Introduction

This manual provides the technical information necessary for servicing the VX-4200/-4100 Series Mobile Transceiver.

Servicing this equipment requires expertise in handing 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 board in this transceiver. Each side of the board is
referred to by the type of the majority of components installed on that side (“Side A” or “Side B”). In most cases one
side has only chip components (surface-mount devices), and the other has either a mixture of both chip and leaded
components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.

As described in the pages to follow, the advanced microprocessor design of the VX-4200/-4100 allows a complete
alignment of this transceiver to be performed without opening the case of the radio; all adjustments can be performed
from the personal computer, using with the Vertex Standard VPL-1 Programming Cable and CE59 Software.

While we believe the 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

ENGESBRA Distribuidor Autorizado Vertex Standard | www.engesbra.com.br/vertex | Tel.[phone]

1. Circuit Configuration by Frequency

The receiver is a double-conversion superheterodyne with a first
intermediate frequency (IF) of 50.85 MHz 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 50.85
MHz. This is then mixed with the 50.4 MHz second local oscil­lator output to produce the 450 kHz 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 FR signal from the antenna is delivered to the RF Unit
and passes through Low-pass filer, antenna switching diode, and
removed undesired frequencies by varactor diode (tuned band­pass filer: T1001, T1002 and T1003). The passed signal is am­plified in Q1022 (2SC3357) and moreover cuts an image fre-
quency with the band path filter and comes into the 1st mixer.
The Q1020 (2SA1774) controls bias of Q1022 (2SC3357).

2-2. First Mixer

The 1st mixer consists of the Q1035 (SPM5001), T1004, T1005
and T1006. Buffered output from the VCO is amplified by Q1038
(2SC5226) to provide a pure first local signal between 184.85
and 224.85 MHz for injection to the first mixer. The output IF
signal is amplified by Q1046 (2SC3357) and enters from the
mixer to the crystal filter. The IF signal then passes through
monolithic crystal filters XF1001 (±5.5 kHz BW) to strip away
all but the desired signal.

2-3. IF Amplifier

The first IF signal is amplified by Q1059 (2SC5226). The am-
plified first IF signal is applied to FM IF subsystem IC Q1079
(TA31136FN) which contains the second mixer, second local
oscillator, limiter amplifier, noise amplifier, and S-meter ampli­fier. The signal from reference oscillator X1003 becomes 3 times
of frequencies in Q1079 (TA31136FN), it is mixed with the IF
signal and becomes 450 kHz. The second IF then passes through
the ceramic filter CF1001 (for wide channels), CF1002 (for
narrow channels) to strip away unwanted mixer products, and is
applied to the limiter amplifier in Q1038 (2SC5226), which
removes amplitude variations in the 450 kHz IF, before detec­tion of the speech by the ceramic discriminator CD1001.

2-4. Audio amplifier

Detected signal from Q1079 (TA31136FN) is inputted to Q1037
(AK2345) and is output through the band path filter inside
Q1037 (AK2345). When the optional unit is installed, the Q1063
(BU4066BCFV) is made “OFF” and the AF signal from Q1037
(AK2345) goes the optional unit. When the optional unit is not
installed, Q1037 (AK2345) is made “ON” and the signal goes
through Q1063 (BU4066BCFV). The signal then goes through

AF mute switch Q1068 (BU4066BCFV), de-emphasis part and
expander Q1021 (LA8630M). When the function of expander
is off, the 1021 will be bypassed by Q1069 (TAR5S50). The
output signal of expander (or a signal from de-emphasis) is am­plified by Q1088 (NJM12902V) and it is amplified with AF
power amplifier Q1005 (TDA1519CTH) after passing AF vol-
ume Q1029 (M62364FP). The output of Q1005
(TDA1519CTH) drives a speaker (it chooses the external SP
or internal SP in J6001).

2-5. Squelch Circuit

There are 13 levels of squelch setting from 0 to 12. The level 0
means open the squelch. The level 1 means the threshold setting
level and level 11 means tight squelch. From 2 to 10 is estab­lished in the middle of threshold and tight. The bigger figure is
nearer the tight setting. The level 12 becomes setting of carrier
squelch.

