Unit 5, 20/F., Seaview Centre, Hoi Bun Road, Kwun Tong, Kowloon, Hong Kong Introduction This manual provides technical information necessary for servicing the VXA-700 Transceiver. Servicing this equipment requires expertise in handling surface-mount chip components. Attempts by non-qualified persons to service this equipment may result in permanent damage not covered by the warranty, and may be illegal in some countries. Two PCB layout diagrams are provided for each doublesided circuit board in the transceiver. Each side of thr board is referred to by the type of the majority of components installed on that side ( leaded or chip-only ). In most cases one side has only chip components, and the other has either a mixture of both chip and leaded components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only. While we believe the technical information in this manual to be correct, Vertex Standard assumes no liability for damage that may occur as a result of typographical or other errors that may be present. Your cooperation in pointing out any inconsistencies in the technical information would be appreciated.

7 Circuit Description Receive Signal Path Narrow FM and AM mode Incoming RF from the antenna jack is passed through a low-pass filter and high-pass filter consisting of coils L1028, L1030, L1035, L1036, L1041, and L1045, capacitors C1142, C1145, C1147, C1153, C1155, C1159, C1164, C1167, C1180, C1182, C1185, and C1186 and antenna switching diodes D1016 (RLS135), D1017 (HSU275), and D1019 (RLS135), and then proceeds to the receiver front end section. Signals within the frequency range of the transceiver are applied to the receiver front end which contains RF amplifier Q1043 (2SC5555) and a varactor-tuned band-pass filter consisting of coils L1022, L1023, L1026, L1027, L1037, L1038, L1043, and L1044, capacitors C1130, C1134, C1135, C1140, C1143, C1157, C1168, C1175, C1176, C1179, and C1181, and diodes D1014, D1018, D1024, and D1026 (all HVC350), and then applied to the 1st mixer Q1040 (2SC5555). Buffered output from the VCO is amplified by Q1017 (2SC5555) to provide a pure 1st local signal between and MHz for injection to the 1st mixer. The 35.4 MHz 1st mixer product then passes through monolithic crystal filter XF1001 (35M15A1, 7.5 khz BW) which strips away unwanted mixer product;, the 1st IF signal is then amplified by mixer post-amp Q1033 (2SC4215Y). The amplified 1st IF signal is applied to the FM IF subsystem IC Q2039 (TA31136FN), which contains the 2nd mixer, 2nd local oscillator, limiter amplifier, noise amplifier and FM detector. The 2nd local signal is generated by PLL reference/2nd local oscillator Q2030 (2SC4116GR) from the MHz crystal X2001. The MHz signal is doubled by Q2036 (2SC4400) to produce the 450 khz 2nd IF when mixed with the 1st IF signal within Q2039. The 2nd IF signal then passes through the ceramic filter CF2002 (ALFYM450) and CF2003 (CFWM450D) to remove all but the desired signal. In the FM mode, the 2nd IF signal from ceramic filters CF2002 and CF2003 is applied to the limiter amplifier section of Q2039, which removes amplitude variations in the 450 khz IF before detection of the speech by the ceramic discriminator CD2001 (CDBM450C24). Detected audio from Q2039 is passed through the de-emphasis network, consisting of resistors R2051, R2053, R2054, and R2101, capacitors C2048, C2049, C2053, and C2077, and Q (NJM2904V), then applied to the AF amplifier Q2010 (TDA7233D). In the AM mode, the 2nd IF signal from ceramic filters CF2002 and CF2003 is amplifed by Q2039 and Q2043 (both 2SC4116GR), then amplifed signal is applied to the AM detecter D2028 (RB751S). Detected audio from D2028 is passed through the audio amplifier Q (NJM2904V) and ANL circuit, then applied to the AF amplifier Q (NJM2904V). When impulse noise is received, a portion of the AM detector output signal from D2028, including pulse noise, is rectified by D2012 (BAS316). The resulting DC is applied to the ANL MUTE gate Q1019 (UMG2N), which briefly interrupts the signal flow, thus reducing the level of the pulse noise. The processed audio signal from Q passes through the audio mute gate Q2014 (DTC143ZE) and the volume control to the audio power amplifier Q2010 (TDA7233D), providing up to 0.4 Watts to the headphone jack or 8 Ω loudspeaker. A portion of the AF signal from the FM IF subsystem Q2039 converted into DC voltage within the IC, and then passes through the AGC amplifier Q2026 (UMW1), Q2027 (2SA1602A), and Q2045 (TC75S51F) to the inversion amplifiers Q1035 and Q1042 (both 2SC5555). These amplifier reduce the amplifier gain of the IF amplifier Q1033 and the RF amplifier Q1043 when receiving a strong signal. Wide FM mode Incoming RF from the antenna jack is passed through a low-pass filter consisting of coils L1030, L1035, L1036, and L1042, capacitors C1142, C1145, C1147, C1153, C1155, C1159, and C1167, and antenna switching diodes D1016 (RLS135), D1017 (HSU275), and D1019 (RLS135), and then proceeds to the receiver front end section. The RF signal is applied to the wide FM receiver front end which contains RF amplifiers Q1041 (2SC5555) and Q1046 (2SC5555) and a varactor-tuned band-pass filter consisting of coils