GENERAL DESCRIPTION
Congratulations on the purchase of your Yaesu amateur
transceiver ,f this is your ¿rst rig, or if Yaesu eTuipment
is already the backbone of your station, rest assured
your transceiver will provide many hours of operating
pleasure for years to come.
The
FT
DX
1200
is an elite-class HF transceiver provid-
ing exceptional performance both on transmit and re-
ceive. The
FT
DX
1200
is designed for the most competi-
tive operating situations, whether you primarily operate
in contest, ';, or digital-mode environments.
Built on the foundation of the popular
FT
DX
9000
trans-
ceiver, and carrying on the proud tradition of the
FT-
1000
series, the
FT
DX
1200
provides up to 100 Watts
of power output on 66B, CW, and F0  Watts $0
carrier. 'igital 6ignal 3rocessing '63 is utili]ed
throughout the design, providing leading-edge transmit-
ter and receiver performance.
For exceptional protection from strong signal interfer-
ence, the optional 5F Tuning .its may be connected
via the rear panel. The 5F Tuning .its provide extraor-
dinarily sharp selectivity and protect your receiver from
close-in interference on a crowded band.
,n the front end, you may select one of two 5F pream-
pli¿ers, or ,32 ,ntercept 3oint 2ptimi]ation, providing
direct feed to the ¿rst mixer. Three levels of 5F attenua-
tion are available in 6-dB steps.
The
FT
DX
1200
receiver utili]es '63 ¿ltering, incorpo-
rating many of the features of the
FT
DX
9000
, such as
9ariable Bandwidth, ,F 6hift, and 3assband Contour
tuning. $lso provided are 'igital 1oise 5eduction, 'igi-
tal $uto-1otch Filtering and a manually tuned ,F 1otch
¿lter.
2n the transmit side, the Yaesu exclusive Three-Band
3arametric 0icrophone (Tuali]er allows precise and
flexible adjustment of the waveform created by your
voice and microphone. The audio $mplitude, Center
FreTuency, and Bandwidth are adjusted separately for
the low, mid-range, and high-freTuency audio spectrum.
The transmitted bandwidth may also be adjusted.
$dvanced features include 'irect .eyboard FreTuency
(ntry and Band Change, 6peech 3rocessor, ,F 0onitor
for 9oice modes, CW 3itch control, CW 6pot switch,
Full CW 46., CW 0essage 0emory, adjustable ,F
1oise Blanker, and all mode 6Tuelch. Two T;5;
antenna ports are provided on the rear panel. Two key
jacks are provided one on the front and one on the rear
panel
. The key jacks may be con¿gured independently
for paddle input, connection to a straight key, or com-
puter-driven keying interface.
FreTuency setup is straightforward on the
FT

1200
.
(nter freTuency directly for 9F2-$. 6eparate keys are
available for band selection. (ach band key provides
three separate 9F2 settings for three different parts of
each band. You may create three independent 9F2 set-
tings of freTuency, mode, and ¿lter for each band.
,n addition,  memories are provided to store FreTuen-
cy, 0ode, ,F ¿lter selection, Clari¿er offset, and 6can-
skip status. Whats more, five Tuick-recall “40B”

EXTENDING THE FRONT FEET
To elevate the front panel for easy viewing, the front left and right feet on the case bottom may be extended.
3ull the front legs outward from the bottom panel.
5otate the legs counter-clockwise to lock them in
the extended position. Be sure the legs have locked
securely in place, because the transceiver is Tuite
heavy and an unlocked leg could result in damage,
should the transceiver move suddenly.
Retracting the Front Feet
5otate the legs clockwise.
3ush them inward while continuing to rotate clock-
wise. The front feet should now be locked in the re-
tracted position.
ADJUSTING THE MAIN TUNING DIAL TORQUE
The torTue drag) of the 0ain Tuning 'ial knob may be
adjusted according to your preferences. 5otate the skirt
at the base of the knob clockwise to reduce the drag, or

1200 OPERATING MANUAL
ANTENNA CONSIDERATIONS
The
FT
DX
1200
is designed for use with any antenna system providing a 0 2hm resistive impedance at the desired op-
erating freTuency. While minor excursions from the 0-2hm speci¿cation are of no conseTuence, if the Standing Wave
5atio SW5) present at the $ntenna jack is greater than 31, the transceivers $utomatic $ntenna Tuner may not be able
to reduce the impedance mismatch to an acceptable value.
(very effort should be made to ensure that the impedance of the antenna system be as close as possible to the speci¿ed
0-2hm value. 1ote that the “G5V” type antenna does not provide a 0-2hm impedance on all HF $mateur bands. $n
external wide-range antenna coupler must be used with this antenna type.
$ny antenna to be used with the
FT
DX
1200
must be fed from the transceiver with 0 2hm coaxial cable. Therefore,
when using a “balanced” antenna such as a dipole, remember that a balun or other matchingbalancing device must be
used to ensure proper antenna performance.
The same precautions apply to any additional receive-only) antennas connected to the antenna jacks. if your receive-
only antennas do not have impedance near 0 2hms at the operating freTuency, you may need to install an external an-
tenna tuner to obtain optimum performance.
ABOUT COAXIAL CABLE
Use high-Tuality 0-2hm coaxial cable for the lead-in to your
FT
DX
1200
transceiver. $ll efforts at providing an ef-
¿cient antenna system will be wasted if poor Tuality, lossy coaxial cable is used. This transceiver utili]es standard “0”
“3L-”) type connectors.

