Before You Begin. . .
1. Connecting AC Power
There are two power switches on this transceiver, one each on the rear and front panels. If the rear panel’s Power switch is
not turned on, the front panel Power switch will not function.
Ì Push the rear panel’s Power
switch to the I position
to apply power from the
power supply to the OCXO
(Reference Crystal Oven)
and to enable the front panel
power switch.
Ì Press and hold in the front
panel Power switch for two
seconds to turn the transceiver on.
Note
The opening screen will appear on the TFT display, and
the self-check function of the CPU inside the radio will
begin. Then, the µ-Tuning circuitry will receive the data
from the CPU, and it will perform its own self-check, and
will preset itself to the proper settings for the current operating frequency.
While the µ-Tuning circuitry is obtaining the data, the drive
mechanism will move from one end of its range to the
other end (fast), and this will cause a temporary “motor”
noise that can be heard; this, does not represent any trouble
or problem.
When the radio is turned on for the first time, it takes about
50 seconds (from turning the radio on to completing the
self-check) until the radio becomes ready to use; however, from the next time you turn it on, it will take around
10 seconds until the transceiver is ready for full operation.
2. Setting Your Local Time
When first turning on the FT DX 9000, be sure to set the local time to match your location's time zone. If you do not do this,
several functions will not work correctly, including the World Clock, Great Circle Map, etc.; please see the appropriate
section of the TFT Operating Manual for details on Local Time Setup.
3. Configuring Your FT DX 9000 Using the Menu
The FT DX 9000 is configured, at the factory, with its various functions set up in a manner typical for most operation. Via
the “Menu” system, you may change these settings to match the way you want your transceiver to operate.
Menu programming is enabled by pressing the MNU
(Menu) key momentarily. You may then rotate the Main
Tuning Dial to display the desired Menu item, in the menu
list, on the TFT. Each of the settings can be changed or
customized via the CLAR/VFO-B knob, as you like, in
this mode.
Once you have made a change to the configuration of a
Menu item or items, you must press and hold in the
MNU (Menu) key for two seconds to save the new set-
tings and exit to normal operation.
If you wish to cancel a change to a Menu item or items,
just press the MNU key momentarily. If you do not press
and hold in the MNU key in for two seconds, any changes
you have made will not be saved.

4. Connecting and Selecting the Microphone
The FT DX 9000D comes equipped with two microphone connectors: the front panel includes a “Cannon” (XLR) three-pin
connector, while the rear panel provides an eight-pin (round) connector.
As shipped from the factory, the front panel XLR connector is engaged for operation, and the rear panel 8-pin microphone
jack is not connected. If you wish to enable the 8-pin connector instead of the XLR connector, use the Menu to accomplish
this. Note that you may leave microphones connected to both jacks, and may select the microphone you want for operation
on a particular operating mode (SSB, AM, FM, etc.), as well!

5. Extending the Front Feet
In order to elevate the front panel for easy viewing, the front left and right feet of the bottom case may be extended.
Ì Pull the front legs outward from the bottom panel.
Ì Rotate the legs counter-clockwise to lock them in the
extended position. Be sure the legs have locked securely in place, because the transceiver is quite heavy
and an unlocked leg could result in damage, should
the transceiver move suddenly.
Retracting the Front Feet
Ì Rotate the legs clockwise, and push them inward while
rotating to the right.
Ì The front feel should now be locked in the retracted
position.

7. Restarting Power after a Voltage Fluctuation
If your AC mains power should suffer a significant fluctuation or interruption, we recommend that you go through a complete power-up cycle, in order to ensure that all circuits are
properly initialized. To do this, be sure the front panel Power switch is turned off, then set
the rear-panel Power switch to the “O” position. Now unplug the AC cable from the rear
panel of the transceiver, and wait ten seconds. Plug the AC cable back in, set the rear-panel
Power switch to “O,” and now press and hold in the front-panel Power switch for two seconds to turn the transceiver on. After about 50 seconds, all circuits will be initialized, and
normal operation may resume.

FEATURES
Superior Visibility and Logical, Fatigue-reducing Panel Layout
The front panel layout is logically crafted, with the large-aperture main frequency display squarely in the middle of the front panel; the
two large S-meters to the left providing instant recognition of signal strength.
Just as in an aircraft cockpit, the panel meters and the TFT are canted slightly toward the center for maximum visibility.
Large, Multi-colored VFD Fluorescent Display
A proprietary, high-brightness VFD (fluorescent) display is incorporated in the FT DX 9000D, providing outstanding visibility (superior even to the TFT) and easy reading of the important frequency information, whether in dim or bright lighting environments.
Function-Indicating LEDs
The many function status indications on the front panel are clearly identified by the operator, thanks to the innovative multi-color LEDs
incorporated in design. A Red LED indicates that a function is engaged on the Main Band, while an Orange LED shows that the function
is engaged on the Sub Band.
Indirect Illumination
For ease of nighttime operation, the controls on the front panel are indirectly illuminated, thanks to carefully-positioned lamps in the
frame underneath the meters and TFT (depending on model).
Aluminum-Die-Cast Oversized Main Tuning Dial
The Main Tuning Dial is a large-diameter (3.2”/81 mm) dial directly coupled to the magnetic rotary encoder which drives the HRDDS
via microprocessor control. Its heavy weight (7 oz./200 g) and quality mounting and construction provide a smooth “flywheel” effect
during operation, ideal for quick cruising up and down a band.
Oversized Knobs for Most Important Functions
The concentric AF/RF Gain, SHIFT/WIDTH, and CLAR/VFO-B knobs are conveniently located right below the TFT, for ease of access
to these important controls.
World’s First 400 MHz HRDDS Local Oscillator
So as to optimize spurious-free dynamic range in a multi-signal environment, Yaesu’s engineers have introduced the world’s first
HRDDS (High Resolution Direct Digital Synthesizer) as the first local oscillator of the FT
frequency, this local oscillator design ensures extraordinarily low noise, resulting in improved weak-signal reception even on a crowded
band during a weekend contest.
DX 9000D. Dividing directly from this high
New-design Large-area OCXO Reference Oscillator
Serving as the master reference oscillator for the transceiver, the 10 MHz OCXO (Oven Controlled Crystal Oscillator) is a large-area (50
x 50 mm/2” x 2”) oven-stabilized oscillator operating at high temperature, for industry-leading frequency stability rated at 0.03 ppm
over the temperature range –10° to +60° C (–14° to +140° F).
Triple-conversion Design with Optimized Gain Distribution
Taking into account the most efficient transceiver design concept consistent with high performance we have adopted a triple-conversion IF
structure, utilizing a first IF at 40 MHz, a second IF at 455 kHz, and the third IF at 30 kHz (for FM, the 3rd IF is at 24 kHz). Gain distribution
through all stages is carefully optimized, for preservation of high system dynamic range.
Ultra-strong Receiver Front End
YAESU’s outstanding RF-stage filtering establishes a clean performance that allows the rest of the receiver to perform at a high level. By
reducing the ingress of energy from very strong sources like Shortwave Broadcast, local AM/FM/TV stations, and other signal sources,
the overall purity of the spectrum delivered to the RF Amplifier first mixer, and subsequent stages is maintained, and the system
Blocking Dynamic Range is also enhanced.
Large, Multi-function Color TFT Display
The 800 x 480 dot, 6.5” TFT display is loaded with information that enhances operation of your FT DX 9000D. Besides general status
information, the TFT includes an Audio Scope (both audio spectrum and “Waterfall” displays) and Oscilloscope page, an RF Spectrum
Scope, a Log Book, Swept-Frequency SWR along with PA Temperature, Bias Level, and Voltage, Memory Channel List, World Clock
with Grey Line display, and a Great Circle Map centered on your location, plus direction indication and control of Yaesu Rotators!
Compact Flash (CF) Card for Data Management
A Compact Flash card is supplied with every FT DX 9000D, for preservation of transceiver configuration settings along with Log Book
archival data.
Professional-Grade Cannon (XLR) Microphone Connector
The FT DX 9 000D incorporates, for the first time ever in an Amateur Radio transceiver, a balanced-input “Cannon” (XLR) microphone connector on
the front panel, for use with studio-grade professional microphones. A round 8-pin microphone jack is also provided on the rear panel.
Two High-precision Analog Meters (Page 29)
The FT DX 9000D incorporates two large (3.4”/86 mm) high-precision analog meters, for the utmost accuracy in measuring transceiver
performance. Visibility is enhanced by the oversized meter scales, making the meters easy to read at all times.

FEATURES
Separated Clarifier Display (Page 46, 95)
A clearly-separated display window within the main frequency display area contains receiver and/or transmitter frequency offset ("Clarifier") data, for quick comprehension by the operator.
YAESU Custom-designed 32-Bit Floating Point IF DSP (Page 60)
The new IF DSP system, utilizing a TI TMS320C6711 device, is a high-speed 32-bit floating point circuit designed with a unique
objective: to do away with the “digital” sound of many DSP filtering systems, and emulate the “Analog Sound” so familiar and comfortable to HF DX and Contest operators. The result is a leading-edge receiver that has the “feel” of a traditional analog receiver, but with
the flexibility and superb filtering capability of a modern digital filtering system.
New Mu (µ) Narrow-bandwidth High-Q RF Filters Using Large-Diameter (28 mm) Coils (Page 64)
On the 14 MHz and lower Amateur bands, Yaesu’s breakthrough “µ-Tuning” RF preselector filters provide the greatest level of RF
protection ever incorporated into an Amateur Radio transceiver. Utilizing a 1.1” (28 mm) ferrite core stack, driven through a coil
structure, µ-Tuning provides greatly improved RF selectivity, even compared to our VRF (Variable RF Filter) preselector, resulting in an
ultra-strong front end. Insertion of the µ-Tuning filter improves the 3rd-Order Intercept Point by at least 4 dB, and you can operate on
a very crowded band with the utmost confidence in your receiver.
VRF (Variable RF Filter) Preselector Filter (Page 66)
On the 18 MHz and higher Amateur bands, and on 1.8 - 50 MHz on the Sub (VFO-B) band, Yaesu’s robust VRF (Variable RF Filter)
preselector provides a relay-selected RF selectivity much tighter than that afforded by traditional bandpass filter networks. Sealed relays
select heavy-duty inductors and capacitors, providing a tracking RF filter that protects the RF amplifier and following stages from strong
out-of-band energy.
First IF 3 kHz Roofing Filter (Page 25, 67)
In the 40 MHz 1st IF, three selectable roofing filters are provided, in bandwidths of 3 kHz, 6 kHz, and 15 kHz, to protect the following
stages from strong signals that could degrade dynamic range in the first IF amplifier and subsequent stages. The roofing filters are
automatically assigned according to the operating mode, but the operator may override the automatic selections on the fly.
CONTOUR Filter Enhances “Analog Feeling” of DSP Filters (Page 25, 68)
The DSP-based Contour system is a unique five-band filter that may be used to roll off or peak the IF response. It is chiefly useful for
modifying the response of the ultra-sharp DSP filters, allowing you to roll off (or emphasize) certain frequency components. Oftentimes,
the result is that a difficult-to-understand signal suddenly will pop out of the background noise as solid copy.
SLOPED AGC Circuitry (Page 76)
In traditional AGC systems, all signals rising above a certain RF level are then clamped together at the same audio output, so as to
prevent distortion throughout the IF and AF stages. In the FT
provide an AGC response whereby ever-increasing signal strength results in a slightly-louder audio response, still without accompanying distortion. This lets you use your brain to sort out weak signals from strong ones more effectively.
DX 9000D, however, you can engage the “Sloped” AGC capability to

