[SkyHub] Power Line Noise

[Christopher Campbell]

 Harold,Most sincerely, Thank You for the offer! I have things I must finish before I bite this off, but one of thesedays ( within the next two months ) I will be coming to you to borrow it. This thing has bothered me forover three years, unceasingly riding at S7 to S9; the S9 level is calibrated at 50 microvolts. It occasionallypops up to 20 decibels over S9. I cut off all 120 / 240 volt power to the duplex where I live just to be certainthat it wasn't something there. I drove the neighborhood with my mobile on the 20 meter band and the noise follows the power lines, but couldn't discern any rise or fall in strength that would point me to thesource. The noise is at its most horrendous strength at 40 and 20 meters although still bad enoughon 80 meters that I can't really hear a net control station in Colorado Springs. It drops off rapidly rightat 15 megahertz.                                         Christopher C. Campbell, N0NDF                                         707-330-5298

 There was a discussion of power line noise on tonight's net. My adventures
in power line noise are at https://w6iwi.org/PowerLineNoise/ .

In particular, see the ARRL power line noise mitigtation form. Filling out
this form got Xcel out here, and they solved the problem in my area.

Also, if anyone would like to borrow it, I have an MFJ power line noise
receiver that can be used to hunt down the noise source.

Good luck!