GROUNDING
The
FT
DX
1200
transceiver, like any other HF communications apparatus, reTuires an effective ground system for maxi-
mum electrical safety and best communications effectiveness. $ good ground system can contribute to station ef¿ciency
in a number of ways
It can minimi]e the possibility of electrical shock to the operator.
It can minimi]e 5F currents Àowing on the shield of the coaxial cable and the chassis of the transceiver. such cur-
rents may lead to radiation, which can cause interference to home entertainment devices or laboratory test eTuip-
ment.
It can minimi]e the possibility of erratic transceiveraccessory operation caused by 5F feedback andor improper
current Àow through logic devices.
$n effective earth ground system may take several forms. for a more complete discussion, see an appropriate 5F engi-
neering text. The information below is intended only as a guideline.
Typically, the ground connection consists of one or more copper-clad steel rods, driven into the ground. If multiple
ground rods are used, they should be positioned in a “V” con¿guration and bonded together at the base of the “V” which
is nearest the station location. Use a heavy, braided cable such as the discarded shield from type 5G-13 coaxial cable)
and strong cable clamps to secure the braided cables) to the ground rods. Be sure to weatherproof the connections
to ensure many years of reliable service. Use the same type of heavy, braided cable for the connections to the station
ground bus described below).
Inside the station, a common ground bus consisting of a copper pipe of at least  mm diameter should be used. $n al-
ternative station ground bus may consist of a wide copper plate single-sided circuit board material is ideal) secured to
the bottom of the operating desk. Grounding connections from individual transceivers, power supplies, and data com-
munications devices T1Cs, etc.) should be made directly to the ground bus using a heavy, braided cable.
'o not “'aisy-Chain” ground connections from one electrical device to another and thence to the ground bus. This
method may nullify any attempt at effective radio freTuency grounding. See the drawing below for examples of proper
grounding techniTues.
Inspect the ground system - inside the station as well as outside - on a regular basis to ensure continued performance
and safety.
Besides following the above guidelines carefully, note that household or industrial gas lines must never be used in an
attempt to establish an electrical ground. Cold water pipes may, in some instances, help in the grounding effort, but gas
lines represent a signi¿cant explosion ha]ard, and must never be used.

1200 OPERATING MANUAL
CONNECTION OF ANTENNA AND POWER CABLES
3lease follow the outline in the illustration regarding the proper connection of antenna coaxial cables, as well as the 'C
power cable. The 'C power connector for the
FT
DX
1200
must only be connected to a 'C source providing 13.8 Volts 'C
10 ), and capable of at least 3 $mperes of current. $lways observe proper polarity when making 'C connection
The RED DC power lead connects to the Positive (+) DC terminal.
The BLACK DC power lead connects to the Negative (–) DC terminal.
We recommend the use of the
FP-1030A
US$ market only) $C 3ower Supply. 2ther models of power supplies may
be used with the
FT
DX
1200
, but the 13.8 V'C input voltage, 3 $mpere current capability, and 'C cable polarity
guidelines described above must be strictly followed.
1ote that other manufacturers may use the same type of 'C power connections as does your
FT
DX
1200
transceiver,
however, the wiring con¿guration may be different from that speci¿ed for your transceiver. Serious damage can be
caused if improper 'C connections are made consult with a Tuali¿ed service technician when in doubt.
The 100 V 5F voltage #100 W0-ohm) is applied to the T; 5F section of the transceiver while transmitting.
'o not touch the T; 5F section absolutely while transmitting.
3ermanent damage can result when improper supply voltage, or reverse-polarity voltage, is applied to the
FT
DX
1200
. The Limited Warranty on this transceiver does not cover damage caused by application of $C volt-
age, reverse polarity 'C, or 'C voltage outside the speci¿ed range of 13.8 V 10 . When replacing fuses, be certain
to use a fuse of the proper rating. The
FT
DX
1200
reTuires a  $ blade fuse.
ADVICE:
'o not position the
FT
DX
1200
in a location with direct exposure to sunshine.
'o not position the
FT
DX
1200
in a location exposed to dust andor high humidity.
(nsure adeTuate ventilation around the
FT
DX
1200
, to prevent heat build-up and possible reduction of performance
due to high heat.
'o not install the
FT
DX
1200
on an unstable desk or table. 'o not place in a location where objects may fall onto it from above.
To minimi]e the possibility of interference to home entertainment devices, take all precautionary steps including
separation of TVF0 antennas from $mateur transmitting antennas to the greatest extent possible, and keep trans-
mitting coaxial cables separated from cables connected to home entertainment devices.
(nsure that the 'C power cord is not subject to undue stress or bending, which could damage the cable or cause it to
be accidentally unplugged from the rear panel
DC IN
jack.
Be certain to install your transmitting antennas) so they cannot possibly come in contact with TVF0 radio or other
antennas, or with power or telephone lines.
INSTALLATION AND INTERCONNECTIONS
To prevent damage from
lightning, atmospheric elec-
tricity, electrical shock etc., please
provide a good earth ground.
Use a short,
thick, braided
cable to con-
nect your station
eTuipment to the
buried ground rod or alternative earth
ground system).
Check the DC volt-

