Introduction
This manual provides the technical information necessary for servicing the VXR-9000 Rack Mount Repeater.
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 VXR-9000 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 CE60 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.

A-1
DSUB 25-pin Accessory Connector
The VXR-9000 repeater is provided with a 25-pin DB-25F
female connector for interconnections to accessories.Use
a DB-25M 25-pin male connector to connect accessories
to the repeater. The pins on the accessory connector are
explained in detail as follows:
DB-25 PIN NUMBERING
Pin 1: GND
Chassis ground for all logic levels and power supply return.
Pin 2: +13.6 V
[
POWER SUPPLY
This pin provides 13.6 Volts, 2.0 A, DC from the repeater
supply. There is a internal 3 A fuse to prevent damage to
the repeater.
]
Pin 3: TX AF IN
[
ANALOG TRANSMITTER INPUT] (VOICE BAND: 300 ~ 3,000 HZ
This pin is s audio input. Input impedance is 600 Ohms.
This audio is injected before the splatter filter stage, so
excess signal input levels are clipped.
Pin 5: TX ATT
This output is intended for controlling an external coaxial
switching relay. It is an open drain output which can sink
approx. 1.5 A when active. The delay time which is between the repeater cause to transmit mode and this port
switches to ground can be programmed by your VERTEX
STANDARD dealer.
Pin 6: DISC OUT
[
A
NALOG OUTPUT
Received signals with full system deviation produce 350
mVrms audio at this pin. The output impedance is 600
Ohm, and is extracted before the de-emphasis and squelch
circuitry. Use shielded cable to connect to this pin, and
connect the shield to GND.
] (
W
IDE-BAND: 0 ~ 3,000 HZ
)
Pin 7: N.C.
No connection.
Pin 8: RSSI
[
ANALOG OUTPUT]
A DC voltage proportional to the strength of the signal
currently being received (Receiver Signal Strength Indi-
cator) is provided on this pin. This low impedance output is generated by the receiver IF sub-system and buffered by an internal op-amp. Typical voltages are graphed
as follows:

Input Signal Level
Use shielded cable to connect to this pin, and connect the
shield to GND.
Pin 4: TONE IN
[
TRANSMITTER INPUT] (SUB-AUDIBLE BAND: 5 ~ 250 HZ
This pin is sub-audible tone produces 10% of full system
deviation. The nominal input voltage is 77.5 mVrms. The
input impedance is@600 Ohms, and has a flat response
characteristic (repeater deviation is constant for a given
signal level over the frequency range of 5 ~ 250 Hz). Injecting too high a voltage here causes over-deviation of
CTCSS or DCS, degrading performance. Use shielded
cable to connect to this pin, connecting the shield to GND.
)
Pin 9: COAX. SW
[
LOGIC OUTPUT (ACTIVE LOW
This output is intended for controlling an external coaxial
switching relay. It is an open drain output which can sink
approx. 1.5 A when active. This signal only switches if the
repeater has been programmed for “SIMPLEX” mode. If
programmed for “DUPLEX,” the signal remains open
(high impedance) at all time.

B-1
DSUB 25-pin Accessory Connector
Pin 10, 13, 15, 16, 17, 18, 19, 21:
PROGRAMMABLE I/O “0” ~ ”7”
The VXR-9000 provides eight ports (PIO) that can be programmed for various input or output signals, or for control functions. Each port may be programmed as to its
function, its status (input or output), and its logic (for output ports only). See Tables on the next page for detail regarding the input and output signals.
Pin 11: NSQ DET
This is an open-collector, active-low output capable of
sinking about 10 mA. It indicates that the receiver squelch
is open. If the squelch control is properly set, this indicates a carrier on the receiver channel.
Pin 12: EXT PTT
This input is internally pulled up to 5 VDC. When pulled
low by an external device, it keys the repeater transmitter
while the repeater is operating in the “Remote” mode.
Avoid voltage in excess of 5 V on this pin, or internal damage to the microprocessor on the repeater CNTL Unit may
result.
Pin 22: RXD LOW
[
ANALOG OUTPUT FOR DATA COMMUNICATIONS
(
300 ~ 3,000 Hz
)
This pin is an output for low speed receiving data signals
(typically 1200 bps), with the data being extracted after
the de-emphasis and low pass filter stages.
