NEWINGTON, CT, Jan 18, 2006--After the operator of the Manassas, Virginia, BPL system failed to meet its own commitment to resolve complaints of interference to local radio amateurs, the ARRL again demanded the system's immediate shutdown. Writing on the League's behalf, ARRL General Counsel Chris Imlay, W3KD, told the FCC January 17 that Communications Technologies (COMTek), which operates the BPL system over the municipally owned electric power grid using Main.net equipment on frequencies between 4 MHz and 30 MHz, "has been given every opportunity" over the past 18 months to resolve interference complaints.
"It is now apparently unwilling to voluntarily comply with its regulatory obligation to shut the system down," Imlay said of COMTek, following a meeting January 17 between company officials and local radio amateurs. An ARRL representative also attended. Imlay said the meeting's outcome dictates "the urgency of the Commission's obligation to finally take action to stop the unlawful operation of the Manassas BPL system."
The League asserts that COMTek did not want to start the meeting with a local newspaper reporter present. Imlay said the company's "bizarre action" indicated that COMTek "was unwilling to subject itself to public scrutiny."
COMTek Vice President Walter Adams acknowledged at this week's meeting that its BPL system was causing harmful interference on Amateur Radio frequencies, despite its pledge to permanently notch ham bands by January 15, the League said. Even so, Adams "specifically declined to take any further steps to mitigate the interference," Imlay continued, calling COMTek's stance "totally unacceptable to the aggrieved licensees in Manassas."
In its letter, the League said it doesn't question COMTek's desire to eliminate the harmful interference. "However, the inescapable fact is that the Main.net hardware now in use in the city's BPL system is, and has been proven, incapable of being configured so as to function as intended without causing harmful interference to radio communication."
The League addressed its latest correspondence in the Manassas situation to FCC Spectrum Enforcement Division Chief Joseph Casey and to Katherine Power, an attorney in the division. Copies went to local radio amateurs George Tarnovsky, K4GVT, Donald Blasdell, W4HJL, and William South, N3OH, as well as to Manassas Journal newspaper reporter Jaclyn Pitts, COMTek and its attorneys, and the City of Manassas.
"Because COMTek has declined to do so voluntarily, it is imperative that the FCC order the system immediately to cease operation, in accordance with §15.5(c) of the Commission's rules," Imlay's letter concluded, "and that operation not resume unless and until new hardware is installed that is capable of operating without causing harmful interference."
Less than a month ago, the League called on the FCC to shut down the Manassas BPL system in another strongly worded letter. That communication was in response to a November 30 letter from Casey, who'd suggested further cooperation between the complaining radio amateurs and the city-owned BPL system.
"These meetings have not produced any solution to the interference problem but have, instead, created the illusion that the problem is being addressed," Imlay charged in his reply. Ham radio complaints of interference from the BPL system date back to early 2004.
A petition the League filed earlier last fall seeks to have the FCC modify the Part 15 BPL rules it adopted in 2004 to embrace more mature BPL technology with substantially less potential to interfere. Among BPL systems more likely to be involved in stubborn interference cases, the ARRL said, are those using DS2 or Main.net technology that lack fixed, permanent notches in the ham bands. Utilization of such BPL technology, the League maintains, has resulted in "substantial, extremely difficult-to-resolve incidents of interference" from BPL pilot programs and deployments to Amateur Radio.
