mini fm transmitter circuit


Posted on Feb 5, 2014

Here is the mini FM transmitter circuit using 2 transistor. Audio sensitivity is very good when used with an ECM type microphone insert. This smallFM transmitteruses a hartley type oscillator. Normally the capacitor in the tank circuit would connect at the base of the transistor, but at VHF the base emitter capacitance of the t

ransistor acts as a short circuit, so in effect, it still is. The FM transmitter coil is four turns of 18swg wire wound around a quarter inch former.