Occasionally a noise burst or a sudden transmission from a loud station may startle you if you have the AF Gain turned up, and may even
damage your hearing temporarily. The FT

“Adjacent Channel Encroachment” S-Meter Monitor (Page 33, 78)
When operating CW in a narrow bandwidth like 300 Hz, you may not be aware of the presence of strong stations that may be making it
difficult for others to hear you. In these situations, the “ACM” (Adjacent Channel Monitor) will take over the Sub Receiver, center it on
the Main Receiver frequency, and display
audio through). This alerts you to the situation, and you can QSY or ask the other station to QSY.

Rugged, High-Output Final Amplifier Design (Page 91)
The final amplifier stage of the FT DX 9000D utilizes push-pull SD2931 MOS FET devices in a conservative, high-stability design. The
large-area die-cast aluminum heat sink is monitored thermostatically, and a quiet cooling fan will engage when the heat sink temperature
rises during long periods of high-power transmission.
Ultra-linear Class-A Operation Capability (Page 90)
The FT DX 9000D’s Class-A capability provides ultra-linear amplifier operation at 75 Watts of power output. Typically, 3rd-order IMD
products are suppressed more than 50 dB, while 5th- and higher-order distortion products are at least 70 dB down during Class-A
operation.
Parametric Microphone Equalizer Circuit (Page 88)
For unmatched flexibility in tailoring your microphone’s audio to match your voice, Yaesu’s engineers have incorporated the industry’s
first Three-Band Parametric Microphone Equalizer, which allows you to enhance or suppress frequency components in three different
audio bands. Equalization may be applied independently to microphones attached to the front and rear panel microphone jacks.

ANTENNA CONSIDERATIONS
The FT DX 9000D is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired
operating frequency. While minor excursions from the 50-Ohm specification are of no consequence, the transceiver’s
Automatic Antenna Tuner may not be able to reduce the impedance mismatch to an acceptable value if the Standing Wave
Ratio (SWR) present at the Antenna jack is greater than 3:1.
Every effort should, therefore, be made to ensure that the impedance of the antenna system utilized with the FT DX 9000D
be as close as possible to the specified 50-Ohm value.
Any antenna to be used with the FT DX 9000D must, ultimately, be fed with 50 Ohm coaxial cable. Therefore, when using
a “balanced” antenna such as a dipole, remember that a balun or other matching/balancing device must be used so as to
ensure proper antenna performance.
The same precautions apply to any additional (receive-only) antennas connected to the RX ANT jack; if your receive-only
antennas do not have an impedance near 50 Ohms at the operating frequency, you may need to install an external antenna
tuner to obtain optimum performance.
ABOUT COAXIAL CABLE
Use high-quality 50-Ohm coaxial cable for the lead-in to your FT DX 9000D transceiver. All efforts at providing an efficient
antenna system will be wasted if poor quality, lossy coaxial cable is used. This transceiver utilizes standard “M” (“PL-259”)
type connectors, except for the “RX OUT” BNC connectors used for special filters, etc.

INSTALLATION AND INTERCONNECTIONS
GROUNDING
The FT DX 9000D HF transceiver, like any other HF communications apparatus, requires an effective ground system for
maximum electrical safety and best communications effectiveness. A good ground system can contribute to station efficiency in a number of ways:
Ì It can minimize the possibility of electrical shock to the operator.
Ì It can minimize RF currents flowing on the shield of the coaxial cable and the chassis of the transceiver; such currents
may lead to radiation which can cause interference to home entertainment devices or laboratory test equipment.
Ì It can minimize the possibility of erratic transceiver/accessory operation caused by RF feedback and/or improper cur-
rent flow through logic devices.
An effective earth ground system make take several forms; for a more complete discussion, see an appropriate RF engineering 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” configuration, and bonded together at the apex of the “V” which is nearest
the station location. Use a heavy, braided cable (such as the discarded shield from type RG-213 coaxial cable) and strong
cable clamps to secure the braided cable(s) 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 25 mm (1”) diameter should be used. An
alternative 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 devices such as transceivers, power supplies, and
data communications devices (TNCs, etc.) should be made directly to the ground bus using a heavy, braided cable.
Do not make ground connections from one electrical device to another, and thence to the ground bus. This so-called “DaisyChain” grounding technique may nullify any attempt at effective radio frequency grounding. See the drawing below for
examples of proper grounding techniques.
Inspect the ground system - inside the station as well as outside - on a regular basis so as to ensure maximum 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 significant explosion hazard, and must never be used.

KEY, KEYER, AND COMPUTER-DRIVEN KEYING INTERCONNECTIONS
The FT DX 9000D includes a host of features for the CW operator, the functions of which will be detailed in the “Operation”
section later. Besides the built-in Electronic Keyer, two key jacks are provided, one each on the front and rear panels, for
convenient connection to keying devices.
The Menu system allows you to configure the front and rear panel KEY jacks according to the device you wish to connect.
For example, you may connect your keyer paddle to the front panel KEY jack, and use Menu #041 for paddle input, while
connecting the rear panel’s KEY jack to the keying line from your personal computer (which emulates a “straight key” for
connection purposes), and configure the rear panel jack using Menu #43.
Both KEY jacks on the FT DX 9000D utilize “Positive” keying voltage. Key-up voltage is approximately +5V DC, and keydown current is approximately 1 mA.

FRONT PANEL CONTROLS
MOX Switch
Pressing this button engages the PTT (Push to Talk)
circuit, to activate the transmitter. It must be in the
undepressed position for reception. This switch replicates the action of the Push to Talk (PTT) switch on
the microphone. When engaging the MOX switch,
or otherwise causing a transmission to be started, be
certain you have either an antenna or 50-Ohm dummy
load connected to the selected Antenna jack.
VOX Switch
VOX Operation: This button enables automatic voiceactuated transmitter switching in the SSB, AM, and
FM modes. While activated, the LED inside this button glows red. The controls affecting VOX operation
are the front panel’s VOX and DELAY knobs
(see section ( ) below. By proper adjustment of these
controls, hands-free voice-actuated operation is possible.
DIM Switch
Press this button to lower the illumination intensity of
the analog meters, the frequency display, and the TFT.
Press it once more to restore full brightness.
Advice
Menu Items “DISPLAY 014 DIMMER-METER” and
“DISPLAY 015 DIMMER-VFD” allow you to configure the dimming levels for the analog meters and
the frequency display/TFT independently, so you can
customize the brightness levels.
PHONES Jack
A 1/4-inch, 3-contact jack accepts either monaural or
stereo headphones with 2- or 3-contact plugs. When a
plug is inserted, the loudspeaker is disabled. With stereo headphones such as the optional YH-77STA, you
can monitor both Main (VFO-A) and Sub (VFO-B)
receiver channels at the same time during Dual Receive operation.
Note: When wearing headphones, we recommend that
you turn the AF Gain levels down to their lowest settings before turning power on, to minimize the impact
on your hearing caused by audio “pops” during switchon.
POWER Switch
Press and hold in this switch for two seconds to turn
the transceiver on, after first setting the rear panel
Power switch to the “I” position. Press and hold in
this switch for two seconds, similarly, to turn the transceiver off. If the rear panel’s Power switch is set to the
“O” position, the front panel POWER switch will
not function.
Advice
This is the actual power On/Off switch for turning on
the transceiver. When the rear panel’s Power switch is
set to the “I” position, power is supplied to the OCXO
to stabilize the reference oscillator, and the remainder
of the transceiver is set in a “stand-by” mode, awaiting the command for the transceiver to switch on via
the front panel POWER switch. For further information on the rear panel Power switch, please see the
discussion on page 36.

KEY Jack
This 1/4-inch, 3-contact jack accepts a CW key or
keyer paddles (for the built-in electronic keyer), or
output from an external electronic keyer. Pinout is
shown on page 16. Key up voltage is 5 V, and key
down current is 1 mA. This jack may be configured
for keyer, “Bug,” “straight key,” or computer keying
interface operation via Menu Selection “MODE-CW
041 F-KEYER TYPE (see page 135).” There is another jack with the same name on the rear panel, and
it may be configured independently for Internal Keyer
or pseudo-straight-key operation.
Note
You cannot use a 2-contact plug in this jack (to do so
produces a constant “key down” condition).
Cannon (“XLR”) Microphone Connector
This Cannon-type (XLR) connector accepts input from
the Microphone or other XLR-equipped microphone
system. MIC connector pinout is shown on page 15.
Proper microphone input impedance is 500 ~ 600
Ohms.
If you are using a condenser microphone requiring 48
Volts DC, you may enable this voltage to appear on
the microphone line; see page 81. When the 48-volt
supply line has been enabled, the LED adjacent to the
MIC jack will glow red.
To disconnect the microphone plug, draw out the microphone plug while pressing and holding in the silver push-button.
IPO
(Intercept Point Optimization)
The IPO(A) Lamp-button may be used to set the
optimum receiver front end characteristics of the main
receiver circuit for a very strong-signal environment.
Selecting IPO bypasses the front end RF amplifier and
feeds the received signals directly to the first mixer of
the main band (VFO-A) receiver circuit. While the
IPO feature is activated, this button will remain illuminated.
The IPO(B) Lamp-button, similarly, allows direct
feed of the received signals to the first mixer of the
sub band (VFO-B) receiver circuit. While the IPO
feature is activated on the sub receiver, this button
will be lit.
Advice
The FT DX 9000D’s first mixer is an active type, using
four SST310 Junction FETs. This mixer design provides gain to the receiver chain, so the noise figure of
the receiver is fundamentally lower than with some
other designs. Therefore, it frequently is not necessary to utilize the RF preamplifier, and the receiver
Intercept Point will be substantially increased by engaging IPO, so as to feed the incoming signals directly
to the first (active) mixer. We recommend that IPO be
switched on whenever possible.
Switch
ANTENNA SELECT Switches
These momentary buttons select the antenna jack on
the rear panel, with the selection indicated by the LED
in each button. When an antenna has been selected
for operation on the main band (VFO-A), the LED in
the button glows red. When an antenna has been selected for operation on the sub band (VFO-B), the
LED in the button glows umber.
TUNE Switch
This is the on/off switch for the FT DX 9000D’s Automatic Antenna Tuner.
Pressing this button momentarily places the antenna
tuner in line between the transmitter final amplifier
and the antenna jack (the LED will become illuminated). Reception is not affected.
Pressing and holding in this button for 1/2 second,
while receiving in an amateur band, activates the transmitter for a few seconds while the automatic antenna
tuner rematches the antenna system impedance for
minimum SWR. The resulting setting is automatically
stored in one of the antenna tuner’s 100 memories,
for instant automatic recall later when the receiver is
tuned near the same frequency.
Pressing this button momentarily, while the Tuner is
engaged, will take the Automatic Antenna tuner out of
the transmit line.
Note
When the Automatic Antenna tuner is tuning itself, a
signal is being transmitted. Therefore, be absolutely
certain that an antenna or dummy load is connected to
the selected antenna jack before pressing and holding
in the TUNE button to start antenna tuning.

