[Elecraft] Mysterious K3 Symptoms - RFI?

[Bayard Coolidge, N1HO]

 Unfortunately, with the high population density in my immediate neighborhood, especially with 150+ condominium apartments right next door, I have a difficult time getting a reliable wi-fi connection to my home network. I'm about 900 feet (240m) west of the Intracoastal Waterway, and have 2, 3, 5 and 7 floor condo buildings between me and the ICW. To the north, west and south, I have single-family homes. Along the south (i.e., rear) side of our house lot, I have 7.5kV 3-phase power lines overhead, which feed the homes on the block south of us; we're fed by underground feeders installed 2 years ago. To make matters more interesting, we have a steel "ridgepole" running the length of the house, atop the actual conventional wooden ridgepole, which supports the curved concrete tiles at the top of the roof. I suspect that noise is coupling from it onto my TWP Ethernet line as well. I used the simple/cheap MFJ clamp-on chokes at both the shack end and the end in the den where it's plugged into the ISP's modem/router. Basically, I'm doing the best I can with what I've got.

 I recommend replacing Ethernet cables with wifi when possible, both for noise and rfi problems, as well as reducing the chance of lightning damage.
