FM Transmitter

Description

The wireless frequency modulated (FM) transmitter module enables users to play a portable audio source through any FM radio, such as a vehicle stereo. This FM Transmitter DIY Kit has no physical connection to the radio, hence no upgrade of an audio system is required. The driver should find an empty band on the FM spectrum;  otherwise, the audio clashes with live radio broadcasts.

A converter takes the audio output of an external source into analog audio. The audio is then converted once more, this time into an FM signal, through FM modulation. FM Transmitter Science Kits drivers can adjust their car radio to the transmitter's precise frequency and listen to music on the FM band as if it were broadcasting from a regular FM station.
