Nicklas Johnson 🏳️🌈I have now determined with high certainty which utility pole is causing the #RFI problem in my neighborhood. It's very near my QTH.
To differentiate it, I stood directly in front of it where turning to the left would point me at the other suspect pole but put the pole I was facing in the 45° null in the antenna pattern.
When I turned to face the other suspect pole, the sound went away as the first pole fell into the null in the pattern.
Then I walked around to the other block and pointed around from the other direction just to make sure it wasn't some other utility pole in the same direction but further away.
I'm about 99.44% certain I've found the culprit. Now I just need to get PG&E to do something about it.
