The posting from Courtland - KA5S prompted me to look further into Power Line
based broadband communications. here is what I found at
http://www.powerlineworld.com/powerlineintro.html

"Soon after the first trials of Digital PowerLine in the UK, some unanticipated
problems arose. Certain radio frequencies were suddenly deluged with traffic,
making it impossible to transmit on those frequencies. BBC, amateur radio, and
the UKs emergency broadcasting service were affected. The apparent culprits
were standard light poles. Then it became clear that by pure chance British
light poles were the perfect size and shape to broadcast Digital PowerLine
signals. This situation posed problems not just because of the frequencies
involved but also because anyone could listen in on the traffic. Nor.Web is
addressing the problem by proposing to lease the frequencies involved from their
owners and offering amateur radio operators a new frequency. Negotiations on
this topic are currently taking place in London. The privacy issue has not been
fully addressed at this point, besides suggestions that all  sensitive
information should be encrypted."

Looks like we're in for a new round of RFI interference from our power
companies.
