CIRCUIT DESCRIPTION

8. Signaling Circuit

8-1. Encode (QT/DQT/DTMF/2TONE/MSK)

Each signaling data signal of the QT, DQT, DTMF, 2TONE

and MSK is generated by the DSP circuit, superposed on a
modulation signal and output from the ASIC (IC507). Each
deviation of the TX QT, DQT, DTMF, 2TONE and MSK tones
are adjusted by changing the output level of the DSP (IC502)
and the resulting signal is routed to the VCO and PLL.

8-2. Decode (QT/DQT/DTMF/2TONE/MSK)

The audio signal is removed from the FM detection signal

sent to the DSP circuit and the resulting signal is decoded by
the DSP.

9. Compander Circuit

The term “compander” means compressor and expander.

The compander reduces noise by utilizing a compressor and
an expander. The DSP (IC502) performs this operation. The
ompander can be turned on or off using the FPU.

10. GPS Circuit (GPS model only)

The GPS information function can be used by setting it

through the FPU. The GPS signal of 1575.42MHz received
with the GPS active antenna (with a built-in LNA) is processed
by the GPS module (A801) and input to the ASIC (IC507)
through the UART port. The ASIC (IC507) processes the GPS
data (NMEA) and sends the resulting information to the LCD.
