[. . . ] This could damage the transceiver's front end. To upgrade quality, any electrical or mechanical parts and internal circuits are subject to change without notice or obligation. ORDERING PARTS Be sure to include the following four points when ordering replacement parts: 1. Quantity required <SAMPLE ORDER> 1140005990 S. IC MB15A02PFV-1 IC-21A MAIN UNIT 5 pieces 8810009610 Screw FH M2. 6×6 ZK IC-21A Bottom cover 10 pieces REPAIR NOTES 1. DO NOT open the transceiver until the transceiver is disconnected from its power source. DO NOT keep power ON for a long time when the transceiver is defective. [. . . ] The PLL output frequency is controlled by a crystal oscillator and the divided ratio of the programmable divider. IC1 and IC2 are dual PLL ICs that control both VCO circuits for VHF and UHF. 4-3-2 VHF LOOP (VCO BOARD AND MAIN UNIT) The generated signal at the V-VCO (Q3, D1, D2) enters the PLL IC (MAIN unit; IC1, pin 8) via buffer-amplifiers (Q6, Q8) and VCO switching circuit (D50) 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 15 (MAIN unit). The pulse-type signal is converted into DC voltage (lock voltage) at the loop filter (MAIN unit; IC5, Q9, Q10, D4), and then applied to the V-VCO to stabilise the oscillated frequency. 4-2-9 UHF APC CIRCUIT (MAIN UNIT) The SWR detector circuit (D28, D34, L30) detects forward signals and reflection signals at D28 and D34 respectively. The combined voltage is at a minimum level when the antenna impedance is matched at 50 and is increased when it is mismatched. The detected voltage is applied to the APC amplifier (IC15, pin 3) and compared with a reference voltage which is supplied from the CPU (IC505) as a "PCON_U" D/A control signal. · VHF PLL CIRCUIT VCO switch Q5 Buffer VHF VCO Q4 Buffer Q3, D1, D2 Loop filter VCO switch Buffer D51 Q50 D5 to the transmitter circuit to the 1st mixer circuit D6 IC1 MB15A02PFV1 16 15 Phase detector Programmable counter Prescaler 8 9 PLLCK 10 PLLDATA 11 PLLSTB1 Q2 X2 15. 2 MHz Buffer 1 Programmable divider Shift register Buffer Q7 45. 6 MHz 2nd LO signal to the FM IF IC (IC8, pin 3) 4-6 4-3-3 UHF LOOP (VCO BOARD AND MAIN UNIT) The generated signal at the U-VCO (Q101, D100, D101) enters the PLL IC (MAIN unit; IC2, pin 8) via buffer-amplifiers (Q102, Q50) and VCO switching circuit (D51) 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 15 (MAIN unit). The pulse-type signal is converted into DC voltage (lock voltage) at the loop filter (MAIN unit; IC7, Q11, Q12, D5), and then applied to the U-VCO to stabilise the oscillated frequency. · WHILE RECEIVING UHF BAND OR 800 MHz BAND The oscillated signal at the U-VCO circuit is amplified at the buffer amplifiers (Q102, Q103), and is then applied to the VCO switching circuit (for UHF band; D104, for 800 MHz; D105). While receiving UHF band, the signal passes through the attenuator (C125, R117, R119, R120) and low-pass filter (Q105, L7, L8, C36­C38), and is then applied to the VCO switching circuit (D106). While receiving 800 MHz band, the signal is doubled at the doubler amplifier (Q104), and passes through the bandpass filter (L108­L110, C127, C129, C132, C133, C135) and attenuator (R127, R128). The back light has 3 colors (Umber, Green and Yellow). 5V 5VS VCO8 Common 8 V line which is selected by the SEL_SW circuit (Q6, Q8). The voltage is applied V_VCO8 to the VHF VCO (VCO board; Q3, D1, D2) and buffer amplifiers (VCO board; Q4, Q5). The voltage is applied U_VCO8 to the UHF VCO (VCO board; Q101, D100, D101) and buffer amplifiers (VCO board; Q102, Q103). Receive 5 V line converted from the 5VS line by the R5 regulator circuit (Q24). The circuit is controlled by the "R5CTRL" signal from the CPU (IC505, pin 78). Receive 5 V line for AM circuit converted from the 5VS line by the AM5 regulator circuit (Q25). The circuit is controlled by the "AM" signal from the CPU (IC505, pin 69). 4-5 POWER SUPPLY CIRCUITS 4-5-1 CONTROL UNIT VOLTAGE LINES Line Description Common 8 V converted from the HV line by the +8 regulator circuit (Q1, Q3, D5). The output voltage is applied to the LCD back light (DS22) and key back light (DS13­DS18, DS20, DS21, DS23) circuits. 8V R5 Common 5 V converted from the HV line by the CPU5V +5 regulator circuit (IC5, D4). The output voltage is applied to the reset circuit (IC2) and buffer amplifier (Q2). AM5 Receive 5 V line for VHF circuit converted from the 5VS line by the VHF_R5 regulator circuit VHF_R5 (Q26). The circuit is controlled by the "RXVHF" signal from the CPU (IC505, pin 73). Receive 5 V line for UHF circuit converted from the 5VS line by the UHF_R5 regulator circuit UHF_R5 (Q27).
