Re: [Swprograms] OT: FCC BPL Meeting

["Richard Cuff" <richard@xxxxxxxxxxx>]

Had the chance to hear the Canadian saga of BPL on Sunday.  One of the ODXA
guys was able to obtain the architecture of the Sault St. Marie test loop
that was run earlier this year.

One of the interesting elements that came out of the testing up in Sault was
that the point source distance-squared model of radation decay is
technically inappropriate since the radiator is a wire, not a point.  As a
result, the radiation decayed on a linear distance basis, not a
least-squared basis, in the vicinity of the wire.

We also saw pictures of what BPL injection / removal connections looked
like, so it's a bit easier to spot BPL installations from the ground.

Joe -- you should get together with the ODXA's Bob Hawkins and compare
notes...

homeland.  The wine was great, the women are beautiful, and the cars really
go fast.  I do not know whether this has been posted anywhere in the SWL
community but it looks like the rules for BPL in the USA will be coming in
October.  Here is the ARRL's take on the issue from last Friday's
Newsletter:

> "Given the number of amateur stations and the fact that they almost
