Yeah, that sneaky Jim--always working a ploy.

On BPL? Well there are a lot of test blocks where that is being
technically tested, evaluated and data is being recorded. I don't think
one needs futurist papers, Sylvia Browne, or some hams opinion--technical
data will make it a reality or not... that final data is not available
yet... I don't think a bunch of aging hams are going to block a
multi-billion dollar a year industry, if it is technically feasibly, I
know some of them think so, but rational men viewing them only grin behind
their backs--but, as long as they only pay attention to their "net
buddy's" they will not have to suffer the embarrassment of coping with
reality...

A bunch of aging hams who are federally licensed trumps Part 15 users
each and every time. Some of those supposed rational, grinning men have
had to yank their BPL systems down because of interference.

Or, perhaps there is something of deep meaning and paramount importance
which I am failing to see here?

"Since you purport to have a ee degree, you might explain how some
signals held below 300 KHz could possibly serve a number of users (say
in a neighborhood) at 3 megabaud (or higher) rates?"

There you go.
