88 108 MHz FM Transmitter Circuit88 108 MHz FM Transmitter Circuit
The most important part of this 88-108 transmitter is the Colpitts oscillator. C3,C4,C5,C6,CD1-CD2 ans L1 determine the transmission frequency. The RF Oscillator circuit has the BF982 MosFet transistor wich is the active part. The others 2 transistors separate the VCO from antenna.
