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 .