METER Switch
This control switch determines the function of the
Main Meter during transmission.
COMP: Indicates the RF speech compressor
level (SSB modes only).
PO: Indicates the power output level.
SWR: Indicates the Standing Wave Ratio (For-
ward: Reflected).
IDD: Indicates the final amplifier drain cur-
rent.
MIC LVL: Indicates the relative microphone level.
MONI (Monitor) Switch
This button enables the transmit (RF) monitor in all
modes (except CW, in which the monitor function
is always on, to produce the sidetone). While activated, the LED in this button glows red. Adjustment
of the Monitor level is accomplished using the
MONI knob, located just to the right of the
MONI switch.
Advice
When using headphones, the Monitor is highly useful for making adjustments to the Parametric Equalizer or other voice quality adjustments, because the
voice quality heard in the headphones is such a “natural” reproduction of the transmitted audio quality.
MONI PITCH Knobs
MONI Knob
The inner MONI knob adjusts the audio level of the
transmit RF monitor during transmission (relative to the
AF GAIN control), when activated by the MONI button (above).
PITCH Knob
The outer PITCH knob selects your preferred CW
tone pitch (from 300 ~ 1000 Hz, in 50 Hz increments).
The Tx sidetone, receiver IF passband, and display offset from the BFO (carrier) frequency are all affected
simultaneously. The Pitch control setting also affects
the operation of the CW Tuning Indicator, as the center
frequency of the CW Tuning Indicator will follow the
setting of this control.
AGC ATT Knobs
AGC Knobs
This switch selects the AGC characteristics for the Main
(VFO-A) band receiver.
ATT Knobs
This switch selects the degree of attenuation, if any, to
be applied to the Main (VFO-A) receiver input.
Advice
The Attenuator may be used in conjunction with the IPO
switch (# above) to provide two stages of signal reduction when an extremely strong signal is being received.

MIC PROC Knobs
MIC Knob
The inner

Advice
If you adjust the MIC Gain while speaking in a louderthan-normal voice level and watching the ALC level
on the right-side meter, adjust the MIC Gain so that
the ALC reaches over to the right edge of the ALC
scale. Then, when you speak in a more normal voice
level, you’ll be certain not to be over-driving the mic
amplifier stage.

SSB and modes, when activated by the button with
the same name (see next section).
MIC knob adjusts the microphone input
PROC knob sets the compression (input)
PROC (Processor) Switch
This button enables the RF speech processor for SSB
transmission. Processing level is set by the outer control with the same name (see previous section). While
activated, the LED in this button glows red.
Advice
The Speech Processor is a tool for increasing the average power output through a compression technique.
However, if the PROC level control is advanced too
far, the increase in compression becomes counter-productive, as intelligibility will suffer. We recommend
that you monitor the sound of your signal using the
Monitor (with headphones), and watch the Oscilloscope page on the TFT while transmitting (Monitor
must be on), then advance the PROC level only as far
as required to obtain a useful increase in average power
output.
VOX DELAY Knobs
VOX Knob
The inner VOX knob sets the gain of the VOX circuit, to set the level of microphone audio needed to
activate the transmitter during voice operation while
the VOX button is engaged. The VOX switch
(# above) must be switched On to engage the VOX
circuit.
DELAY Knob
The outer DELAY knob sets the hang time of the
VOX circuit, between the moment you stop speaking,
and the automatic switch from transmit back to receive. Adjust this for smooth VOX operation, so the
receiver is only activated when your transmission is
ended and you wish to receive.
For CW operation, you can adjust the keying delay
separately; see control # below.
KEYER Switch
This button toggles the internal CW keyer on and off.
While activated, the LED in this button glows red. The
Keyer sending speed, and the CW Hang Time are adjusted via the controls described in the next section.
SPEED CW DELAY Knobs
The internal Electronic Keyer is activated by the
KEYER switch, described in the previous section.
SPEED Knob
The inner SPEED knob adjusts the keying speed of
the internal CW keyer. Clockwise rotation increases
the sending speed.
CW DELAY Knob
This outer CW DELAY knob sets the hang time of
the CW “VOX” circuit, between the moment you stop
sending, and the automatic switch from transmit back
to receive during “Semi-break-in” operation. Adjust
this just long enough to prevent the receiver from being restored during word spaces at your preferred sending speed. Clockwise rotation increases the hang time.
Note
The SSB VOX hang time is adjusted via the DELAY control described in section above.
BK-IN/SPOT Switches
This button turns the full break-in (QSK) CW capability on and off. While QSK is activated, the LED in
this button glows red.
The SPOT button turns on the CW receiver spotting tone; by matching the SPOT tone to that of the
incoming CW signal (precisely the same pitch), you
will be “zero beating” your transmitted signal on to
the frequency of the other station.
NB/SQL Knobs
NB Knob
The inner NB knob adjusts the noise blanking level
when the (analog) IF noise blanker is activated by pressing the NB button. The Noise Blanker is activated
via the NB switch, described in the next section.
SQL Knob
The outer SQL knob sets the signal level threshold
at which main (VFO-A) receiver audio is muted, in
all modes. It is very useful during local rag-chews, to
eliminate noise between incoming transmissions. This
control is normally kept fully counter-clockwise (off),
except when scanning and during FM operation.
Page 23FT DX 9000D OPERATION MANUAL
Page 26
FRONT PANEL CONTROLS
NB Switch
Pressing this button activates the (analog) IF Noise
Blanker, which may help reduce many different types
of man-made impulse noise (but not atmospherics).
When the Noise Blanker is activated, the LED inside
the button will glow red. Adjustment of the Noise
Blanker level is accomplished via the NB knob, described in the previous section.
VRF/µ-T Switch
This button turns the main band (VFO-A) receiver’s
VRF filter or µ-TUNE filter on and off. While activated, the LED inside the button will glow red.
VRF/µ-T/NTCH Knobs
VRF/µ-T Knob
The inner VRF/µ-T knob tunes the passband of the
main band (VFO-A) receiver’s RF filter (18 MHz and
higher Amateur bands) or µ-TUNE filter (Narrowbandwidth High-Q RF Filter) (14 MHz and lower
Amateur bands) for maximum receiver sensitivity (and
out-of-band interference rejection). On the 18 MHz
and higher Amateur bands, this knob provides adjustment of the VRF (Variable RF Filter) preselector circuit.
Advice
H It is possible to use the Menu to de-select the µ-
Tune module, and utilize VRF instead, on bands
where a µ-Tune module is installed. However, the
superior selectivity of the µ-Tune circuit is preferred for most applications.
H The µ-Tune circuitry automatically tracks your op-
erating frequency, and adjustment of its center frequency is normally not required. However, if a
very strong signal within several dizen kHz is
causing you problems, you may use the VRF/µT / NTCH knob to skew the tuning to one side
of the other of your current frequency, to roll off
the strength of the interfering station.
H If you wish to reset the tuning of the VRF/µ-T /
NTCH knob to its original (centered) setting,
just press and hold in the VRF/µ-T switch (#
above) for two seconds. The µ-Tune circuit will
not revert to its normal (automatically tuned) position, centered on your current frequency.
H There is a slight increase in receiver path insertion
loss when the µ-Tune circuit is engaged. On the
frequencies where µ-Tune is used, this is seldom a
problem. If the slight signal loss presents a problem, just turn the VRF/µ-T switch (# above)
Off.
H Rotation of the VRF/µ-T / NTCH knob to
adjust the µ-Tune circuit should be performed only
to optimize the signal or reduce interference. The
µ-Tune circuit tuning is surprisingly sharp. If you
are adjusting VRF, however, the tuning is much
more broad, and we believe that VRF adjustment
will seldom be required.
H The relative position of the µ-Tune or VRF pass-
band can be observed on the TFT display.
NTCH Knob
The outer NTCH knob adjusts the center frequency

