I was able to borrow a portable shortwave radio today, and we clearly
determined the noise is from about a block over. I will build a loop for the
radio tonight and take another whack at it tomorrow.
Anyone have any suggestions for approaching a neighbor you have not met (if
it's in a house) in this era of social distancing?
Thanks and 73,

What type of internet service do you have, DSL? Does your modem have battery
backup? I chased my tail with my cable modem, it has battery backup since I
also have voip from them as well....switching off breakers makes little
difference with battery backup devices....
