A double superheterodyne system (which converts receive signals twice) improves the image rejection ratio and obtains stable receiver gain. The antenna switching circuit functions as a low-pass filter while receiving and as resonator circuit while transmitting. The circuit does not allow transmit signals to enter receiver circuits. The FM IF IC (IC2) contains the 2nd local oscillator, 2nd mixer, limiter amplifier, quadrature detector, and noise detector circuits, etc. Received signals enter the MAIN unit from the antenna connector and pass through the low-pass filter (L1, L2, C1–C3). The signals are then applied to the RF circuit via the antenna switching circuit (C7, C8, D1, D19, L3). The 1st IF signal from Q3 is applied to the 2nd mixer section of IC1 (pin 16), and is mixed with a 25.25 MHz 2nd LO signal generated at the PLL circuit (IC3, pin 17) to produce a 450 kHz 2nd IF signal. 3-1-2 RF CIRCUIT The RF circuit amplifies signals within the range of frequency coverage and filters out-of-band signals. The 2nd IF signal from IC2 (pin 3) is passed through the ceramic filter (FI2), where unwanted signals are suppressed, and is then applied to the 2nd IF and limiter amplifiers in IC2 (pin 5). The signal is applied to the FM detector section in IC2 for demodulation into AF signals. The signals from the antenna switching circuit pass through a tunable bandpass filter (C10, C12, C13, D2, L4) where the object signals are led to the RF amplifier circuit (Q1). The FM detector circuit employs a quadrature detection method (linear phase detection), which uses a ceramic discriminator (X1) for phase delay to obtain a non-adjusting circuit. The detected signal from IC2 (pin 9) is applied to the AF circuit. The amplified signals at Q1 are applied to the 2-stage tunable bandpass filter (C20, C22, C24, C26, D3, D4, L5, L6) to suppress unwanted signals and improve the selectivity. The signals are then applied to the 1st mixer circuit. D2–D4 employ varactor diodes, that are controlled by the PLL lock voltage, to track the band pass filters. 3-1-5 AF AMPLIFIER CIRCUIT The AF amplifier circuit amplifies the detected signals to drive a speaker. The AF circuit includes an AF mute circuit for the squelch. 3-1-3 1ST MIXER AND 1ST IF CIRCUITS The 1st mixer circuit converts the received signal to a fixed frequency of the 1st IF signal with a 1st LO (VCO output) frequency. By changing the 1st LO frequency, only the desired frequency will be passed through a pair of crystal filters at the next stage of the mixer. AF signals from IC2 (pin 9) are applied to the de-emphasis circuit (R116, C182). The de-emphasis circuit is an integrated circuit with frequency characteristic of –6 dB/octave, and then the integrated signals are applied to the AF amplifier (Q23). The signals from the RF circuit are mixed with the VCO signals at the 1st mixer circuit (Q2) to produce a 21.7 MHz 1st IF signal. The amplified signals are passed through the [VOLUME] control (VR-A unit; R1), and are then applied to the AF power amplifier (IC7, pin 1) via the analog switch (Q24). The output signal from IC7 (pin 4) drives the internal (external) speaker. The 1st IF signal is applied to a pair of crystal filters (FI1 and FI3) to suppress out-of-band signals and is then amplified at the IF amplifier (Q3). The amplified signal is applied to the 2nd mixer circuit (IC2, pin 16). • 2nd IF AND DEMODULATOR CIRCUITS C63 8 R37 R39 7 5 C59 C58 9 10 R30 17 16 2 PLL IC IC3 Mixer Limiter amp.

By detecting noise components in the AF signals, the squelch circuit switches the AF mute switch. The modulation circuit modulates the VCO oscillating signal (RF signal) using the microphone audio signals. Audio signals from the splatter filter (IC5) pass through the frequency deviation adjustment pot (R106) and are then applied to the modulation circuit to modulate the oscillated signal at the VCO (Q7). A portion of the AF signals from the FM IF IC (IC2, pin 9) pass through the [SQUELCH] control pot (VR-B unit; R1) via the “SQLI” signal, and are then applied to the active filter section (IC2, pin 8). The active filter section amplifies and filters noise components. The filtered signals are applied to the noise detector section and output from pin 13 as the “SQL” signal. The “SQL” signal is applied to the CPU (LOGIC unit; IC1, pin 57). The CPU analyzes the noise condition and outputs the “RMUT” signal to an AF mute switch(Q24). 3-2-3 DRIVE AMPLIFIER CIRCUIT The drive amplifier circuit amplifies the VCO oscillating signal to a level needed at the power amplifier. The VCO output is buffer-amplified by Q8 and Q10, and is then applied to the T/R switch (D11). The transmit signal from the T/R switch is amplified to the pre-drive (Q11) and drive (Q12) amplifiers to obtain an approximate 300 mW signal level. The amplified signal is then applied to the RF power amplifier (IC4, pin 1). 