The

1200
includes many features for the CW operator. These functions will be detailed in the “2peration” section
later. Besides the built-in (lectronic .eyer, two key jacks are provided, one on the front and one on the rear panel, for
convenient connection to keying devices.
The 0enu selections allow you to con¿gure the front and rear panel
KEY
jacks according to the device you wish to con-
nect. For example, you may connect your keyer paddle to the front panel
KEY
jack, and use 0enu item “
018 F KEYER
TYPE
” for paddle input, and also connect the keying line from your personal computer which emulates a “straight key”)
to the rear panel
KEY
jack, and con¿gure the rear panel jack using 0enu item “
020 R KEYER TYPE
”.
Both
KEY
jacks on the
FT
DX
1200
utili]e “3ositive” keying voltage. .ey-up voltage is approximately 3.3V 'C, and
key-down current is approximately 4 m$. When connecting a key or other device to the
KEY
jacks, use only a 3-con-
tact “stereo”) 14” phone plug a -contact plug will place a short between the ring and grounded) shaft of the plug,
resulting in a constant “key-down” condition in some circumstances.

INTERFACING TO OTHER LINEAR AMPLIFIERS
NOTE
The T; G1' 2UT pin pin ) of the
LINEAR
jack
is a transistor “open collector” circuit. It is capable of
handling positive relay coil voltages up to 30 V'C
at 00 m$. If you plan to use multiple linear ampli-
¿ers for different bands, you must provide external
band switching of the “Linear Tx” relay control line
from the “T; G1' 2UT” line at the
LINEAR
jack.
The speci¿ed range for $LC voltage to be used with
the
FT
DX
1200
is 0 to -4 Volts 'C.
$mpli¿er systems utili]ing different $LC voltages
will not work correctly with the
FT
DX

, and
their $LC lines must not be connected if this is the
case.
IMPORTANT NOTE!
'o not exceed the maximum voltage or current rat-
ings for the “T; G1' 2UT” pin pin ) of the
LIN-
EAR
jack. This line is not compatible with negative
'C voltages, or $C voltages of any magnitude.

(
REQUIRES THE OPTIONAL RF μ TUNING KIT
)
The 5F Tuning .it provides ultra-sharp 5F selectivity for the front end of the transceiver. Very high Q is made pos-
sible by the narrow-band design. Three 5F Tuning .its are available. The
MTU-160
covers the 1.8 0H] band. The
MTU-80/40
covers the 3. and 7 0H] bands. The
MTU-30/20
covers 10.1 and 14 0H] bands.
When any or all) of the three optional units are connected, they will be automatically adjusted to center on your operat-
ing freTuency.
The narrow bandwidth is especially useful on the low bands, when many strong signals are being received via 1VIS
propagation 1ear Vertical-Incidence Signals) within a narrow bandwidth. The added protection for the 5F stage is es-
pecially helpful in preventing I0' and blocking.

crowded bands on a contest weekend. The -Tune
¿lters provide 5F selectivity on the order of a few

system gain on bands where noise ¿gure is seldom
an issue. You will notice that the S-meter deÀection,
when -Tune is engaged, is slightly less than when
it is out of the circuit this is normal. If your antenna
system gain is so low that you cannot hear the band
noise when -Tune is engaged highly unlikely), just
switch it out, to eliminate the slight insertion loss.

ADVICE:
$LC meter deÀection may be caused by excessive
drive power, but also by reÀected power detected in
the antenna system. If the impedance presented to
the transceiver is other than 0 2hms, $LC meter ac-
tion may be observed that is not related to the proper
setting of the
[
MIC/SPEED
]
knob. Therefore, we
recommend that you make the
[

adjustments into a dummy load or antenna system
presenting impedance very close to 0 2hms.
In the SSB mode, you may set the desired power
output via 0enu item “
177 TX MAX POWER
”. The
adjustment range is between Watts and 100 Watts.
You should always use the minimum power necessary
to maintain reliable communications.
When performing “on air” tests such as the setup of
microphone gain), be sure to check the freTuency be-
fore transmitting, to avoid interference to others who
may already be using the freTuency.
