7.2kv/240 volt system here. 20+ years of 120hz issues on and off at this QTH. Current source details here; https://qsl.net/af4o/Powerline%20RFI%20QSL.net%20Webpage/Fall%202021%20Source%202.html My cu
Hi Mike, Thanks for the reply. The source *IS* still active but highly intermittent. It actually became intermittent last weekend. They came about 10:30am yesterday but I heard bursts from it shortly
I am in a, lets say less than affluent, rural county in TN where one would think maybe AM broadcast is still viable. When the lineman the other day fixed one of my power line arc's, he stated "Your t
Correction; I am in the Clear!! Since Friday I have not heard anything confirmed 120hz related except some brief bursts Friday night which I now think were unrelated (long explanation). It had me foo

Maybe it wont be as bad as CA or CO where old sodium, mercury vapor, etc systems are still used. Seems many (most?) of the new systems are LED. I know their SMPS can spew also but perhaps maybe not n
Awesome. Very cool. Thanks for sharing. What model camera did you use? Been thinking of getting a new one. Do you know the phase voltage? 73 Chuck W4NBO On 12/20/21 1:36 PM, Don Kirk wrote: Utter dis
Very Good point. I wonder how much money was saved, not to mention safety (disabled using powered medical equipment for instance) by Don, you, me, and many others finding these things prior to outage
Thumbs up Don. Waiting for the next episode! That's just wrong for a small SMPS to propagate that far. Thanks for sharing! Chuck W4NBO On 1/4/22 10:07 PM, Don Kirk wrote: I work hard keeping my noise
I abandoned my wired network in favor of wifi per Jims suggestion. Fought shielded cables, toroids, different equipment etc for years on and off trying to mitigate the hf rfi. Still hear some very we
Shopping to replace my 25 yr old 2.5 ton 80kBtuh gas fired all in one package heat/air unit for my small 1250sq ft brick house. I sure hate to give it up. RFI free and never called anyone to fix it.
I have been pondering on whether to do this or just wait until it died on its own. I triangulated some RFI to a light over my next door neighbors shed about 100' from my antennas. Thinks its high pre
Appreciate that Dave. The shed is in a state of deterioration and do not think its used for anything. Shingles are rotten on it. Thats the reason I thought I would just ask them if i could unscrew th
Thanks Ken. This one has no light at all, just cycling rf noise. The fixture looks like the old style street light. I am guessing it has a screw in photo cell, so I may could unscrew the bulb and pho
Thanks Ed. Thats a good idea. If they care so little as to not turn it off, then I will just filter it out until it dies. The shed is in sad shape. Rotten shingles, etc. Could very well be a fire haz
I don't know of any neighbors that know them. I wrote a letter and will mail it tomorrow. Explained since I did not know when they were home and did not want to interrupt anything, thought I would wr

I got my new HVAC unit this evening. York 14 seer gas/ac package unit, yep after rethinking decided to go with gas again for several reasons. / / /In heat mode I cannot find any RFI from it./**Its 21
Hi Jim, Yep. With this unit, I was mainly concerned with the ECM Motor (used for the blower) which, from what I have read of specs on various manufacturers websites, is pretty much mainstream current
