VXA-300
Service Manual
Introduction
This manual provides technical information necessary for
servicing the VXA-300 Air Band Transceiver.
Servicing this equipment requires expertise in handling sur-
face-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 (trim-
mers, coils, electrolytic capacitors, ICs, etc.), or leaded com-
ponents only.
While we believe the technical information in this manual
to be correct, Vertex Standard assumes no liability for dam-
age 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
Receive Signal Path
Incoming RF from the antenna jack is passed through a
low-pass filter and high-pass filter consisting of coils
L1022, L1025, L1026, L1027, L1028, & L1029, capacitors
C1271, C1276, C1277, C1278, C1280, C1281, C1282, C1283,
C1285, C1286, C1289, C1290, C1293, C1294, & C1295 and
antenna switching diodes D1039 and D1042 (both
RLS135) to the receiver front end section.
Signals within the frequency range of the transceiver is
applied to the receiver front end which contains RF am-
plifier Q1076 (2SC5555ZD) and varactor-tuned band-pass
filter consisting of coils L1014, L1017, L1018, L1019, L1023,
L1024, & L1031, capacitors C1241, C1243, C1245, C1246,
C1248, C1250, C1255, C1256, C1259, C1266, C1272, &
C1273, and diodes D1034, D1035, D1038, & D1041 (all
HVC350B), then applied to the 1st mixer Q1068
(2SC5555ZD).
Buffered output from the VCO is amplified by Q1049
(2SC5555ZD) to provide a pure 1st local signal between
143.4 and 172.4 MHz for injection to the 1st mixer. The
35.4 MHz 1st mixer product then passes through mono-
lithic crystal filter XF1001 (7.5 kHz BW) which strips away
all but the desired signal, which is then amplified by mix-
er post-amp Q1061 (2SC4915Y).
The amplified 1st IF signal is applied to the AM/FM IF
subsystem IC Q1058 (TK10931VT1), which contains the
2nd mixer, 2nd local oscillator, limiter amplifier, noise
amplifier and AM/FM detector.
A 2nd local signal is generated by PLL IC Q1041
(MB15A01PFV1) from the 17.475 MHz crystal X1002.
The17.475MHz signal is doubled by Q1054 (2SC4617) to
produce the 450 kHz 2nd IF when mixed with the 1st IF
signal within Q1058 (TK10931VT1). The 2nd IF then pass-
es through the ceramic filter CF1001 to strip away unwant-
ed mixer products.
In the FM mode, a 2nd IF signal from the ceramic filter
CF1001 applied to the limiter amplifier section of Q1058
(TK10931VT1), which removes amplitude variations in
the 450 kHz IF before detection of the speech by the ce-
ramic discriminator CD1001. Detected audio from Q1058
(TK10931VT1) is passed through the de-emphasis, con-
sisting of the resistors R1144, R1152, R1155, & R1199, ca-
pacitors C1118, C1119, C1124, C1149, & C1151, and Q1037-
2(NJM12904R).
In the AM mode, detected audio from Q1058
(TK10931VT1) is passed through the audio amplifier
Q1037-1 (NJM12904R) and ANL circuit, then applied to
the AF amplifier Q1037-2 (NJM12904R). When impulse
noise received, a portion of the AM detector output sig-
nal from the AM/FM IF subsystem Q1058 (TK10931VT1),
including pulse noise is rectified by D1019 (1SS400). The
resulting DC is applied to the ANL MUTE gate Q1039
(UMG2N), thus reducing the pulse noises.
The processed audio signal from Q1037-1 (NJM12904R)
is passed through the AF mute and amplifier Q1037-2
(NJM12904R) to the audio tone equalizer Q1021
(NJM12904R), Q1018 (HN1J02FU), Q1023 (HN1J02FU),
Q1026 (HN1J02FU), and Q1020 (NJM12904R). The equal-
ized audio signal is passed through the volume control to
the audio power amplifier Q1001 (TDA2822D013TR), pro-
viding up to 0.8 Watts to 16-ohm loudspeaker or audio
power amplifier Q1005 (TDA7233D), providing up to 0.4
Watts to 8-ohm the headphone jack.
A portion of the AF signal from the AM/FM IF subsystem
Q1058 (TK10931VT1) converted into DC voltage within
the IC, and then passes through the AGC amplifier Q1063
(2SA1774) and Q1066 (UMW1) to the inversion amplifi-
ers Q1075 (2SC5555ZD) and Q1062 (2SC5555ZD). These
amplifier reduce the amplifier gain of the IF amplifier
Q1061 (2SC4915Y) and the RF amplifier Q1076
(2SC5555ZD) while receiving a strong signal.
Squelch Control
When signal is received, appear the DC squelch control
voltage at pin 15 of AM/FM IF subsystem Q1058
(TK10931VT1) according to the receiving signal strength.
