Introduction
This manual provides technical information necessary for servicing the FT-2800M FMTransceiver.
Servicing this equipment requires expertise in handling surface-mount chip components. Attempts by non-qualified per-
sons 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 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
Reception and transmission are switched by “RX” and
“TX” lines from the microprocessor unit (MPU). The re-
ceiver uses double-conversion superheterodyne circuitry,
with a 21.7 MHz 1st IF and 450 kHz 2nd IF. The 1st lo-
cal, produced by a PLL synthesizer, yields the 21.7 MHz
1st IF.
The 2nd local uses a 21.250 MHz (21.7 MHz - 450 kHz)
signal generated by a crystal oscillator. The 2nd mixer
and other circuits use a custom IC to convert and amplify
the 2nd IF, and detect FM to obtain demodulated signals.
During transmit, the PLL synthesizer oscillates at the de-
sired frequency directly, for amplification to obtain RF
power output. During transmit, voice modulation and
CTCSS (or DCS) modulation are applied to this synthe-
sizer. Transceiver functions, such as TX/RX control, PLL
synthesizer settings, and channel programming, are con-
trolled using the MPU.
Receiver
Incoming RF signals from the antenna connector are de-
livered to the RF Unit, and pass through a lowpass filter
(LPF) consisting of coils L303, L305, and L307, capaci-
tors C303, C309, C310, and C316, and antenna switching
diodes D305 and D306 (Both MA111) for delivery to the
receiver front end.
Signals within the frequency range of the transceiver are
then passed through a varactor-tuned bandpass filter con-
sisting of diodes D308, D322, D310 and D323 (all
HVC3508), and coils L334, L335, L320 and L322 and
associated circuitry before RF amplification by Q316
(3SK240).
The amplified RF signal is then bandpass filtered again
by varactor-tuned resonators consisting of diodes D312,
D324, D313 and D325 (all HVC3508), and coils L336,
L337, L325 and L327 and associated circuitry, to ensure
pure in-band input to 1st mixer Q321 (3SK240).
Buffered output from the VCO Unit is amplified by Q318
(2SC5006) and lowpass-filtered by L339, C414, and
C413, to provide a pure 1st local signal between 112.3
and 152.3 MHz, which is delivered to the 1st mixer.
The 21.7 MHz 1st mixer product then passes through dual
monolithic crystal filter F301 (7.5 kHz BW), and is am-
plified by Q327 (2SC4215Y) and delivered to the input
of the FM IF subsystem IC Q334 (TA31136FN).
This IC contains the 2nd mixer, 2nd local oscillator, lim-
iter amplifier, FM detector, noise amplifier, S-meter am-
plifier and squelch gates.
The 2nd local in the IF-IC is produced from crystal X302
(21.250 MHz), and the 1st IF is converted to 450 kHz by
the 2nd mixer and stripped of unwanted components by
ceramic filter F302. After passing through a limiter am-
plifier, the signal is demodulated by the FM detector.
Demodulated receive audio from the IF-IC is amplified
by Q336 (2SA1588Y) and Q338 (UMX2M). After vol-
ume adjustment by the AF power amplifier Q337
(LA4425A), the audio signal is passed to the optional
headphone or 8-ohm loudspeaker.
PLL Synthesizer
The 1st local maintains stability from the PLL synthesiz-
er by using a 21.250 MHz reference signal from crystal
X301. PLL synthesizer IC Q333 (LV2105V) consists of
a prescaler, reference counter, swallow counter, program-
mable counter, a serial data input port to set these counters
based on external data, a phase comparator, and a charge
pump.
The PLL-IC divides the 21.250 MHz reference signal by
4,250 using the reference counter (5.0 kHz comparison
frequency). The VCO output is divided by the prescaler,
swallow counter and programmable counter. These two
signals are compared by the phase comparator and ap-
plied to the charge pump. A voltage proportional to their
phase difference is delivered to the low-pass filter circuit,
then fed back to the VCO as a voltage with phase error,
controlling and stabilizing the oscillating frequency. This
synthesizer also operates as a modulator during transmit.
The RX VCO is comprised of Q323 (2SC5006) and
D314/D326 (Both 1SV282), and oscillates at 21.7 MHz
during receive.
The TX VCO is comprised of Q322 (2SC5006) and
D316/D327 (Both 1SV282) and oscillates at the funda-
mental frequency during transmit, with direct frequency-
modulation using varactor diode D315 (1SV214).
The VCO output passes through buffer amplifier Q320
(2SC5005), and a portion is fed to the PLL IC, and at the
same time is amplified by Q318 (2SC5006) to obtain
stable output. Synthesizer output is fed to the 1st mixer
by diode switch D311 (1SS321) during receive, and to
pri-drive amplifier Q317 (2SC3356) for transmit.
The reference oscillator feeds the PLL synthesizer, and is
composed of crystal X301 (21.250 MHz) and transmit
(DCS) modulation circuit D317 (HVC350B).
The VCO DC supply is regulated by Q330 (2SC4617).

