Hi Guys, I had a similar situation at my QTH in SE Lower Michigan with Spectrum. Their tech came inside to install a new telephone modem and found high SWR on their line to/from/within my house. The tech replaced all the crimp-on coax connectors and the problem cleared up. He told me the shield connection of the connector was the problem and he just replaced them all rather than take the time to find the bad one(s). He didn’t replace any of the coax, only the connectors. Michigan is the second worst lightning capitol of North America due to the high copper content in the ground/earth. 73

They showed up claiming I was taking out a large area (10 block square) on their spectrum analyzer. Mine showed up on 16 Mhz up when I operated any band on any of 4 antennas. I was using my K3 KPA 500 combo. I worked with them over 3 months giving them ideas and suggestions but I was adamant it was there problem not mine. By the way I wasn't getting into my TV or internet nor any of my neighbors. They checked their lines for leakage, and even ran new burried cable to me but it still didn't fix it. I suggested they check their ground wire going up their pole in an easement behind my house. Bingo!!! They had a ground rod at the foot of the pole and a 30 foot wire running up the pole but they never had connected it. I have since learned from a local ham friend who was an inspector involved in several court cases with Xfinity over on our east coast here in Florida, that this is common procedure for them. We are in the lightning capital of North America and they, according to him, were trying to avoid lightning strikes to their equipment. Lightning was hitting the power company equipment instead.If you would like to contact the man who won in court in these cases contact me at my call at arrl.net and I will give you his contact info.Don, W4CBS Sent from my Sprint Samsung Galaxy S20+ 5G. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
