Update; After logging weather conditions related to the noise. The first few hours of a rain, I can still hear it although its not as constant. After that and a good rain it stops. Then it takes >36

Its sounds like 120hz to me (power lines ). I recorded a segment and run it through Audacity, expanded it out, and can see the spikes at about that rate. No street views on google for your QTH but fr

I see where you stated the util's are underground, my bad. At least with the util's underground it will reduce the chance you are chasing the wrong noise. Keep us informed, be interesting to know wha

It is a shame RFI does not get more attention legally. I wonder if a situation that inhibited golf to the extent RFI inhibits ham radio were to occur, how long would it be before laws were changed? A
