FCC ID: K6610443250 IC ID: 511B-10443250 Circuit Description 1/3 Vertex Standard Co., Ltd. VXR-9000V-H Circuit Description Receive Signal Path Incoming RF from the RX antenna jack is delivered to the MAIN Unit and passes through the protection diode D1001 and D1002 and a varactor-tuned band pass filter consisting of coils L1044 and L1048, capacitors C1400, C1402, C1403, C1407, C1408, C1409 and C1410, and varactor diodes D1033 and D1034. Signals are then applied to the RF amplifier, Q1063. The amplified RF signal is applied through a varactor-tuned band pass filter consisting of coils L1050 and L1051, capacitors C1427, C1429, C1430, C1431, C1433, C1434, C1435 and C1436, and varactor diode D1035 and D1036 to the 1 st mixer Q1018 along with the first local signal from the PLL circuit. The first local signal is generated between 221.35 and 234.3475 MHz by the RX VCO, which consists of FET Q1048 and varactor diodes D1018, D1019, D1020 and D1021 according to the programmed receiving frequency; the local signal then passes through buffer amplifier Q1059 and first local amplifier Q1019 to the first mixer Q1018. The first local signal is generated between 234.35 and 247.35 MHz by the RX VCO, which consists of FET Q1053 and varactor diodes D1027, D1028, D1029 and D1030 according to the programmed receiving frequency; the local signal then passes through buffer amplifier Q1059 and first local amplifier Q1019 to the first mixer Q1018. The 73.35 MHz first IF signal is applied to monolithic crystal filters XF1001/XF1002 (Wide) or XF1501/XF1502 (Narrow) which strip away unwanted mixer products, and the IF signal is applied to the first IF amplifiers Q1022 (Wide) / Q1502 (Narrow). The amplified first IF signal is then delivered to the FM IF subsystem IC Q1028, which contains the second mixer, second local oscillator, limiter amplifier, noise amplifier, and FM detector. A 2nd local oscillator signal, generated by the 72.895 MHz crystal X1002, produces the 455 kHz second IF signal when mixed with the first IF signal within Q1028. The second IF signal passes through ceramic filter CF1001 or CF1002 which strips away all but the desired signal, and then passes through the limiter amplifier within Q1028 to ceramic discriminator CD1001, which removes any amplitude variations in the 455 kHz IF signal before detection of speech. The detected audio passes through the low pass filter, consisting of R1199 and C1244, which rejects the 455 kHz IF component. The audio signal from the MAIN Unit is delivered to the CNTL Unit and passes through the audio amplifier Q1020 to the active high pass filter section of Q3020, which rejects the sub-audible frequency component. The filtered audio signal is delivered to electronic volume Q1056, which adjusts the audio sensitivity to compensate for audio level variations, then passes through audio amplifier Q1020, audio switch Q1040, attenuator consisting of R1233, and limiter amplifier Q1050, to the electronic volume control Q1056, where the maximum deviation is set. The audio signal subsequently passes through the 3-section active low pass filter consisting of Q1017-1/-2/-3 and audio amplifier Q1001 to providing the repeater transmit audio. A portion of the audio signal from the active high pass filter section of Q3020 is de-emphasized by R3095 and C3080, providing a flat audio response. The filtered audio then passes through the active band pass filter Q3021 and audio mute gate Q3015 to audio power amplifier Q1057, providing up to 2 Watts of audio power to the 8 Ω loudspeaker. Sub-Audible Signaling (DECODER) A portion of the audio signal from the audio amplifier Q1020 passes through the 3-section active low pass filter Q1025 and the low pass filtering section of Q3020 to separate the CTCSS tones from the received audio signal. The CTCSS tones are sent to the CTCSS decoder section of Q3020. When a CTCSS tone is received, the CTCSS information is delivered to pin 77 of Main CPU Q3014 from pin 4 and 8 of Q3020 which compares the FCC ID: K6610443250 IC ID: 511B-10443250 Circuit Description 2/3 Vertex Standard Co., Ltd. CTCSS tone with the programmed tone. Another portion of the audio signal amplified by Q1020 passes through the 3-section active low pass filter Q3044 to separate the DCS codes from the received audio signal. The low pass filtered signal passes through the phase detector Q3044 to pin 39 of Main CPU Q3014. When a DCS code is received, the Main CPU Q3014 compares the DCS code with the programmed code. If the received CTCSS tone or DCS code matches the programmed tone or code, pin 4 of the Main CPU Q3014 goes low, turning off the squelch switch Q3015 and passing the received audio signal to the audio power amplifier Q1057. Squelch Control The squelch circuit consists of noise amplifier Q1033 and noise detector D1015 on the MAIN Unit, and control circuitry within Main CPU Q3014 on the CNTL Unit. When no carrier is received, noise at the output of the audio detector stage of Q1028 is amplified by Q1033, and then rectified by D1015 to provide a DC control voltage for the squelch switch. The resulting DC voltage is delivered to pin 23 of J1005. The DC voltage from the MAIN Unit is delivered to the A-D analog input port (pin 51) of the Main CPU Q3014 on the CNTL Unit, which compares the squelch threshold level to that which is memorized in EEPROM Q3006 or set by the front panel SQL control. RX PLL and VCO Circuits The receiver’s PLL circuitry consists of PLL subsystem IC Q1052 on the MAIN Unit, which contains a reference oscillator/divider, serial-to-parallel data latch, programmable divider, phase comparator and a swallow counter. Stability is obtained by a regulated 5 V DC supply via Q1062 and temperature compensated 14.4 MHz crystal oscillator X1003. The RX VCO made up two VCO circuit, one is Low-Band RX VCO, consisting of FET Q1048 and varactor diodes D1018, D1019, D1020 and D1021, and another one is High-Band RX VCO, consisting of FET Q1053 and varactor diodes D1027, D1028…

FCC ID: K6610443250 IC IF: 511B-10443250 Alignment 1/4 Vertex Standard Co., Ltd. VXR-9000V-H Alignment Introduction The VXR-9000-H has been aligned at the factory for the specified performance across the entire frequency range specified. Realignment should therefore not be necessary except in the event of a component failure. All component replacement and service should be performed only by an authorized Vertex Standard representative, or the warranty policy may be voided. The following procedures cover the sometimes critical and tedious adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts are replaced, realignment may be required. If a sudden problem occurs during normal operation, it is likely due to component failure; realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by authorized Vertex Standard service technicians who are experienced with the circuitry and fully equipped for repair and alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized Vertex Standard service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by unauthorized attempts at realignment are not covered by the warranty policy. Also, Vertex Standard must reserve the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the transceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and the need for realignment determined to be absolutely necessary. The following test equipment (and thorough familiarity with its correct use) is necessary for complete realignment. Correction of problems caused by misalignment resulting from use of improper test equipment is not covered under the warranty policy. While most steps do not require all of the equipment listed, the interactions of some adjustments may require that more complex adjustments be performed afterwards. Do not attempt to perform only a single step unless it is clearly isolated electrically from all other steps. Have all test equipment ready before beginning, and follow all of the steps in a section in the order presented. FCC ID: K6610443250 IC IF: 511B-10443250 Alignment 2/4 Vertex Standard Co., Ltd.
