2.4.8 Signaling Circuit
2.4.8.1 Encode (QT/DQT/DTMF/2-tone/MSK)
Each signaling data signal of QT, DQT, DTMF, 2-tone and MSK is generated by IC702, superposed on a modulation signal and is sent
to TX VCO and TX PLL IC.
2.4.8.2 Decode (QT/DQT/DTMF/2-tone/MSK)
The audio signal is removed from the FM detection signal sent to the IC702 and the resulting signal is decoded by IC702.
