Friday, August 01, 2003's follow-up on today's powerline broadband/amateur radio articles's follow-up on today's powerline broadband/amateur radio articles

"Members of the Amateur Radio community, with a little help from their friends, have gathered $193,000 from more than 3690 donors to help battle a technology that could throw a stick in the spokes of thier hobby. BPL (broadband over powerlines, also dubbed PLC) operates on frequencies between 2 and 80 MHz, potentially causing problems with HF and low-VHF amateur allocations."

This article includes links to the stories I noted earlier and is followed by an intense discussion between amateur radio operators and powerline broadband advocates.

It's worth noting that there are other users of the radio spectrum between 2 and 80 MHz in the United States. The National Telecommunications and Information Administration has a downloadable chart showing the other frequency users. Amateur radio uses only a small percentage of the HF (high frequency) and VHF (very high frequency) bands over the 2 to 80 MHz range. The rest of the spectrum is allocated to maritime radio, mobile radio, unspecified federal government use (military?), space research, radio astronomy, shortwave broadcasters, aeronautical radionavigation and the lowest TV channels starting with channel 2. Many of these users have also filed comments with the FCC in its inquiry into powerline broadband.

You can review the comments on the FCC site; use the FCC search form and enter "03-104" as the proceeding number. As of today, 2136 responses were on file. To cut to the chase, the ARRL (American Radio Relay League) has posted links to many of the filings on both sides of the issue on a special web page.
