Introduction
This manual provides technical information necessary for
servicing the FTM-10R/E VHF/UHF FM Transceiver.
Servicing this equipment requires expertise in handling
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 dou-
ble-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.
Important Note
The transceiver was assembled using Pb (lead) free solder, based on the RoHS specification.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this appara-
tus. The solder stated above utilizes the alloy composition required for compliance with the lead-free specification,
and any solder with the above alloy composition may be used.

Circuit Description
RECEPTION
VHF Reception
The incoming VHF signal is passed through the low-pass
filter network, antenna switching diodes and low-pass fil-
ter network to the RF amplifier Q1009 (3SK296ZQ). The
amplified RF signal is passed through the band-pass fil-
ter again by varactor-tuned resonators L1024, L1025, and
D1026 (HVC365) then applied to the 1st mixer Q1010
(3SK296ZQ) along with the first local oscillator signal
from the PLL circuit.
The first local oscillator signal, between 191.25 MHz and
195.25 MHz, is generated by the VHF VCO, which con-
sists of Q1309 (2SC5006) and varactor diodes D1310
(HVC365), D1311 (HSC277TRF), and D1312 (HVC365),
according to the receiving frequency.
UHF Reception
The incoming UHF signal is passed through the low-pass
filter network, antenna switching diodes and Low-pass
filter network to the RF amplifier Q1011 (3SK296ZQ). The
amplified RF signal is passed through the band-pass fil-
ter varactor-tuned resonators D1031 and D1032, and
D1033 (all HVC350B) then applied to the 1st mixer Q1013
(3SK296ZQ) along with the first local signal from the PLL
circuit.
The first local oscillator signal is generated between 382.75
MHz and 402.75 MHz by the UHF VCO, which consists
of Q1313 (3SK296ZQ) and varactor diodes D1314
(HSC277TRF), D1315 and D1316 (both HVC375B), ac-
cording to the receiving frequency.
IF and Audio Circuits
The 47.25 MHz first IF signal is applied to the monolithic
crystal filters XF1401 and XF1402 which strip away un-
wanted mixer products, and the IF signal is applied to
the first IF amplifier Q1407 (2SC4915). The amplified first
IF signal is then delivered to the FM IF subsystem IC
Q1408 (NJM2552V-TE1), which contains the second mix-
er, limiter amplifier, noise amplifier, and FM detector.
The second local oscillator signal is generated by the 46.8
MHz crystal X1301 and Q1403 (2SC4915), produces the
450 KHz second IF signal when mixed with the first IF
signal within Q1408 (NJM2552V-TE1) it produces the 450
KHz second IF signal..
The 450 KHz second IF signal is applied to the ceramic
filter CF1402, which strips away unwanted mixer prod-
ucts. The limiter amplifier within Q1408 (NJM2552V-TE1)
removes the amplitude variations of the 450 KHz IF sig-
nal. Speech detection is within Q1408 and the ceramic
discriminator CD1401.
The detected audio passes through the de-emphasis net-
work, a low-pass filter consisting of Q1419 (LM2902PWR)
and associated circuitry, and then a high-pass filter con-
sisting of Q1420 (LM2904PWR) and associated circuitry.
The filtered audio signal is passed through the audio vol-
ume control IC Q1511 (M61524FP-DF0G) that adjusts the
audio sensitivity to compensate for audio level variations.
When the internal speaker is selected, the audio signal is
amplified by Q1602 (TDA1519CTH) then applied to the
internal loudspeaker. When the external speaker is select-
ed, the audio signal is amplified by Q1602 (TDA1519CTH),
and then passed through the EXT SP jack to the external
loudspeaker.
Transmit Signal Path
The speech signal from the microphone passes through
the MIC jack J1604 to AF amplifier Q1508 (LM2904PWR)
on the MAIN unit. The amplified speech signal ampli-
tude is limited by Q1509 (M62429FP 780C). The speech
signal passes through buffer amplifier Q1501
(LM2902PWR) and the low-pass filter network section of
Q1501 (LM2902PWR).
VHF Transmit Signal Path
The adjusted speech signal from Q1501 (LM2902PWR)
frequency modulates the VHF transmitting VCO, made
up of Q1309 (2SC5006) and D1312 (HVC350B).
The modulated transmit signal passes through buffer
amplifier Q1308, and Q1307 (both HSC277TRF).
The filtered transmit signal is applied to the Pre-Drive
amplifier Q1003 (2SK2596BXTL) and Drive amplifier
Q1002 (RD07MVS1), and then is finally amplified by Pow-
er amplifier Q1001 (RD70HVF1) up to 50 Watts. This three
stage power amplifier's gain is controlled by the APC cir-
cuit.
The 50 Watt RF signal passes through the high-pass filter
and low-pass filter networks, the antenna switch D1007
and D1008 (both L709CER), and another low-pass filter
network, The signal is then delivered to the ANT jack.
UHF Transmit Signal Path
The adjusted speech signal from Q1501 (LM2902PWR)
frequency modulates the UHF transmitting VFO, made
up of Q1313 (2SC5006-T1) and D1316 (HVC375B).
The modulated transmit signal passes through buffer
amplifier Q1312, Q1310 and Q1311 (all 2SC5006).
The filtered transmit signal is applied to the Pre-Drive
amplifier Q1003 (2SK2596BXTL) and Drive amplifier
Q1002 (RD07MVS1), and then finally is amplified by Pow-
er amplifier Q1001 (RD70HVF1) up to 40 Watts. This three

