Set (Menu) Mode Functions One or more of the radio’s "Soft Keys" may be enabled for a function associated with the "Set" (Menu) mode. This feature, when activated, allows the user to customize certain performance aspects of the VX900. Note that some of these items may also appear as available "Soft Keys," described below. The operating procedure for the Menu mode is quite simple, requiring only a few easily- remembered actions on the user’s part.

Cloning The VX-900 includes a convenient “Clone” feature, which allows the programming data from one transceiver to be transferred to another VX-900. Here is the procedure for Cloning one radio’s data to another. 1. Turn both transceivers off. 2. Remove the plastic cap and its two mounting screws from the MIC/SP jack on the right side of the transceiver. Do this for both transceivers. 3. Connect the optional CT-72 cloning cable between the MIC/SP jacks of the two transceivers. 4.

Circuit Description Overview The VX-900 is a UHF FM hand-held transceiver designed to operate in the frequency range of 400 to 512 MHz. Circuit Configuration by Frequency The receiver is a double-conversion superheterodyne with a first intermediate frequency (IF) of 44.25 MHz and a second IF of 450 kHz. Incoming signals from the antenna are mixed with the local signal from PLL to produce the first IF of 44.25 MHz. This is then mixed with the 43.8 MHz second local oscillator (using the 14.
Circuit Description The resulting DC squelch control voltage is passed to pin 19 of the microprocessor Q1050. If no carrier is received, this signal causes pin 6 of Q1052 (BU2090FS) to go low and pin 89 of Q1050 to go high. Pin 6 of Q1052 signals Q1008 (CPH6102), Q1017 (UMC5N) and Q1020 (UMC5N) to disable the supply voltage to audio amplifiers Q1007 and Q1011, while pin 89 makes Q1014 (UMG2N) hold the green (Busy) half of the LED off, when pin 6 of Q1052 is low and pin 89 of Q1052 is high.
Circuit Description Transmit Inhibit utilizing a 40 or 50 kHz reference signal which is eighth multiple of the channel step size (5, 6.25 or 7.5 kHz). The input signal from pins 5 and 8 of the PLL IC is divided down to 40 or 50 kHz and compared at the phase comparator. The pulsed output signal of the phase comparator is applied to the charge pump and transformed into a DC signal in the loop filter. The DC signal is applied to the pin 1 of the VCO and locks to keep the VCO frequency constant.
Alignment Introduction The VX-900 is 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 when altering the version type. All component replacement and service should be performed only by an authorized VERTEX STANDARD representative, or the warranty policy may be voided.
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 0 dBµ EMF = 0.5 µV (closed circuit). Important Note When connecting the CT-71 plug into the MIC/ SP jack of the VX-900, you must remove the plastic cap and its mounting screws prior to programming.
Alignment portant that you follow the basic alignment sequence precisely, so that the displayed data and the data loaded into the transceiver are identical. Basic Alignment Sequence 1. Enter the alignment mode 2. Upload data from transceiver 3. Align data 4. Download data to transceiver Alignment Tool Menu Common Data The parameters in this section represent "common" data for all channels.
Alignment • Use the [t] or [u] key to select the "MID" fre- • Press the [space] key on the computer keyboard (1) Common RX : - [0] TIGHT NOISE SQUELCH This parameter is used to align the "Tight Noise Squelch" level. From the "(1) Common Rx" section, select [0] to enter this alignment sequence. to start alignment. This activates the transmitter, • Set the signal generator output level to –0dBµ quency channel in the alignment range. • Disable any subaudible tone signaling on this channel, if present.
Alignment Channels The following parameters may be adjusted individually for each channel. For example, minor variations in the power output across the operating band may be equalized by following this section’s instructions. • Press the [p] or [q] key, as needed, to set the deviation to the desired value (typically 3.9~4.2 kHz, or 2.0~2.3 kHz for "narrow band" channels). • When the desired deviation level is attained, press [ENTER] to lock in the new value.
