Wouldn't it be possible to place a filter at your meter that would
shunt the BPL signal to ground for the whole neighborhood?

Probably not. But a couple of companies, including Motorola have BPL
systems that do NOT interfere with amateur radio services at all.
The problem seems to be getting regulatory agencies to mandate such
systems rather than the sloppy ones they seem to have been bribed to
permit.

Read the ARRL's story on Motorola LV: 'Less than two years after
announcing its Powerline LV Access BPL product, Motorola has decided
to suspend product development and to devote its resources to more
promising markets, industry sources say.' Full story at
http://www.arrl.org/news/stories/2007/04/25/102/?nc=1 .

That is a reduction in focus on Access BPL, and the form with the
widest impact, but that is only one form of the BPL scourge.

Dave, perhaps what you see in me as pessimism is more realism, and it
is born out of working in the telecommunications industry,
understanding the carriage market and the challenges in competetive
broadband delivery.

I have also measured BPL emission on the street, analysed measurements
by others and written / reviewed many reports on the impact of BPL
emissions. I have a good understanding of the impact, and the BS of
the 'it won't affect me' justication of apathy.

The transformation of ham radio to the province of six hour hams with
their shack on their belt impacts the sustainability of ham radio.
They do not have the knowledge and experience, the credibility to
challenge the threat.

The 'it won't affect me' approach and redneck solutions help to divert
attention from the BPL problem.

BPL might crash and burn of its own accord, and I frequently see
people calling out the failure of a small BPL deployment as evidence,
but in the last few hours I have reviewed a report on ambient noise
measurements in an area for planned BPL deployment in the coming
weeks, and the implementor is no small naive power company business
development unit. BPL remains a serious threat.

Oh, I'm not downplaying it as a threat. It's just one more symptom,
though of what has gone wrong in our world. It used to be that "money
talk's; bull**** walks" was the adage. Now it's "money bull****s and
everyone else is supposed to bow down and kiss its feet."