FRONT PANEL CONTROLS
NTCH Switch
This button turns the main band (VFO-A) IF notch
filter on and off. When the IF notch filter is activated,
the LED inside the button will glow red. The Notch
Filter center frequency is adjusted via the NTCH
knob, described in the previous section.
Advice
H The width of the notch may be set to either “Wide”
or “Narrow” via Menu item “RX DSP 082 IFNOTCH-WIDTH” in the RX DSP Menu Group.
Setting this selection to “Narrow” will provide a
very sharp notch, with minimal disturbance to the
incoming signal wave-form.
H The tuning rate of the Notch Filter being rather
slow, it frequently is useful to use the Audio Scope
of the TFT (either the Audio Spectrum Scope or
the Waterfall display) to adjust the center frequency of the IF Notch Filter. In the Waterfall
display mode, the notched area will appear more
white than the background screen, while on the
Audio Spectrum Scope screen the notched area
will appear as a “hole” in the noise.
DNF Switch
This button turns the main band (VFO-A) Digital
Notch Filter on and off. When the Digital Notch Filter is activated, the LED indicator will glow red. This
is an automatic circuit, and there is no adjustment knob
for the DNF.
R.FLT Switch
This button selects the bandwidth for the main band
(VFO-A) receiver's first IF Roofing Filter. Available
selections are 3 kHz, 6 kHz, 15 kHz, or Auto, and the
LED indicator will change according to the bandwidth
selected.
Advice
Because the roofing filter is in the first IF, the protection it provides against interference is quite significant. When set to AUTO, the SSB bandwidth is 6 kHz,
while CW is 3 kHz and FM/RTTY are 15 kHz. On a
crowded SSB band, however, you may wish to select
the 3 kHz filter, for the maximum possible interference rejection.
CONT DNR Knob
CONT Knob
The inner
(VFO-B) CONTOUR filter response. The CONTOUR
filter is engaged via the
the next section.
DNR Knob
The outer DNR knob selects the optimum Main
Band (VFO-A) Digital Noise Reduction response. The
Noise Reduction circuit is engaged via the DNR
switch, described in section above.
CONT knob selects the desired sub band
CONT switch, described in
CONT Button
This button turns the sub band (VFO-B) CONTOUR
filter on and off. When the CONTOUR filter is activated, the LED inside the button will glow umber. Adjustment of the CONTOUR filter’s center frequency
is provided by the CONT knob, described in section above.
Quick Note
There are times, when you’re trying to remove interference with a sharp DSP filter, that the remaining signal has a somewhat unnatural sound. This is caused
by the cutting of some frequency components, leaving other components in excess. The CONTOUR filter allows you (especially) to roll off certain frequency
components inside the remaining passband, but in a
smooth manner that helps restore a natural sound and/
or raise intelligibility.
Advice
H The action of the CONTOUR filter (either null-
ing or peaking of frequency components as you
adjust the center frequency) may be adjusted via
Menu item “RX DSP 079 MAIN-CONTOURWIDTH.” The adjustment range includes settings
of -15 dB (nulling) to +10 dB (peaking).
H The Audio Spectrum Scope (including the Wa-
terfall displays) on the Oscilloscope page of the
TFT can be particularly useful when adjusting the
CONT control (see section above), as you
can observe the position of the null or peak in the
audio passband.
DNR Switch
This button turns the Main band (VFO-A) Digital
Noise Reduction circuit on and off. When the Digital
Noise Reduction is activated, the LED inside the button will glow umber. Adjustment of the Noise Reduction level is provided by the DNR knob, described

Advice
H By convention in the Amateur
bands, LSB is used on the 7
MHz and lower bands (with the
exception of 60 meters), while
USB is utilized on the 14 MHz
and higher bands.
H When changing modes from SSB to CW, you will
observe a frequency shift on the display. This shift
represents the BFO offset between the “zero beat”
frequency and the audible CW pitch (tone) you
can hear (the pitch is programmed by the
PITCH control), even though the actual tone
that you hear is not changing. If you do not want
this frequency shift to appear when changing
modes from (for example) USB to CW, use the
Menu item “MODE-CW 050 CW FREQ DISPLAY,” described on page 136.
H When operating on the FM mode, rotate the
SQL (Squelch) control (# ) clockwise just
to the point where the background noise is just
silenced. This is the point of maximum sensitivity to weak signals. Excessive advancement of the
SQL control will degrade the ability of the receiver to detect weak signals. Adjustment of the
Sub (VFO-B) band Squelch is accomplished using the Sub SQL control (# ); see page 31.

CLAR (CLARIFIER) OPERATION ON MAIN (VFO-A
The CLAR button and CLAR/VFO-B knob are used to offset either the receive, transmit, or both frequencies from
their settings on the main band (VFO-A) frequency (the Clarifier does not affect the sub band (VFO-B), however). The four
small numbers on the Multi Display Window show the current Clarifier offset. The Clarifier controls on the FT DX 9000 are
designed to allow you to preset an offset (up to ± 9.999 kHz) without actually retuning, and then to activate it via the
Clarifier’s RX (FAST RX) and TX (BAND/MHz TX) buttons. This feature is ideal for following a drifting station, or for
setting small frequency offsets sometimes utilized in DX “Split” work.
Here is the technique for utilizing the Clarifier:
1. Press the CLAR switch (# ). The LED imbedded
in the switch will glow Red to signify that rotation of
the CLAR/VFO-B knob (# ) will allow setting of
a frequency offset.
2. Press the FAST/RX switch (# ). On the display,
“CLAR” and “RX” will appear, and the programmed
offset will be applied to the receive frequency.
3. Rotation of the CLAR/VFO-B knob will allow you
to modify your initial offset on the fly. Offsets of up to
± 9.99 kHz may be set using the Clarifier.
To cancel the application of the offset to the receiver frequency temporarily, press the FAST/RX switch. The
“CLAR RX” notation will disappear from the display.

frequencies. To clear out the programmed Clarifier offset
altogether, and reset it to “zero,” press the CLAR switch
(# ). The programmed offset is displayed in the small
multi-channel window of the frequency display.
Note
If the Clarifier seems not to be operating, check to see if
the Orange lamp to the right of the CLAR/VFO-B knob

CLAR/VFO-B knob to go out. Now press the CLAR
switch (# ) to begin Clarifier operation.
The LED Bar Display provides a graphical representation of the Clarifier offset.
On CW, the Bar Display field is used for CW Center Tuning, instead of Clarifier Offset, as the transceiver is configured at the factory. If you wish to change this, so that the Clarifier Offset is also displayed on CW, use the following
procedure:
Without changing the receive frequency, you may
alternatively apply the Clarifier offset to the transmit frequency (typically, for “split” DX pile-ups).

DUAL RECEIVE
The FT DX 9000D is capable of simultaneous reception, using the Main (VFO-A) and Sub (VFO-B) receivers, in what is
called the Dual Receive mode. Especially useful for DX work, here is the operating procedure for Dual Receive operation.
1. While receiving on the Main (VFO-A) band, engage
the Sub (VFO-B) receiver by pressing the SUB RX
key (# ). You will now be receiving on the two frequencies shown on the main frequency display.
2. Adjusting the volume:
To adjust the Main (VFO-A) audio level, rotate the
Main AF GAIN control (# ). To adjust the Sub
(VFO-B) audio level, rotate the Sub AF GAIN control (# ). In both cases, clockwise rotation of the
knob will increase the volume level.
3. Press the B switch (# ) to enable the capability to
change the operating mode for the Sub (VFO-B) band.
4. Having pressed the B key in the previous step, you
may also press the BAND keys surrounding the TFT
to select the operating band on which you want to set
up the Sub (VFO-B) receiver.
5. After you have set up the band and mode for the Sub
(VFO-B) band, you should now select the proper antenna, using the ANTENNA SELECT 1 ~ 4 switches
(# ), or, for receive-only capability, the RX (Antenna) switch (# ).
6. Rotate the MAIN tuning dial (# ) to adjust the
Main (VFO-A) frequency, and rotate the CLAR/
VFO-B tuning dial (# ) to adjust the Sub (VFOB) frequency.
7. To cancel Dual Receive operation, and receive just
on the Main (VFO-A) receiver, press the RX switch
(# ); the Orange LED to the right of the CLAR/
VFO-B knob will go out, and monoband operation
on the Main (VFO-A) receiver will resume.
Note
Please remember that, so long as the B Mode switch
(# ) is illuminated, any mode or band changes will still
be applied to the Sub (VFO-B) band, whether or not Dual
Receive is engaged.
Quick Note

Advice
H When operating in Dual Receive, the manner in which
the audio is fed to the left and right sides of your headphones (Stereo, Monaural, or Mixed) may be configured using Menu item “RX AUDIO 076 HEADPHONE MIX” (see page 139).
H When changing modes from SSB to CW, you will ob-
serve a frequency shift on the display. This shift represents the BFO offset between the “zero beat” frequency and the audible CW pitch (tone) you can hear
(the pitch is programmed by the PITCH control:
# ), even though the actual tone that you hear is not
changing. If you do not want this frequency shift to
appear when changing modes from (for example) USB
to CW, use the Menu item “MODE-CW 050 CW
FREQ DISPLAY,” described on page 136.
H When operating on the FM mode on the Sub (VFO-
B) band, rotate the Sub (VFO-B) SQL (Squelch)
control (# ) clockwise just to the point where the
background noise is just silenced. This is the point of
maximum sensitivity to weak signals. Excessive advancement of the SQL control will degrade the ability of the receiver to detect weak signals. Adjustment
of the Main (VFO-A) band Squelch is accomplished
using the Main SQL control (# ).

DUAL RECEIVE: FULL DUPLEX OPERATION
The FT DX 9000D includes a unique capability among HF
transceivers: the ability to operate in a full duplex environment, where by you can transmit on the Main (VFOA) band while simultaneously tuning around, on a different band, on the Sub (VFO-B) band. This affords the contest operator extra tuning time in search of new contacts
and multipliers while calling CQ on the “run” band. This
yields “SO2R” (Single Operator, Two Radio) operating
capability while using only one transceiver!
To engage Full Duplex crossband operation, set Menu item
“TX GNRL 158 FULL DUP” to “DUP” instead of the
default “SIMP” selection. To return to normal (non-duplex) operation, return Menu to SIMP.
When Full duplex operation is engaged, you may receive
on the Sub (VFO-B) band frequency while transmitting,
during dual receive operation, on a different band on the
Main (VFO-A) band. This allows you to tune for contacts
on 15 meters, for example, while calling CQ on 20 meters
during a slow time in a contest. Press the Sub (VFO-B)
band TX Button/LED (# ) to switch transmit control
to that VFO to call a station, then press the Main (VFO-A)
band TX Button/LED (# ) to return to the “run” band
and continue your “CQ” process.
Note
Full Duplex operation within the same band (e.g. both Main
and Sub VFOs on 20 meters) is not possible.
Important Guidelines for Full Duplex Operation
Remember that, at your station location, the capability
exists for damaging RF voltage to be conducted from your
transmitting antenna into your receiving antenna during
full duplex operation. The exact amplitude will depend on
the operating frequency, proximity and polarization alignment of the antennas, and the transmitting power level (including your linear amplifier, if used).
Accordingly, you should take some time, in assembling
your station, to ensure that proper isolation exists between
your station antenna systems. One way to do this is to connect the “receive” antenna coaxial cable to the “Transmitter” jack of low-power Wattmeter, and connect the “Antenna” jack of the Wattmeter to a 50-Ohm Dummy load.
Now transmit on the “TX” antenna you will be using, and
observe the deflection (if any) on the low-power Wattmeter connected to the “receive” antenna. For safe operation
of the FT DX 9000D, you should observe “10 mW” or less
on the Wattmeter.
This capability within a single transceiver is a unique feature of the FT DX 9000D. It relieves you of the need to run
separate key, PTT, and other control lines to two different
radios from your logging computer.

