If what you says is true, Ed, then our only real hope is that
Motorola system with its hard analog notch filters beomces
the widely adopted standard. BTW, have there been any
actual ARRL attended demonstrations of the Motorola system
which show that it really is effective? With all the non-linearities
that could be present on a power line system, my big fear has
been that IMD products will tend fill-in regions which are
hard notched with analog filters, thus limiting the ultimate
rejection capability. Is there any data on this?

Mike,
On the BPLandHamRadio yahoogroup Ed Hare has said that Motorola came to
them first looking for information. (I was also approached last year
for BPL info by my Motorola sales contacts as well!) So I think they've
been open with the ARRL from the start. Don't know or recall if they've
attended any demos yet. Mr. Hare would be the one to address the data
question, but I don't think he's had time to be on this list in a while
now due to BPL.
The Motorola systems is not on the MV power lines feeding each
neighborhood; it's only on the house wiring just like HomePlug. It's
wireless from the Substns to each pad, with an option for a fully
wireless system if there's any interference issues, like a ham or SWL.
The problem with this is that utility mgmt doesn't consider the
"wireless" Motorola system to be BPL. And every time they've heard the
words "wireless" and Motorola in the same sentence it has always
translated to "Expensive" especially when looking at doing this over a
large service area. That's why most utilities haven't already installed
something like this on a large scale.
Of course my comments don't apply to every utility. Some like Cinergy &
Southern Co. are looking to get into the internet market first (among
others) and do the energy stuff on the side. But most smaller utilities
seem to be just the opposite. The trick will be if the internet market
fails, will there be any BPL mfrs left in the market to do the
energy-only stuff for the other utilities? It will be interesting to
see how it is finally done in the end.