]
Pin 23: RXD HIGH
[
DIGITAL OUTPUT FOR DATA COMMUNICATIONS
(
Max.: 5 kHz
)
This pin is an output for high speed receiving data signals (typically 9600 bps), with the data being extracted
immediately after the discriminator (prior to any de-emphasis).
]
Pin 24: TXD LOW
[
NALOG INPUT FOR DATA COMMUNICATIONS
A
(
300 ~ 3,000 Hz
)
This pin is intended to be used as a low speed data signal
input to the repeater (typically 1200 bps). This digital data
signal is injected before the transmitter pre-emphasis and
limiting stages, so excess signal input levels are clipped.
]
Pin 14, 20: GND
Chassis ground for all logic levels and power supply return.

Circuit Description
RECEIVE SIGNAL PATH
Incoming RF from the RX antenna jack is delivered to the
MAIN Unit and passes through the protection diode
D1001 (1SS302) and a varactor-tuned band pass filter con-
sisting of coils L1003 and L1004, capacitors C1015, C1018,
C1021, C1032, and C1044, and diodes D1003 and D1004
(both HVU350). Signals are then applied to the RF amplifier, Q1009 (2SC3357). The amplified RF signal is applied
through a varactor-tuned band pass filter consisting of
coils L1010 and L1011, capacitors C1079, C1092, C1082,
C1095 and C1075, and diodes D1007 and D1005 (both
HVU350) to the first mixer Q1018 (SPM5001) along with
the first local signal from the PLL circuit.
The first local signal is generated between 376.65 MHz
and 416.65 MHz by the RX VCO, which consists of FET
Q1048 (2SK508) and varactor diodes D1018 and D1019
(both 1SV282) or FET Q1049 (2SK508) and varactor diodes D1020 and D1021 (both 1SV282), according to the
programmed receiving frequency; the local signal then
passes through buffer amplifier Q1059 (2SC5226) and
first local amplifier Q1019 (2SC3357) to the first mixer
Q1018 (SPM5001).
The 73.35 MHz first IF signal is applied to monolithic crystal filters XF1001 and XF1002 which strip away unwanted mixer products, and the IF signal is applied to the first
IF amplifiers Q1022 (2SC5226). The amplified first IF sig-
nal is then delivered to the FM IF subsystem IC Q1028
(TA31136FN), which contains the second mixer, second
local oscillator, limiter amplifier, noise amplifier, and FM
detector.
The second local oscillator signal, generated by the 72.895
MHz crystal X1002, produces the 455 kHz second IF signal when mixed with the first IF signal within Q1028
(TA31136FN). The second IF signal passes through ceramic filter CF1001 or CF1002 which strips away all but
the desired signal, and then passes through the limiter
amplifier within Q1028 (TA31136FN) to ceramic discrim-
inator CD1001, which removes any amplitude variations
in the 455 kHz IF signal before detection of speech. The
detected audio passes through the low pass filter, consisting of R1199 and C1244, which rejects the 455 kHz IF
component.
The audio signal from the MAIN Unit is delivered to the
CNTL Unit and passes through the audio amplifier Q1020
(NJM2904V) to the active high pass filter section of Q3020
(FX805LG), which rejects the sub-audible frequency component. The filtered audio signal is delivered to electronic volume Q1056, which adjusts the audio sensitivity to
compensate for audio level variations, then passes through
audio amplifier Q1020 (NJM2904V), audio switch Q1040
(BU4066BCFV), attenuator consisting of R1233, and limiter amplifier Q1050 (NJM2904V), to the electronic vol-
ume control Q1056 (M51132FP), where the maximum deviation is set. The audio signal subsequently passes
through the 3-section active low pass filter consisting of
Q1017-1/-2/-3 (NJM2902V) and audio amplifier Q1001
(NJM2902V) to providing the repeater transmit audio.
A portion of the audio signal from the active high pass
filter section of Q4024 (NJM2902V) is de-emphasized con-
sisting of Q3036 (TA75S01F), R3198, and C3144, provid-
ing a flat audio response. The filtered audio then passes
through the active band pass filter Q3021 (NJM2902V)
and audio mute gate Q3015 (DTC323TK) to audio power
amplifier Q1057 (TDA2003), providing up to 2 Watts of
audio power to the 8 Ohm loudspeaker.