DUAL RECEIVE: FULL DUPLEX OPERATION
Using Headphones for Dual Receive
To take advantage of dual reception, you will want to connect stereo headphones to the PHONES jack. Like the AF GAIN
control, headphone audio mixing can also be configured as desired from Menu Selection “RX AUDIO 076 HEADPHONE
MIX.” Three audio mixing schemes are selectable as follows:
OFF: Audio from the Main band (VFO-A) receiver is heard only in the left ear, and Sub band (VFO-B) receiver audio
solely in the right ear.
MID: Audio from both Main (VFO-A) and Sub (VFO-B) band receivers can be heard in both ears, but Sub band (VFO-
B) audio is attenuated in the left ear and Main band (VFO-A) audio is attenuated in the right ear.
FULL: Audio from both Main (VFO-A) and Sub (VFO-B) band receivers is combined and heard equally in both ears
“Monaural” mode).
Sideband Diversity Reception
Here you receive a single AM signal through the two receivers, each receiving the opposite sideband. Skywave-propagated
signals often show phase distortion in this mode, but it gives you a view of the entire passband, from which you can then
select the best sideband for listening (or for SWL Dx’ing, you may want to listen to both sidebands at the same time, to get
the best copy). On groundwave signals, where the phase of the sidebands is likely to be the same, there is an interesting
sense of depth to the signal.
To tune in a signal using this mode, you should have stereo headphones connected to the front panel PHONES jack or an
external stereo speaker connected to the rear panel EXT SP jacks.
Ì Set the main band (VFO-A) to either LSB or USB
mode, and tune for zero beat on the desired signal.
Ì Press the AB button (# ) to copy this mode and
frequency into the sub band (VFO-B), then press the
mode button to select the opposite sideband for the
main band (VFO-A).
Ì If using headphones, set the headphone mixing scheme
to the “COMBINE-1” mode via the Menu Selection
76: Head Phone Mix , and activate dual reception.
Ì Adjust the AF GAIN knob(s) to balance the vol-
ume of the two receivers.
If interference is present on one of the channels, you may
have to turn its AF GAIN control to suppress that channel
(or press the green “RX” LED/button to disable the receiver with the sideband experiencing interference). Otherwise, try changing the headphone audio mixing scheme
to “FULL” or “OFF” in the Menu Selection “RX AUDIO
076 HEADPHONE MIX” for different effects (or try settings with similar effects on your external amplifier). Although you don’t get the “stereophonic” effect in the monaural mode, the two signals are still mixed, offering the
potential for much better copy than in regular AM or even
single-sideband ECSS modes.

Bandwidth Diversity Reception
This mode involves receiving the same signal through two different bandpass filters. The frequency and mode of both the
Main band (VFO-A) and Sub band (VFO-B) are the same. The main band (VFO-A) can be set up for a narrow bandpass,
and the Sub band (VFO-B) for a wide bandpass, using the WIDTH knobs, resulting in a spatial perception of the channel.
Although any mode (except FM) can be used, CW offers the widest array of choices, and perhaps the most startling effects
on crowded channels.
Stereo headphones or an external stereo speaker are recommended for this mode. To set up the transceiver for bandwidth
diversity reception:
Ì Select the desired mode on the Main band (VFO-A).
Ì Tune to the signal of interest.
Ì Press the AM button (# ) to copy this mode
and frequency into the Sub band (VFO-B).
Ì If using headphones, set the headphone mixing scheme
to the “MID” mode via the Menu Selection “RX AUDIO 076 HEADPHONE MIX” and activate dual reception.
Ì Adjust the AF GAIN knob(s) (# and ) to bal-
ance the volume of the two receivers.
Ì Now try manipulating the SHIFT and WIDTH
controls (on both main band (VFO-A) (# ) and sub
band (VFO-B) (# ) receivers) to observe the interesting effects of bandwidth diversity.

Polarity Diversity
Similar in concept to the bandwidth diversity capability just described, another interesting capability of the FTDX9000
is the ability to use two different antennas on the same frequency, using dual reception. For example, you might have
a horizontal Yagi on the main band, and a vertical antenna on the sub band, then lock the two frequencies together and
engage dual reception.
Frequently, the fading observed on the HF bands is not so much a change in ionization level, but rather a shift in the
polarization of the signal as it travels to and from the ionosphere. Having an opposite-polarization antenna available
can fill in the signal during deep fades, and you may then transmit on whichever antenna is providing the strongest
signal at the moment (see the discussion below on Split Frequency operation).

BAND ST ACK OPERATION
The FT DX 9000D utilizes a triple band-stack VFO selection technique, that permits you to store up to three favorite
frequencies and modes onto each band's VFO register. For example, you may store one frequency each on 14 MHz CW,
RTTY, and USB, then recall these VFOs by successive, momentary presses of the [14] MHz band key. Each Amateur band
key may similarly have up to three frequency/mode settings applied. Both the Main (VFO-A) and Sub (VFO-B) systems
have their own, independent, band stacks.
A typical setup, for the 14 MHz band, might be arranged
like this:
1. Program 14.0250 MHz, CW Mode,
then press the [14] MHz BAND
key (# );
2. Program 14.080 MHz, RTTY Mode,
then press the [14] MHz BAND

of the frequency (the leftmost digit), we will enter the
required digits of the frequency.
2. Press, in order, the digits of the operating frequency,
using the BAND keys (which have the frequencyentry digit or decimal point on the right side of the
slash bar). In this example, enter
[1.8/1]«[7/4]«[50/.]«[3.5/2]«[10/5]
[28/0]«[28/0]«[28/0]«[28/0]
The decimal point after the “MHz” portion of the frequency must be entered, but no decimal point is required after the “kHz” portion.
3. Press the [ENT] key once more. A short “beep” will
confirm that the frequency entry was successful, and
the new operating frequency will appear on the Main
(VFO-A) frequency display fields.

Enter 7.100.000 MHz into the Sub (VFO-B) band:
1. Press the [V/B] key.
2. Press the [ENT] key to engage the direct frequency

of the frequency (the leftmost digit), we will enter the
required digits of the frequency to be entered into the
Sub (VFO-B) band register.
3. Press, in order, the digits of the operating frequency,
using the BAND keys (which have the frequencyentry digit or decimal point on the right side of the

[18/7]«[50/.]«[1.8/1]«[28/0]
[28/0]«[28/0]«[28/0]«[28/0]
4. Press the [ENT] key once more. A short “beep” will
confirm that the frequency entry was successful, and
the new operating frequency will appear on the Main
(VFO-A) frequency display fields.
Advice
H In the above examples, you will notice that the trail-
ing “zero” digits of the frequency were not entered. It
is not necessary to enter these trailing zeroes; just press
the [ENT] to terminate frequency entry, and they will
be entered automatically.
H If you attempt to enter a frequency outside the operat-
ing range of 30 kHz ~ 60 MHz, the microprocessor
will ignore the attempt, and you will be returned to
your previous operating frequency. If this happens,
please try again, taking care not to repeat the error in
the frequency entry process.
Ë Using the CLAR/VFO-B knob (# ), you may
change the Main (VFO-A) band frequency in 1 MHz
steps. If you first press
and hold in the BAND/
MHz key for two seconds, the 1 MHz steps
will be applied to the
Sub (VFO-B) band instead. The imbedded
LED in the BAND/
MHz key will glow Red in the latter case.
When tuning in 1 MHz steps, clockwise rotation of
the CLAR/VFO-B know will increase the frequency,
while counter-clockwise rotation will decrease the frequency.
Ë Using the UP/DOWN switches of the optional
MD-200A8X Base Station Microphone
The UP/DOWN switches on the
optional MD-200A8X Base Station
Microphone may also be used for
manually scanning upward or
downward in frequency, respectively.
The microphone’s UP/DOWN

Advice
At the factory, the audio signals from both the Main and Sub receivers are combined, and the resulting monaural audio takes
advantage of the combined aperture of the two speakers. For most operation, this configuration results in beautiful audio

RECEIVER OPERATION (FRONT END BLOCK DIAGRAM
)
The FT DX 9000D includes a wide range of special features to suppress the many types of interference that may be encountered on the HF bands. However, real world interference conditions are constantly changing, so optimum setting of the
controls is somewhat of an art, requiring familiarity with the types of interference and the subtle effects of some of the
controls. Therefore, the following information is provided as a general guideline for typical situations, and a starting point
for your own experimentation.
The FT DX 9000D’s interference-fighting circuitry begins in its “RF” stages, and continues throughout the entire receiver
section. The FT DX 9000D allows configuration of the features described below independently on the main band (VFO-A)
and sub band (VFO-B), except for the µ-TUNE (Narrow-bandwidth High-Q RF Filter) feature; the sub band (VFO-B)
receiver does not have provision for a µ-TUNE module or modules.
µ-Tune Filters (See page 64)
The µ-Tune filters provide ultra-sharp RF selectivity on the 1.8 ~ 14
MHz Amateur bands on the Main (VFO-A) receiver. Automatic tuning
of the µ-Tune filters is provided via a precision motor drive.
VRF (See page 66)
On the 18 MHz and higher Amateur bands on the Main (VFO-A) receiver, and on all Amateur bands on the Sub (VFO-B) receiver, Yaesu’s
powerful VRF (Variable RF Filter) preselector circuit provides excellent suppression of out-of-band interference, with a passband much narrower than that provided by traditional fixed bandpass filters.
R. FLT (IF Roofing Filters) (See page 67)
Three automatically-selected Roofing filters, in bandwidths of 15 kHz,
6 kHz, and 3 kHz, are provided in the 40 MHz First IF, right after the
first mixer. These filters provide narrow-band selectivity to protect the
following IF and DSP stages, and the filters’ automatically-selected bandwidths may be manually changed by the operator, if desired, for special
operating circumstances.
CONTOUR Filter (See page 68)
The Contour filter is a unique capability of the FT DX 9000D, providing
either nulling or peaking of tunable segments of the receiver passband,
so as to suppress interference or excessive frequency components on an
incoming signal, or to peak those tunable frequency segments. The
amount of nulling/peaking, and the bandwidth over which it is applied,
are adjustable via the Menu.
IF SHIFT (See page 69)
The passband center frequency response of the IF DSP filtering may be
adjusted using this control.
IF WIDTH (See page 70)
The width of the IF DSP filtering may be carried using this control.
IF NOTCH (See page 71)
The IF Notch filter is a high-Q notch filter that can significantly reduce,
if not eliminate, an interfering carrier. The Q (sharpness) of the filter
may be adjusted using the Menu, and the exact tuning of the filter may
be monitored visually using the Audio Scope page on the TFT (especially useful is the “Waterfall” display).
DNR (Digital Noise Reduction) (See page 72)
The DSP’s Digital Noise Reduction (DNR) feature utilizes sixteen different mathematical algorithms to analyze and suppress different noise
profiles encountered on the HF/50 MHz bands. Choose the selection
that provides the best noise suppression, which concurrently will allow
the signal to rise up out of the noise.
DNF (Digital Notch filter) (See page 74)
When multiple interfering carriers are encountered during reception, the
Digital Notch Filter can significantly reduce the level of these signals.
AGC (See page 75)
The AGC system is highly adaptable to changing signal and fading characteristics, making reception possible under the most difficult conditions.
SLOPED AGC (See page 76)
The Sloped AGC system, instead of clamping a fixed upper bound on
audio output across a wide range of input signals, actually allows the
audio output to rise, very gently, with ever-increasing signal strength.
This capability allows you to separate signals, using your brain, according to signal strength in addition to slight frequency differences.
IF Filter Quality Adjustment (See page 140)
The “Q” (quality factor) of the IF DSP filters may be adjusted independently for the Main (VFO-A) and Sub (VFO-B) receiver IF DSP filters,
using the Menu.
Variable IF Filter Shape Factor (See page 140)
You may adjust the shape factor of the Main (VFO-A) and Sub (VFOB) receiver IF DSP filters, using the Menu.

