NEVER connect the transceiver to an AC outlet or to a DCpower supply that uses more than 16 V. This will ruin thetransceiver.DO NOT expose the transceiver to rain, snow or any liquids.DO NOT reverse the polarities of the power supply whenconnecting the transceiver.DO NOT apply an RF signal of more than 20 dBm (100mW)to the antenna connector. This could damage the trans-ceiver's front end.
REPAIR NOTES
1. Make sure a problem is internal before disassemblingthe transceiver.
2. DO NOT open the transceiver until the transceiver is dis-connected from its power source.
3. DO NOT force any of the variable components. Turnthem slowly and smoothly.
4. DO NOT short any circuits or electronic parts. An insulat-ed turning tool MUST be used for all adjustments.
5. DO NOT keep power ON for a long time when the trans-ceiver is defective.
6. DO NOT transmit power into a signal generator or asweep generator.
7. ALWAYS connect a 40 dB to 50 dB attenuator betweenthe transceiver and a deviation meter or spectrum ana-lyzer when using such test equipment.
8. READ the instructions of test equipment thoroughlybefore connecting equipment to the transceiver.

SECTION 3 CIRCUIT DESCRIPTION
3 - 1
3-1 RECEIVER CIRCUITS3-1-1 ANTENNA SWITCHING CIRCUITThe antenna switching circuit functions as a low-pass filterwhile receiving and as resonator circuit while transmitting.The circuit does not allow transmit signals to enter receivercircuits.
Received signals enter the MAIN unit from the antenna con-nector and pass through the low-pass filter (L1–L3, C1–C5,C7). The signals are then applied to the RF circuit via theantenna switching circuit (D1, L4, L25).
3-1-2 RF CIRCUITThe RF circuit amplifies signals within the range of frequen-cy coverage and filters out-of-band signals.
The signals from the antenna switching circuit pass througha tunable bandpass filter (D2, L5) where the object signalsare led to the RF amplifier circuit (Q1).
The amplified signals at Q1 are applied to the 2-stage tun-able bandpass filter (D3, D4, L6, L7) to suppress unwantedsignals and improve the selectivity. The signals are thenapplied to the 1st mixer circuit.
D2–D4 employ varactor diodes, that are controlled by thePLL lock voltage, to track the band pass filters.
3-1-3 1ST MIXER AND 1ST IF CIRCUITSThe 1st mixer circuit converts the received signal to a fixedfrequency of the 1st IF signal with a 1st LO (VCO output) fre-quency. By changing the 1st LO frequency, only the desiredfrequency will be passed through a pair of crystal filters atthe next stage of the mixer.
The signals from the RF circuit are mixed with the VCO sig-nals at the 1st mixer circuit (Q2) to produce a 30.85 MHz 1stIF signal.
The 1st IF signal is applied to a pair of crystal filters (FI1) tosuppress out-of-band signals and is then amplified at the IFamplifier (Q3). The amplified signal is applied to the 2ndmixer circuit (IC1).
3-1-4 2ND IF AND DEMODULATOR CIRCUITSThe 2nd mixer circuit converts the 1st IF signal to a 2nd IFsignal. A double superheterodyne system (which convertsreceive signals twice) improves the image rejection ratio andobtains stable receiver gain.
The FM IF IC (IC1) contains the 2nd local oscillator, 2ndmixer, limiter amplifier, quadrature detector, and noisedetector circuits, etc.
The 1st IF signal from Q3 is applied to the 2nd mixer sectionof IC1 (pin 16), and is mixed with a 30.4 MHz 2nd LO signalgenerated at the PLL circuit by doubling the reference fre-quency (15.2 MHz) to produce a 450 kHz 2nd IF signal.
The 2nd IF signal from IC1 (pin 3) is passed through theceramic filter (FI2), where unwanted signals are sup-pressed, and is then applied to the 2nd IF and limiter ampli-fiers in IC1 (pin 5). The signal is applied to the FM detectorsection in IC1 for demodulation into AF signals.
