particularly because it never happens when it's raining. We found one such on a pole on the edge of my property that was arcing between a bracket (mounting a lightning arrestor) and a lag screw that

... Actually from my experience this is probably good news. I've been told by K3RFI (who does RFI investigations for a local power company, and has been a great help), and confirmed through reading,

Wow! I'm surprised and gratified at the number of responses to my RFI problem. Thanks to everyone. Let me answer some questions and discuss some issues raised in the responses: I have done some readi
This is typical and for a number of reasons, IMHO. When I had all my noise, my FT-847 would show S7 or even S9 noise levels on 6m, 2m, etc. However, on HF, my FT-1000D wouldn't - unless I turned my n

In the case of the noise I mentioned yesterday, it was inaudible on 40m and below, barely audible on 20, definitely there on 15, and quite annoying on 10 anytime I pointed my antennas toward Japan. I

And you might be able to hear it at your station if your antenna where a different polarization or running 90 degrees from where it lays now or in some other configuration. You hafta take into consi
You need a small UHF beam and AM mode receiver. Operating at (say) 440 Mhz, you can use a beam to idetify actual sources. I used aircraft band AM to get close to a source, and zeroed in on it with 1.

The source of the RFI need not be in your immediate neighborhood. I had the local power company out here twice to track down an s9+ noise that was across my entire HF received spectrum. The first tim

Sure, and I betcha that arc was audible throughout the HF spectrum and beyond. I believe the notion that arcing heard only at higher HF frequencies is likely to be quite close still holds, at least a

Thanks again to one and all for this excellent discussion. Let me continue to add to my description of the noise(s). Right now the noise is going full bore on 6M. It peaks S9 with my beam pointed S-S

I've got a noise problem, and although I perhaps haven't done enough legwork yet to be writing responsibly to this reflector, I thought I'd give a shot with a description to see if anyone's run acros
John, Sounds to me like you have some bad arrestors or insulators on a power pole somewhere near you. I have had similar problems to what you describe. One time, I could hear the hum all the way into
Hi John, Interesting that you should bring this up......I have a similar problem........It affects only 6, 10 and perhaps 15 meters (I know I dont have a problem on 20).............I have traced the
