Late last month, the ARRL filed a complaint with the FCC, documentingongoing harmful interference and egregious rules violations byBroadband over Power Lines (BPL) systems installed by IBEC, Inc. inVirginia, Pennsylvania and Indiana. In its filing, the ARRL requestedthat the FCC "initiate immediately an enforcement proceeding regardingthese BPL systems, and cause them to cease operation until such time asthey are each in full compliance with the Commission's Rules."

Contrary to earlier representations -- both to the ARRL and instatements in the online BPL database -- IBEC's systems in theselocations are not universally notching the amateur bands as isnecessary in order to avoid emissions at levels that are likely tocause harmful interference to licensed Amateur Radio stations. In fact,measurements by ARRL staff that were independently confirmed show thatIBEC systems are not even notching the aeronautical bands. The FCCrules require BPL systems to avoid these bands, but IBEC is operatingat power levels that cause radiation well in excess of the FCC limits.Read more here http://www.arrl.org/news/arrl-shows-ibec-bpl-systems-are-interfering-violating-fcc-rules.
