Spurious Noise

I had a home a coupla hundred feet away from hi tension towers and it was a
nightmare plus.

I was not a ham when we moved in but I noticed lines across the TV video on
the lower channels all the time
and buzz in the TV audio. Annoying but not unusual in the days of rooftop TV
antennas.

It got and very severe when the insulators got damp. In fact at times during
the night one could see a blue arc discharge across the insulators.

When I got my ham ticket, I found S9+10 dB of noise was typical on the 160,
80, 40m bands (unusable for the most part)

Less noise up the spectrum but awful at times. Later when a got a small
triband beam, I would rotate the antenna 90 degrees away from the power
lines to reduce the noise and hope some of my signal got to Europe -- hi hi.

The power company would wash down the lines on occasion when I squawked, but
the noise would soon return.

When we moved to a new noise free (underground utilities) location, couldn't
believe the difference.

Take a portable SWL receiver and check the noise at various frequencies and
areas of the location.

But the noise could be in a "quiet period' i.e., clean and dry insulators.

But a Caveat -- your noise may vary -- others reported no problem.

For me I will never again move in anywhere near these spectrum blasters.
