    SECTION 5 CIRCUIT DESCRIPTION 5-1 RECEIVER CIRCUITS The converted 1st IF signal is passed through the 1st IF fi lter (in wide mode; FI1, in narrow mode; FI4) via the bandwidth 5-1-1 ANTENNA SWITCH (MAIN and RF UNITS) switch (D34), to remove adjacent signals. The filtered signal The received signals from the antenna connector are passed is applied to the 1st IF amplifi...

    The TX/RX HPF filters out 250 Hz and lower audio signals, • CTCSS/DTCS and the de-emphasis circuit obtains –6 dB/oct of audio A portion of the demodulated AF signals are passed through characteristics. The expander expands the compressed audio the active LPF (Q28) to filters CTCSS/DTCS signal. The filtered signals and also noise reduction function is provided.

    The output AF signals are then passed through the Digital/ A portion of the transmit signal is detected by the transmit power Analog switch (IC14, pins 12, 14) and applied to the AF mixer detector (D604, D607) to produce a DC voltage corresponding to (IC9, pin 6) where the MIC signals and Tone signals are mixed the transmit output power level.

    The buffer-amplifi ed VCO output signals from the tunable BPF If the oscillated signal drifts, its phase changes from that of (L601−L603, C601−C607) are applied to the PLL IC (IC1, the reference frequency, causing a lock voltage change to pin 6). The applied signals are divided at the prescaler and compensate for the drift in the VCO oscillating frequency.