2-5-1. Noise Squelch

Noise squelch circuit is composed of the band path filter of
Q1079 (TA31136FN), noise amplifier Q1091 (2SC4617), and
noise detector D1059, D1061 (both DA221). When a carrier
isn’t received, the noise ingredient which goes out of the de­modulator Q1079 (TA31136FN) is amplified in Q1091
(2SC4617) through the band path filter Q1079 (TA31136FN),
is detected to DC voltage with D1059, D1061 (both DA221)
and is inputted to 19 pin (the A/D port) of the Q1083 (CPU:
LC87F74C8A). 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 Q1068 (BU4066BCFV) “OFF” by making the 40pin “L”
level. When the detection voltage is low, the CPU makes Q1068
“ON” with making 40pin “H” and the AF signal is output.

2-5-2. Carrier Squelch

The pin 18 (A/D port) of Q1083 (CPU: LC87F74C8A) detect
RSSI voltage output from pin 12 of Q1079 (TA31136FN), 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
3dB higher than squelch tight sensitivity.

3. Transmitter System

3-1. Mic Amplifier

The AF signal from microphone jack J4001 (4ch) or J5001
(501ch) is amplified with microphone amplifier Q1066, is am­plified with 2nd microphone amplifier Q1088 after microphone
selection switch Q1016, and passes microphone gain volume
Q1029. The AF signal which was controlled in the correct gain
passes compandor Q1021. When not using a compandor, with
the control from the CPU, it passes in the compandor circuit
inside of Q1021 (LA8630M) and it is output and it passes a

pre-emphasis circuit. Q1063 (BU4066BCFV) becomes “OFF”
when an option unit is attached and the AF signal from Q1037
(AK2345) goes via the option unit. When an option unit isn’t
attached, Q1063 (BU4066BCFV) becomes “ON,” the signal
passes Q1063 (BU4066BCFV) and is input to Q1037
(AK2345). The signal passed limiter and splatter filer of Q1037
(AK2345) is adjusted by maximum deviation adjustment vol­ume Q1029 (M62364FP). The adjusted low frequency signal
ingredient is amplified by Q1074 (NJM12902V), added modu-
lation terminal of TCXO (X1003), the FM modulation is made
by reference oscillator. The high frequency signal ingredient is
amplified Q1074 (NJM12902V), and adjusted the level by
volume Q1029 (M62364FP) to make frequency balance be­tween low frequency. After that, it is made FM modulation to
transmit carrier by the modulator D1030 (HVC383B) of VCO.

3-2. Drive and Final amplifier

The modulated signal from the VCO Q1054 (2SK508) is buff-
ered by Q1049 (2SC5226) and amplified by Q1038 and Q1002
(both 2SC5226). The low-level transmit signal is then applied
to the Power Module Q1028 (S-AV32) for final amplification
up to 50 watts output power. The transmit signal then passes
through the antenna switch D1006 (UM9957F) and is low-pass
filtered to suppress away harmonic spurious radiation before
delivery to the antenna.

3-3. Automatic Transmit Power Control

The output power of Power Module is detected by CM coupler,
it is detected by D1013 and D1014 (both HSM88AS) and is
input to comparator Q1090 (NJM12902V). The comparetor
compares two different voltages and makes output power stable
by controlling the bias voltage of Power Module. There are 3
levels of output power (Hi, Mid and Lo), it is switched by the
voltage of Q1029-1 (M62364FP).

3-4. PLL Frequency Synthesizer

The frequency synthesizer consists of PLL IC Q1085
(SK7025DK), Q1045 (DTC114TE), VCO, TCXO (X1003) and
buffer amplifier. The output frequency from TCXO is 16.8 MHz
and the tolerance is ±2.5 ppm (in the temperature range -30 to
+60 degrees).

3-4-1. VCO

While the radio is receiving, the RX oscillator Q1054 (2SK508)
in VCO generates a programmed frequency between 184.85 and

224.85 MHz as 1st local signal. While the radio is transmitting,
the TX oscillator Q1058 (2SC3356) in VCO generates a fre-
quency between 134 and 174 MHz. The output from oscillator
is amplified by buffer amplifier Q1049 (2SC5226) and becomes
output of VCO. The output from VCO is divided, one is ampli­fied by Q1057 (2SC5226) and feed back to pin 5 of the PLL IC
Q1085 (SK7025DK). The other is amplified in Q1038
(2SC5226) and in case of the reception, it is put into the mixer
as the 1st local signal through D1022 (DA221), in transmis-
sion, it is amplified in Q1038 (2SC5226), and more amplified
in Q1002 (2SC5226) through D1022 (DA221) and it is put the
input terminal of the Power Module Q1028 (S-AV32).