IPO (INTERCEPT POINT OPTIMIZATION
Normally, the front-end FET RF amplifiers provide maximum sensitivity for weak signals. During typical conditions on
lower frequencies (where strong signals and high noise are common), the RF amplifiers can be bypassed by pressing the
IPO button so that the button's illumination is lit. This improves the IMD (intermodulation distortion) rejection characteristics of the receiver, with only a slight reduction of sensitivity. On frequencies below about 10 MHz, you generally will
want to keep the IPO button engaged at all times, as the preamplifiers are usually not needed at these frequencies unless
you are using a Beverage or other lossy receive antenna.
Quick Note
The FT DX 9000D’s first mixer is an active type, using four SST310 Junction FETs. This mixer design provides gain to the
receiver chain, so the noise figure of the receiver is fundamentally lower than with some other designs. Therefore, it
frequently is not necessary to utilize the RF preamplifier, and the receiver Intercept Point will be substantially increased by
engaging IPO, so as to feed the incoming signals directly to the first (active) mixer. We recommend that IPO be switched on
whenever possible.
Main (VFO-A) IPO Setup
Press the Main (VFO-A) side’s -IPO switch key
(# ) to engage the IPO on the Main (VFO-A) band.
A Red LED imbedded in the switch will light up, and the
preamplifier for the Main (VFO-A) receiver will be bypassed. The system gain and sensitivity will be reduced.
To cancel IPO operation and restore full system gain and
sensitivity, press the -IPO switch key once more.

Advice
If background noise causes the S-meter to deflect on clear frequencies, turn the AT T knob clockwise until the S-meter
drops to about “S-1.” This setting optimizes the trade-offs between sensitivity, noise, and interference immunity. Also, once
you have tuned in a station you want to work, you may want to reduce sensitivity further (or add more attenuation) by
turning the AT T knob to a more clockwise setting. This reduces the strength of all signals (and noise) and can make
reception more comfortable, important especially during long QSOs.
When looking for weak signals on a quiet band, you will want maximum sensitivity, so the IPO should be disabled and the
AT T knob should be set to “0.” This situation is typical during quiet times on frequencies above 21 MHz, and when using
a small or negative-gain receiving antenna on other bands.

RF GAIN (SSB/CW/AM MODES
The RF Gain controls provide manual adjustment of the gain levels for the receiver RF and IF stages, to account for noise
and/or signal strength conditions at the moment.
Main (VFO-A) RF Gain Adjustment
The Main (VFO-A) RF GAIN control (# ) should,
initially, be rotated to the fully clockwise position. This is
the point of maximum sensitivity, and counter-clockwise
rotation will gradually reduce the system gain.
As the RF GAIN control is rotated counterclock-
wise to reduce the gain, the S-meter reading will rise.
This indicates that the AGC voltage being applied to
the receiver (to reduce the gain) is increasing.
Rotating the RF GAIN control to the fully counter-
clockwise position will essentially disable the receiver,
as the gain will be greatly reduced. In this case, as well,
the S-meter will appear to be “pegged” against the right
edge of the analog S-meter scale.
The sub (VFO-B) receiver’s RF GAIN control (# )
operates identically to the Main (VFO-A) band RF
GAIN control. The effects of counter-clockwise rotation of the Sub receiver’s RF GAIN control may
be observed visually on the Sub (VFO-B) band S-meter.

Advice
Reception frequently can be optimized by rotating the RF
Gain control slightly counter-clockwise to the point where
the incoming noise level is just about the same as the “stationary” meter needle position as set by the adjustment of
the RF GAIN control. This setting ensures that excessive gain is not being utilized, without so much gain reduction that incoming signals cannot be heard.
Quick Point
The RF Gain control, along with the IPO and Attenuator
features, all affect the system receiver gain in different
ways. As a first step in dealing with high noise or a crowded,
high-level signal environment, the IPO generally should
be the first feature engaged, if the frequency is low enough
to allow the preamplifier to be bypassed. Thereafter, the
RF Gain and Attenuator features may be employed to provide precise, delicate adjustment of the receiver gain so as
to optimize performance fully.

USING THE µ-TUNE FEATURE
The µ-Tune system is an advanced preselector for the RF front end of the Main (VFO-A) receiver, providing a much narrower
passband than the VRF circuit. The Q of the µ-Tune filter is so tight as to provide significant suppression of signals little more than
10 kHz away from your current operating frequency, and manual adjustment of the µ-Tune filter’s center frequency allows you to
position the shoulder of the filter in such a way as to enhance interference rejection to one side or another of your current frequency.
Because the insertion loss of the µ-Tune is somewhat higher than that of the VRF, we have also provided the capability to disengage
µ-Tune, and engage VRF, should your antenna and noise environment lead to system noise figure concerns when using µ-Tune.
The FT DX 9000D’s Main (VFO-A) band receiver is equipped with µ-Tune modules covering the 1.8 ~ 14 MHz Amateur
bands. On the 18 ~ 50 MHz bands on the Main (VFO-A) receiver, and on all bands on the Sub (VFO-B) side, the VRF
circuit is provided.
µ-Tune Operation on the Main (VFO-A) Receiver
1. Press the VRF/µ-T switch (# ). The imbedded
Red LED will light up.
The µ-Tune circuit will automatically align itself
onto your operating frequency.
Remember that µ-Tune only operates on the Main
(VFO-A) band on the 14 MHz and lower bands.
2. Now rotate the VRF/µ-T knob (# ) to peak the
response (background noise) or reduce interference.
A pictorial representation of the tuning position
of the µ-Tune filter will appear on the bar graph
on the TFT.
The amount of change in the center frequency of
the µ-Tune filter, when rotating the VRF/µ-T
knob by one click, can be configured using Menu
item “GENERAL 035 µTUNE DIAL STEP.”
If you have performed manual adjustment of the
µ-Tune filter’s center frequency, you may press
and hold in the VRF/µ-T key for two seconds
to re-center the filter response on your current operating frequency.
3. Press the VRF/µ-T switch (momentarily) once more
to disengage the µ-Tune filter; the imbedded Red LED
will switch off. In this mode, only the fixed bandpass
filter for the current band will be engaged.

Quick Note
The permeability-tuning concept utilized in the µ-Tune circuit dates back many decades, as it was incorporated in
such classic transceivers as the FT-101 and FT-901 series,
in addition to the FT DX 400 and similar models. The µTune circuit in the FT DX 9000D is the highest development of this circuit concept ever employed in an Amateur
transceiver.

Advice
The µ-Tune filters are the most advanced, selective RF preselector filters ever incorporated into an Amateur Radio
transceiver. The RF selectivity provided by µ-Tune can be of tremendous value in ensuring quiet, intermod-free reception even in the most crowded bands on a contest weekend. The µ-Tune filters provide RF selectivity on the order of a
few dozen kHz at -6 dB, at the expense of a few dB of system gain on bands where noise figure is seldom an issue. You
will notice that the S-meter deflection, when µ-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 as to make it impossible to hear band noise when µ-Tune is engaged
(highly unlikely), just switch it out or revert to the VRF system, which has slightly less insertion loss.
As you tune around on an amateur band with µ-Tune engaged, the microprocessor automatically commands the stepper
motor driving the toroid core stack to center the filter on your current operating frequency. You may, however, use the
VRF/µ-T knob (# ) to skew the filter response to one side or the other from your operating frequency, to deal with
heavy interference on one side. To re-center the µ-Tune filter on your operating frequency, and eliminate any offset,
press and hold in the VRF/µ-T switch (# ) for two seconds.
A pictorial representation of the tuning position of the µ-Tune filter will appear on the bar graph on the TFT.
While µ-Tune is a superior RF preselection circuit, it may be disabled via the Menu; if this is done, the VRF circuit will
engage when the VRF/µ-T switch is pressed. To disable µ-Tune, go to Menu item “GENERAL 035 µTUNE DIAL

µ-Tune and VRF: Comparisons to Fixed Bandpass Filters
µ-Tune
Inspection of the illustrations to the right will demonstrate
the profound advantage of the µ-Tune circuit. In illustration
[A], the gray area represents the passband of a typical fixed
bandpass filter covering the 1.8 ~ 3 MHz range; this is typical of the kind of bandpass filter found in many high-quality
HF receivers today. Note also the hypothetical distribution
of signals across the 160-meter band.
In illustration
gray passband of the fixed BPF. These narrow segments represents the typical bandwidth of the µ-Tune filter, and one
can see that the passband has been reduced from about 750
kHz 9in the case of the fixed BPF) to a few dozen kHz when
µ-Tune is engaged. The vast majority of the incoming signals
are outside the passband of the high-Q µ-Tune filter, and they
will not impinge on any of the RF/IF amplifiers, the mixers,
or the DSP. Very strong out-of-band signals like this can cause
Intermodulation, blocking, and an elevated noise floor for a
receiver.

