David,

Looks like I'm going to have to research some nice linear as well as a
decent HF station. I had been looking at a vertical to avoid all of the
horizontal lines in the neighborhood, but, on second thought ... 1500 watts
horizontally polarized, 50 feet from the power lines might prove interesting

Money talks, public service walks- BPL is a certainty.

The "null it out- anyone can do it" argument is crap-
works well in theory, poorly in the field.
Even with excellent nulling, QRP and other weak signal work is finished.
Shortwave DXing is finished.

You have three choices-
Give up radio.
Move far enough into the country to avoid the polluted grid,
"Gorilla warfare-" Power lines that leak out, can also leak IN.
50 watts of broadband noise generator plugged into the nearest socket
would do. Note that I would never advocate anything illegal.....

Amazing, a scenario where an SWL would move into the city because of
less QRN.

I use the power line as an antenna for my baby SW RXs, when I carry them around
the house. In fact, using the power line provides better recpetion at 3.21 MHz
on my Grundig eTR7 than I get with my 40M inverted vee on my DX-392. LOL

Using the baby RXs on the power line, BPL might be fun.

Hmmm. I can't imagine any way Ham radio interference would do any good,
even if legal. Interference might not have effect it at all. Or it might
cause a slowdown the BPL user would attribute to internet congestion. If
the BPL user believes interference is casuing a problem with his gee-whiz
powerline internet access, he's gonna squak to the power company and maybe
the FCC. Face it, radio hobbyists are in no position for poor public
relations. There are more people who will be attracted to the bright, shiny
promise of BPL than there are radio hobbyists. Considering the numbers,
would it be unlikely for the FCC to redefine the interference limits?

I'd be curious to know how vunerable BPL is to interference. I have no
doubt the BPL people have run tests, and I'm a little surprised they're not
at the front of a webpage somewhere. Ham radio may not have alot of effect.
The power lines will only absorb a fraction of what's transmitted, and will
probably re-radiate most of that. I would think interference from devices
plugged directly into the lines would have the most effect. Like spikey old
universal motors and cheap switchmode power supplies.

Politically, it's far better if damaging interference comes from everyday
objects around the home. Like the vacuum cleaner, the microwave oven, the
kid's computer, etc.

And nothing will help as much as bringing new people into the radio hobby.

Jim:
Even BEFORE they start this BPL thing, the existing power lines emanate a
ton of interference anyways. It is almost impossible for me to listen to
anything HF around here because the lines around here are terrible. I can
only imagine how much worse it will get with adding the BPL stuff as well.
I am definitely a proponent of having the utilities switching (albeit
expensive) to buried electrical lines. Only exception might be where the
lines need to cross a river etc.