L1017, L1018, L1024, L1025, L1033, L1034, L1039, and L1040, capacitors C1125, C1128, C1129, C1131, C1136, C1148, C1158, C1162, C1163, and C1169, and diodes D1013, D1015, D1022, and D1025 (all HVC359), then applied to the 1st mixer Q1039 (2SC5555). Buffered output from the VCO is amplified by Q1017 (2SC5555) to provide a pure 1st local signal between and MHz for injection to the 1st mixer. The MHz 1st mixer product then passes through bandpass filter consisting of coils L1010 and L1011, and capacitors C1075, C1078, C1081, C1083, C1087, C1092, and C1093. The 1st IF signal is applied to the wide FM IF subsystem IC Q2023 (TA7792F), which contains the 2nd mixer, 2nd local oscillator, limiter amplifier and FM detector. The 2nd local signal is generated by PLL reference/2nd local oscillator Q2030 (2SC4116GR) from the MHz crystal X2001. The MHz signal is doubled by Q2036 (2SC4400) to produce the 10.7 MHz 2nd IF when mixed with the 1st IF signal within Q2023. The 2nd IF signal then passes through ceramic filter CF2001 (SFECV10.7MS2) to strip away unwanted mixer products. 7

8 Circuit Description The filtered 2nd IF signal from ceramic filter CF2001 is applied to the limiter amplifier section of Q2023, which removes amplitude variations in the 10.7 MHz IF before detection of the speech by the detector (which includes coil L2002 and capacitor C2061). Detected audio from Q2023 is passed through the de-emphasis network, consisting of resistors R2051, R2053, R2054, and R2074, capacitors C2048, C2049, C2050, and C2063, and Q (NJM2904V); the audio is then applied to the AF amplifier, Q2010 (TDA7233D). Squelch Control When a signal is received, a DC squelch control voltage appears at pin 12 of FM IF subsystem IC Q2039 at a level according to the received signal strength. This DC is applied to pin 13 of microprocessor Q3026 (LC87F52C8A). The DC squelch control voltage is compared with the SQL threshold level by the microprocessor, Q3026. If the DC squelch control voltage is higher, pin 46 of Q3026 goes high. This signal activates the AF MUTE gate Q2014 (DTC143ZE), thus disabling the receiver audio. If a signal strong enough to exceed the threshold level is received the microprocessor stops scanning, if scanning is engaged, and allows audio to pass through the AF MUTE gate Q2014. Transmit Signal Path Speech input from the microphone is passed through microphone amplifier Q (NJM2902V), then applied to the ALC amplifier Q3011 (AN5123MS). In the AM mode, the amplified speech signal is passed through the low-pass filter Q (NJM2902V) and high-pass filter Q (NJM2904V). The filtered speech signal is passed through Q3013 (M62364FP), which adjusts the modulation level, then fed to the AM modulator Q1037 (2SK2974). In the FM mode, the amplified speech signal is passed through the low-pass filter Q (NJM2902V) and high-pass filter Q (NJM2902V), where the signal is pre-emphasized and stripped of excessive high frequency components that might result in over-deviation. The processed audio may be mixed with a CTCSS tone generated by the microprocessor Q3026, and the level is controlled by Q3013 (M62364FP). The audio is then delivered to D1005 (HSU277) for frequency-modulation of the PLL carrier up to 5 khz from the un-modulated carrier at the transmitting frequency. When using the optional headset, the SIDETONE signal from J2001 becomes HIGH, turning pin 18 of Q3026 on; pin 56 of Q3026 then goes HIGH, routing a portion of the speech to the AF power amplifier Q2010 as a monitor signal. The carrier signal from the VCO Q1014 (2SC5555) passes through buffer amplifier Q1017 (2SC5555) and TX/RX switch D1010 (HSU277) The signal from D1010 is amplified by Q1029 (2SC3356), and Q1031 (2SK2973), and ultimately applied to the final amplifier Q1037 (2SK2974) which increases the signal level up to 5 watts output power. The transmit signal then passes through the antenna switch D1016 (RLS135), and is low-pass filtered to suppress away harmonic spurious radiation before delivery to the antenna. Automatic Transmit Power Control RF power output from the final amplifier is sampled by C1149/C1154 and is rectified by D1021 (HMS86WA). The resulting DC is fed through the Automatic Power Controller Q3012 (NJU7018U), thus allowing control of the power output. Transmit Inhibit When the transmit PLL is unlocked, pin 7 of PLL chip Q1013 (MB15A01PFV1) goes to a logic low. The resulting DC unlock control voltage is turns off TX inhibit switches Q1016 (2SA1602A), Q1018 (UMW1), and Q1020 (DTA143EE) to disable the supply voltage to transmitter RF amplifier Q1029, disabling the transmitter. Spurious Suppression Generation of spurious products by the transmitter is minimized by the fundamental carrier frequency being equal to the final transmitting frequency. Additional harmonic suppression is provided by a low-pass filter consisting of L1030, L1035, and L1036 and C1147, C1153, C1155, C1159, C1164, and C1167, resulting in more than 60 db of harmonic suppression prior to delivery of the RF signal to the antenna. PLL Frequency Synthesizer The PLL circuitry consists of VCO Q1014 (2SC5555), VCO buffers Q1017 and Q1021 (both 2SC5555), and PLL subsystem IC Q1013 (MB15A01PFV1), which contains a reference divider, serial-to-parallel data latch, programmable divider, phase comparator, and charge pump. Stability is maintained by a regulated 3.5 V supply via Q3023 (2SB1132Q) and Q3024 (S-812C35AUA-C2P), which feeds the PLL reference oscillator Q2030 (2SC4116GR), as well as capacitors associated with the MHz frequency reference crystal X2001. In the receive mode, VCO Q1014 oscillates between and MHz. The VCO output is buffered by Q1017 and Q1021, and applied to the prescaler section of Q1013. There the VCO signal is divided by 64 or 65, according to a control signal from the data latch section of Q1013, before being applied to the programmable divider section of Q1013. The data latch section of Q1013 also receives 8