The vertical lines in the illustration, once again, represent
hypothetical signals throughout this frequency range.
Figure [b] shows the same fixed BPF, with the white area
representing the typical passband of the VRF filter operating
in the same frequency range. Although the selectivity of the
VRF is not as tight as that of the µ-Tune filter, the RF selectivity of the VRF preselector is still magnitudes better than
that of the usual fixed bandpass filter, affording significant
protection against the ingress of high signal voltage from
strong out-of-band signals.
Advice
With µ-Tuning, the center frequency of the filter is continuously adjustable throughout its operating range, and the quality L/C components ensure a tight passband due to the high Q of the circuit. The RF
preselection design task involves not only the selection of quality L/
C components, but the crafting of a tuning mechanism and tuning
concept that preserves system Q (thus assuring a tight bandwidth)
while providing a wide operating frequency range and consistent,
automated tuning. The smooth tuning is achieved by varying the inductance over a wide range; this is accomplished by motor-driving a
large 1.1” (28 mm) ferrite core stack through a 2” high (50 mm) coil
structure. Three µ-Tune modules provide coverage of the 1.8, 80/40,
and 30/20 meter bands on the FT DX 9000D, and the Q of this circuit,
being over 300, yields unmatched RF selectivity for outstanding rejection of undesired signals.

circuit. VRF provides outstanding rejection of out-of-band signals, and if low gain in your antenna system causes insertion
loss to be a critical factor, you may wish to use VRF, instead of µ-Tune, on the bands below 14 MHz.
VRF on the Main (VFO-A) Band Frequency
1. Press the VRF/µ-T switch (# ) momentarily. The
LED inside the switch will become illuminated, and
the VRF system will be engaged, centered on your
current Amateur band.
2. You may rotate the VRF/µ-T knob (# ) to skew
the position of the VRF system relative to your operating frequency. Because the VRF system is relatively
broad, although still much narrower than the fixed
bandpass filter), you may not hear much difference in
the background noise or signal quality when you make
minor adjustments. However, if you have receiving
problems associated by a very strong signal, rotation
of the VRF/µ-T knob may help reduce the strength
of the interfering station, allowing improved reception of the desired signal.
H After moving the passband of the VRF system manually, you
may re-center it on the current Amateur band by pressing and
holding in the VRF/µ-T switch for two seconds.
H To switch VRF off, press the VRF/µ-T switch momentarily
again. The LED imbedded in the switch will go out, and the
VRF circuit will be removed from the incoming received sig-
nal path.

path for the Sub (VFO-B) receiver.
H The settings of the VRF are set and held in memory indepen-
dently for each Amateur band, so any custom settings will be
maintained despite any band changes you perform.
3. Rotation of the VRF knob (# ) allows adjustment
of the center frequency of the VRF circuit.
H If you have made adjustments to the VRF circuit’s center fre-
quency, press and hold in the VRF/µ-T button for two sec-
onds to re-center the VRF on the center of the Amateur band
on which you currently are operating.

again. The LED imbedded in the switch will go out, and the
VRF circuit will be removed from the Sub (VFO-B) receiver’s

Quick Point
The VRF filter, utilizing high-quality coils and capacitors that provide high Q, yields a passband that is approximately 20%
to 30% the width of a traditional, fixed bandpass filter. As a result, significantly more unwanted signal rejection is provided.
Within each Amateur band, 64 adjustment steps are provided (50 MHz: 8 steps), if you wish to skew the response in a
particular direction so as to enhance interference rejection even more.

R.FLT (ROOFING FILTERS
Narrow-band Roofing Filters of 15 kHz, 6 kHz, and 3 kHz bandwidths are provided in the first IF, right after the first mixer.
These filters provide protection for the 2nd mixer, DSP, and other circuitry that follow and can dramatically improve
reception on a very crowded band (during a contest, etc.). Typically, the AUTO selection mode is satisfactory for most
operating situations, but in an extremely crowded phone band you may wish to select, for example, the 3 kHz roofing filter
for SSB operation.

Quick Point
The “AUTO” selection of the Roofing Filter is based
on the operating mode. However, you may override
the automatic selection, if band conditions warrant a
different (usually, a tighter) selection.
The AUTO mode Roofing Filter selections are shown
below:
AM/FM/FM-PKT 15 kHz
LSB/USB/PKT 6 kHz
CW/RTTY 3 kHz
When the Roofing filter mode is set to “AUTO” and
the Noise Blanker is turned On, the Roofing Filter
bandwidth will automatically be set to 15 kHz, as this
setting provides the most effective noise blanking.
However, you still may override the automatic setting, and select a more narrow Roofing Filter. Noise
blanking may be compromised, however, with a tighter
Roofing Filter in the line.
Terminology
A “Roofing Filter,” as its name implies, places a “Roof” over the receiver’s IF system bandwidth. This “Roof” protects the
circuitry downstream from the first mixer from interference, just as a roof on a house protects the contents from rain and
snow.

CONT (CONTOUR) CONTROL OPERATION
The Contour filtering system provides a gentle perturbation of the IF filter passband, so as to suppress or enhance certain
frequency components modestly, so as to enhance the natural-sounding received signal.
Using Contour on the Main (VFO-A) Receiver
1. Press the Main (VFO-A) CONT switch (# ). The
LED imbedded in the switch will glow Red to confirm that the Contour filter is engaged.
2. Rotate the Main (VFO-A) CONT knob (# ) to
achieve the most natural-sounding audio reproduction
on the incoming signal. To cancel Contour tuning, press
the Main (VFO-A) CONT switch once more.
Using Contour on the Sub (VFO-B) Receiver
1. Pressing the Sub (VFO-B) band’s RX switch will
engage Dual Receive operation.
When the imbedded LED grows green, this is your
confirmation that Dual Receive is in operation.
2. Press the Sub (VFO-B) CONT switch (# ). The
LED imbedded in the switch will glow Orange, confirming that the Contour filter is engaged.
3. Rotate the Sub (VFO-B) CONT knob (# ) to
achieve the most natural-sounding audio reproduction
on the incoming signal. To cancel Contour tuning, press
the Sub (VFO-B) CONT switch once more.
Advice
The TFT’s Audio Scope (on the “Oscilloscope” page)
is particularly useful when adjusting the Contour control. Not only can you see the effect of the notch/peak
of the Contour system, but you also can see the position of the notch/peak with respect to frequency components of interest on the incoming signal. You may
then observe (on the Audio Scope) the effect of the
Contour control while listening to the effect on the
signal, and this will help build your intuition on how
best to use Contour tuning in the future.
The Width of the Contour filter effect, and the degree
of nulling or peaking, may be adjusted using the menu.
G The Contour filter’s level (either nulling or peaking) may be
adjusted using Menu Item “RX DSP 078 MAIN-CONTOUR-
LEVEL” for Main (VFO-A) Band and “RX DSP 080 SUB-
CONTOUR-LEVEL” for Sub (VFO-B) Band. The factory de-
fault setting is –15.
G The bandwidth over which the Contour filter effect is applied
may be adjusted using Menu Item “RX DSP 079 MAIN-CON-
TOUR-WIDTH” for Main (VFO-A) Band and “RX DSP 081
SUB-CONTOUR-WIDTH” for Sub (VFO-B) Band. The fac-
tory default setting is 10.

With reference to Figure (B), note the initial position (12 o’clock)

You may observe the “indentation” in the receiver passband where
the Contour filter is placing a low-Q “notch” (per the setting of
Menu #078, referenced above). Counter-clockwise rotation (to
the left) of the Contour knob causes the indentation to move
towered a lower frequency within the passband, while clockwise
rotation (to the right) causes the indentation to move toward a
higher frequency within the passband. By removing interference
or unwanted frequency components on the incoming signal, it is
possible to make the desired signal rise out of the background
noise/interference, enhancing intelligibility.

Quick Point
The steep slopes of the DSP filtering can, when adjusted aggressively, impart an unnatural sound to an incoming signal.
Oftentimes, though, a narrow bandwidth is not the key to improving copy; the incoming signal itself may have undesirable or
excessive frequency components, especially in the low-frequency range around 400 Hz. By judicious use of the Contour
filter, the “shoulder” of the passband response may be altered, or components removed from within the passband, allowing
the desired signal to rise above the background noise and interference in a manner not obtainable with other filtering systems.

IF SHIFT OPERATION (SSB/CW/RTTY/PKT/AM MODES
)
IF Shift allows you to vary the DSP filter passband higher or lower, without changing the pitch of the incoming signal, so as
to reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no need to re-tune the
operating frequency when eliminating the interference. The total passband tuning range for the IF Shift system is ± 1 kHz.

Using IF Shift and Width Together
The IF Shift and Variable IF Width features together form a very effective interference-fighting filtering system.
For example, in Figure (A) you can see how interference has appeared both on the high and low sides of the desired signal. By rotating the WIDTH control, as shown in Figure (B), the interference from one side can be eliminated, and by re-positioning the
SHIFT control (Figure (C)), the interference on the opposite side
can be removed, without re-introducing the interference previously
eliminated in Figure (B).
Advice
For best interference reduction, the Width and Shift features are the
primary tools you should use. After narrowing the bandwidth (Width)
and/or adjusting the center of the passband (Shift), the Contour control may also yield additional signal-enhancement benefits on the
net residual bandwidth. What’s more, the IF Notch Filter (see the
next section) may also be utilized, in conjunction with the three
other filter systems, to significant advantage.

Advice
H The effect of the IF Notch filter may be observed on
the Audio Scope of the TFT (on the “Oscilloscope”
page). The Notch will be observed as a “dip” in the
noise platform observed. What's more, the “Waterfall”
display may be used to observe the effect of the IF
Notch filter, which will appear as a white area in the
colored background area. The tuning rate for the IF
Notch is somewhat slow, allowing precise adjustment,
so the use of the Waterfall display to confirm proper
adjustment is highly recommended.
H The width of the IF Notch null may be adjusted using
Menu Item “RX DSP 082 IF-NOTCH-WIDTH.” Both
“Wide” and “Narrow” selections are available, with
“Narrow” providing the least disruption of the “desired” signal.
H Under the frequency display, you may also use the

in the event of operation on a crowded band where you
wish to receive a weak signal, you may wish to change the
setting (to FAST, for example). The AUTO mode selections are:

USB SLOW
CW FAST

FM FAST
RTTY SLOW
PKT(FM) FAST
PKT(LSB) SLOW
Advice
If the AGC switch is set to the “Off” position, the Smeter will no longer deflect. Additionally, you will likely
encounter distortion on stronger signals, as the IF amplifiers and the following stages are probably being overloaded.
Quick Point
Several aspects of AGC performance may be configured
via the Menu. However, because AGC can have such a
profound impact on overall receiver performance, we generally do not recommend any changes to the AGC Menu
selections.
MAIN (VFO-A)
SUB (VFO-B)
Terminology
Automatic Gain Control, or AGC, is a circuit that senses the incoming signal strength, and then limits the gains of the RF
and IF stages so as to keep the output audio volume at a more-or-less constant level. AGC also protects the RF, IF, Audio,
and DSP stages from overload, as it limits the signal strength that is allowed to flow, irrespective of the input signal level.

