours are underground. But I had that same sonic signature here, and the root cause was a big TIG welder that a neighbor had just plugged into 240. Not using it mind you, just idle. I told him something was generating noise in his garage and when he threw the breaker, that was it. He was a qualified electrical installer and right away he figured out there was probably a connection problem in the welder. I never heard exactly what he fixed, but that solved it.

No problem at all triangulating it with my trusty loop antenna. It was 20 over S9 on most bands...
