What is FM radio transmitter?
A personal FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device (such as an MP3 player) to a standard FM radio.
They are often used in cars but may also be in fixed locations such as broadcasting from a computer sound card throughout a building.
