Just an update from when I started this topic.
I kept a log of when and where I heard the noise. One day when it was
strong, I drove around with my handheld at 135mhz am, in the direction my
beam told me the noise was. I found a power pole with 3 transformers on it,
in an industrial area of St. Cloud, 1 mile from my house. When I drove under
the pole, it was clearly audiable at 135mhz. I repeated this routine a
couple times. When I heard the noise loud on 6m at home, it was noisy at the
pole. When 6m was quiet at home, it was quiet under the pole. After
searching there website, I called Xcel customer support and asked what it
would take to file a report or whatever I needed to to. They took my report
right there on the phone, and the next day I got a call from one of the
local line men. We discused my findings and he said he would go check out
the area. Couple days later he called me back and said there was a bad
lightning arrestor on the pole I pointed him to, and he replaced it and
wanted me to check for any more noise.
I monitored 6m again, and found a new sounding noise, with a different beam
heading. After shuting down the circuit breakers in the house one at a time,
turned out my camper trailer, which is pluged into the garage to keep the
battery charged, has a very noisy power convertor. I turned off the
convertor and the new noise was gone.
Back to the radio again and started tuning around. 6m was quite but I had
some bad noise on 160m. That ended up being the APC UPS sitting under my
bench.
I'm on the NW side of St. Cloud, if I sweep my 6m beam a full rotation, the
noise floor is a little higher from about SE-S but nothing that moves the S
meter like it used to. I don't expect I'll ever find all the noise sources
in town, and didn't plan on trying. I'm happy for now. Xcel was very
helpfull and understanding.
