Long Range FM Transmitter With Audio Modulation

Model No.189: The aim of this project is to develop a low cost long range FM Transmitter with audio modulation. The FM transmitter has 3 stages, A (VFO) Variable frequency Oscillator (30 mw), a class C driver stage (150 mw) and a class C final power amplifier (1 Watt). Basically every FM Transmitter has to have a Voltage Controlled Oscillator (VCO). This is a high frequency oscillator whose output frequency changes based on the voltage applied at a particular control point.