This DC is applied to pin 16 of microprocessor Q1024
(LC87F74C8A).
The DC squelch control voltage is compared with the SQL
threshold level by the microprocessor Q1024
(LC87F74C8A). If the DC squelch control voltage is low-
er, pin 7 of Q1024 (LC87F74C8A) goes high. This signal
activates the AF MUTE gate Q1037-2 (NJM12904R), thus
disabling the AF audio.
Also, the microprocessor stops scanning, if active, and
allows audio to pass through the AF MUTE gate Q1037-2
(NJM12904R).

Transmit Signal Path
Speech input from the microphone is passed through the
microphone amplifier Q1011-1 (NJM12902V), then ap-
plied to the ALC amplifier Q1017 (AN6123MS). The am-
plified speech signal is passed through the high-pass fil-
ter Q1011-3 (NJM12902V) and low-pass filter Q1011-4
(NJM12902V), which adjust the modulation level, then
fed to the AM modulator Q1069 (2SC5555ZD).
When using the optional headset, the SIDETONE signal
from J1002 becomes “HIGH”, turning Pin10 of Q1024
(LC87F74C8A) on; pin 91 of Q1024 (LC87F74C8A) there-
fore a portion of the speech signal applied to the AF pow-
er amplifier Q1005 (TDA2733D) as a monitor signal.
The carrier signal from the VCO Q1046 (2SC5555ZD)
passes through the buffer amplifier Q1049 (2SC5555ZD)
and TX/RX switch D1026 (DAN222).
The signal from D1026 (DAN222) is amplified by Q1060
(2SC5555ZD) and Q1064 (RD01MUS1), and ultimately
applied to the final amplifier Q1069 (RD07MVS1) which
increases the signal level up to 5 watts output power. The
transmit signal then passes through the antenna switch
D1039 (RLS135), and is low-pass filtered to suppress away
harmonic spurious radiation before delivery to the anten-
na.
Automatic Transmit Power Control
RF power output from the final amplifier is sampled by
C1275/C1279 and is rectified by D1043 (HSM88WA). The
resulting DC is fed through the Automatic Power Con-
troller Q1074 (NJM2125F), thus allowing control of the
power output.
Transmit Inhibit
When the transmit PLL is unlocked, pin 7 of PLL chip
Q1041 (MB15A01PFV1) goes to a logic low. The result-
ing DC “unlock” control voltage is switches off TX inhibit
switches Q1053 (DTC144EE), and Q1055 (DTA143EE) to
disable the supply voltage to transmitter RF amplifiers
Q1060 (2SC5555ZD), disabling the transmitter.
Spurious Suppression
Generation of spurious products by the transmitter is min-
imized by the fundamental carrier frequency being equal
to the final transmitting frequency. Additional harmonic
suppression is provided by a low-pass filter consisting of
L1025, L1027 & L1029 and C1271, C1280, C1282, C1285,
C1289 & C1293, resulting in more than 60 dB of harmonic
suppression prior to delivery of the RF signal to the an-
tenna.
Circuit Description
PLL Frequency Synthesizer
PLL circuitry consists of VCO Q1046 (2SC5555ZD), VCO
buffer Q1049 & Q1051(both 2SC5555ZD), and PLL sub-
system IC Q1041 (MB15A01PFV1), which contains a ref-
erence divider, serial-to-parallel data latch, programma-
ble divider, phase comparator and charge pump.
Stability is maintained by a regulated 3.5 V supply via
Q1048 (S-812C35AUA) which feeds the PLL reference
oscillator Q1041 (MB15A01PFV1), as well as capacitors
associated with the 17.475 MHz frequency reference crys-
tal X1002.
In the receive mode, VCO Q1046 (2SC5555ZD) oscillates
between 143.4 and 172.4 MHz. The VCO output is buff-
ered by Q1049 & Q1051(both 2SC5555ZD), and applied
to the prescaler section of Q1041 (MB15A01PFV1). There
the VCO signal is divided by 64 or 65, according to a con-
trol signal from the data latch section of Q1041
(MB15A01PFV1), before being applied to the program-
mable divider section of Q1041 (MB15A01PFV1). The data
latch section of Q1041 (MB15A01PFV1) also receives se-
rial dividing data from the microprocessor Q1024
(LC87F74C8A), which causes the pre-divided VCO sig-
nal to be further divided in the programmable divider
section, depending upon the desired receive frequency,
so as to produce a 5 kHz derivative of the current VCO
frequency.
