A ONE TRANSISTOR FM TRANSMITTER


Posted on Feb 6, 2014    7579

The 2N2222 circuitry is a three-element, phase-shift oscillator circuit, designed to yield a 1,000-Hz sine wave. The 1,000-Hz sine wave is then applied to the TCG-610 varactor diode, 6 pF at 4 V, which changes the tank capacitance, thus varying the rf oscillator frequency at a 1,000-Hz rate. The 1,000-? potentiometer in the collector circuit can be adjusted..
