Re: another major BPL deployment

[nobody@xxxxxxxxxxxx (Dave Houston)]

Maybe you should actually read what's on the ARRL website. I'll quote from
http://www.arrl.org/tis/info/HTML/plc/

"Radio amateurs are not opposed to broadband services. On the contrary, they
tend to be early adopters of new technology. However, there are ways to
deliver broadband that do not pollute the radio spectrum as Broadband over
Power Line (BPL) does. These include fiber-to-the-home, cable, DSL, and
wireless broadband. The ARRL--The National Association for Amateur Radio--
is supportive of broadband access for all Americans; however, it opposes BPL
as a way to achieve this goal because of its high potential for causing
interference to radiocommunication."

Sure seems like it says they oppose all BPL.

In the above cited case, the FCC seems to have determined that the ARRL
claims were baseless. Are there any cases where the FCC agreed with the
ARRL? I really don't want to waste my time on one-sided ARRL reports of
interference when the FCC appears to disagree in one such case they
investigated.