The FM detector circuit employs a quadrature detectionmethod (linear phase detection), which uses a ceramic dis-criminator (X2) for phase delay to obtain a non-adjusting cir-cuit. The detected signal from IC1 (pin 9) is applied to the AFcircuit.
3-1-5 AF AMPLIFIER CIRCUITThe AF amplifier circuit amplifies the detected signals todrive a speaker. The AF circuit includes an AF mute circuitfor the squelch.
AF signals from IC1 (pin 9) are applied to the de-emphasiscircuit (R92, C152). The de-emphasis circuit is an integratedcircuit with frequency characteristic of –6 dB/octave.
The integrated signals are applied to the active filters (Q21,Q22). Q21 functions as a high-pass filter to suppressunwanted lower noise signals and Q22 functions as a low-pass filter to suppress higher noise signals.
The filtered signals are passed through the [VOLUME] con-trol, and are then applied to the AF power amplifier (IC9, pin1) via the analog switch (IC5, pins 4, 3). The output signalfrom IC9 (pin 4) drives the internal (external) speaker.

3-1-6 SQUELCH CIRCUITA squelch circuit cuts out AF signals when no RF signals arereceived. By detecting noise components in the AF signals,the squelch circuit switches the AF mute switch.
A portion of the AF signals from the FM IF IC (IC1, pin 9)pass through the [SQUELCH] control pot, and are thenapplied to the active filter section (IC1, pin 8). The active fil-ter section amplifies and filters noise components. The fil-tered signals are applied to the noise detector section andoutput from pin 13 as the “SQL” signal. The “SQL” signal isapplied to the CPU (LOGIC unit; IC1, pin 22). The CPU ana-lyzes the noise condition and outputs the RMUT signal viathe I/O expander IC (IC7) to toggle the analog switches (IC5,pins 4, 3) as an AF mute switch.
3-1-7 WEATHER ALERT DECODER CIRCUIT[USA version only]
When the weather alert function is activated and a 1050 Hzalert tone from an NOAA weather radio broadcast isreceived, the IC-M45 emits beep tones and indicates flash-ing “ALT” on the display to inform of an emergency weatherreport on the air.
AF signals from the FM IF IC (IC1, pin 9) are applied to thetone decoder (IC10, pin 3). When a 1050 Hz signal is detect-ed, the tone decoder outputs a low level signal from pin 8and the output signals are applied to the CPU (LOGIC unit;IC1) to control beep tones and the “ALT” indicator.
3-2 TRANSMITTER CIRCUITS3-2-1 MICROPHONE AMPLIFIER CIRCUITThe microphone amplifier circuit amplifies audio signals with+6 dB/octave pre-emphasis from the microphone to a levelneeded at the modulation circuit.
The AF signals from the microphone are amplified at themicrophone amplifier (IC4). A capacitor (C135) and resistor(R114) are connected to the amplifier to obtain the pre-emphasis characteristics.
The amplified signals are applied to the IDC amplifier (IC6a,pin 2) via the analog switch (IC5, pins 8, 9) and are passedthrough the splatter filter (IC6b) to suppress unwanted 3 kHzor higher signals. The filtered signals are then applied to themodulation circuit.
3-2-2 MODULATION CIRCUITThe modulation circuit modulates the VCO oscillating signal(RF signal) using the microphone audio signals.
Audio signals from the splatter filter (IC6b) pass through thefrequency deviation adjustment pot (R130) and are thenapplied to the modulation circuit (D7) to change the reac-tance of D7, and modulate the oscillated signal at the TX-VCO (Q4).
3-2-3 DRIVE AMPLIFIER CIRCUIT The drive amplifier circuit amplifies the VCO oscillating sig-nal to a level needed at the power amplifier.
