Default MA5B background noise

How did you manage it? Who did you report it to?


The power pole ground wire didn't appear to be
broken, just radiating like crazy. I managed
it by transmitting on the vertical and receiving
on the dipole. In the process of A/B comparisons,
I discovered that the vertical was never better
than the dipole and usually worse. The EZNEC
comparisons are on my web page at:

To be fair, since receiving was limited to East/
West QSOs, the Extended Zepp beat the socks off
the vertical.


On 40m, most run horiz. Horiz-to-horiz is always going to beat
horiz-to-vert.

Knowing you and your strong personality (at least from the news group) I
thought you might had been able to secure a fix from the power
companies' noise emissions. Was just wondering, and probably wouldn't
have helped with my problem anyway ...

Right now, I have an issue with a noise source I cannot even pinpoint
and is very broadband (and no, it is not BPL -- already ruled that out,
lol.) Noise is for blocks and remains fairly constant in strength.
This would lead me to think it was powerlines; however, the powerlines
are all underground! Which leads me to believe some noise IS on the
powerlines and the radiation is coming from the wiring in each
individual home/business. However, a scope, properly isolated and
hooked to my wiring doesn't give me a picture I can correlate to ... :-(

If it ain't one thing, it is another ... keeps life interesting, I guess.
