[DX] ARRL BPL Video

I must confess that I am puzzled by the anger by some hams over BPL. The only 
data I have been able to dig out on the web, regarding the US, is a summary 
of W1RFI's data-taking trip. IF I understand it correctly--and I trust I will 
be corrected with fact if I am wrong-- W1RFI made measurements well within the 
near field of the emissions; underneath the lines; generally parallel to the 
lines;and so on. Is there any data which supports those damning interpretations 
from an actual ham residence? How many of us live --under-- in- the- air , 
residential power lines? Is there any record of complaint from a ham in the 
towns visited by W1RFI regarding RFI from BPL? Has any ham volunteered to assist 
the ARRL in gathering data from a residence in which the BPL is active, and the 
ham experiences major QRM? If not, then why not?

Incidentally, I have tried 8 times to download the video from the ARRL site, 
without success. This is with a T1 line.

I have major concerns that if we present 'evidence' which is biased in some 
way, then we, as a licensed service, will have the argument thrown back at us. 
We are already seeing how the FCC perceives our use of the  60M band as purely 
 an emergency  service role (which is a valuable role indeed), rather than a 
hobbyist or technical advancement one. If that is how the FCC sees the future 
of the amateur service, then why is the issue of BPL so compelling? If there 
is an emergency, then BPL would be down--and the QRM would be gone (if it 
really was a problem to start).

I would be very interested in studies that show that BPL introduces S9+ QRM 
30 miles away, or skips to the west coast for example. Is there any US data on 
that? 

Please do not respond in anger to my comments. I am merely posing a critique 
of the data so discussed. I also feel that if there is more data which bears 
greater applicability, then I, and others, might be so pursuaded.
