144/430 MHz Dual-Band Digital Transceiver
FT2DR/DE
Introduction
This manual provides the technical information necessary for ser-
vicing the FT2DR/DE 144/430 MHz Dual Band Digital Trans-
ceiver.
Servicing this equipment requires expertise in handing 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 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, 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,
YAESU 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
This transceiver was assembled using Pb (lead) free
solder, based on the RoHS specication.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-
0.5Cu) should be used for repairs performed on this
apparatus. The solder stated above utilizes the alloy
composition required for compliance with the lead-free
specication, and any solder with the above alloy com-
position may be used.

FT2DR/DE Technical Supplement
Alignment
ALIGNMENT-1
Introduction and Precautions
The FT2DR/FT2DE has been carefully aligned at
the factory for performance across the specified
amateur bands. Realignment should therefore
not be necessary except in the event of a compo-
nent failure. All component replacement and ser-
vice should be performed only by an authorized
YAESU representative, or the warranty policy may
be voided.
The following procedures cover the sometimes crit-
ical and tedious adjustments that are not normally
required once the transceiver has left the factory.
However, if damage occurs and some parts are re-
placed, 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 alignment. Therefore, if a fault is
suspected, contact the dealer from whom the trans-
ceiver was purchased for instructions regarding re-
pair. Authorized YAESU service technicians realign
all circuits and make complete performance checks
to ensure compliance with factory specifications
aer 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 aempts at
realignment are not covered by the warranty pol-
icy. Also, YAESU must reserve the right to change
circuits and alignment procedures in the interest of
improved performance, without notifying owners.
Under no circumstances should any alignment be
attempted unless the normal function and opera-
tion of the transceiver are clearly understood, the
cause of the malfunction has been clearly pinpoint-
ed and any faulty components replaced, and the
need for realignment determined to be absolutely
necessary.
Required Test Equipment
RF Signal Generator with calibrated output level
at 500 MHz
Deviation Meter (linear detector)
 In-line Wameter with 5% accuracy at 500 MHz
50-ohm, 10-W RF Dummy Load
8-ohm AF Dummy Load
Regulated DC Power Supply adjustable from
8 to 16 V DC, 3 A
Frequency Counter: 0.2-ppm accuracy at
500 MHz
AF Signal Generator
AC Voltmeter
DC Voltmeter: high impedance
UHF Sampling Coupler
SINAD Meter
Alignment Preparation & Precautions
A 10-W RF dummy load and in-line wattmeter
must be connected to the main antenna jack in all
procedures that call for transmission; alignment
is not possible with an antenna. After complet-
ing 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 align-
ment requires the transceiver and test equipment
be maintained at a constant ambient temperature
between 68~86 °F (20~30 °C). When the transceiv-
er 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 oscillator shields
and circuit boards rmly axed in place. Also, the
test equipment must be thoroughly warmed up be-
fore beginning.
Note: Signal levels in dB referred to in the alignment
procedure are based on 0 dBμ=0.5 μV (closed circuit).
Important Notice
Do not adjust the alignment menus that are
not mentioned in this manual.

ALIGNMENT-2
Internal System Alignment Routine
This uses a programmed routine in the transceiver
which simplies many previously complex discrete
component seings and adjustments with digital-
ly-controlled settings via front panel buttons and
LCD indications.
1. To begin, set the transceiver to the VFO mode
on the "A-Band, FM-mode" in the "Mono" band
mode.
2. Program a password for the Alignment
(AH060M) according to the following proce-
dure:
1) Press and hold the [DISP]key for one second
to enter the Set mode.
2) Touch [DISPLAY] briefly to enable adjust-
ment of this Set Mode Item.
3) Rotate the DIAL knob to select Set Mode Item
8: OPENING MESSAGE.
4) Press the [DISP] key briey to enable adjust-
ment of this Set Mode Item.
5) Rotate the DIAL knob to select Set Mode Item
MESSAGE.
6) Press the [DISP] key briey to enable adjust-
ment of this Set Mode Item.
7) Input the password "AH060M" (toggle the
alphabet input screen, and the number input
screen when necessary).
8) When you have completed the password,
press the [DISP]key briefly, then press the
PTT switch to exit to normal operation.
Note: Remember to delete the password "AH060M"
from the Set Mode Item 8: OPENING MESSAGE when
the alignment adjustments are nished by pressing and
holding in the [GM] key for two seconds (as in step 8
above).
3. Press the [PWR]switch for two seconds to turn
the transceiver "o".
4. Press and hold in the [GM]key while powering
the transceiver "on" again. The transceiver will
enter the adjustment mode, and the display
will show the rst alignment seing. Thereaf-
ter, the frequencies used during alignment will
automatically be set without action by the tech-
nician.
In the alignment process, each adjustment is se-
lected by rotating the DIAL knob. The alignment
is performed by: pressing the [V/M]key injecting a
signal of the required frequency and level; making
the adjustment; and then pressing the [V/M]key
again (the "Data" will disappear from the display),
to store the adjustment.
To exit the alignment routine, press the [GM]key.
After performing the system alignment in its en-
tirety, individual settings can be returned to and
adjusted individually, should the need arise.
As each transceiver is individually optimized at
the factory, the precise seings for the transceiver
on your bench may be slightly dierent.
