I have a new approach to the  BPL interference discussion.

I'm quite certain no one on this list would engage in any activity by 
Amateur Radio Operators that would deliberately reduce the effectiveness 
of nearby (unlicensed) BPL activity. Perish the thought! That certainly 
is the farthest thing from MY mind.

However, it would be interesting to determine what the signal format of 
BPL is in a given area, so we can explore operating modes that most 
resemble that format --  within the Part 97 regulatory constraints, of 
course -- and use them extensively in those same areas. Who knows? Some 
digital format, such as Digtrx, may already fill the bill.

Why imitate the BPL format? Isn't it obvious? Since we are assured by 
the proponents of BPL that interference doesn't exist, because BPL 
doesn't radiate from power lines, we should use a very similar signal 
format.  It just makes sense -- if their signal doesn't leave the power 
line and interfere with area radio users, our signal shouldn't enter the 
powerlines and interfere with theirs. Right?

We should make a good-faith effort to test this new operating mode, 
perhaps with a nation-wide contest or two. We could call it "CQ-BPL," 
and grant a multiplier for every contact made to or from BPL-serviced 
areas of the country, and a big bonus if both operators are in areas 
with BPL activity. High-power stations should get extra points.

Doing anything this weekend?
