Bonneville Power Administration has been in the news lately in the Puget
Sound area of Washington State. People have been complaining of new
continuous buzzing from their high tension transmission lines. It seems
they
use to operate them at 253,000 volts, but now have increased the voltage
to
500,000 volts, which causes the buzzing.

I am wondering if that kind of increase would show up as a loud noise in
the frequency bands between 2 Mhz and 4 Mhz ? It wipes out everything -
period, unless the signal is strong enough to break through. It exists
also
at higher frequencies to a lesser extent.

The sound is not staticky like atmospheric noise or normal power line
noise,
but more like what you would get if you sat the set on top of an operating
television set.

Sounds more like experimentation with BPL...

As for the voltage increase, I'm not going to say it didn't happen, but it's
highly unlikely that it did. The reason I say this is, they would have had
to change out major transformers downstream (not to mention at the source),
which would have resulted in a lot of down time (they would have had to
change hundreds of substations all at once).