SUB-AUDIBLE SIGNALING (DECODER
A portion of the audio signal from the audio amplifier
Q1020 (NJM2904V) passes through the 3-section active
low pass filter Q1025 (NJM2902V) and the low pass fil-
tering section of Q3020 (FX805LG) to separate the CTCSS tones from the received audio signal. The CTCSS tones
are sent to the CTCSS decoder section of Q3020
(FX805LG). When a CTCSS tone is received, the CTCSS
information is delivered to pin 77 of the Main CPU Q3014
(HD64F2238) from pin 4 and 8 of Q3020 (FX805LG) which
compares the CTCSS tone with the programmed tone.
Another portion of the audio signal passes through the 3section active low pass filter Q3044 (NJM2902V) to separate the DCS codes from the received audio signal. The
low pass filtered signal passes through the phase detector Q3044 (NJM2902V) to pin 39 of the Main CPU Q3014
(HD64F2238). When a DCS code is received, the Main
CPU Q3014 (HD64F2238) compares the DCS code with
the programmed code.
If the received CTCSS tone or DCS code matches the programmed tone or code, pin 4 of the Main CPU Q3014
(HD64F2238) goes low, turning off the squelch switch
Q3015 (DTC323TK) and passing the received audio sig-
nal to the audio power amplifier Q1057 (TDA2003V).
)
SQUELCH CONTROL
The squelch circuit consists of noise amplifier Q1033
(2SC4116GR) and noise detector D1015 (MA143) on the
MAIN Unit, and control circuitry within Main CPU Q3014
(HD64F2238) on the CNTL Unit.
When no carrier is received, noise at the output of the audio detector stage of Q1028 (TA31136FN) is amplified by
Q1033 (2SC4116GR), and then rectified by D1015
(MA143) to provide a DC control voltage for the squelch
switch. The resulting DC voltage is delivered to pin 23 of
J1005.
The DC voltage from the MAIN Unit is delivered to the
A-D analog input port (pin 51) of the Main CPU Q3014

(HD64F2238) on the CNTL Unit, which compares the
squelch threshold level to that which is memorized in EEPROM Q3006 (BR24L32F) or set by the front panel SQL
control.
RX PLL AND VCO CIRCUITS
The receiver’s PLL circuitry consists of PLL subsystem IC
Q1052 (MB15A02PFV1) on the MAIN Unit, which con-
tains a reference oscillator/divider, serial-to-parallel data
latch, programmable divider, phase comparator and a
swallow counter. Stability is obtained by a regulated 5
VDC supply via Q1062 (L78M05T) and temperature com-
pensated 14.4 MHz crystal oscillator X1003.
The RX VCO made up two VCO circuit, one is Low-Band
RX VCO, consisting of FET Q1048 (2SK508) and varactor
diodes D1018 and D1019 (both 1SV282), and another one
is High-Band RX VCO, consisting of FET Q1049 (2SK508)
and varactor diodes D1020 and D1021 (both 1SV282), oscillates between 376.65 MHz and 416.65 MHz according to
the programmed receiving frequency. The RX VCO output passes through buffer amplifier Q1059 (2SC5226) and
first local amplifier Q1019 (2SC3357) to the first mixer
Q1018 (SPM5001), as described previously. A portion of
the RX VCO output is applied to the prescaler/swallow
counter section in the PLL IC Q1052 (MB15A02PFV1).
There the RX VCO signal is divided by 64 or 65, according
to a control signal from the Main CPU Q3014 (HD64F2238)
on the CNTL Unit, before being applied to the programmable divider section of the PLL IC Q1052
(MB15A02PFV1).
The data latch section of the PLL IC Q1052
(MB15A02PFV1) also receives serial dividing data from
the Main CPU Q3014 (HD64F2238), which causes the predivided RX VCO signal to be further divided by 75,330 ~
81,330 (or 60,264 ~ 65,064) in the programmable divider
section in the PLL IC Q1052 (MB15A02PFV1), depend-
ing upon the desired receive frequency, so as to produce
a 5 kHz (or 6.25 kHz) derivative of the current RX VCO
frequency. Meanwhile, the reference divider section of the
PLL IC Q1052 (MB15A02PFV1) divides the 14.4 MHz
crystal reference from the reference oscillator X1003 and
Q1045 (2SC4116GR) by 2880 (or 2304) to produce the 5
kHz (or 6.25 kHz) loop reference.
