System reset circuit

IC305 M51951BML is the system reset IC that monitors the power supply voltage. If the voltage falls below the prescribed level, it outputs a reset signal to the main CPU to stop execution and inhibit memory write functions. If the power supply voltage again exceeds the prescribed level when the power is on, the reset signal is released, the main CPU is initialized, and execution is resumed after the time constant of R375 and C379 has elapsed.

Unlock circuit

Normally 8 V 8C is fed to the HET and CAR transistors Q8 and Q27 via Q21. Q21 is on. When any of the PLL loops loop A, B, and C should unlock, pin 8 of the corresponding PLL IC IC3, IC6, IC9 CXD1225M will go H 5V . This causes Q19 to switch on, and Q20 and Q21 to switch off. This action causes the voltage applied to Q8 and Q27 to be removed. Meanwhile Q29 switches on, and LED D10 turns on to indicate the unlocked state. Fig. 4 CAR stop circuit in AM receive mode and PLL unlock circuit Fig. 4...

Receiver system

The receive signal from the ANT terminal passes through the final unit and the TX-RX unit LPF and is applied directly to mixers Q9 and Q10 2SK125-5 . Here the signal is mixed with the first local oscillator frequency 71.395-101.295 MHz from the PLL in order to generate the first IF signal of 71.295 MHz. The receive frequency may be fine tuned with the clarifier by varying the first local oscillator frequency. The 71.295 MHz first IF signal passes through a monolithic filter MCF and is mixed...
