FCC ID: K6610504420 IC ID: 511B-10504420 Circuit Description 1/3 Vertex Standard Co., Ltd. VX-417/427 Circuit Description 1. Receive Signal Path Incoming RF from the antenna jack is delivered to the RF Unit and passes through a low- pass filter consisting of coils L1001, L1002, and L1003, capacitors C1001, C1002, C1021, C1022, C1023, C1024, C1025, C1026, and C1027, and antenna switching diode D1004. Signals within the frequency range of the transceiver enter a Varactor-tuned band-pass filter consisting of coils L1012 and L1015, capacitors C1058, C1059, C1085, C1118 and C1119, and diodes D1007, D1008, D1009 and D1010, then amplified by Q1019 and enter a Varactor-tuned band-pass filter consisting of coils L1019, L1020 and L1025, capacitors C1122, C1150, C1151, C1152, C1153, C1154, C1155, C1156, C1177, C1178, C1179, C1180 and C1181, and diodes D1012, D1013, and D1016, before first mixing by Q1029. Buffered output from the VCO is amplified by Q1026 to provide a pure first local signal between 399.15 and 439.15 MHz for injection to the first mixer Q1029. The 50.85 MHz first mixer product then passes through monolithic crystal filter XF1001 (5.5 kHz BW) to strip away all but the desired signal, which is then amplified by Q1041. The amplified first IF signal is applied to FM IF subsystem IC Q1048, which contains the second mixer, second local oscillator, limited amplifier, noise amplifier, and RSSI amplifier. A second local signal is produced from the PLL reference/second local oscillator of X1002 (TCXO, 16.80 MHz). The 16.80 MHz reference signal is tripled by Q1048 and capacitor C1251, coil L1042, then resulting the 50.40 MHz second local signal delivered to mixer section of Q1048 which produce the 450 kHz second IF mixed with the first IF signal. The second IF then passes through the ceramic filter CF1001 (on “Narrow” channels) or CF1002 (on “Wide” and ”Narrow” channels) to strip away unwanted mixer products, and is then applied to the limited amplifier in Q1048, which removes amplitude variations in the 450kHz IF, before detection of the speech by the ceramic discriminator CD1001. 2.Audio Amplifier The demodulated audio signal from the Q1048 passes through a low-pass filter and High-pass filter to the Voice Scrambler Unit when the optional Scrambler Unit is installed, then applied to the de-emphasis Q1021 via the dummy unit. The audio signal is applied to the expander Q1021 or switch circuit consisting of Q1009 and Q1011. The output from Q1021 or Q 1011 passes through the audio volume and the audio power amplifier Q1005, providing up to 500 mW of audio power to the 4 Ω loudspeaker. 3. Squelch Control The squelch circuitry consists of a noise amplifier and band-pass filter and noise detector within Q1048. When no carrier received, noise at the output of the detector stage in Q1048 is amplified and band-pass filtered by the noise amplifier section of Q1048 and the network between pins 7 and 8, and then rectified by detection circuit in Q1048. The resulting DC squelch control voltage is passed to pin 19 of the microprocessor Q1047. If no carrier is received, this signal causes pin 19 of Q1047 to go high and pin 30 to go high. Pin 35 signals Q1006 to disable the supply voltage to the audio amplifier Q1005, while pin 30 hold the green (Busy) half of the LED off, when pin 35 is high and pin 30 is high. Thus, the microprocessor blocks output from the audio amplifier, and silences the receiver, while no signal is being received (and during transmission, as well). When a carrier appears at the discriminator, noise is removed from the output, causing pin 19 of Q1047 to go low and the microprocessor to activate the ”Busy” LED via Q1047. The microprocessor then checks for CTCSS or CDCSS code squelch information, if enabled. If not transmitting and CTCSS or CDCSS is not activated, or if the received tone or code matches that programmed, allows audio to pass through the audio amplifier Q1005 to the loudspeaker by enabling the supply voltage to it via Q1048. FCC ID: K6610504420 IC ID: 511B-10504420 Circuit Description 2/3 Vertex Standard Co., Ltd. 4. Transmit Signal Path The speech input from the microphone MC1001 passes through the audio amplifier Q1021 to Q1015, which is, adjusted the microphone gain. The adjusted audio is applied to the compounder Q1010, which is, compressed the speech signal according to the