- Page 4 MINIATURE RADIO TRANSMITTER The TV/FM Oscillator is really a miniature radio transmitter. The oscillator transmits an unmodulated (no audio message) carrier frequency between 50MHz - 200MHz, to a distance of 5 to 30 feet. Your TV/FM is designed to receive a signal in this frequency range. While your miniature radio transmitter puts out a very weak signal at close range, it is strong enough to override the standard broadcast stations.
- Page 5 CONSTRUCTION Introduction The most important factor in assembling your K-29 TV/FM Oscillator Kit is good soldering techniques. Using the proper soldering iron is of prime importance. A small pencil type soldering iron of 25 - 40 watts is recommended. The tip of the iron must be kept clean at all times and well tinned.
