I know the proposed BPL system uses frequencies from 2-80 MHz
and I belive it uses spread spectrum.

At the moment, it does not appear that they are using the entire
2-80 MHz, at least in Emmaus, PA ... but they could expand.

Does it have to use
every possible freq in that range or could it skip the ham
bands if we kick up enough fuss?

There is still the issue of intermod, harmonics, etc. And, simply
avoiding the ham bands won't protect the other users of HF.
NTIA and its USG "clients" will, hopefully, be one of our strongest
allies ... we should not take a "protect us and the heck with everyone
else" approach ... to do so would dillute our potential support.

It seems pretty clear to me that it will happen - 150,000 hams
are outnumbered by more than 100:1 by those who want broadband
delivered to the doorstep.

Not only do I think it will happen, but I also expect the RFI
levels to be "adjusted" so as to allow more pollution - hey,
it works for greenhouse gas and power plants and......

Clearly, BPL proponents want to be allowed to use higher levels.
That, of course, will only make the interference that much worse
than it already is (which is MORE than bad enough - horrible, in
fact).
