Ì If you have a Speaker/Microphone, we recommend that it not be connected until you are familiar with the ba- sic operation of the VX-410/-420. Operation Quick Start Ì Turn the top panel’s VOL/ PWR knob clockwise to turn on the radio on.
Operating Manual Reprint Key Function The VX-420 series provides programmable [ A ] , [ B ] , [ C ] , and [ D ] function keys, and both the series provide programmable switchs. These “Soft” keys functions can be customized (set to other functions), via programming by your VER- TEX STANDARD dealer, to meet your communications/ network requirements.

The VX-410/-420 series includes a convenient Cloning feature, which allows the programming data from one trans- ceiver to be transferred to another VX-410/-420 series. Here is the procedure for Cloning one radio's data to another. 1. Turn both transceivers off.
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 (RLS135). 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,...
Circuit Description ode D1048 (HSC277TRF) to the buffer amplifier Q1024 (2SC5005), pre driver amplifier Q1020 (2SC3357), driver amplifier Q1014 (RD01MUS1), and then the am- plified transmit signal is applied to the final amplifier Q1008 (RD07MVS1), which delivers up to 5 watts of output power.
Introduction The VX-410/-420 series has been aligned at the fac- tory for the specified performance across the entire fre- quency range specified. Realignment should therefore not be necessary except in the event of a component failure. All component replacement and service should be per- formed only by an authorized Vertex Standard representa- tive, or the warranty policy may be voided.
Alignment Set up the test equipment as shown below for trans- ceiver alignment, and apply 7.5V DC power to the trans- ceiver. Inline Wattmeter RF Sampling Deviation Meter Coupler CT-42 connection Cable Frequency Counter COM port The transceiver must be programmed for use in the intended system before alignment is attempted.
PLL VCV (Varactor Control Voltage) Ì Connect the DC voltmeter between Main Unit and ground. Ì Set the transceiver to CH 3 (high band edge), and ad- just on the Main Unit for 4.0 V ± 0.1 V on the DC voltmeter.
Alignment CTCSS Deviation Ì Set the transceiver to CH 2 (band center). Ì To adjustment, click the left mouse button on the “CTCSS Modulation” box, then press the [ ENTER ] key to open the pop-up window. Ì Use the [ ] or [ ] arrow keys so that the deviation meter reading is ±0.8 kHz (±0.1 kHz) (for 25 kHz steps) or ±0.4 kHz (±0.1 kHz) (for 12.5 kHz steps) deviation.