8FTM-10R/E Technical Supplement
Circuit Description
stage power amplifier's gain is controlled by the APC cir-
cuit.
The 40-Watts RF signal passes through the high-pass fil-
ter and low-pass filter networks, antenna switch D1014
(L709CER), another low-pass filter network, and then is
delivered to the ANT jack.
Transmit APC Circuit
A portion of the Power amplifier output is rectified by
D1009 and D1010 (UHF: D1037 and D1038) (both
MA2S72800L), then delivered to APC Q1317
(LM2904PWR), as a DC voltage which is proportional to
the output level of the power amplifier.
The APC Q1317 (LM2904PWR) is the rectified DC volt-
age from the power amplifier and the reference voltage
from the main CPU Q1813 (HD64F2266TF13), to produce
a control voltage, which regulates the supply voltage to
the Pre-Drive amplifier Q1003 (2SK2596BXTL), Drive
amplifier Q1002 (RD07MVS1-T12) and Power amplifier
Q1001 (RD70HVF1), so as to maintain stable output power
under varying antenna loading condition.
PLL
A portion of the output from the VCO Q1309 (2SC5006-
T1), or Q1313 (2SC5006-T1) passes through the program-
mable divider section of the PLL IC Q1304
(MB15A02PFV1-G-BND-EFE1), which divides it accord-
ing to the frequency data that is input from the main CPU
Q1813 (HD64F2266TF13). It is then sent to the phase com-
parator.
The 11.7 MHz frequency of the reference oscillator circuit
made up of X1301 is divided by the reference frequency
divider section of Q1304 (MB15A02PFV1-G-BND-EFE1)
into 4250 or 3400 parts to become the 5 kHz or 6.25 kHz
comparative reference frequencies, which are utilized by
the phase comparator.
The phase comparator section of Q1304 (MB15A02PFV1-
G-BND-EFE1) compares the phase between the frequen-
cy-divided oscillation frequency of the VCO circuit, and
the comparative frequency. The output is a pulse corre-
sponding to the phase difference. This pulse is integrated
by the charge pump and loop filter of Q1304
(MB15A02PFV1-G-BND-EFE1) into a control voltage
(VCV) to control the oscillation frequency of the VCOs.

9FTM-10R/E Technical Supplement
The FTM-10R/E has been carefully aligned at the fac-
tory for the specified performance across the 144 MHz
and 430 MHz amateur bands. Realignment should there-
fore not be necessary except in the event of a component
failure. All component replacement and service should
be performed only by an authorized Yaesu representa-
tive, or the warranty policy may be void.
The following procedures cover adjustments that are
not normally required once the transceiver has left the
factory. However, if damage occurs and some parts are
subsequently 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
authorized Yaesu service technicians, who are experienced
with the circuitry and fully equipped for repair and align-
ment. Therefore, if a fault is suspected, contact the dealer
from whom the transceiver was purchased for instruc-
tions regarding repair. Authorized Yaesu service techni-
cians 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 unau-
thorized attempts at realignment are not covered by the
warranty policy. Yaesu must reserve the right to change
circuits and alignment procedures in the interest of im-
proved performance, without notifying owners. Under no
circumstances should any alignment be attempted unless
the normal function and operation of the transceiver is
clearly understood, the cause of the malfunction has been
clearly pinpointed, any faulty components replaced, and
the need for realignment is determined to be absolutely
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
require that additional adjustments be performed. 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
Alignment Preparation & Precautions
A dummy load and inline 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 complet-
ing one step, read the following step to determine wheth-
er the same test equipment will be required. If not, re-
move the test equipment (except dummy load and watt-
meter, if connected) before proceeding.
Correct alignment requires that the ambient temperature
of the transceiver be the same as that of the test equip-
ment, and that the temperature be held constant between
20° and 30° C (68° ~ 86° F). When the transceiver is brought
into the shop from hot or cold air it should be allowed
some time for thermal equalization with the environment
before alignment. If possible, alignments should be made
with oscillator shields and circuit boards firmly affixed
in place. 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= 0.5 μV(closed circuit).
