Introduction
This manual provides the technical information necessary for servicing the FT-
270R/E VHF FM Transceiver.
Servicing this equipment requires expertise in handing surface-mount chip compo-
nents. 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 coun-
tries.
Two PCB layout diagrams are provided for each double-sided board in this trans-
ceiver. Each side of the board is referred to by the type of the majority of compo-
nents 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.
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
Receive Signal Path
Incoming RF signal is from the antenna jack is delivered
to the Main Unit and passed through the low-pass filter
network, antenna switching diode D1003 and D1004 (both
RLS135), and low-pass filter network to the RF amplifier
Q1022 (3SK296ZQ). The amplified RF signal is passed
through band-pass filtered again by varactor-tuned band-
pass filter consisting of coils L1024, L1025, and L1026, and
diodes D1017, D1018, and D1019 (all HVC350B), then ap-
plied to the 1st mixer Q1023 (3SK296ZQ) along with the
first local signal from the PLL circuit.
The first local signal is generated between 115.3 MHz and
152.3 MHz by the VCO, which consists of Q1014
(2SC5005)and varactor diodes D1009, D1010 (both
HVC365) and D1011 (HSC277) according to the receiv-
ing frequency.
IF and Audio Circuits
The 21.7 MHz first IF signal is applied to the monolithic
crystal filters XF1001 and XF1002 which strip away un-
wanted mixer products, and the IF signal is applied to the
first IF amplifier Q1024 (2SC4915). The amplified first IF
signal is then delivered to the FM IF subsystem IC Q1004
(NJM2591V), which contains the second mixer, limiter am-
plifier, noise amplifier, and FM detector.
The second local signal is generated by 21.25 MHz crystal
X1002, produces the 450 kHz second IF signal when mixed
with first IF signal within Q1004 (NJM2591V).
The 450 kHz second IF signal is applied to the ceramic
filter CF1001 or CF1002 which strip away unwanted mix-
er products to the ceramic discriminator CD1001 which
removes any amplitude variations in the 450 kHz IF sig-
nal before detection of speech.
The detected audio from the Q1004 (NJM2591V) is ap-
plied to a band-pass filter consisting of Q1081 and Q1082
(both 2SC4617), then passes through the audio mute gate
Q1052 (2SC4617) and Q1045 (DTC144EE).
The audio signal is passed through the audio VR which
adjusts the audio sensitivity to compensate for audio lev-
el variations, then delivered to the audio amplifier Q1008
(TDA2822D).
Squelch Control
When no carrier received, noise at the output of the de-
tector stage in Q1004 (NJM2591V) is applied to pin 49 of
main CPU Q1001 (HD64F2266TF13), which compares the
squelch threshold level to that which set by the SQL knob.
While no carrier is received, pin 71 of Q1001
(HD64F2266TF13) remains “low,” to disable audio out-
put from the speaker.
Transmit Signal Path
The speech signal from the microphone is amplified by
Q1074 (LM2902PWR). The amplified speech signal is sub-
jected to the low-pass filter network Q1074 (LM2902PWR)
and deviation controller Q1075 (DTC144EE).
VHF Transmit Signal Path
The adjusted speech signal from Q1075 (DTC144EE) is
delivered to VCO Q1014 (2SC5005) which frequency
modulates the transmitting VCO made up of D1010
(HVC365).
The modulated transmit signal passes through buffer
amplifier Q1013 and Q1012 (both 2SC5005).
The transmit signal applied to the Pre-Drive amplifier
Q1011 (2SC5005) and Drive amplifier Q1010 (2SK3074),
then finally amplified by Power amplifier Q1009
(2SK3476) up to 5 Watts. This two stages (Q1010 and
Q1009) power amplifier’s gain is controlled by the APC
circuit.
The 5 Watts RF signal passes through low-pass filter net-
work, antenna switch D1003 (RLS135), and another low-
pass filter network, and then deliver to the ANT jack.
Tx APC Circuit
A portion of the Power amplifier output is rectified by
D1002 (1SS321), then delivered to APC Q1019
(LM2904PWR), Q1020 and Q1021 (both DTC144EE), as a
DC voltage which is proportional to the output level of
the power amplifier.
The APC Q1019 (LM2904PWR) is compared the rectified
DC voltage from the power amplifier and the reference
voltage from the main CPU Q1001 (HD64F2266TF13), to
produce a control voltage, which regulates supply volt-
age to the Drive amplifier Q1010 (2SK3074) and Power
amplifier Q1009 (2SK3476), so as to maintain stable out-
put power under varying antenna loading condition.
PLL
A portion of the output from the VCO Q1014 (2SC5005),
passes through the buffer amplifier Q1017 (2SC5005), then
delivered to the programmable divider section of the PLL
IC Q1003 (MB15A01PFV1), which divided according to the
frequency dividing data that is associated with the setting
frequency input from the main CPU Q1001
(HD64F2266TF13). It is then sent to the phase comparator.
The 21.25 MHz frequency of the reference oscillator cir-
cuit made up of X1002 is divided by the reference frequen-
cy divider section of Q1003 (MB15A01PFV1) into 4250 or
3400 parts to become 5 kHz or 6.25 kHz comparative ref-
erence frequencies, which are utilized by the phase com-
parator.

8FT-270R/E Technical Supplement
Circuit Description
The phase comparator section of Q1003 (MB15A01PFV1)
compares the phase between the frequency-divided os-
cillation frequency of the VCO circuit and comparative
frequency and its output is a pulse corresponding to the
phase difference. This pulse is integrated by the charge
pump and loop filter of D1012 (DA221) and Q1016
(DTC144EE) into a control voltage (VCV) to control the
oscillation frequency of the VCO.

9FT-270R/E Technical Supplement
Alignment
Introduction
The FT-270R/E is carefully aligned at the factory for the
specified performance across the amateur band. Realign-
ment should therefore not be necessary except in the event
of a component failure. Only an authorized Vertex Stan-
dard representative should perform all component re-
placement and service, or the warranty policy may be
void.
The following procedures cover the adjustments that are
not normally required once the transceiver has left the fac-
tory. However, if damage occurs and some parts subse-
quently 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. Authorized Vertex Standard service tech-
nicians 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 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 realignment determined to be abso-
lutely necessary.
Required Test Equipment
The following test equipment (and familiarity with its
use) is necessary for complete realignment. Correction of
problems caused by misalignment resulting from use of
improper test equipment is not covered under the war-
ranty policy. While most steps do not require all of the
equipment listed, the interactions of some adjustments
may require that more complex adjustments be per-
formed 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 load and in-line wattmeter must be con-
nected to the main antenna jack in all procedures that call
for transmission; alignment is not possible with an anten-
na. After completing one step, read the next step to see if
the same test equipment is 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 68 ~
86° F (20° ~ 30° C). 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.
Whenever possible, alignments should be made with os-
cillator 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 pro-
cedure are based on 0dBμ= 0.5μV.
