Yes, and if they continue not to generate signals on low VHF, they
will continue not get any complaints.


But is is almost certain they they will claim success for their
"tests" in that "We got no complaints from low VHF users" when they
generated no such interference during testing-but are sure to when BPL
is widely implemented. That seems to make it very much necessary for
someone to document the parameters of what they DO generate so that
accurate information is available to challenge those later claims with
the facts when they make *inaccurate* reports of their of their
"successful" tests to FCC. It must be shown that the tests were
not properly done so as to actually test the system that will be
put into service.

That's a pretty substantial project-documenting the interference
generated at each -or at least certain critical- BPL test sites where
this could be the result. It then requires knowledge of local
conditions such as knowledge of what spectrum that is used locally by
which users.

No wonder the BPL people are confident of a win. None of this is
accidental.


If they would reduce their emissions on the
ham bands to about 60 dB less than FCC, amateur radio wouldn't get a
significant amount of interference and ARRL could move on to new
challenges.


It's almost a certainty that the only way they will do that is if
they're challenged with collected data that causes FCC to require it.

If they were to do what it would take to reduce their emissions by 60
dB, the system flat out won't work ... it only works passably as it is,
which is why they want to up the power. (A former user in the PPL
trial area told me - in front of the reporter - that when he had the
system working (before his service died and PPL couldn't/wouldn't fix
it) he was getting "Maybe 4x dial-up speeds ..." He clearly wasn't
impressed. Let's hope that there's a lot of that going around. )

Far be it from me to suggest deliberate QRM to BPL, but I think it would
be nice if everyone could run full legal in areas with BPL trials. Or at
least as much QRO as they could muster. Maybe if we know an area where
it's happening we could all descend with linears and set up a multi-multi
QRO contest station. Perhaps with 1500w signals on three or four bands we
could get their speed down to 14.4k?
