About The Circuit: These is the exact description of Art Swan, the circuit's Author, "This miniature transmitter is easy to construct and can be picked up on any standard FM receiver. It has a range of up to 1/4 mile or more.
Stereo FM Transmitter with BA1404
BA1404 is a IC designed for fm mini stereo transmitters. It can be used as a pc fm transmitter, ipod fm transmitter, mp3 transmitter or even car fm transmitter because it has a small pcb dimension ( can fit anyplace ) and maximum 3V power supply. It has a good frequency stability due the high quality 3.5 turns coil and a crystal clear stereo.

The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation (FM) transfers the information by varying the frequency of the carrier wave according to the message signal. Generally, the FM transmitter uses VHF radio frequencies of 87.5 to 108.0 MHz to transmit & receive the FM signal.