Meanwhile, the reference divider section of Q1041
(MB15A01PFV1) divides the 17.475 MHz crystal reference
from the reference oscillator section by 3495 to produce
the 5 kHz loop reference. The 5 kHz signal from the pro-
grammable divider (derived from the VCO) and that de-
rived from the reference oscillator are applied to the phase
detector section of Q1041 (MB15A01PFV1), which pro-
duces a pulsed output with pulse duration depending on
the phase difference between the input signals. This pulse
train is filtered to DC and returned to the varactor D1014
(HVC350B).
Changes in the level of the DC voltage applied to the var-
actors affect the reactance in the tank circuit of the VCO,
changing the oscillating frequency of the VCO according
to the phase difference between the signals derived from
the VCO and the crystal reference oscillator. The VCO is
thus phase-locked to the crystal reference oscillator.
The output of the VCO Q1046 (2SC5555ZD) is buffered
by Q1049 (2SC5555ZD) before application to the 1st mix-
er, as described previously.

Circuit Description
For transmission, the VCO Q1046 (2SC5555ZD) oscillates
between 118 and 137 MHz. The remainder of the PLL cir-
cuitry is shared with the receiver. However, the dividing
data from the microprocessor is such that the VCO fre-
quency is at the actual transmit frequency (rather than
offset for IFs, as in the receiving case).
Receive and transmit buses select which VCO is made
active by Q1038 (DTC144EE).
Q1077 (2SA1774) and Q1078 (UMW1) amplify the Tune
voltage for application to the tracking band-pass filters in
the receiver front end.
When the power saving feature is active, the micropro-
cessor periodically signals to the PLL IC Q1041
(MB15A01PFV1) to conserve power, and to shorten lock-
up time.
Push-To-Talk Transmit Activation
The PTT switch on the microphone is control to pin 22 of
microprocessor Q1024 (LC87F74C8A), so that when the
PTT switch is closed, pin 31 of Q1024 (LC87F74C8A) goes
high. This signals cut off the receiver by disabling the 5 V
supply bus at Q1034 (DTA143EE) which feeds the front-
end, AM/FM IF subsystem IC Q1058 (TK10931VT1), and
receiver VCO circuitry. At the same time, Q1055
(DTA143EE) and Q1053 (DTC144EE) activates the trans-
mit 5 V supply line to enable the transmitter.

Alignment
Introduction
The VXA-300 is carefully aligned at the factory for the
specified performance across the Aircraft and Weather
bands. Realignment should therefore not be necessary
except in the event of a component failure.
The following procedures cover the adjustments that are
not normally required once the transceiver has left the
factory. However, if damage occurs and some parts sub-
sequently are replaced, realignment may be required. If a
sudden problem occurs during normal operation, it is like-
ly 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 au-
thorized Vertex Standard service technicians who are ex-
perienced with the circuitry and fully equipped for repair
and alignment. If a fault is suspected, contact the dealer
from whom the transceiver was purchased for instructions
regarding repair. 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 deter-
mined to be absolutely necessary. Problems caused by
unauthorized attempts at realignment are not covered by
the warranty policy
Vertex Standard reserves the right to change circuits and
alignment procedures, in the interest of improved perfor-
mance, without notifying owners.
The following test equipment (and familiarity with its use)
is necessary for complete realignment. While most steps
do not require all of the equipment listed, the interactions
of some adjustments may require that more complex ad-
justments be performed afterwards. Do not attempt to
perform only a signal step unless it is clearly isolated elec-
trically from all other steps. Have all test equipment ready
before beginning, and follow all of the steps in a section
in the order presented.
Correction of problems caused by misalignment result-
ing from use of improper test equipment is not covered
under the warranty policy.
Required Test Equipment
Avionics Radio Tester with calibrated output level at
200 MHz
In-line Wattmeter with 5 % accuracy at 200 MHz
50-ohm, 10 W RF Dummy Load
Regulated DC Power Supply adjustable from 3 to 15
VDC, 2 A
Frequency Counter: ±0.2 ppm accuracy at 200 MHz
AF Signal Generator
AC Voltmeter
DC Voltmeter: high impedance
VHF Sampling Coupler
Alignment Preparation & Precautions
A 50-ohm RF load and in-line wattmeter must be connect-
ed 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 complet-
ing one step, read the next step to see if the same test equip-
ment is required. If not, remove the test equipment (ex-
cept 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 -
30 °C (68 - 86 °F). When the transceiver is brought into the
shop from hot or cold air, it should be allowed some time
to come to room temperature before alignment. Whenev-
er possible, alignments should be made with oscillator
shields and circuit boards firmly affixed in place. Also,
the test equipment must be thoroughly warmed up be-
fore beginning.
Set up the test equipment as shown below for transceiver
alignment, apply 7.2 VDC power to the transceiver.
Note: signal levels in dB referred to in alignment are based
on 0 dBµ = 0.5 µV (closed circuit).
