Yes, I do have three neighbors: two are about 550 ft away and one is 700 ft away. I have not asked them yet to pull their breakers. I thought the distance was far enough to eliminate RFI from household appliances, plasma TVs, etc. Also, the RFI is 24x7 so if it were caused by my neighbors’ plasma TVs, there shouldn’t be any RFI at, say, 3AM in the morning. There are no electric fences in our area. I do have a UPS. I eliminated that as the source also.
