Telephone FM Transmitter

Product Description

This low cost FM transmitter is connected in series with your telephone line using the included modular telephone cables. It transmits the telephone conversation over the FM band when you pick up the telephone handset connected to it and the transmitted signal can be tuned by any FM receiver. The circuit includes an "On Air" LED indicator and also provides a switch that can be used to turn off the transmitter. A unique feature of the circuit is that no battery is needed to operate the circuit since power is taken from the telephone line. The transmitter uses only a short wire antenna since.

Important Notice:

In some countries it is illegal to listen to a telephone conversation without the consent of all parties involved. This device is designed for educational use only.
