Circuit Discription 1. Receiver System 1-1. Front-end RF amplifier Incoming RF signal from the antenna is delivered to the Main Unit and passes through low-pass filter, antenna switching diode D1004 and D1005 (both 1SS390 ), high- pass filter and removed undesired frequencies by varactor tuned band-pass filter D1007 and D1009 (both 1SV325 ). The filtered RF signal is amplified by Q1015 ( BFS505 ) and then passes through another varactor tuned band-pass filter D1013 and D1014 (both 1SV325 ) to remove the undesired frequencies, and then applied to the 1st mixer Q1020 ( 3SK293 ). 1-2. First Mixer The RF signal is mixed with the 1st local signal be- tween 186.58 and 224.85 MHz in the 1st mixer Q1020 ( 3SK293 ), to produce 50.85 MHz 1st IF signal. The 1st local signal is generated by the VCO, which consists of Q1029 ( CPH3910 ), varactor diodes D1021, D1022, D1023, and D1025 (all 1SV282 ). The 1st lo- cal signal is supplied to the 1st mixer Q1020 ( 3SK293 ) through the buffer amplifier Q1021 and Q1026 (both 2SC5010 ). 1-3. IF Amplifier & Demodulator The 1st IF signal passes through monolithic crystal filters XF1001 (±7.5 kHz BW) to strip away all but the desired signal, and then supplied the buffer amplifier Q1035 ( 2SC5226 ). The amplified 1st IF signal is applied to the FM IF subsys- tem IC Q1040 ( AA32416 ) which contains the 2nd mixer, 2nd local oscillator, limiter amplifier, noise amplifier, and RSSI amplifier. The signal from reference oscillator X1002 (16.8 MHz) becomes three times of frequencies in Q1040 ( AA32416 ), it is mixed with the 1st IF signal and becomes 450 kHz. The 2nd IF signal passes through the ceramic filter CF1001 ( LTM450GW ) or CF1002 ( LTM450EW ) to strip away unwanted mixer products, and is supplied to the limiter amplifier in Q1040 ( AA32416 ), which removes amplitude variations in the 450 kHz IF, before detection of the speech by the ceramic discriminator CD1001 ( JT- BM450CX24 ). 1-4. Audio amplifier The detected signal from Q1040 ( AA32416 ) is supplied to the receiver circuit section of the Custom Baseband IC Q1018 ( FQ0801 ). The processed audio signal from Q1018 ( FQ0801 ) is supplied to the AF volume (VR1001) through the audio amplifier Q1008 ( TDA2822L ). As a result, the audio sig- nal provides up to 700 mW (@16-ohm BTL) for internal speaker or up to 500 mW (@4-ohm OTL) for external speaker. 1-5. Squelch Circuit There are 16 levels of squelch setting from “0” to “15”. The level “0” means open the squelch. The level “1” means the threshold setting level and level “14” means tight squelch. From level “2” to level “13” is established in the middle of threshold and tight. The level “15” be- comes setting of carrier squelch. 1-5-1. Noise Squelch The noise squelch circuit is consisted of the band-path fil- ter, noise amplifier Q1047 ( 2SC4617 ), and noise detector D1035 and D1036 (both DA221 ). When a carrier isn’t received, the noise ingredient which goes out of the demodulator section of Q1040 ( AA32416 ) is amplified by noise amplifier Q1047 ( 2SC4617 ) through the band-path filter, and then is detected to DC voltage by D1035 and D1036 (both DA221 ). The DC voltage is inputted to pin 54 (A/D port) of the CPU Q1028 ( RSF100LHDFB ). When a carrier is received, the DC voltage becomes low because the noise is compressed. When the detected voltage to CPU is “High”, the CPU stops the AF output of Q1013 ( DTC144EE ) by making to “low” of the pin 39 of CPU. When the detection voltage to CPU is “low”, the CPU al- lows the AF output of Q1013 ( DTC144EE ) by making to “High” of the pin 39 of CPU. 1-5-2. Carrier Squelch The detected RSSI voltage from pin 12 of Q1040 ( AA32416 ) supplied to pin 53 (A/D port) of Q1028 ( RS- F100LHDFB ). It is controls the AF output. The RSSI output voltage changes according to the signal strength of carrier. The stronger signal makes the RSSI voltage to be higher voltage. The process of the AF signal control is same as Noise Squelch. The shipping data is ad- justed 3 dBμ (EMF) higher than squelch tight sensitivity. FCC ID: AXI11273020 IC: 10239A-11273020 Vertex Standard LMR, Inc. 2. Transmitter System 2-1. MIC Amplifier The speech signal from internal microphone MC1001 or external microphone J1003 is supplied to the transmit- ter circuit section of the Custom Baseband IC Q1018 ( FQ0801 ) which is consist of the microphone amplifier, compander, pre-emphasis, limiter and splatter filter. The processed speech signal from pin 42 of Q1018 ( FQ0801 ) is amplified by Q1052-2 ( NJM12904R ), and then is made FM modulation to transmit carrier by the modulator D1019 ( BB208 ) of VCO Q1037 ( 2SC4227 ). 2-2. Drive and Final Amplifier Stages The modulated signal from the VCO Q1037 ( 2SC4227 ) is buffered by Q1026 ( 2SC5010 ). Then the signal is buffered by Q1021 ( 2SC5010 ) and Q1019 ( 2SK3077 ) for the driver amplifier Q1016 ( RQA0004PXDQS ). The low-level transmit signal is then applied to Q1012 ( RQA- 0011DNS ) for final amplification up to 5 watts output power. The transmit signal then passes through the antenna switch D1003 ( RN142S ) and is low-pass filtered to sup- press away harmonic spurious radiation before delivery to the antenna. 2-3. Automatic Transmit Power Control The current detector Q1053-1 ( NJM12902V ) detects the current of the driver amplifier Q1016 ( RQA0004PXDQS ) and final amplifier Q1012 ( RQA0011DNS ), and converts the current difference to the voltage difference. The output from the current detector Q1053-1 ( NJM12902V ) is compared with the reference voltage by Q1053-2 ( NJM12902V ). The output from Q1053- 2 ( NJM12902V ) controls the gate bias of the buffer amplifier Q1019 ( 2SK3077 ), driver amplifier Q1016 ( RQA0004PXDQS ), and final amplifier Q1012 ( RQA- 0011DNS ). The reference voltage changes into two levels (Transmit Power “High” and “Low”) controlled by Custom Base- band IC Q1018 ( FQ0801 ). 3. PLL Frequency Synthesizer 3-1.

