FCC ID:K6610944620 IC: 511B-10944620 Circuit Description Vertex Standard Co., Ltd. VX-450 (UHF) Series Circuit Description 1. Circuit Configuration by Frequency The receiver is a Double-conversion Super-heterodyne with a first intermediate frequency (IF) of 67.65MHz 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 67.65MHz. This is then mixed with the 67.2MHz 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 RF signal from the antenna is delivered to the RF Unit and passes through Low-pass filer, antenna switching diode, high pass filter and removed undesired frequencies by varactor diode D1006,D1007 and D109,D1010 (tuned band-pass filer). The passed signal is amplified in Q1007 (BF1212WR) and moreover cuts an image frequency with the tuned band pass filter and comes into the 1st mixer. 2-2. First Mixer The 1st mixer consists of the Q1015 (3SK293). Buffered output from the VCO is amplified by Q1014 (2SC5005) to provide a pure first local signal between 332.35 and 402.35 MHz for injection to the first mixer. The IF signal then passes through monolithic crystal filters XF1001 (±7.5 kHz BW) to strip away all but the desired signal. 2-3. IF Amplifier The first IF signal is amplified by Q1025 (2SC5526). The amplified first IF signal is applied to FM IF subsystem IC Q1033 (NJM2591V) which contains the second mixer, second local oscillator, limiter amplifier, noise amplifier, and RSSI amplifier. The signal from reference oscillator X1001 becomes 4 times of frequencies in Q1033, it is mixed with the IF signal and becomes 450 KHz. The second IF then passes through the ceramic filter CF1001 or CF1002 to strip away unwanted mixer products, and is applied to the limiter amplifier in Q1033, which removes amplitude variations in the 450kHz IF, before detection of the speech by the ceramic discriminator CD1001 (ECDA450C24). 2-4. Audio amplifier Detected signal from Q1033 (NJM2591V) is inputted to Audio Processor IC Q1013 . The signal which appeared from Q1001 is in high pass filter Q1041 (NJM12902V). The signal which passed Q1041 goes to AF volume (VR1001). And then the signal goes to audio amplifier Q1048 (TDA2822L-50B).The output signal from J1006 is in audio speaker. 2-5. 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 2 to 13 is established in the middle of threshold and tight. The bigger figure is nearer the tight setting. The level 15 becomes setting of carrier squelch. FCC ID:K6610944620 IC: 511B-10944620 Circuit Description Vertex Standard Co., Ltd. 2-5-1. Noise Squelch Noise squelch circuit is composed of the band path filter and noise detector of Q1033. When a carrier isn't received, the noise ingredient which goes out of the demodulator Q1033 is amplified in Q1037 through the band path filter, is detected to DC voltage with D1031 and is inputted to 15 pin (the A/D port) of the Q1035 (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 Q1049 "OFF" by making the 90 pin (CPU) "L" level. When the detection voltage is low, the CPU makes Q1049 ON with making 90 pin "H" and the AF signal is output. 2-5-2. Carrier Squelch The CPU (14pin: A/D port) detect RSSI voltage output from Q1033 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 -1dBu (EMF) higher than squelch tight sensitivity. 3. Transmitter System 3-1. Mic Amplifier The AF signal from internal microphone MC2001 or external microphone J1004 in to Audio processor IC Q1013. (selected 34pin or 35pin) Q1013 is which contains the microphone amplifier, compandor, Pre-emphasis, limiter and splatter filter, the processed signal to made FM modulation to transmit carrier by the modulator D1014 (HVC383B) of VCO. Q1013 is built-in DTMF Receiver, and Inversion Type Encryption. 3-2. Drive and Final amplifier The modulated signal from the VCO Q1023 (2SC4227) is buffered by Q1017 (2SC5005) . Then the signal is buffered by Q1010 (2SC3336) for the final amplifier driver Q1015 (RQA0004PXDQS). The low-level transmit signal is then applied to Q1006 (RQA0011DNS) for final amplification up to 5watts output power. The transmit signal then passes through the antenna switch D1005 (HVU131) and is low pass filtered to suppress away harmonic spurious radiation before delivery to the antenna. 3-4. Automatic Transmit Power Control The current detector Q1040-1(NJM12904V) detects the current of Q1006 and Q1008, and converts the current difference to the voltage difference. The output from the current detector Q1040-1 is compared with the reference voltage and amplified by the power control amplifier Q1040-2. The output from Q1040-2 controls the gate bias of the final amplifiers Q1006 and the final amplifier driver Q1008. The reference voltage changes into four values (Transmit Power High and Low) controlled by Q1040 (NJM12904V). FCC ID:K6610944620 IC: 511B-10944620 Circuit Description Vertex Standard Co., Ltd. 3-5. PLL Frequency Synthesizer The frequency synthesizer consists of PLL IC, Q1036 (AK1541), VCO, TCXO (X1001). The output frequency from TCXO is 16.8MHz and the tolerance is +/- 2.5 ppm (in the temperature range -30 to +60 degrees). 3-5-1.

FCC ID:K6610944620 IC:511B-10944620 Alignment Vertex Standard Co., Ltd. 1 VX-450 (UHF) Series Alignment Introduction The VX-450 series are 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. FCC ID:K6610944620 IC:511B-10944620 Alignment Vertex Standard Co., Ltd. 2 Required Test Equipment ˆ RF Signal Generator with calibrated output level at 600MHz. ˆ Deviation Meter (linear detector) ˆ In-line Wattmeter with 5% accuracy at 600MHz. ˆ 50-Ω RF Dummy Load with power rating 10W at 600MHz. ˆ 4Ω/1W AF Dummy Load ˆ Regulated DC Power Supply (standard 7.5V DC, 3A) ˆ Frequency Counter with 0.2ppm accuracy at 600MHz. ˆ Audio Signal Generator (available to output 30Hz to 5kHz) ˆ AC Voltmeter ˆ DC Voltmeter ˆ IBM PC/compatible Computer with Microsoft Windows XP or later operating system ˆ Vertex Standard FIF-10A Connection Cable & CE115 Programming software. 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 0dB μ EMF = 1μV. Setup the test equipment as shown for transceiver alignment, apply 7.5V DC power to the transceiver. Refer to the drawings above for Alignment Points. The transceiver must be programmed for use in the intended system before alignment is attempted. The RF parameters are loaded from the file during the alignment process. In order to facilitate alignment over the complete switching range of the equipment it is recommended that the channel data in the transceiver is preset as the chart below. Channels Frequency (Simplex) UHF LOW (F1) 400.100MHz MID (F2) 435.100MHz HIGH (F3) 469.900MHz FCC ID:K6610944620 IC:511B-10944620 Alignment Vertex Standard Co., Ltd. 3 The alignment mode is accessed by “Alignment mode” command from the computer whilst switching on. And the alignment tool operates it automatically. During the alignment mode, normal operation is suspended. Use the alignment tool program running on PC. Before beginning alignment, connect the transceiver and PC using the FIF-10A Connection Cable, and run the CE115 Channel Programming Diskette, then download the data from the transceiver to the computer. Then store this data in a disk file so that it can be uploaded when alignment is finished. You should find the corresponding data file on the computer disk for the transceiver version you are aligning, containing channel settings for the high edge, middle and low edge of the transceiver’s frequency range in channels 1,2 and 3, respectively. Up-load this file to the tra…
