I'd like to pass along an American Radio Relay League (ARRL) article for those following the Broadband over Power Lines (BPL) situation.
Public BPL Database Restrictions Removed
This policy change is the result of an ARRL complaint filed with the FCC. This will hopefully increase pressure on those causing the interference to comply with established FCC regulations. And it could help the ARRL to further publicize non-compliance.
This article is several weeks old; I just haven't had a good chance to publish the link.
