This recent discussion kind of hit home today. My shack is self contained and about 25 ft. from the back of my house. About 3 months ago the power company hired a tree trimming company to clear branches from near the power line service in the area near where we live. They have almost finished the job in a 5 mile radius when I noticed that a lot of the noise I had been hearing disappeared.
About 3 weeks ago a real loud buzz saw signal appeared on 3.730 or so and extended up to near 3.775. It was terrible and kind of made me mad. So finally today I had the time and inclination to see if it originated in the house. I used a small Sony SW receiver and put the antenna all the way down and started sniffing. The noise was almost non-existent at the service entrance so I kept looking. Finally I found that my Zoom ADSL modem seemed to be the point of origin. When I unplugged it, the noise went away completely. Thinking it was the wart, I put another on it and the noise came back somewhat. I had another modem sitting here so I changed and now the band is clear again. I noticed on the label that the wart sticker said it is Rohs compliant. So my guess both it and the modem might have grown tin whiskers. I just wonder if I have avoided a potential house fire in addition to clearing a real buzz saw. Boy do I hate progress.
