TX-FM AUDIO

  Transmitter Module

The TX-FM audio transmitter module is designed for use with the 

RX FM AUDIO

 receiver module and is

typically suited to applications such as  Hi-Fi quality audio transmission, radio call alert, two way radio,
security, remote control (DTMF) systems and analog telemetry .
