Circuit Description: The amp amplify the audio signal from the MIC, and send it to the compressor. After compressing, the signal is modulated with the carrier wave which is decided by XT1 (25.167MHz ~ 25.778MHz). Then the frequency of carrier signal is doubled by 36 times and amplied. In the end, the signal is transmited over space via antenna.
