What happens to a BPL signal when a 100 or 500 watt mobile is under the
line?

The 10 house area may be a good place to hold a mobile antenna shoot out.

If you can't hear anything, send in complaints about the noise. If the home
owners can't see anything on their computers, I am sure they will complain.

Normally power line noise we hear is power wasted to ground from arcing and
that costs the power companies money because it is not metered power and
therefore not billable. Report areas where there is high noise. You will
be surprised--sometimes it goes away totally!

Some of the trial areas have about 10 homes in them. The industry still

says,
with a straight face, we had no reports of interference, so this

"proves" we
won't interfere.

Something occurred to me - If the BPL test areas are using only
2-22 mHz, they they WILL avoid critical interference complaints
from Low Band VHF Public Safety users and others, and will be able to
say "We had no complaints from (same)", while conveniently overlooking
the fact that they couldn't have had complaints because they didn't
generate any interference to those operations!

(I mentioned this to contacts in PubSafety. I also suggested spectrum
analysis to determine what spectrum is actually being used.)

So we are very careful to make certain that the interference we
find actually is BPL. And since they are only using a portion of the
spectrum that would be used under full implementation of BPL, they
will be able to say, about users of spectrum which they aren't testing
within, "We got no complaints from them" when in fact the interference
will occurr only when BPL is fully implemented!
And of course there will be no such complaints inasmuch as no
interference was generated! So those users get blindsided, having
assumed there would be no interference from BPL.
It's amazing how well they're playing both ends against the middle.
One REALLY has to think about all this to stay on top of this mess.

The longer one looks at BPL as presented the worse it smells.
