Free Radio Berkeley Unveils Micro-TV Kits

Stephen Dunifer recently sent out an e-mail titled “The Revolution Will Be Televised,” which said, in part:

Free Radio Berkeley’s engineering staff has managed to design and develop low power VHF and UHF transmitters by the creative use of off-the-shelf technology. So far, design engineering efforts have yielded TV transmitters capable of reaching a distance of 4-5 miles. Estimated cost for a VHF transmitter and antenna system with an effective radiated power of 75 watts is about $500, $700 to $800 for a system with an effective radiated power of 400 watts. For a UHF system, add about $300 to the above amounts. Coverage pattern is 220 degrees, not fully omni-directional. Further work is continuing on the development of antenna systems…. Read More

Dunifer Publishes New Version of Micropower Broadcasting: A Technical Primer

Free Radio Berkeley founder Stephen Dunifer updates his easy-to-read handbook with information on digital audio production and webcasting and the new realities of operating a microradio station in post-millenial America. Download it here (632K, .pdf format).

Its 25 pages are packed with useful information that thoroughly describes what you need to operate your basic microradio station and the general science behind FM broadcasting. It also includes schematics and circuit board layouts for most major components.

After moving his workshop last year, Dunifer is now also offering the use of his facilities for anyone interested in building their own rigs. It sounds like the 3-5 day project is a more detailed version of the transmitter-building workshops Dunifer and his crew have frequently run in the past.

Strategy Session

During the last weekend in May, while many Americans were relaxing at the expense of those who gave their lives for their freedom, soldiers in a lower-profile domestic war gathered to plot their next moves in their fight.

The “Micropower Council of War” was called by Free Radio Berkeley founder Stephen Dunifer; if it were not for his ongoing battle with the government (through the courts), there would have been no blossoming of unlicensed radio stations – and no widespread microradio movement.

When the FCC announced its plans to re-legalize a low power FM (LPFM) radio service, Dunifer was one of the first to discount the move as political hype. Read More