VX-264 VHF Service Manual10 Introduction The VX-264 is carefully aligned at the factory for the specified performance across the frequency range speci- fied for each version. Realignment should therefore not be necessary except in the event of a component failure, or altering version type. All component replacement and service should be performed only by an authorized Vertex Standard representative, or the warranty policy may be void. 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 subsequently are replaced, realign- ment 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 com- ponent has been replaced. We recommend that servicing be performed only by au- thorized Vertex Standard service technicians who are ex- perienced 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 reserves the right to change circuits and alignment pro- cedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempt- ed unless the normal function and operation of the trans- ceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and realignment determined to be absolutely necessary. The following test equipment (and thorough familiarity with its correct use) is necessary for complete realign- ment. 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 adjust- ments 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. Required Test Equipment  RF Signal Generator with calibrated output level at 200 MHz  Oscilloscope  Deviation Meter (linear detector)  In-line Wattmeter with 5 % accuracy at 200 MHz  50 Ohm RF Dummy Load with power rating 10 W at 200 MHz  Regulated DC Power Supply (standard 7.5 V DC, 3 A)  Frequency Counter with 0.2 ppm accuracy at 200 MHz  Audio Signal Generator  AC Voltmeter  DC Voltmeter  UHF Sampling Coupler  IBM ® PC/compatible Computer with Microsoft ® Win- dows ® 2000, XP, Vista or Windows7  Vertex Standard CE150 PC Programming Software  Vertex Standard FIF-12 USB Programming Interface and CT-104A, CT-106, or CT-171 PC Programming Cable.  Vertex Standard FRB-6 Tuning Interface Box and CT- 160 Connection Cable.  Vertex Standard CN-3 (P/N: A08760001) Antenna Connector Alignment Preparation & Precautions A 50-Ohm RF Dummy Load and in-line wattmeter must be connected to the main antenna jack in all procedures that call for transmission, except where specified other- wise. Correct alignment is not possible with an antenna. Because of the BTL (Bridged Trans Less) Amplifier cir- cuit used in the VX-264, do not connect earth side of the speaker leads to chassis “ground”. After completing one step, read the following step to de- termine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, if connected) before proceeding. Correct alignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 68 and 86 °F (20 ~ 30 °C). When the transceiver is brought into the shop from hot or cold air, it should be allowed time to come to room temperature before alignment. Whenever possible, alignments should be made with os- cillator shields and circuit boards firmly affixed in place. Also, the test equipment must be thoroughly warmed up before beginning. Note: Signal levels in dB referred to in the alignment pro- cedure are based on 0 dBμ EMF = 1 μV. Alignment FCC ID: AXI11273020 IC: 10239A-11273020 Vertex Standard LMR, Inc. VX-264 VHF Service Manual11 Test Setup Setup the test equipment as shown below for transceiver alignment, then apply 7.5 V DC power to the transceiver. The Alignment Tool Outline Installation of the alignment tool  Install the CE150 (PC Programming Software) to your PC.  “Alignment“ function in the “Radio“ menu tab of CE150. Action of the switches When the transceiver is in the “Alignment mode,“ the ac- tion of the Front Panels Programmable key ([ A ] / [ B ] / [ C ] / [ D ]) , SIDE-1 , SIDE-2 , and PTT keys are ignored. All of the action is controlled by the PC. Caution Please never turn off the power supply during alignment. If the power supply is turned off during alignment, the alignment data will be corrupted. Alignment Alignment Mode In the “Alignment Mode”, the aligned data written in the radio will be able to re-align its alignment data. The value of each parameter can be changed to desired position by “ ‘ ”/“ ’ ” arrow key for data up/down, “ “ ”/“ ” ” arrow key for channel up/down, direct number input, and drag the mouse. Note: when all items are aligned, it is strongly recom- mended to align according to following order. The detail information is written in the help document of CE150 PC Programm…