The 5 kHz or 6.25 kHz signal from the programmable divider (derived from the RX VCO) and that derived from
the crystal are applied to the phase detector section of the
PLL IC Q1052 (MB15A02PFV1), which produces a pulsed
output with pulse duration depending on the phase difference between the input signals. This pulse train is then
converted to DC, low pass filtered, then fed back to the
RX VCO varactor diodes D1018/D1019 and D1020/D1021
(all 1SV282).
Changes in the DC voltage applied to the varactor diodes
D1018/D1019 and D1020/D1021 (all 1SV282) affect the
reactance in the tank circuit RX VCO Q1048/1049 (both
2SK508), changing the oscillating frequency according
to the phase difference between the signals derived from
the RX VCO and the crystal reference oscillator. The RX
VCO is thus phase-locked to the reference frequency standard.
TRANSMIT SIGNAL PATH
The speech audio from the CNTL Unit is applied to the
varactor diode D1010 (HVU350), which frequency mod-
ulates the TX VCO from the unmodulated carrier at the
transmit frequency. The modulated transmit signal is buffered by Q1026 (2SC5226), then passes through the RF
amplifier Q1030 (2SC3357) and RF diode switch D1016
(RN739F) to the PA Unit.
The transmit signal is applied to the RF amplifier Q5001
(2SC3357) and Q5008 (PD55008), then finally amplified
by power amplifier Q5015 and Q5016 (both PD55025S)
up to 50 Watts. Harmonic and spurious radiation in the
final output is suppressed by a low pass filter consisting
of coils L5007 ~ L5010, plus capacitors C5071, C5078,
C5082, C5085, and C5088 on the PA Unit, before delivery
to the TX antenna jack.
TX PLL AND VCO CIRCUITS
The Transmitter’s PLL circuitry consists of PLL subsystem
IC Q1008 (MB15A02PFV1) on the MAIN Unit, which contains a reference oscillator/divider, serial-to-parallel data
latch, programmable divider, phase comparator and a
swallow counter. Stability is obtained by a regulated 5
VDC supply via Q1062 (L78M05T) and temperature com-
pensated 14.4 MHz crystal oscillator X1001.
The TX VCO, consisting of FET Q1021 (2SK508) and var-
actor diodes D1008 and D1009 (both 1SV282), oscillates
between 450 MHz and 490 MHz according to the programmed transmit frequency. The theory of operation of
the remainder of the PLL circuitry is similar to that of the
RX PLL circuit; however, dividing data from the Main
CPU Q3014 (HD64F2238) on the CNTL Unit is such that
the VCO frequency is the actual transmit frequency.
APC (AUTOMATIC POWER CONTROL
RF power output from the final amplifier Q5015/Q5016
(both PD55025S) is sampled by C5061/C5056 and is then
rectified by D5007 and D5008 (both HSM88AS). The resulting DC voltage is applied to the comparator Q5005
(TA75S01F), where the voltage is compared with a reference voltage from the Main CPU Q3014 (HD64F2238) on
the CNTL Unit, to produce a control voltage for the Automatic Power Controller Q5004 (2SC4116GR) and
)
F-2
Q5002 (2SB1122S), which regulates supply voltage to
Q5001 (2SC3357).
)
CNTL (CONTROL
The CNTL Unit consists of 8-bit CPU Q3014 (HD64F2238),
EEPROM Q3006 (BR24L32F), RX and TX speech audio
circuits, and various analog switches for the CPU and repeater interconnections.
Microprocessor operational code is stored in Q3006
(BR24L32F), while channel data and repeater configuration information is programmed from an external PC connected to the front panel’s MIC jack via a VPL-1 programming cable.
The output from the Main CPU Q3014 (HD64F2238) con-
tains serial control data used for REPEATER/BASE mode
control, as well as TX and RX PLL data. Crystal X3002
oscillates at 12.288 MHz, and provides stable clock timing for the Main CPU. When the repeater is powered on,
the voltage at pin 62 of Q3014 (HD64F2238) becomes sta-
ble, and the output of voltage detector IC Q3012
(BD4845FVE), which is tied to pin 59 (RST) of Q3014
(HD64F2238) becomes high, resetting the Main CPU.

Alignment
Introduction
The VXR-9000 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.
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.