3-4-2. VCV CNTL

Tuning voltage (VCV) of VCO is expanding the lock range of
VCO by controlling the anode of varactor diode at the negative
voltage and the control voltage from PLL IC Q1085
(SK7025DK). The negative voltage is added to the varactor
diode after converted to negative by Q1035 (SPM5001), which
is output voltage of D/A converter Q1029 (M62364FP).

3-4-3. PLL

The PLL IC Q1085 (SK7025DK) consists of reference divider,
main divider, phase detector, charge pumps and fractional accu­mulator. The reference frequency from TCXO is inputted to pin
8 of PLL IC Q1085 (SK7025DK) and is divided by reference
divider. This IC is decimal point dividing PLL IC Q1085
(SK7025DK) and the dividing ratio becomes 1/8 of usual PLL
frequency step. Therefore, the output of reference divider is 8
times of frequencies of the channel step. For example, when the
channel stepping is 5 kHz, the output of reference divider be­comes 40 kHz. The other hand, inputted feed back signal to pin
5 of PLL IC Q1085 (SK7025DK) from VCO is divided with
the dividing ratio which becomes same frequency as the output
of reference divider. These two signals are compared by phase
detector, the phase difference pulse is generated. The phase dif­ference pulse and the pulse from fractional accumulator pass
through the charge pumps and LPF. It becomes the DC voltage
(VCV) to control the VCO. The oscillation frequency of VCO
is locked by the control of this DC voltage. The PLL serial data
from CPU Q1083 (LC87F74C8A) is sent with three lines of
SDO (pin 2), SCK (pin 1) and PSTB (pin 3). The lock condition
of PLL is output from the UL (pin 18) terminal and UL becomes
“H” at the time of the lock condition and becomes “L” at the
time of the unlocked condition. The CPU Q1083
(LC87F74C8A) always watches over the UL condition, and
when it becomes “L” unlocked condition, the CPU Q1083
(LC87F74C8A) prohibits transmitting and receiving.

Introduction

The VX-4100/-4200 series has been aligned at the factory
for the specified performance across the entire frequency
range specified. Realignment should therefore not be nec­essary except in the event of a component failure. All com­ponent replacement and service should be performed only
by an authorized Vertex Standard representative, or the
warranty policy may be voided.

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 are replaced, 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
must reserve 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 the need for 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.

Alignment Preparation & Precautions

A 50-ohm 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.

Beacuse of the BTL (Bridged TransLess) Amplifier circuit
used in the VX-4200/-4100, do not connect eather side of
the speaker leads to chassis "ground."

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, if 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 °C
and 30 °C (68 °F ~ 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 this procedure are

based on 0 dBµ EMF = 1.0 µV.

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

Band-LOW 134.100MHz
Band-MID 154.100MHz
Band-HIGH 173.900MHz

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.

The Alignment Tool Outline

Installation the tool

Install the CE59 (Clone Editor) to your PC.
The re-alignment for VX-4200/-4100 series may use the
"Alignment" menu of CE59.

Action of the switches

When the transceiver is in alignment mode, the action of
PTT and KEY is ignored. All of the action is remote con­trolled by PC.

Basic sequence

The data displayed in screen of this tool is temporary data,
and there is fear that the consistence of the displayed data
and the data in the transceiver is failure when you do not
keep the sequence which is specified below.

1. Enter the alignment mode

2. Data upload

3. Align data

4. Data download

When finish the alignment one parameter, the tool ask
you "Update this data?" If you select "Yes," the temporary
data is updated. If you select "Yes," the tool downloaded
data to the transceiver.

Menu of the Tool (BASIC ALIGNMENT

In the Basic Alignment mode, the aligned data written in
the radio will be able to re-align its alignment data. In this
mode, there are many items to align with three point (low
edge, center and high edge) except "VCO," "RX Tune" and
"Mod Balance." The value of each parameter can be
changed to desired position by "" / "" arrow key for
up/down, direct number input and drag the mouse.

To enter the Basic Alignment Mode, select "Basic Align­ment" in the main menu "Radio." It will start to "Upload"
the written personalized data from the radio and to
"Download" alignment data to the radio. Then pressing
the button "OK" will start the Basic Alignment Mode.
