10. The CPU IC9 is equipped with an internal DTMF encoder The DTMF signal is output from pin 10 through R102 and R158 for level adjust ment and then through the microphone amplifier IC7 and is sent to the varicap of the VCO for modulation At the same time the monitor ing tone passes through the AF circuit and is output form the speaker 6 CTCSS Encoder The CPU IC9 is equipped with an internal tone encoder The tone signal 67 0 to 250 3 Hz is output form pin 9 ofthe CPU to the varicap D3 of the VCO for modulation 5 5 6 Tone Encoder The CPU 109 is equipped with an internal tone encoder The tone signal 67 0 to 250 3Hz is output from pin 9 of the CPU to the varicap D3 of the VCO for modulation 7 DCS Encoder The CPU IC9 is equipped with an internal DCS code encoder The code 023 to 754 is output from pin 9 of the CPU to the varicap D3 of the PLL reference oscillator When DCS is ON DCS MUTE circuit Q15 ON Q18 ON Q16 OFF works The modulation activates in X1 side only 8 CTCSS DCS Decoder The voice band of the AF output signal from pin 10 of IC5 is cut by sharp active filter IC8 VCVS and amplified then led to pin 4 of CPU The input signal is compared with the programmed tone frequency code in the CPU The squelch will open when they match 9 Clock Shift In the unlikely event that CPU clock noise is present on a particular operating frequency programmed into the radio you can shift the CPU clock freque
