11. CIRCUIT EXPLANATION RX ANTENNA CHANGEOVER CIRCUIT ANTENNA CHANGEOVER CIRCUIT'S FUNCTION IS A LOW-PASS FILTER IN RECEIVING, TUNING CIRCUIT IN TRANSMITTING. CIRCUIT PROTECTS TRANSMITTING SIGNALS FROM BEING INPUT TO RECEIVING CIRCUIT. RECEIVING SIGNAL IS INPUT TO MAIN UNIT THROUGH ANTENNA CONNECTOR & LOW-PASS FILTER (L12, L13, C102-C104, C97). INPUT SIGNAL IS APPLIED TO RF CIRCUIT VIA THE NEXT ANTENNA CHANGEOVER CIRCUIT. (D7, L9, C72.
THE 2ND MIDDLE FREQUENCY & DEMODULATOR CIRCUIT THE 2ND MIXED CIRCUIT TRANSLATES THE 1-IF SIGNAL TO THE 2-IF SIGNAL. DOUBLE SUPER HETERODYNE METHOD (TRANSLATE RECEIVING SIGNAL TWICE) IMPROVES IMAGE REJECTION RATIO & GAINS STABLE RECEIVING PROFITS. FM IF IC (U2) INCLUDES THE 2ND PART OSCILLATOR, THE 2ND MIXER, LIMITER AMPLIFIER, QUADRATURE DEMODULATOR AND NOISE DETECTOR CIRCUIT, ETC. THE 1-1F SIGNAL FROM Q6 IS APPLIED TO THE 2ND MIXER OF U2 (PIN 16). AND THE 2ND LO SIGNAL OF 21.
AMPLIFIES & FILTERS NOISE COMPONENT. FILTERED SIGNAL IS APPLIED TO NOISE DETECTER & "NREC" SIGNAL IS OUTPUT FROM PIN 14. "NREC" SIGNAL IS AMPLIFIED BY DC AMPLIFIER (U10/B) OF CPU BOARD & APPLIED AS "SQL0" BY CPU (U8, PIN 80). CPU ANALYZE NOISE STATUS AND OUTPUT "RMUTM", "RMUTS" SIGNALS TO CHANGE AF MUTE SWITCH(U12/A, U12/B).
APC (AUTOMATIC POWER CONTROL) CIRCUIT APC CIRCUIT STABILIZES Tx OUTPUT POWER. RF OUTPUT SIGNAL FROM POWER AMPLIFIER (U8) IS DETECTED TO OUTPUT DETECTING CIRCUIT (D13, D14). THEN, IT IS APPLIED TO ONE OF DIFFEENTIAL MOTION AMPLIFIER (Q22) INPUTS VIA High/Low CONTROL CIRCUIT (VR2, Q23). APPLIED POWER CONTROLS DIFFEENTIAL MOTION AMPLIFIER (Q22) OUTPUT & BIAS VOLTAGE CONTROL (Q17). LIKE THIS, APC CIRCUITS KEEPS CERTAIN OUTPUT POWER.
VCO (VOLTAGE CONTROL OSCILLATER) CIRCUIT OUTPUT FROM VCO (Q16) IS AMPLIFIED AT BUFFER AMPLIFIER (Q15). THEN IT IS SENT TO Tx/Rx SWITCHED (D8, D6). Rx LO SIGNAL IS APPLIED TO THE 1ST MIXER CIRCUIT (Q5) THROUGH LOW PASS FILTER, AND Tx SIGNAL IS APPLIED TO PRE-DRIVE AMPLIFIER (Q19). A PART OF VCO OUTPUT IS USED AGAIN AT PLL IC (U5, PIN 6) VIA C146. DSC (DIGITAL SELECTIVE CALLING) MODULATING CIRCUIT MODULATING SIGNAL FROM CPU IS DELIVERED THROUGH LOW PASS FILTER (U14/B) WITH + 6 dB/OCTAVE FEATURE.
- CHECK THE SOLDERING OF OUTER SPEAKER CABLES. - CHANGE SPEKAER IC U6(LA4425) OF V-896. > BUTTON SOUND DEFECTS - CHANGE R51 OF V-891 - C1 OF V-896 IS SLIGHTLY BROKEN - RESOLDER U6 OF Y-896 TX, RX DEFECTS - WHEN TX IS ALWAYS AT LOW(LO) POWER, EVEN IF HIGH(HI) POWER IS SELECTED - CHECK ANTENNA & ANTENNA CABLE. IF ANTENNA & ANTENNA CABLE HAVE DEFECTS, ALARM SOUNDS & Tx OUTPUT IS AUTOMATICALLY CHANGED TO 1W. SO, CHECK ANTENNA & ANTENNA CABLE. Tx OUTPUT DEFECTS (IT BECOMES RESET, IF KEY IS CAUGHT.
