FCC ID: K66VX-4204-0H Circuit Description 1/3 Vertex Standard Co., Ltd. VX-4204 Circuit Description 1. Circuit Configuration by Frequency The receiver is a double-conversion superheterodyne with a first intermediate frequency (IF) of 50.85MHz and a second IF of 450kHz. Incoming signal from the antenna is mixed with the local signal from the VCO/PLL to produce the first IF of 50.85MHz. This is then mixed with the 50.4MHz second local oscillator output to produce the 450kHz second IF. This is detected to give the demodulated signal. The transmit signal frequency is generated by the PLL VCO, and modulated by the signal from the microphone. It is then amplified and sent to the antenna. 2. Receiver System 2-1. Front-end RF amplifier Incoming FR signal from the antenna is delivered to the RF Unit and passes through Low-pass filer, antenna switching diode, and removed undesired frequencies by varactor diode (tuned band-pass filer: T1001, T1002 and T1003). The passed signal is amplified in Q1022 and moreover cuts an image frequency with the band path filter and comes into the 1st mixer. The Q1020 controls bias of Q1022. 2-2. First Mixer The 1st mixer consists of the Q1035, T1004, T1005 and T1006. Buffered output from the VCO is amplified by Q1038 to provide a pure first local signal between 184.85 and 224.85MHz for injection to the first mixer. The output IF signal is amplified by Q1046 and enters from the mixer to the crystal filter. The IF signal then passes through monolithic crystal filters XF1001 (±5.5 kHz BW) to strip away all but the desired signal. 2-3. IF Amplifier The first IF signal is amplified by Q1059. The amplified first IF signal is applied to FM IF subsystem IC Q1079 which contains the second mixer, second local oscillator, limiter amplifier, noise amplifier, and S-meter amplifier. The signal from reference oscillator X1003 becomes 3 times of frequencies in Q1079, it is mixed with the IF signal and becomes 450KHz. The second IF then passes through the ceramic filter CF1001 (for wide channels), CF1002 (for narrow channels) to strip away unwanted mixer products, and is applied to the limiter amplifier in Q1038, which removes amplitude variations in the 450kHz IF, before detection of the speech by the ceramic discriminator CD1001. 2-4. Audio amplifier Detected signal from Q1079 is inputted to Q1037 and is output through the band path filter inside Q1037. In the case an optional unit is installed, the Q1063 is made OFF and the AF signal from Q1037 goes the optional unit. In the case an optional unit is not installed, Q1037 is made ON and the signal goes through Q1063. The signal then goes through AF mute switch Q1068, de-emphasis part and expander Q1021. When the function of expander is off, the 1021 will be bypassed by Q1069. The output signal of expander (or a signal from de-emphasis) is amplified by Q1088 and it is amplified with AF power amplifier Q1005 after passing AF volume Q1029. The output of Q1005 drives a speaker (it chooses the external SP or internal SP in J6001) 2-5. Squelch Circuit There are 13 levels of squelch setting from 0 to 12. The level 0 means open the squelch. The level 1 means the threshold setting level and level 11 means tight squelch. FCC ID: K66VX-4204-0H Circuit Description 2/3 Vertex Standard Co., Ltd. From 2 to 10 is established in the middle of threshold and tight. The bigger figure is nearer the tight setting. The level 12 becomes setting of carrier squelch. 2-5-1. Noise Squelch Noise squelch circuit is composed of the band path filter of Q1079, noise amplifier Q1091, and noise detector D1059, D1061. When a carrier isn't received, the noise ingredient which goes out of the demodulator Q1079 is amplified in Q1091 through the band path filter Q1079, is detected to DC voltage with D1059, D1061 and is inputted to 19pin (the A/D port) of the Q1083 (CPU). 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 AF output with Q1068 "OFF" by making the 40pin "L" level. When the detection voltage is low, the CPU makes Q1068 ON with making 40pin "H" and the AF signal is output. 2-5-2. Carrier Squelch The CPU (18pin: A/D port) detect RSSI voltage output from Q1079 12 pin, and controls 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 adjusted 3dB higher than squelch tight sensitivity. 3. Transmitter System 3-1. Mic Amplifier The AF signal from microphone jack J4001 (4ch) or J5001 (501ch) is amplified with microphone amplifier Q1066, is amplified with 2nd microphone amplifier Q1088 after microphone selection switch Q1016, and passes microphone gain volume Q1029. The AF signal which was controlled in the correct gain passes compandor Q1021. When not using a compandor, with the control from the CPU, it passes in the compandor circuit inside of Q1021 and it is output and it passes a pre-emphasis circuit. Q1063 becomes OFF when an option unit is attached and the AF signal from Q1037 goes via the option unit. When an option unit isn't attached, Q1063 becomes ON, the signal passes Q1063 and is input to Q1037. The signal passed limiter and splatter filer of Q1037 is adjusted by maximum deviation adjustment volume Q1029. The adjusted low frequency signal ingredient is amplified by Q1074, added modulation terminal of TCXO (X1003), the FM modulation is made by reference oscillator. The high frequency signal ingredient is amplified Q1074, and adjusted the level by volume Q1029 to make frequency balance between low frequency. After that, it is made FM modulation to transmit carrier by the modulator D1030 of VCO. 3-2. Drive and Final amplifier The modulated signal from the VCO Q1054 is buffered by Q1049 and amplified by Q1038 and Q1002. The low-level transmit signal is then applied to the Power Module Q10…

FCC ID: K66VX-4204-0H Alignment 1/6 Vertex Standard Co., Ltd. VX-4204 Alignment Introduction The VX-4204 is carefully aligned at the factory for the specified performance across the frequency range specified 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 placed, 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 reserves 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 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. Required Test Equipment ˆ RF Signal Generator with calibrated output level at 200MHz ˆ Deviation Meter (linear detector) ˆ In-line Wattmeter with 5% accuracy at 200MHz ˆ 50Ω RF Dummy Load with power rating 100W at 200MHz ˆ 8Ω/10W AF Dummy Load (Attention : Audio output is BTL output) ˆ Regulated DC Power Supply (standard 13.6V DC, 15A) ˆ Frequency Counter with 0.2ppm accuracy at 200MHz ˆ AC Voltmeter ˆ DC Voltmeter ˆ VHF Sampling Coupler ˆ IBM PC / compatible Computer with Microsoft DOS v3.0 or later operating system ˆ Vertex Standard VPL-1 Connection Cable & Alignment program FCC ID: K66VX-4204-0H Alignment 2/6 Vertex Standard Co., Ltd. Alignment Preparation & Precautions A 50-Ω 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 otherwise. Correct alignment is not possible with an antenna. After completing one step, read the following step to determine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, in 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 20 and 30°C (68 - 86 °F). 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 oscillator 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 procedure are based on 0dBμ EMF = 1μV. Setup the test equipment as shown for transceiver alignment, apply 13.6V DC power to the transceiver. Refer to the drawings above for Alignment Points.
