FCC ID: K66VX-5500L Circuit Description 1/3 Vertex Standard Co., Ltd. VX-5500L Circuit Description Reception and transmission are switched by “ RX ” and ” TX ” lines from the microprocessor unit (MPU). The receiver uses double-conversion super-heterodyne circuitry, with a 17.7MHz 1st IF and 450 kHz 2nd IF. The 1st LO, produced by a PLL synthesizer, yields the 17.7MHz 1st IF. The 2nd LO uses a 17.25 MHz (17.7 MHz-450 kHz) signal generated by a crystal oscillator. The 2nd mixer and other circuits use a custom IC to convert and amplify the 2nd IF, and detect FM to obtain demodulated signals. During transmit, the PLL synthesizer oscillates at the desired frequency directly, for amplification to obtain RF power output. During transmit, voice modulation and CTCSS (or DCS) modulation are applied to this synthesizer. Transceiver functions, such as Tx/Rx control, PLL synthesizer settings, and channel programming, are controlled using the MPU. Receiver Incoming RF signals from the antenna connector are delivered to the MAIN Unit, and pass through a low-pass filter (LPF) antenna switching network consisting of coils L1011, L1012, L1014, and L1009 , capacitors C1017, C1024, C1029, C1030, C1034 and C1002, and antenna switching diodes D1032 and D1001 for delivery to the receiver front end. Signals within the frequency range of the transceiver are then passed through a varactor-tuned band-pass filter consisting of T1001, T1002 before RF amplification by Q1006. The amplified RF is then band-pass filtered again by varactor-tuned resonators T1003, T1004 to ensure pure in-band input to 1st mixer Q1040. Buffered output from the VCO Unit is amplified by Q1027 and low-pass filtered by L1023 / L1020 and C1161 / C1152 / C1143, to provide a pure 1st local signal between 54.7 and 67.7 MHz to the 1st mixer. The 17.7MHz 1st mixer product then passes through dual monolithic crystal filters XF1001 and XF1002 (12 kHz BW) is amplified by Q1035 and delivered to the input of the FM IF subsystem IC Q1034. This IC contains the 2nd mixer, 2nd local oscillator, limiter amplifier, FM detector, noise amplifier, and squelch gates. The 2nd LO in the IF-IC is produced from crystal OSC amp X1001,Q1033 (17.25MHz), and the 1st IF is converted to 450kHz by the 2nd mixer and stripped of unwanted components by ceramic filter CF1001 . After passing through a limiter amplifier, the signal is demodulated by the FM detector. Demodulated receive audio from the IF-IC is amplified by Q2019. After volume adjustment by the AF power amplifier Q2018, the audio signal is passed to the optional headphone jack or 4 Ω loudspeaker. FCC ID: K66VX-5500L Circuit Description 2/3 Vertex Standard Co., Ltd. PLL synthesizer The 1st LO maintains stability from the PLL synthesizer by using a 17.7 MHz reference signal from crystal OSC amp X1001,Q1033. PLL synthesizer IC Q1029 consists of a prescaler, reference counter, swallow counter, programmable counter, a serial data input port to set these counters based on the external data, a phase comparator, and charge pump. The PLL-IC divides the 17.700 MHz reference signal by 885 using the reference counter (20.0 kHz comparison frequency). The phase detector comparison frequency to be eight times the channel spacing (5kHz). The VCO output is divided by the prescaler, swallow counter and programmable counter. These two signals are compared by the phase comparator and input to the charge pump. A voltage proportional to their phase difference is delivered to the low-pass filter circuit, then fed back to the VCO as a voltage with phase error, controlling and stabilizing the oscillating frequency. This synthesizer also operates as a modulator during transmit. The RX-VCO is comprised two oscillator. The one is comprised of Q1015 and D1016, D1017, and oscillates between 54.7MHz and 61.199MHz. The another is comprised of Q1042 and D1038, D1039 and oscillated between 61.2MHz and 67.7MHz. The each VCO is programmed according to receiving frequency. And the TX-VCO is comprised of Q1016 and D1012, D1013, D1014,D1015 and oscillates between 37.0MHz and 50.0MHz according to the programmed transmit frequency. The VCO output passes through buffer amplifier Q1021, and a portion is fed to the buffer amplifier Q1023 of the PLL IC, and at the same time amplified by Q1027 to obtain stable output. The VCO DC