Introduction
This manual provides technical information necessary for servicing the VX-3200U Transceiver.
Servicing this equipment requires expertise in handling surface-mount chip components. Attempts by non-qualified
persons to service this equipment may result in permanent damage not covered by the warranty, and may be illegal in
some countries.
Two PCB layout diagrams are provided for each double-sided circuit board in the transceiver. Each side of thr board is
referred to by the type of the majority of components installed on that side (“leaded” or “chip-only”). In most cases one
side has only chip components, and the other has either a mixture of both chip and leaded components (trimmers, coils,
electrolytic capacitors, ICs, etc.), or leaded components only.
While we believe the technical information in this manual to be correct, Vertex Standard assumes no liability for damage
that may occur as a result of typographical or other errors that may be present. Your cooperation in pointing out any
inconsistencies in the technical information would be appreciated.

Circuit Description
1. Overview
The VX-3200U is a UHF FM mobile transceiver designed
to operate in the frequency range of 400 to 512MHz.
2. Circuit Configuration by Frequency
The receiver is a double-conversion superheterodyne with
a first intermediate frequency (IF) of 44.25MHz and a second IF of 450kHz. Incoming signals from the antenna are
mixed with the local signal from PLL to produce the first
IF of 44.25MHz.
This is then mixed with the 43.8MHz second local oscillator (using the 14.6MHz reference crystal) output to produce the 450kHz second IF. This is detected to give the
demodulated signal.
The transmit signal frequency is generated by PLL VCO,
and modulated by the signal from the microphone. It is
then amplified and sent to the antenna.
3. Receive Signal Path
Incoming RF signals from the antenna connector are delivered to the RF Unit, and pass through a low-pass filter
(LPF) antenna switching network consisting of coils L1001,
L1002, L1003, L1004, and L1005, capacitors C1004, C1008,
C1009, C1011, and C1014, and antenna switching diodes
D1005 and D1007 (both UM9957F) for delivery to the re-
ceiver front end.
Signals within the frequency range of the transceiver are
then passed through a varactor-tuned bandpass filter consisting of L1008, L1009 before RF amplification by Q1011
(2SC4226).
The amplified RF is then band-pass filtered again by varactor-tuned resonators L1019, L1023 to ensure pure inband input to 1st mixer Q1038 (GN2011).
Buffered output from the VCO Unit is amplified by Q1021
(2SC5107) and low-pass filtered by L1030/L1031 and
C1184/C1188/C1192, to provide a pure 1st local signal
between 355.75 and 467.75MHz to the 1st mixer.
The 44.25MHz 1st mixer product then passes through dual
monolithic crystal filters XF1001 and XF1002, and is amplified by Q1029 (2SC4215Y) and delivered to the input
of the FM IF subsystem IC Q1028 (TA31136FN).
This IC contains the 2nd mixer, 2nd local oscillator, limiter amplifier, FM detector, noise amplifier, and squelch
gates.
The 2nd LO in the IF-IC is produced from crystal X1001
(14.600MHz), and the 1st IF is converted to 450kHz by the
2nd mixer and stripped of unwanted components by ceramic filter CF1001 or CF1002. After passing through a
limiter amplifier, the signal is demodulated by the FM
detector CD1001 (CDBC450CX24).
Detected audio from Q1028 (TA31136FN) is applied to
Q2016 (AK2345) and audio low-pass filter. After volume
adjustment by Q2014 (M62364FP), the audio signal is amplified by the AF power amplifier Q1509 (TDA2003H) and
passed to speaker jack.
4. Transmit Signal Path
Voice audio from the microphone is delivered via the MIC
(Jack) Unit to the PANEL Unit, after passing through
amplifier Q2022(NJM2902V), Mic gain-volume Q2014
(M62364FP) pre-emphasis Q2015 (NJM2902V), and limiter Q2016 (IDC instantaneous deviation control), is adjusted for optimum deviation level and delivered to the
next stage.
Voice input from the microphone and CTCSS are FMmodulated to the VCO of the synthesizer, while DCS audio is modulated by the reference frequency oscillator of
the synthesizer.
Synthesizer output, after passing through diode switch
D1022 (1SS321), is amplified by driver Q1025
(2SC5415E), Q1026 (2SC5107) and power module Q1039
(RA45H4452M) to obtain full RF output. The RF energy
then passes through antenna switch D1005/D1007 and a
low-pass filter circuit and finally to the antenna connector.
RF output power from the final amplifier is sampled by
CM coupler and is rectified by D1011, D1012 (both
HSM88AS). The resulting DC is fed through Automatic
Power Controller Q1003 (M5223AGP), Q1002
(RT1N241M), Q1032 (RT1N241M), Q1022 (RT1N241M),
and TH1003 to transmitter RF amplifier and thus the power output.
Generation of spurious products by the transmitter is minimized by the fundamental carrier frequency being equal
to the final transmitting frequency, modulated directly in
the transmit VCO. Additional harmonic suppression is
provided by a low-pass filter consisting of coils L1001,
L1003, L1004, capacitors C1004, C1008, C1009, C1011, and
C1014, resulting in more than 70dB of harmonic suppression prior to delivery to the RF energy to the antenna.
5. PLL Frequency Synthesizer
PLL frequency synthesizer consists of the VCO Q1013
(2SK508-K52: RX) and Q1015 (2SC4226-R24: TX), VCO
buffers Q1018, Q1020, Q1021 (all 2SC5107-0), PLL subsystem IC Q1023 (MB15A02PFV) and 14.6MHz reference
crystal X1001.
The frequency stability is ±2.5ppm within temperature
range of –30 to +60 degree. The output of the 14.6MHz
reference is applied to pin 8 of the PLL IC.
While receiving, VCO Q1013 oscillates between 355.75 and
467.75MHz according to the transceiver version and the
programmed receiving frequency. The VCO generates
355.75 to 467.75MHz for providing to the first local signal. In TX, the VCO generates 400 to 512MHz.
9
Circuit Description
The output of the VCO is amplified by the Q1020 and routed to the pin 5 of the PLL IC. Also the output of the VCO
is amplified by the Q1021 and routed first local/Power
Module according to D1022.
The PLL IC consists of a prescaler, fractional divider, reference divider and phase comparator and charge pump.
This PLL IC is fractional-N type synthesizer and performs
in the 40 or 50 kHz reference signal, which is eighth of the
channel step (5 or 6.25 kHz). The input signal from pin 5
and 8 of the PLL IC is divided down to the 20 kHz and
compared at phase comparator. The pulsed output signal
of the phase comparator is applied to the charge pump
and transformed into DC signal in the loop filter. The DC
signal is applied to the VCO and locked to keep the VCO
frequency constant.
PLL data is output from "DCS_E" (pin100), "CLOCK"
(pin2) and "PLL_E" (pin98) of the microprocessor Q2013.
The data are input to PLL IC when the channel is changed
or when transmission is changed to reception and vice
versa. A PLL lock condition is always monitored by the
pin20 of the Q2013. When the PLL is unlocked, the UL
goes low.

Alignment
Introduction
The VX-3200U 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 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.

Alignment Preparation & Precautions
A 50W 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 68°F
and 86°F (20°C ~ 30°C). 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 0dBm EMF = 0.5mV.
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.
