FCC ID: K6610573X20 IC ID: 511B-10573X20 Circuit Description 1/3 Vertex Standard Co., Ltd. VXA-300 Circuit Description Receive Signal Path Incoming RF from the antenna jack is passed through a low-pass filter and high-pass filter consisting of coils L1022, L1025, L1026, L1027, L1028 & L1029, capacitors C1271,C1276,C1277,C1278,C1280,C1281,C1282,C1283,C1285,C1286,C1289,C1290,C1 293,C1294 & C1295 and antenna switching diodes D1039 and D1042 to the receiver front end section. Signals within the frequency range of the transceiver is applied to the receiver front end which contains RF amplifier Q1076 and varactor-tuned band-pass filter consisting of coils L1014, L1017, L1018, L1019, L1024, L1025 & L1031, capacitors C1241, C1243, C1245, C1246, C1248, C1250, C1255, C1256, C1259, C1266, C1272 & C1273, and diodes D1034, D1035, D1038 & D1041, then applied to the 1st mixer Q1068. Buffered output from the VCO is amplified by Q1049 to provide a pure 1st local signal between 143.4 and 172.4 MHz for injection to the 1st mixer. The 35.4 MHz 1st mixer product then passes through monolithic crystal filter XF1001 (7.5 kHz BW) which strips away all but the desired signal, which is then amplified by mixer post-amp Q1061. The amplified 1st IF signal is applied to the AM/FM IF subsystem IC Q1058, which contains the 2nd mixer, 2nd local oscillator, limiter amplifier, noise amplifier and AM/FM detector. A 2nd local signal is generated by PLL IC Q1041 from the 17.475 MHz crystal X1002 .The17.475MHz signal is doubled by Q1054 to produce the 450 kHz 2nd IF when mixed with the 1st IF signal within Q1058. The 2nd IF then passes through the ceramic filter CF1001 to strip away unwanted mixer products. In the FM mode, a 2nd IF signal from the ceramic filter CF1001 applied to the limiter amplifier section of Q1058, which removes amplitude variations in the 450 kHz IF before detection of the speech by the ceramic discriminator CD1001. Detected audio from Q1058 is passed through the de-emphasis, consisting of the resistors R1144, R1152, R1155 & R1199, capacitors C1118, C1119, C1124, C1149 & C1151, and Q1037-2. In the AM mode, detected audio from Q1058 is passed through the audio amplifier Q1037- 1 and ANL circuit, then applied to the AF amplifier Q1037-2. When impulse noise received, a portion of the AM detector output signal from the AM/FM IF subsystem Q1058, including pulse noise is rectified by D1019. The resulting DC is applied to the ANL MUTE gate Q1039, thus reducing the pulse noises. The processed audio signal from Q1037-1 is passed through the AF mute and amplifier Q1037-2 to the audio tone equalizer Q1021, Q1018, Q1023, Q1026 and Q1020. The equalized audio signal is passed through the volume control to the audio power amplifier Q1001, providing up to 0.8 Watts to 16 Ω loudspeaker or audio power amplifier Q1005, providing up to 0.4 Watts to 8 Ω the headphone jack. A portion of the AF signal from the AM/FM IF subsystem Q1058 converted into DC voltage within the IC, and then passes through the AGC amplifier Q1063 and Q1066 to the inversion amplifiers Q1075 and Q1062. These amplifier reduce the amplifier gain of the IF amplifier Q1061 and the RF amplifier Q1076 while receiving a strong signal. Squelch Control When signal is received, appear the DC squelch control voltage at pin 15 of AM/FM IF subsystem Q1058 according to the receiving signal strength. This DC is applied to pin 16 of microprocessor Q1024. The DC squelch control voltage is compared with the SQL threshold level by the microprocessor Q1024. If the DC squelch control voltage is lower, pin 7 of Q1024 goes high. This signal activates the AF MUTE gate Q1037-2, thus disabling the AF audio. Also, the microprocessor stops scanning, if active, and allows audio to pass through the AF MUTE gate Q1037-2. FCC ID: K6610573X20 IC ID: 511B-10573X20 Circuit Description 2/3 Vertex Standard Co., Ltd. Transmit Signal Path Speech input from the microphone is passed through the microphone amplifier Q1011-1, then applied to the ALC amplifier Q1017. The amplified speech signal is passed through the high-pass filter Q1011-3 and low-pass filter Q1011-4, which adjust the modulation level, then fed to the AM modulator Q1069. When using the optional headset, the SIDETONE signal from J1002 becomes “HIGH”, turning Pin10 of Q1024 on; pin 91 of Q1024 therefore a portion of the speech signal applied to the AF power amplifier Q1001 as a monitor signal. The carrier signal from the VCO Q1046 passes through the buffer amplifier Q1049 and TX/RX switch D1026. The signal from D1026 is amplified by Q1060 and Q1064, and ultimately applied to the final amplifier Q1069 which increases the signal level up to 5 watts output power. The transmit signal then passes through the antenna switch D1039, 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 C1275/C1279 and is rectified by D1043. The resulting DC is fed through the Automatic Power Controller Q1074, thus allowing control of the power output. Transmit Inhibit When the transmit PLL is unlocked, pin 7 of PLL chip Q1041 goes to a logic low. The resulting DC “unlock” control voltage is switches off TX inhibit switches Q1053, and Q1055 to disable the supply voltage to transmitter RF amplifiers Q1048 and Q1049, 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 L1025, L1028 & L1029 and C1271, C1280, C1282, C1285, C1289 & C1293, resulting in more than 60 dB of harmonic suppression prior to delivery of the RF signal to the antenna. PLL Frequency Synthesizer PLL circuitry consists of VCO Q1046, VCO buffer Q1049 & Q1051, and PLL subsystem IC Q1041, which contains a reference divider, serial-to-paralle…

FCC ID: K6610573X20 IC ID: 511B-1053X20 Alignment 1/4 Vertex Standard Co., Ltd. VXA-300 Alignment Introduction The VXA-300 is carefully aligned at the factory for the specified performance across the Aircraft and Weather 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 ο Radio Tester with calibrated output level at 200 MHz ο In-line Wattmeter with 5 % accuracy at 200 MHz ο 50 Ω, 10 W RF Dummy Load ο Regulated DC Power Supply adjustable from 3 to 15 VDC, 2 A ο Frequency Counter: ±0.2 ppm accuracy at 200 MHz ο AF Signal Generator ο AC Voltmeter ο DC Voltmeter: high impedance ο 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 20 - 30 °C (68 - 86 °F). 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 FCC ID: K6610573X20 IC ID: 511B-1053X20 Alignment 2/4 Vertex Standard Co., Ltd. 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 7.2 VDC power to the transceiver.
