Re: [RFI] Rain induced static (score: 1): Author: Pete Smith <n4zr@contesting.com>; Date: Tue, 04 Dec 2007 17:29:20 -0500; Let me second Don's advice; I have a noisy pole about 400 meters from my antennas that is S9+ when dry and silent when it rains. In fact, that is one of the defining characteristics of low/medium vol; /archives//html/RFI/2007-12/msg00010.html (9,060 bytes)
203. [RFI] powerline noise that seems to peak in frequency (score: 1): Author: Pete Smith <n4zr@contesting.com>; Date: Sat, 08 Dec 2007 17:23:10 -0500; Today, listening on 10m, I noticed that whenever I tuned into the 28400-475 range, there would be a marked increase in what sounded very much like ordinary powerline noise.

Real "powerline" noise is broadband, but that isn't necessarily to say that noise with significant 60/120 Hz components can't be narrow-band.