3-1-7 WEATHER ALERT DECODER CIRCUIT [USA version only] When the weather alert function is activated and a 1050 Hz alert tone from an NOAA weather radio broadcast is received, the IC-M45A emits beep tones and indicates flashing “ALT” on the display to inform of an emergency weather report on the air. 3-2-4 POWER AMPLIFIER CIRCUIT The power amplifier circuit amplifies the driver signal to an output power level. AF signals from the FM IF IC (IC2, pin 9) are applied to the tone decoder (IC1, pin 3). When a 1050 Hz signal is detected, the tone decoder outputs a low level signal from pin 8 and the output signals are applied to the CPU (LOGIC unit; IC1, pin 41) to control beep tones and the “ALT” indicator. IC4 is a power module which has amplification output capabilities of about 35 W. The output from IC4 (pin 4) is passed through the antenna switching circuit (D19) and is then applied to the antenna connector via the low-pass filter (C1–C3, C5, C6, L1, L2). 3-2 TRANSMITTER CIRCUITS 3-2-5 APC CIRCUIT 3-2-1 MICROPHONE AMPLIFIER CIRCUIT The APC circuit stabilizes transmit output power. The microphone amplifier circuit amplifies audio signals with +6 dB/octave pre-emphasis from the microphone to a level needed at the modulation circuit. The RF output signal from the power amplifier (IC4, pin 4) is detected at the power detector circuit (D13, D14, L21) and is then applied to one of the differential amplifier inputs (Q17, pin 5) via the High/Low control circuit (Q18, R79). The applied voltage controls the differential amplifier output (Q17, pin 2) and the bias voltage control (Q16). Thus the APC circuit maintains a constant output power. The AF signals from the microphone are amplified at the microphone amplifier (IC5). A capacitor (C138) and resistor (R89) are connected to the microphone amplifier (IC5) to obtain the pre-emphasis characteristics. The reflected power from the antenna connector is detected at D14 and is then applied to the CPU (LOGIC unit; IC1, pin 45). The detected voltage increases when the antenna is mismatched, causing the output power to be switched from High to Low to protect the power module (IC4). The amplified signals are passed through the splatter filter (IC5) to suppress unwanted 3 kHz or higher signals. The filtered signals are then applied to the modulation circuit. • APC circuit RF signal from PLL Q12 Drive amp. 1 TMUT L21 Power module 4 IC4 2 3 D13 D14 to antenna RF detector circuit T5 HV Q14 R78 Q16 Q17 R79 Q15 C122 R83 R77 APC control circuit HI/LO Q18 3-2 "TXDET" signal to the CPU 3-3 PLL CIRCUITS 3-3-3 VCO CIRCUIT 3-3-1 GENERAL The VCO outputs from Q7 are buffer-amplified at Q8 and Q10, and are then sent to the T/R switch (D11). The receive LO signal is applied to the 1st mixer circuit (Q2) through a low-pass filter, and the transmit signal is applied to the predrive amplifier (Q11). A portion of the VCO output is reapplied to the PLL IC (IC2, pin 2 or pin 19) via Q9. The PLL circuit provides stable oscillation of the transmit frequency and receive 1st LO frequency. The PLL circuit compares the phase of the divided VCO frequency to the reference frequency. The PLL output frequency is controlled by a crystal oscillator and the divided ratio of the programmable divider. The PLL circuit , using a one chip PLL IC (IC3), directly generates the transmit frequency and receive 1st IF frequency with VCOs. The PLL sets the divided ratio based on serial data from the CPU on the LOGIC unit and compares the phases of VCO signals with the reference oscillator frequency. The PLL IC detects the out-of-step phase and output from pin 13. The reference frequency (21.25 MHz) is oscillated at X2. 3-4 POWER SUPPLY CIRCUITS 3-3-2 TX AND RX LOOP The generated signal at the VCO (C70, C74, L12, D6, D7, Q7) enters the PLL IC (IC3, pin 19) and is divided at the programmable divider section and is then applied to the phase detector section. The phase detector compares the input signal with a reference frequency, and then outputs the out-of-phase signal (pulse-type signal) from pin 13. LINE DESCRIPTION HV The voltage from the connected DC power supply. HVS Same voltage as the HV line which is passed through the [PWR] switch (VR-A unit; R1). 5V Common 5 V converted from the HVS line at the 5V regulator circuit (IC6). R5 Receive 5 V converted from the 5V line at the R5 regulator circuit (Q21, Q22). The regulated voltage is applied to the receiver circuits. T5 Transmit 5 V converted from the 5V line at the T5 regulator circuit (Q19, Q20). The pulse-type signal is converted into DC voltage (lock voltage) at the loop filter (C67, C79, R55, R56), and then applied to variable capacity diodes (D6, D7) of the VCO to stabilize the oscillated frequency. The lock voltage is also used for the receiver circuit for the bandpass filter center frequency. The lock voltage from the loop filter is amplified at the buffer-amplifier (Q8, Q10) and then applied to the RF circuit. • PLL circuit Buffer D11 Q10 Buffer VCO to transmitter circuit to 1st mixer circuit Q8 Buffer Q7, D6, D7 Q9 Loop R55, R56, filter C67, C79 IC3 (PLL IC) 13 21.25 MHz signal to the FM IF IC (IC2, pin 2) 17 X1 21.25 MHz Phase detector Programmable counter Programmable divider 16 3-3 Prescaler Shift register 19 3 4 5 P.STB CK DATA 3-5 PORT ALLOCATIONS 3-5-1 CPU (LOGIC unit; IC1) Pin number Port name Description 41 TONE Input port for the weather alert tone decode signal.
