[RFI] This'd help in some areas

That makes sense, Jim. We could then correlate low-band usage with BPL pilot
locations.  If there are matches, then we know where to focus our efforts.
If there are no matches, this fact would substantiate an allegation that the
BPL industry is gaming their pilots by choosing locations where interference
is unlikely, as is implied by at least one statement in the ARRL BPL web
site.

Doing an Ed Hare style video of a state highway patrolman sitting in his
cruiser trying to copy a dispatch thru BPL hash on his low-band VHF radio
would be very valueable IMO. It is much harder to dismiss the relavance of
mission critical public safety communications than those of a hobbyist. Heck
you could even do an control test outside the BPL area like Ed did to
demonstrate the degree of the degradation caused by the BPL system. This is
your clearly received emergency  dispatch, this is your not so clearly
received emergency dispatch on BPL - any questions?

I recently reviewed technical proposals for voice and data interoperability
systems for DOJ.  While there are a lot of legacy systems out there, many
jurisdictions have long switched over to either high-band repeat, or 800 MHz
trunking solutions. In some areas of the country, lowband is still used at
county level, and for linking with fire and ambulance services.

The point of this is...in many of the BPL trials, lowband may not be used
any longer.  At best, it's questionable.  It'd be good to know how many
states and counties still use lowband...and map the threat from there.
