[Re: [NLRS] Resend : BPL]

[Clare Jarvis]

I agree with you Jerry, that power lines are transmission lines
for power, not information.  The will radiate unacceptably.
I am not defending BPL but I think that we shouldn't be
viewed as nay-sayarers but let the company run its experiment
and find out that it isn't going to produced acceptable noise
figures.  After enough companies run the experiments, then
they will figure it out that BPL is unacceptable for two
reasons.  1.. It interfers with licensed radio services
and it is subject to interference by licensed radio services.
They just won't want to hear customer complaints about
dropped connects every time a ham or cber keys down.
