The Revolution Will Be Televised
From Free Radio to Free TV Broadcasting
It is now time to “Turn on, tune in and take over”. 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 Berkeley’s 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. Estimated cost for a VHF transmitter and antenna system with an effective radiated power of 75 watts is about $500 (cost of kits & modulator), $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.
TV Broadcasting kits are now available, check the store catalog for kits. Any composite video source with an audio out signal can be used by the TV transmitters.

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.