The VCO output is buffer-amplified by Q7 and Q9, and isthen applied to the T/R switch (D9). The transmit signal fromthe T/R switch is amplified to the pre-drive (Q10) and drive(Q11) amplifiers to obtain an approximate 400 mW signallevel. The amplified signal is then applied to the RF poweramplifier (IC2).
3-2-4 POWER AMPLIFIER CIRCUITThe power amplifier circuit amplifies the driver signal to anoutput power level.
IC2 is a power module which has amplification output capa-bilities of about 35 W. The output from IC2 (pin 4) is passedthrough the antenna switching circuit (D13) and is thenapplied to the antenna connector via the low-pass filter.
3-2-5 APC CIRCUITThe APC circuit stabilizes transmit output power.
The RF output signal from the power amplifier (IC2) isdetected at the power detector circuit (D11, D12, L22) and isthen applied to one of the differential amplifier inputs (Q13,pin 5) via the High/Low control circuit (R70, R71, Q16). Theapplied voltage controls the differential amplifier output(Q17, pin 2) and the bias voltage control (Q12). Thus theAPC circuit maintains a constant output power.
The reflected power from the antenna connector is detectedat D12 and is then applied to the CPU. The detected voltageincreases when the antenna is mismatched, causing theoutput power to be switched from High to Low to protect thepower module (IC2).

3-3 PLL CIRCUITS3-3-1 GENERALThe PLL circuit provides stable oscillation of the transmit fre-quency and receive 1st LO frequency. The PLL circuit com-pares the phase of the divided VCO frequency to the refer-ence frequency. The PLL output frequency is controlled by acrystal oscillator and the divided ratio of the programmabledivider. IC3 is a dual PLL IC which controls both VCO cir-cuits for Tx and Rx.
The PLL circuit , using a one chip PLL IC (IC3), directly gen-erates the transmit frequency and receive 1st IF frequencywith VCOs. The PLL sets the divided ratio based on serialdata from the CPU on the LOGIC unit and compares thephases of VCO signals with the reference oscillator fre-quency. The PLL IC detects the out-of-step phase and out-put from pins 8 and 13 for Tx and Rx, respectively. The ref-erence frequency (15.2 MHz) is oscillated at X1.
3-3-2 TX LOOPThe generated signal at the TX-VCO (Q4, D6, D7) entersthe PLL IC (IC3, pin 2) and is divided at the programmabledivider section and is then applied to the phase detectorsection.
The phase detector compares the input signal with a refer-ence frequency, and then outputs the out-of-phase signal(pulse-type signal) from pin 8.
The pulse-type signal is converted into DC voltage (lockvoltage) at the loop filter (R41–R43, C75–C77), and thenapplied to varactor diodes (D6, D7) of the TX-VCO to stabi-lize the oscillated frequency.
3-3-3 RX LOOPThe generated signal at the RX-VCO (Q5, D8) enters thePLL IC (IC3, pin 19) and is divided at the programmabledivider section and is then applied to the phase detectorsection.
The phase detector compares the input signal with a refer-ence frequency, and then outputs the out-of-phase signal(pulse-type signal) from pin 13.
The pulse-type signal is converted into DC voltage (lockvoltage) at the loop filter (R34, R37, R38, C64, C73), andthen applied to varactor diode (D8) of the RX-VCO to stabi-lize the oscillated frequency. The lockvoltage is also used forthe receiver circuit for the bandpass filter center frequency.The lock voltage from the loop filter is amplified at the buffer-amplifier (Q6) and then applied to the RF circuit.
3-3-4 VCO CIRCUITThe VCO outputs from Q4 (Tx) and Q5 (Rx) are buffer-amplified at Q7 and Q9, and are then sent to the T/R switch(D9). The receive LO signal is applied to the 1st mixer circuit(Q2) through a low-pass filter, and the transmit signal isapplied to the pre-drive amplifier (Q10). A portion of the VCOoutput is reapplied to the PLL IC (IC10, pin 2 or pin 13) viaQ8.
