Posted on Feb 7, 2014

By using only two 2n2222 transistors, this small FM band transmitter can transmit its signal to 1Km away (without obstacles between the two antennas.

The first stage of the circuit you see the Mic preamplifier state with the first 2n2222. The next state with the other 2n2222 is the transmitting stage. All success is based on the type of antenna that you are going to use with it. A 9 volts battery can drive the circuit for few hours. If you need longer times just use a 9v power supply.
