What you are proposing is to shift the cost of correcting the
interference caused by this technology from those who will profit from
it to the victims of the interference.
Do you plan to invest your BPL profits into stock in the companys
that will manufacture the new radio equipment that your technology
will force us all to buy?

The claim that BPL will seriously and negatively impact amateur radio
is simply fear, uncertainty, and doubt (FUD) spread by the ARRL. That
organization needs to justify its existence, and the BPL issue is a
convenient way for it to show its activism. The ARRL has apparently
followed the path of other self-justifying organizations such as NOW
and the NAACP.

Unfortunately, the technically unsophisticated do not recognize the
difference between coherent and non-coherent noise, and this makes it
easy for the ARRL to spread its FUD. But the fact is that, if BPL
signals are heard at all, they are coherent (have a predictable phase
and amplitude) and therefore can be completely removed at the
receiver. This can be done in many ways, most of which amount to
nulling the BPL signals by introducing an identical signal which is
180 degrees out of phase with the original. As a matter of fact, most
current HF transceivers have what they call a "noise reduction" option
already built into them which uses the nulling method to accomplish
its goal. Therefore, many amateurs and SWLers already have the needed
equipment to deal with any BPL "interference." The ARRL reports have
conveniently omitted any mention of the coherency issue, and their
measurements are therefore flawed, because they don't reflect real
world situations.

So take the ARRL claims with a large grain of salt, and don't succumb
to the FUD they are spreading. Instead, do some reading on your own
by going to non-ARRL web pages such as http://www.uplc.utc.org, and
http://www.wave-report.com/tutorials/bpl.htm before accepting the ARRL
claims at face value.
