SECTION 3 CIRCUIT DESCRIPTION 3 - 1 3-1 RECEIVER CIRCUITS 3-1-1 RF CIRCUIT (RX UNIT ) Received signals from the RX antenna connector enter the RX unit J1 and pass through a tuned bandpass filter (D3, D4, L2, L3, C5–C8, C12, C13, C205, C206, C220, 221) which is controlled by the D/A converter IC (LOGIC unit; IC25).
3 - 2 3-1-6 RECEIVER MUTE CIRCUITS (LOGIC UNIT) • NOISE SQUELCH The noise squelch circuit cuts out AF signals when no RF signals are received. By detecting noise components in the AF signals, the squelch circuit switches the AF mute switch.
3 - 3 The filtered signals are applied to the limiter amplifier (IC3), and are then mixed with the DTMF signal from the CPU (IC33, pin 43) via the TX-signal filter (IC3, pins 8, 10, 12, 14). The mixed signals are applied to the splatter filter (IC4), and are then applied to the P A unit.
3 - 4 detected voltage exceeds the power setting voltage. Then the output voltage of the APC amplifier IC (IC1, pin 4) con- trols the input current of the drive amplifier (Q4) and power amplifier IC (IC2, pin 2) to reduce the output power .
3 - 5 3-4 OTHER CIRCUIT S 3-4-1 TELEPHONE IF CIRCUIT (LOGIC UNIT) The signals from the telephone line (FRONT , J13) are applied to the ringer detect circuit (IC48, D1, D5, R131, R143, R145, C100, C103, C375). The detected signals are applied to the CPU (IC33, pin 73) via “RING” line.
Input port for the strobe signal. Input port for the clock signal. Outputs the serial data to the CPU (LOGIC unit; IC33). Input port for the received AF signal. Outputs the adjusted AF signal for the repeater output. Outputs the adjustment signal for the PLL reference frequency on the RX unit.
3 - 7 Outputs the strobe signal for the PLL IC on the RX unit. Outputs the strobe signal for the PLL IC on the TX unit. Input port for the unlock signal from the PLL IC on the TX unit. Outputs the TX mute signal for the TX unit. Outputs the TX mute signal for the P A unit.
3 - 8 Outputs the strobe signal for the port expander IC (LOGIC unit; IC41). Outputs the strobe signal for the port expander IC (LOGIC unit; IC40). Outputs the strobe signal for the port expander IC (LOGIC unit; IC39). Outputs the strobe signal for the D/A converter IC (LOGIC unit; IC25).
4 - 1 4-1 PREP ARA TION Some adjustments must be performed on the “ADJUSTMENT MODE”. CS-FR3000 CLONING SOFTW ARE , OPC-478 CLONING CABLE and OPC-592 ADAPTOR CABLE are required when entering the adjustment mode.
■ BEFORE ENTERING THE ADJUSTMENT MODE CAUTION!: Need to back up the original memory data using CS-FR3000 before cloning the adjustment frequencies. When program the adjustment frequencies into the repeate r , the repeate r ’ s memor ies channels will be overwritten the data and deleted original memory data at the same time.
