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.

>> Yes, I did run the K3 off of a battery and pulled the main AC breaker. Didn?t make any difference. Thus my suspicion that the RFI is related to the 208 kW ERP TV station (and/or 63 kW EPR FM station) which are within 1.6 miles and in direct line of sight.
