1. Topband: Finding powerline noise (score: 1): Author: ford@cmgate.com (Ford Peterson); Date: Mon, 9 Dec 2002 23:21:08 -0600; Here I go, coloring outside the lines again... It occurs to me that hardware and insulator maintenance are the only real fixes to power line noise. Finding the source of the noise is a real problem,; /archives//html/Topband/2002-12/msg00140.html (7,927 bytes)
2. Topband: Finding powerline noise (score: 1): Author: n4zr@contesting.com (Pete Smith); Date: Tue, 10 Dec 2002 08:02:41 -0500; Based on my experience over the last several years, I think this is mistaken. My worst noise sources are the old-style insulators on slack spans, stretches of high-voltage feeder that hang loosely (h; /archives//html/Topband/2002-12/msg00151.html (9,538 bytes)
3. Topband: Finding powerline noise (score: 1): Author: n5ia@zia-connection.com (Milt Jensen, N5IA); Date: Tue, 10 Dec 2002 10:30:24 -0500; Ford, If I might. In my 30+ years of distribution power line experience I have seen/found very few RF noise problems cuased by "leaking" primary voltage conductors.

4. Topband: Finding powerline noise (score: 1): Author: df2py@t-online.de (DF2PY); Date: Tue, 10 Dec 2002 19:27:57 +0100; hi reflectees ! Ford - N0FP- raised the idea of "probing" a power- pole for identifying bad insulators. The approach thru a coupling that relies on the magnetic coupling into a pick-up-loop will not; /archives//html/Topband/2002-12/msg00161.html (7,907 bytes)

Topband: Finding powerline noise (score: 1): Author: tberry1@triad.rr.com (Tom Berry); Date: Fri, 20 Dec 2002 14:54:30 -0500; Milt, I'm not sure I understand all I know about finding noise from the power lines. ... I have a very big problem here and wanted to ask a question. Are you saying I should look at my internal house; /archives//html/Topband/2002-12/msg00164.html (7,746 bytes)
6. Topband: Finding powerline noise (score: 1): Author: k7mw@cmc.net (Rick Dettinger); Date: Tue, 10 Dec 2002 15:13:09 -0500; Ford Any leakage current will return to the substation on the neutral conductor, just like the normal load current. The pole ground is more of a safety feature then a current return as the ground wil; /archives//html/Topband/2002-12/msg00166.html (7,277 bytes)

I did not want to write a treatise on the subject. To answer your question: NO. I was stating that, in my area of the country with the types of di; /archives//html/Topband/2002-12/msg00174.html (10,698 bytes)