control command from the microprocessor Q1047. The compressed speech signal passes through the dummy unit and pre-emphasis circuit to Q1021, which contains the low-pass filter, Voice Scrambler selector, and high-pass filter. The output from Q1021 is applied to the AF Mute gate Q1055, then return to Q1021, which contains the limiter amplifier, Low pass filter and audio amplifier. The filtered audio signal is applied to Q1015 which is adjusted the audio level, then is applied to varactor diode D1017, which frequency modulates the VCO Q1033. A portion of the audio signal from Q1015 is applied to TCXO X1002. The processed audio may then be mixed with a CTCSS tone generated by Q1047 for frequency modulation of the PLL carrier (up to ±5 kHz from the unmodulated carrier) at the transmitting frequency. If a CDCSS code is enabled for transmission, the code is generated by microprocessor Q1047 and delivered to X1002 (TCXO, 16.80 MHz) for CDCSS modulating. The modulated signal from the VCO Q1033 is buffered by Q1026. The low-level transmit signal is then passes through the TX switching diode D1048 to the buffer amplifier Q1024, pre driver amplifier Q1020, driver amplifier Q1014, then amplified transmit signal is applied to the final amplifier Q1008 up to 5.0 watts output power. The transmit signal then passes through the antenna switch D1004 and is low-pass filtered to suppress harmonic spurious radiation before delivery to the antenna. 4-1 Automatic Transmit Power Control Current from the final amplifier is sampled by R1015, R1038 and R1040, and is rectified by Q1003.

FCC ID: K6610504420 IC ID: 511B-10504420 Alignment 1/3 Vertex Standard Co., Ltd. VX-417/427 Alignment The VX-417/427 has been carefully aligned at the factory for the specified performance across the frequency range specified for each version. Re-alignment should therefore not be necessary except in the event of component failure, or altering version type. All component replacement and service should only be performed by an authorized VERTEX STANDARD representative, or the warranty policy may be void. Required Test Equipment ・ CT-42 Programming Cable with CE64 Channel Programming Diskette ・ RF Signal Generator with calibrated output level at 1 GHz ・ Deviation Meter (Linear Detector) ・ AC Voltmeter ・ SINAD Meter ・ In-Line Wattmeter with 5 % accuracy at 500 MHz ・ Regulated DC Power Supply adjustable from 4 to 10 V, 3 A ・ 50 Ω Non-reactive Dummy Load: 10 W at 500 MHz ・ Frequency Counter: ±0.2 ppm accuracy at 500 MHz ・ AF Signal Generator ・ DC Voltmeter: High impedance Before beginning alignment, connect the transceiver and PC using the CT-42 Programming Cable, and run the CE64 Channel Programming Diskette, then download the EEPROM 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 transceiver. Low Band Edge (Channel 1):450.000MHz Band Center(Channel 2):470.000MHz High Band Edge (Channel 3):490.000MHz Note: Signal levels in dB referred in the alignment procedure are based on 0 dBμ= 0.5 μV. PLL & Transmitter Set up the test equipment as shown for transmitter alignment. Adjust the supply voltage to 7.5 V for all steps where not specified otherwise. PLL VCV (Varactor Control Voltage) ・ Connect the DC voltmeter between TP1045 on the Main Unit and Ground. ・ Set the transceiver to CH3 (high band edge), and adjust L1036 on the Main Unit for 3.9 V ±0.1 V on the DC voltmeter, while receiving. ・ Set the transceiver to CH3 (high band edge), and adjust L1038 on the Main Unit for 4.0 V ±0.1 V on the DC Voltmeter, while transmitting. ・ Set the transceiver to CH1 (low band edge), and confirm the low-end VCV is more than 1.0 V while receiving, and more than 1.1 V while transmitting. PLL Reference ・ Set the transceiver to CH2 (band center). ・ Open the “Alignment” window on the CE64, and then select “RF frequency” parameter. FCC ID: K6610504420 IC ID: 511B-10504420 Alignment 2/3 Vertex Standard Co., Ltd. ・ Press the [ENTER] key to enable programming of this parameter, use the [LEFT] or [RIGHT] arrow keys so that the frequency counter displays band center frequency ±100 Hz (for the version being aligned). Transmitter Output Power ・ Set the transceiver to CH2 (band center). ・ Open the “Alignment” window on the CE64, and then select “RF Power (High)” parameter. ( only when “Pwr H/L” parameter is select “H”) ・ Press the [ENTER] key to enable programming of this…