supply is regulated by Q1007. Synthesizer output is fed to the 1st mixer by diode switch D1022 during receive, and to drive amplifier Q1004 for transmit. Transmitter Voice audio from the microphone is delivered via the MIC (Jack) Unit to the MAIN Unit, after passing through amplifier Q3039/Q2041, pre-emphasis, limiter (IDC instantaneous deviation control), and LPF Q2001, is adjusted for optimum deviation level and delivered to the next stage. Voice input from the microphone and CTCSS are FM-modulated to the VCO of the synthesizer, while DCS audio is modulated by the reference frequency oscillator of the synthesizer. Synthesizer output, after passing through diode switch D1022, is amplified by driver Q1004 / Q1002 and power amp Q1001 to obtain full RF output. The RF energy then passes through antenna switch D1033, D1034 and a low-pass filter circuit and finally to the antenna connector. RF output power from the final amplifier is sampled by CM coupler and is rectified by D1036, D1037. The resulting DC is fed through Automatic Power Controller Q1038 to transmitter RF amplifier and thus the power output. Generation of spurious products by the transmitter is minimized by the fundamental carrier frequency being equal to the final transmitting frequency, modulated directly in the transmit VCO. Additional harmonic suppression is provided by a low-pass filter consisting of L1017 L1012, L1011 and C1102, C1098, C1088,C1034,C1030,C1029 and C1024, resulting in more than 60 dB of harmonic suppression prior to delivery to the RF energy to the antenna. DCS Demodulator DCS signals are demodulated on the MAIN-UNIT, and are applied to low-pass filter Q20…

FCC ID: K66VX-5500L Alignment 1/4 Vertex Standard Co., Ltd. VX-5500L Alignment The VX-5500 has been 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 alteration of version. All component replacement and service should be performed only by an authorized VERTEX STANDSRD 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. Required Test Equipment RF signal generator: calibrated output level at 1000 MHz (0 dBμ =1.0 μV - closed circuit) Deviation Meter (linear detector) AF Millivoltmeter SINAD Meter Inline Wattmeter with 5% accuracy at 1000 MHz Regulated DC Power Supply: adjustable from 10 to 17 VDC, 15A 50 Ω Non-reactive Dummy Load: 100W at 1000 MHz Frequency Counter: >0.1-ppm accuracy at 1000 MHz AF Signal Generator DC Voltmeter: high impedance RF Sampling Coupler (attenuation pad) AF Dummy Load: 4 Ω , 20W Oscilloscope Spectrum Analyzer IBM PC/compatible computer w/ VERTEX STANDARD CT-71 programming cable and CE-49 channel programming editor. FCC ID: K66VX-5500L Alignment 2/4 Vertex Standard Co., Ltd. 50-Ω RF Signal Dummy load Generator RF Sampling Inline Wattmater Coupler Transceiver Deviation Meter CT-71 CT-29 Connection Frequeuncy Cable Power Supply Counter IBM PC 13.8V DC COM port Alignment Preparation & Precautions A dummy load and inline 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, 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 20 and 30 °C (68 and 86 °F). When the transceiver is brought into the shop from hot or cold air it should be allowed some time for thermal equalization with the environment before alignment. If 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. Before beginning, connect the transceiver and PC using the CT-71 programming cable as described in the EEPROM Programming chapter, and downloads the EEPROM data from the transceiver to the computer. Store this data in a disk file so that it can be saved and retrieved later. Using the table below, program the channel, CTCSS, and DCS alignment settings for your transceiver version. Upload this file to the transceiver. Note: Signal levels in dB referred to in this procedure are based on 0 dBm = 0.5 μV (closed circuit). Caution: Do not connect this line to ground, and be certain that the speaker has adequate capability to handle the audio output from the radio. Because of the bridge audio amplifier circuit used in the radio, it is necessary to construct and use a simple audio load test adapter as shown in the schematic diagram above, when conducting receiver alignment steps. 3.5 φ PLUG Attenuated Test Output (1/2) 2 Ω  10 W Ground + 470 μF 2 Ω 10 W AF Test Adapter Schematic FCC ID: K66VX-5500L Alignment 3/4 Vertex Standard Co., Ltd.
