Introduction
This manual provides the technical information necessary for
servicing the FT-60R VHF/UHF Dual Band Transceiver.
Servicing this equipment requires expertise in handing sur-
face-mount chip components. Attempts by non-qualified per-
sons to service this equipment may result in permanent dam-
age 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 (trim-
mers, coils, electrolytic capacitors, ICs, etc.), or leaded compo-
nents 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 inconsisten-
cies in the technical information would be appreciated.

Circuit Description
VHF Reception
Incoming VHF signal is passed through the low-pass fil-
ter network, antenna switching diode D1066 (HVC131)
and D1068 (RLS135), and low-pass filter network to the
RF amplifier Q1085 (3SK296ZQ). The amplified RF sig-
nal is passed through band-pass filtered again by varac-
tor-tuned resonators L1060, L1061 and L1062, and D1063,
D1064, and D1065 (all HVC365), then applied to the 1st
mixer Q1083 (3SK296ZQ) along with the first local signal
from the PLL circuit.
The first local signal is generated between 191.25 MHz
and 195.25 MHz by the VHF VCO, which consists of Q1067
(2SC5006), switching diodes D1034, D1035 (both
HSC277), and varactor diodes D1036, D1037 (both
HVC365) according to the receiving frequency.
UHF Reception
Incoming UHF signal is passed through the low-pass fil-
ter network, antenna switching diodes D1060 and D1082
(both HSC277), and Low-pass filter network to the RF am-
plifier Q1081 (3SK296ZQ). The amplified RF signal is
passed through band-pass filtered again by varactor-tuned
resonators L1049, L1050 and L1051, and D1054, D1055,
and D1056 (all HVC350B), then applied to the 1st mixer
Q1080 (3SK296ZQ) along with the first local signal from
the PLL circuit.
The first local signal is generated between 382.75 MHz
and 402.75 MHz by the UHF VCO, which consists of Q1065
(2SC5006) and varactor diodes D1030 (HVC375B), D1031
(HVC350B) and switching diode D1032 (HSC277) accord-
ing to the receiving frequency.
IF and Audio Circuits
The 47.25 MHz first IF signal is applied to the monolithic
crystal filters XF1001 which strip away unwanted mixer
products, and the IF signal is applied to the first IF ampli-
fier Q1049 (2SC4915). The amplified first IF signal is then
delivered to the FM IF subsystem IC Q1044 (TA31136FN),
which contains the second mixer, limiter amplifier, noise
amplifier, and FM detector.
The second local signal is generated by 46.8 MHz crystal
X1002 and Q1041 (2SC4915), produces the 450 kHz sec-
ond IF signal when mixed with first IF signal within Q1044
(TA31136FN).
The 450 kHz second IF signal is applied to the ceramic
filter CF1001 which strip away unwanted mixer products
to the ceramic discriminator CD1001 which removes any
amplitude variations in the 450 kHz IF signal before de-
tection of speech.
The detected audio passes through the de-emphasis net-
work, low-pass filter consisting of Q1007 (NJM12902V)
and associated circuitry, and high-pass filter consisting of
Q1007 (NJM12902V) and associated circuitry. The filtered
audio signal is applied to the audio volume, then passes
through the AF ampplifire Q1008 (TDA7233D) and MIC/
SP jack to the internal speaker or an external speaker.
Squelch Control
When no carrier received, noise at the output of the de-
tector stage in Q1044 (TA31136FN) is amplified and band-
pass filtered by the noise amp section of Q1044
(TA31136FN). The resulting DC voltage is applied to pin
47 of main CPU Q1031 (HD64F2266), which compares
the squelch threshold level to that which set by the SQL
knob.
While no carrier is received, pin 35 of Q1031 (HD64F2266)
remains “low,“ squelch gate Q1005 and Q1091 (both
DTC144EE) to turns off to disable any demodulated au-
dio pass.
Transmit Signal Path
The speech signal from the microphone to AF amplified
Q1019 (NJM12902V). The amplified speech signal passes
through low-pass filter network Q1019 (NJM12902V) to
deviation controlled by Q1030 (BU2090FS).
VHF Transmit Signal Path
The adjusted speech signal is delivered to VHF VCO
Q1067 (2SC5006) which frequency modulates the trans-
mitting VCO made up of D1037 (HVC365).
The modulated transmit signal passes through buffer
amplifier Q1068 and Q1070 (both 2SC5006).
The filtered transmit signal applied to the Pre-Drive am-
plifier Q1071 (2SC5006) and Drive amplifier Q1074
(2SK2596), then finally amplified by Power amplifier
Q1075 (RD07MVS1) up to 5 Watts. This two stages pow-
er amplifier's gain is controlled by the APC circuit.
The 5 Watts RF signal passes through low-pass filter net-
work, antenna switch D1050 (RLS135), and another low-
pass filter network, and then deliver to the ANT jack.
UHF Transmit Signal Path
The adjusted speech signal is delivered to UHF VCO
Q1065 (2SC5006) which frequency modulates the trans-
mitting VCO made up of D1030 (HVC375).
The modulated transmit signal passes through buffer
amplifier Q1066 and Q1069 (both 2SC5006).
The filtered transmit signal applied to the Pre-Drive am-
plifier Q1071 (2SC5006) and Drive amplifier Q1074
(2SK2596), then finally amplified by Power amplifier
Q1075 (RD07MVS1) up to 5 Watts. This two stages pow-
er amplifier's gain is controlled by the APC circuit.

Circuit Description
The 5 Watts RF signal passes through high-pass filter and
high-pass filter network, antenna switch D1044 (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
D1051 (UHF: D1046 and D1047) (all RB751S), then de-
livered to APC Q1054 (TA75S01F), as a DC voltage which
is proportional to the output level of the power amplifier.
The APC Q1054 (TA75S01F) is compared the rectified DC
voltage from the power amplifier and the reference volt-
age from the main CPU Q1031 (HD64F2266), to produce
a control voltage, which regulates supply voltage to the
Drive amplifier Q1074 (2SK2596) and Power amplifier
Q1075 (RD07MVS1), so as to maintain stable output power
under varying antenna loading condition.
PLL
A portion of the output from the VCO Q1065 (UHF:
2SC5006) and Q1067 (VHF: 2SC5006), passes through
buffer amplifier Q1066 (UHF), Q1068 (VHF), and Q1040
(all 2SC5006) programmable divider section of the PLL
IC Q1037 (MB15A01PFV1), which divided according to
the frequency dividing data that is associated with the set-
ting frequency input from the main CPU Q1031
(HD64F2266). It is then sent to the phase comparator.
The 11.7 MHz frequency of the reference oscillator circuit
made up of X1002 is divided by the reference frequency
divider section of Q1037 (MB15A01PFV1) into 2340 or
1872 parts to become 5 kHz or 6.25 kHz comparative ref-
erence frequencies, which are utilized by the phase com-
parator.
The phase comparator section of Q1037 (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 Q1037 (MB15A01PFV1) into a
control voltage (VCV) to control the oscillation frequency
of the VCOs.

Alignment
Introduction
The FT-60R is carefully aligned at the factory for the spec-
ified performance across the amateur band. Realignment
should therefore not be necessary except in the event of a
component failure. Only an authorized Vertex Standard
representative should perform all component replacement
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 prob-
lems caused by misalignment resulting from use of im-
proper test equipment is not covered under the warranty
policy. While most steps do not require all of the equip-
ment listed, the interactions of some adjustments may re-
quire that more complex adjustments be performed after-
wards.
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.