9 Circuit Description serial dividing data from the microprocessor Q3026 (LC87F72C8A), which causes the pre-divided VCO signal to be further divided in the programmable divider section, depending upon the desired receive frequency, so as to produce a 5 khz derivative of the current VCO frequency. Meanwhile, the reference divider section of Q1013 divides the MHz crystal reference from the reference oscillator Q2030 by 3495 to produce the 5 khz loop reference. The 5 khz signal from the programmable divider (derived from the VCO) and that derived from the reference oscillator are applied to the phase detector section of Q1013, which produces a pulsed output with pulse duration depending on the phase difference between the input signals. This pulse train is filtered to DC and returned to the varactor D1007 (HVC350). Changes in the level of the DC voltage applied to the varactors affect the reactance in the tank circuit of the VCO, changing the oscillating frequency of the VCO according to the phase difference between the signals derived from the VCO and the crystal reference oscillator. The VCO is thus phase-locked to the crystal reference oscillator. The output of the VCO Q1014 is buffered by Q1017 before application to the 1st mixer, as described previously. For transmission, the VCO Q1014 oscillates between 118 and 137 MHz. The remainder of the PLL circuitry is shared with the receiver. However, the dividing data from the microprocessor is such that the VCO frequency is at the actual transmit frequency (rather than offset for IFs, as in the receiving case). Receive and transmit buses select which VCO is made active by Q1010 (RT1N241M). FET Q1019 (2SK880GR) buffers the VCV line for application to the tracking bandpass filters in the receiver front end. When the power saving feature is active, the microprocessor periodically signals to the PLL IC Q1013 to conserve power, and to shorten its lock-up time. Push-To-Talk Transmit Activation The PTT switch on the microphone is fed through the PTT controller, Q2001 (UMZ2N), to pin 28 of microprocessor Q3026, so that when the PTT switch is closed, pin 25 of Q3026 goes high. This sends the signal to cut off the receiver, by disabling the 3.5 V supply bus at Q1007 (DTA143EE) which feeds the front-end, FM IF subsystem IC Q2039, and receiver VCO circuitry. At the same time, Q1018 (UMW1) and Q1020 (DTA143EE) activate the transmiter s 3.5 V supply line to enable the transmitter. 9

11 Alignment Introduction The VXA-700 is carefully aligned at the factory for the specified performance across the Aircraft and Amateur bands. Realignment should therefore not be necessary except in the event of a component failure. The following procedures cover the adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts subsequently 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. If a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. 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. Problems caused by unauthorized attempts at realignment are not covered by the warranty policy Vertex Standard reserves the right to change circuits and alignment procedures, in the interest of improved performance, without notifying owners. The following test equipment (and familiarity with its use) is necessary for complete realignment. 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 signal 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. Correction of problems caused by misalignment resulting from use of improper test equipment is not covered under the warranty policy. Required Test Equipment Radio Tester with calibrated output level at 200 MHz In-line Wattmeter with 5% accuracy at 200 MHz 50-Ω, 10-W RF Dummy Load Regulated DC Power Supply adjustable from 3 to 15 VDC, 2A Frequency Counter: ±0.2 ppm accuracy at 200 MHz AF Signal Generator AC Voltmeter DC Voltmeter: high impedance VHF Sampling Coupler Alignment Preparation & Precautions A 50-Ω RF 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 next step to see if the same test equipment is 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 ~ 86 F (20 ~ 30 C). When the transceiver is brought into the shop from hot or cold air, it should be allowed some 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. Set up the test equipment as shown below for transceiver alignment, apply 7.4 VDC power to the transceiver. Notes: signal levels in db referred to in alignment are based on 0 dbµ = 0.5 µv (closed circuit). Test Equipment Setup 11