Circuit Description
Transmitter
The speech signal from the microphone is delivered via
the MIC Jack to the RF Unit; after passing through Q315
(NJM2902V) which consists of amplifier, pre-emphasis,
limiter (IDC instantaneous deviation control) and lowpass
filter, to Q319 (M6364FP) which is adjusted for opti-
mum deviation level and delivered to the TX VCO Q322.
The speech signal from the microphone and CTCSS are
FM modulated by the TX VCO of the synthesizer, while
DCS audio is modulated by the reference frequency os-
cillator of the synthesizer.
Synthesizer output, after passing through diode switch
D311 (1SS321), is amplified by pri- drivers Q317
(2SC3356) and Q314 (RD00HVS1), driver Q313
(2SK3075), and power amplifier Q305 (RD70HVS1)
to obtain full RF output. The RF energy then passes
through antenna switch D303 (XB15A407) and a low-
pass filter circuit and finally to the antenna connector.
RF output power from the final amplifier is sampled by
C318 and C324 and is rectified by D302 (1SS321).
The resulting DC is fed through Automatic Power Con-
troller Q309 (UMT1N), Q312 (DTC114), and Q311
(2SB1197) to transmitter RF amplifier Q305 and is used
to provide control of the power output.
Generation of spurious products by the transmitter is min-
imized by the fundamental carrier frequency being equal
to the final transmitting frequency, modulated directly in
the transmit VCO.
Additionally harmonic suppression is provided by a low-
pass filter consisting of L303, L305, C303, C309, C310,
and C316, resulting in more than 60 dB of harmonic sup-
pression prior to delivery of the RF

Alignment
Introduction and Precautions
The FT-2800M has been carefully aligned at the factory
for the specified performance at the 144 MHz amateur
band. Realignment should therefore not be necessary ex-
cept 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 oper-
ation, 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 au-
thorized Vertex Standard service technicians who are ex-
perienced 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 re-
serve the right to change circuits and alignment proce-
dures in the interest of improved performance, without
notifying owners.
Under no circumstances should any alignment be attempt-
ed unless the normal function and operation of the trans-
ceiver are clearly understood, the cause of the malfunc-
tion has been clearly pinpointed and any faulty compo-
nents replaced, and the need for realignment determined
to be absolutely necessary.
Required Test Equipment
The following test equipment (and thorough familiarity
with its correct use) is necessary for complete realign-
ment. Correction of problems caused by misalignment
resulting from use of improper test equipment is not cov-
ered 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 be-
ginning, and follow all of the steps in a section in the
order presented.

rVHF Sampling Coupler
Set up the test equipment as shown for the transceiver
alignment, and apply 13.8 VDC power to the transceiver.
Alignment Preparation & Precautions
A dummy load and inline wattmeter must be connected to
the antenna jack in all procedures that call for transmis-
sion, 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 connect-
ed) before proceeding.
Correct alignment requires that the ambient temperature
in the repair shop be the same as that of the transceiver
and test equipment, and that this temperature be held con-
stant between 68 oC and 86 oF (20 oC ~ 30 oC). When
the transceiver is brought into the shop from hot or cold
air it should be allowed some time for thermal equaliza-
tion with the environment before alignment. If possible,
alignments should be made with oscillator shields and cir-
cuit boards firmly affixed in place. Also, the test equip-
ment must be thoroughly warmed up before beginning.
Notes: Signal levels in dB referred to in alignment are
based on 0 dBµ = 0.5 µV.
