Donate to Free Radio Berkeley
As of January 2017, the Free Radio Berkeley project was 24 years old. We keep our prices low so that most anyone can afford to have a voice - and offer technical support, classes and training as well. In order to continue our efforts to preserve and expand Free Speech on the airwaves through rather difficult economic and political times, your financial support is needed. Please make a donation to Free Radio Berkeley.
Free Radio: How to do it!
We will be adding further instructional videos and slide shows on both Free Radio and TV. Go the technical libary section. Some of the currently available documents:

Summer Radio Camp 2017 - September 1 to September 4
A four day DIY workshop session sponsored by Free Radio Berkeley in which you learn how to build either a 10, 40 or 150 watt FM broadcast (88-108 MHz, standard FM band) transmitter (and other related items such as antennas) and set up a low power community radio station capable of covering a broadcast radius up to 10-15 miles depending on terrain and antenna height.
With an emphasis on direct, hands-on learning, you will learn how to solder, identify electronic components, assemble an FM broadcast transmitter from a kit of parts, build and tune an antenna, properly setup and test broadcast equipment and much more. Further, you will be given an overview of basic electronics and broadcast engineering.
A workshop fee of $200 to $300 sliding scale is charged. At the end of the radio camp session you may purchase the 40 watt transmitter for $450 or the 10 watt transmitter for $300 or the 150 watt transmitter for $650 - the cost of the kit, power supply and enclosure. An entry level 10 watt transmitter kit made in China is available for $60. All participants will assemble an AM/FM radio kit which is included in the workshop fee.
The camp is open to anyone 16 years and older. The Radio Camp session runs Friday through Monday (10 a.m. to 6 p.m.). It will be held at FRB’s shop in Rodeo,CA September 1 - 4, 2017

Complete Plug and Play FM Broadcast Transmitter Packages Now Available!
10 Watt - Coverage radius up to 4-5 miles (6.5-8.5 kilometers)
40 Watt - Coverage radius up to 8-10 miles (12-15 kilometers)
150 Watt - Coverage radius up to 15 miles (25 kilometers)
All packages include transmitter, power supply, Comet 5/8 ground plane antenna and 50 feet of low loss coaxial cable. The Comet antenna has a power gain of 2. This means that the antennaa effectively doubles whatever power is fed to it. If you wish to double the radius of coverage, the power has to be increased by a factor of 4 and the antenna raised to a height that will provide the required distance to horizon. FM transmission is line of sight - both the transmitting and receiving antenna must be able to "see" each other. The radius of coverage as stated above assumes average flat terrain with an antenna positioned at least 40 to 50 feet (12-15 meters) above the ground. As it is said, "You mileage may vary".
These are plug and play packages. Add an audio mixer, compressor limiter, microphones, etc. for a complete radio station. In many cases, with the proper hardware and software a computer system can provide most of these functions. Cue up a mix of mp3/podcast content, live streams, etc., feed the audio output from the computer to the transmitter and bring fresh voices, news/information and music to your neighborhood and community.

Islands of Resistance - Pirate Radio in Canada
by Andrea Langlois, Ron Sakolsky & Marian van der Zon
While only recently have we heard the major networks broadcast warnings of rising sea levels, since radio’s invention certain Canadians have been concerned by the increasingly centralized medium and its commercial flooding of the airwaves. Occasionally alone, frequently in teams and always illegally, these activists are islands of resistance within theocean of homogenous frequencies, pirating radio signals for personal, political and artistic expression.
In the first book published on the subject, Islands of Resistance gives you a view from the crowsnest of the phenomenon of pirate radio in Canada. Here is a collection of seventeen activist manifestos, artistic treatise of intent, historical essays on the development of radio and its regulatory bodies, sociological examination of pirate radio’s application in new social movements, and personal anecdotes from behind the eyepatch.
Just as the new media ostenibly renders the old obsolete, Islands of Resistance unveils the existance of a thriving clandestine counterculture. An invaluable addition to an unscrutinized subject in Canadian media studies, Islands of Resistance appeals to the anarchist, anti-authoritarian impulses inall of us.
Pirate Radio in London
Pirate radio is everywhere in London, born in the 60’s from rusting anti-aircraft towers in the mouth of the Thames. Today’s broadcasts are hidden in plain sight, transmitting from secret tower block studios via homemade rooftop antennas.
Radio Nomndaa La Palabra Del Agua
In July, 2008 Federal Police attempted to shut down Radio Nomndaa located in the Mexican state of Guerrero but were prevented from doing so by the community standing in solidarity to protect their community radio station. So far, the station remains on the air. En Espanol
The Revolution Will Be Televised - From Free Radio to Free TV Broadcasting
With the transition from analog to digital TV broadcasting underway, it is now time to Turn on, tune in and take over the soon to be vacant analog TV spectrum. Finally, guerilla media activists will be able to say:
There is nothing wrong with your television set. Do not attempt to adjust the picture. We are controlling transmission. If we wish to make it louder, we will bring up the volume. If we wish to make it softer, we will tune it to a whisper. We will control the horizontal. We will control the vertical. We can roll the image, make it flutter. We can change the focus to a soft blur or sharpen it to crystal clarity. For the next hour sit quietly and we will control all that you see and hear. We repeat: there is nothing wrong with your television set. You are about to participate in a great adventure. (Outer Limits intro circa 1963)
Free Radio Berkeleys engineering staff have designed and developed 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. Amplifers capable of covering an even greater distance will be available in the first quarter of 2006. The cost for an assembled VHF or UHF transmitter and antenna system with an effective radiated power of 75 watts is $750, ($550) as a kit (cost of kits & modulator) and $850(kit) / ($1250 (assembled) for a system with an effective radiated power of 400 watts. Coverage pattern is 120 degrees, not fully omni-directional. Higher power versions are available, please inquire. Further work is continuing on the development of antenna systems.
Check the store catalog for kits. Any composite video source with an audio out signal can be used by the TV transmitters. Click here for a typical TV broadcast configuration diagam. Typically, most folks will most likely use a multiple disk DVD player or a computer with video files on a large capacity hard drive. Live broadcasts are certainly a possibility. This would require several video cameras and a video switcher/mixer.
A 200-disk DVD juke box style player would be able contain almost two weeks worth of material, assuming two hours per DVD. Considering the quantity of video material available, most of which will never be seen on either broadcast TV or cable/satellite feeds, there should not be any problem providing audiences with an exciting and compelling selection of material.
No doubt, the FCC, the National Association of Broadcasters and other entrenched interests will most strenuously object to Micropower or Free TV Broadcasting. What better way to respond to the total propaganda environment that has been created with television media.
