[GCARC] Experience negotiating with RFI Owners

[Christopher Wawak]

I'm faced with S7-S9 noise across 40m-15m at 200khz intervals. I'm looking
for assistance resolving this RFI I suspect is coming from a neighbor's
solar installation. The owners are elderly, and I'm not sure they'll
understand and be able to remedy the situation. HF is next to unusable.


Some questions:

0. So far, do I seem on the right path?

1. What tactics have worked in the past with getting owners to respond?

2. Right now I have an AH-4 with a wire antenna. If I switched to, say, a
fan dipole or a beam antenna would i be able to reject the solar panel
noise? If my antenna were higher up, would that help?

3. Am I doomed to not have workable HF at home?

RFI Location

Appears to be coming from solar panels on a house behind my own, about 275’
away. I traced this with a loop antenna and a cheap AM radio following to
where the noise seemed loudest.

Characteristics

Heavy S7+ “hash” noise every ~200 khz, starting around 40m and going all
the way up through 15m.


Generally starts an hour or two after sunrise, and shuts down before sunset.
