APPLICATION SCHEMATIC
The Electret Condenser Microphone is biased with MIC-BIAS1 voltage. The audio signal is transmitted on
the left channel using a 2.8 MHz carrier. The VOX activates the transmitter TX1 when the audio signal is
present. The audio signal at line level is attenuated and is transmitted by the second transmitter TX2 at
2.3 MHz.