SLOPED AGC Operation
In traditional AGC systems, the audio output from the
transceiver becomes essentially fixed once the threshold for AGC action is reached (usually several dozen
dB above the no-signal noise floor). The FT DX 9000D,
however, includes an innovative Sloped AGC system,
that allows the audio volume to rise and fall slightly
according to signal strength. Although the rise/fall are
not dramatic, they are sufficient to allow you to use
your ear to discern and separate signals according to
signal strength, not just audio frequency.
Using Sloped AGC
1. To the bottom right side of the TFT, press the
MNU (Menu) key (# ) momentarily to enter
the Menu mode; the Menu will appear on the TFT.
2. Use the Main Tuning Dial (# ) to select Menu
Item “RX AUDIO 075 AGC-SLOPE.”
3. Rotate the CLAR/VFO-B knob (# ) to change
the setting to “SLOPE.”
4. Press and hold in the MNU key for two seconds
to save the new setting and exit to normal operation. You will now be using the Sloped AGC system.

Main (VFO-A) Band AFL Setup
Press the Main (VFO-A) band’s AFL switch (# ) to
turn on the Audio Limiter. The imbedded LED in the button will glow red. To disable the Audio limiter, press the

ADJACENT CHANNEL MONITOR (ACM) CW MODE ONLY
While operating on CW on the Main (VFO-A) band, the ACM feature provides a visual indicator of encroachment by
another station (someone you may not be able to hear because of the tight DSP filter in your FT DX 9000D). The presence
of a nearby strong signal will be displayed on the Sub-receiver’s S-meter. The Sub (VFO-B) receiver is taken over by the
ACM, when engaged, and reception on the Sub (VFO-B) band is not possible while ACM it turned on.
To activate the Adjacent Channel Monitor, press the
ACM switch (# ). The LED imbedded in the switch
will glow Red.
Advice
H If you do not have Dual Receive engaged, turning on
the ACM feature will cause the RX LED associated with the Sub (VFO-B) receiver to become illuminated.
H When ACM is turned on, the frequency of the Sub
(VFO-B) receiver will automatically be set to match
that of the Main (VFO-A) receiver.
H When operating on Dual Receive, engaging the ACM
feature automatically sets the Sub (VFO-B) receiver
to the same frequency as the Main (VFO-A) receiver,
and by inverting the DSP filter the Sub receiver is used
for monitoring (visually) for activity outside your current receiver passband on the Main receiver.
ACM switch
When ACM is turned on during Dual Receive operation, the audio from the Sub (VFO-B) receiver will disappear.
A typical operating circumstance where ACM can help is when you are running stations during a contest in a 250 Hz
bandwidth. If stations suddenly stop calling you, it may be because another strong station has started calling CQ near
your frequency. By engaging ACM, your Sub-receiver S-meter will display the strongest station on the area ± 1.2
kHz from your current operating frequency; if the encroaching station is sufficiently close, you might want to ask
him or her kindly to QSY.

1. Selecting the Operating Mode
The operating mode is selected
using the
(#
MODE switches
) to the left of the Main
Tuning Dial knob (# ), and the
VFO (A or B) to which the selection is applied is selected by
pressing the A or B switch
above the MODE keys. Press
the A or B key to select the
desired VFO, then press the
LSB or USB key to select one of the SSB modes.
For AM operation, press the AM key.
Quick Point
By convention, LSB is used in the 7 MHz and lower Amateur
bands for SSB communication, and USB is used on the 14 MHz
and higher bands (the 10 MHz band is used for CW and data modes
only).
2. Rotate the Main Tuning Dial knob to adjust the
operating frequency. Alternatively, if using the optional
MD-200A8X Desktop Microphone, you may use the
Up/Down scanning buttons to sweep up or down the
current band.
Advice
Be sure to verify that the microphone you are using is enabled for
operation via the Menu. There are two microphone jacks (the front
panel’s three-pin XLR (“Cannon”) connector, and the rear panel’s
8-pin round connector), and either jack may be chosen indepen-
dently for SSB, AM, and FM operation. See the Menu list below
for details of the associated Menu Item:
3. Press the microphone’s PTT
(Push To Talk) switch to begin transmission; speak into
the microphone in a normal
voice level.
H The “TX” indicator will light
up in the frequency display
area, confirming that transmission is in progress.
H When transmitting in the AM mode, rotate the RF PWR
control (# ) so as to set a maximum (carrier) power output
of 50 Watts.
H Release the PTT switch at the end of your transmission. The
transceiver will return to the receive mode.
4. To adjust the microphone amplifier gain to match the
microphone and your voice level, close the PTT switch,
speak into the microphone in a normal voice level, and
adjust the MIC (gain) control (# ) as follows:
SSB Mode
Adjust the MIC control so that the ALC voltage
(displayed on the right meter) stays within the ALC
zone of the meter (up to 2/3 or full scale deflection)
on voice peaks.
For AM, the MIC control should not be advanced
to the point where the ALC meter deflects. In many
cases, the same setting as used on SSB will be satisfactory.
VOX switchMOX switch
MODE switch
MIC knob
Please adjust the MIC gain control to set the ALC within this range.
Main Tuning Dial
Advice
ALC meter deflection may be caused by excessive
drive power, but also by reflected power detected in
the antenna system. If the impedance presented to the
transceiver is different from 50 Ohms, ALC meter
action may be observed that is not related to the proper
setting of the MIC gain control. Therefore, we recommend that you make MIC gain adjustments into
a dummy load or antenna system presenting an impedance very close to 50 Ohms.
Rotate the RF PWR control to
set the desired power output.
Clockwise rotation of the RF
PWR control will increase the
power. The adjustment range is
between 5 Watts and 200 Watts, and you should always use the minimum power necessary for maintaining reliable communications.
When performing tests (such as the setup of the MIC
or RF PWR controls), be sure to check the frequency
before transmitting, so as to avoid interference to others who may already be using the frequency.
Four techniques for exercising Transmit/Receive con-
trol are provided on the FT DX 9000D, and you may
choose the technique(s) that best suit your operating
needs:
G Pressing the microphone’s PTT switch will engage the trans-
mitter.
G The rear panel PTT jack may be connected to a foot switch or
other manual switching device in order to engage the transmitter.

PHANTOM VOLTAGE FOR CONDENSER MICROPHONES
For powering a studio-quality condenser microphone connected to the front panel’s XLR (“Cannon”) connector, it is
possible to enable a 48-volt DC line connected to that jack. Because the improper enabling of this voltage could cause
damage to other microphone types, the simple process for enabling the voltage has been made somewhat complicated, so as
to prevent the voltage from being enabled by accident.
1. Turn the front and rear panel power switches Off.
2. Unplug the AC cable from the rear panel AC IN
jack.
3. Referring to Figure 1, remove the eight screws from
the sides of the transceiver case.
4. Now remove the six screws shown in Figure 1 from
the bottom case.
5. Referring to Figure 2, locate jack J28 on the AF Unit,
and remove the jumper plug which is connected across
pins 2 and 3 of J28.
6. Connect the just-removed jumper plug so that it now
is connected across pins 1 and 2 of J28 (instead of the
original position across pins 2 and 3).
7. Replace the six screws to affix the bottom case, and
replace the eight screws from the sides of the transceiver (these screws were removed in steps 3 and 4
above).
8. Connect the AC cable to the rear panel’s AC IN jack.
9. Turn the rear panel’s power switch on, then turn the
front panel power switch on.
10. If the above process has been successfully completed,
you will observe that a small red LED just above and
to the right of the XLR connector is now illuminated.
If this LED is not glowing red, please check the status
of the jumper plug once more.
11. If the red LED is glowing properly, the modification
to enable the phantom 48 Volt line is now complete.

Note
When opening/closing the case, take care with your
screwdriver not to short out internal components, or
touch them in a way that will cause them to short
out against other components.
Avoid touching internal components with your hand,
as static electricity can cause damage to certain components if appropriate anti-static bench techniques
are employed.
Only engage the phantom power when you have no
alternative but to use a condenser microphone requiring such voltage. The wide availability of studio-grade Dynamic microphones (that do not require
the phantom voltage) generally makes the use of the
phantom voltage unnecessary over the life of the
transceiver. Because damage can occur if the phantom voltage is enabled on a microphone not requiring it, we strongly recommend that the jumper plug
at J28 (AF Unit) be left in its original position across
pins 2 and 3.
The phantom voltage capability of the FT DX 9000D
is disabled at the factory, and the lack of this voltage
is not a “defect” or other condition covered by the
Limited Warranty on this product. Accordingly, if
you do not feel capable of enabling the phantom
voltage and ask a service shop to do so on your behalf, a service fee may apply.

Phantom Voltage
Phantom Voltage is a term describing the voltage (48 Volts

enabling of the voltage only requires that the position of
an internal jumper plug be moved.

USING THE AUTOMATIC ANTENNA TUNER
The Automatic Antenna Tuner (hereinafter referred to as the “ATU”) built into each FT DX 9000D is crafted to ensure a 50Ohm load for the final amplifier stage of the transmitter. We recommend that the ATU be used whenever you operate on the
FT DX 9000D.
Advice
The ATU of the FT DX 9000D, being located inside the station, only adjusts the impedance presented to the transceiver
at the station end of your coaxial cable feedline. It does not “tune” the SWR at the antenna feedpoint itself. When
designing and building your antenna system, we recommend that every effort be made to ensure a low SWR at the
antenna feedpoint.
The ATU of the FT
Amateur band, so that each band has at least one setting preset for use on that band. The remaining 89 memories are
reserved for the 89 most-recent tuning points, for quick frequency change without the need to retune the ATU.
The ATU in the FT DX 9000D is designed to match impedances within the range of 16.5 Ohms to 150 Ohms, corre-
sponding to an SWR of 3:1 or less. Accordingly, simple non-resonant whip antennas, along with random-length wires
and the “G5RV” antenna (on most bands) may not be within the impedance matching range of the ATU.
DX 9000D includes 100 memories for tuning data. Eleven of these memories are allocated, one per
ATU OPERATION
1. Rotate the RF PWR control (# ) fully clockwise
(to the right).
2. Use the Main Tuning Dial knob (# ) to set the
radio to desired operating frequency within the Amateur band.
3. Press the TUNE switch (# ) momentarily to place
the ATU in the transmit line (no adjustment/tuning will
occur yet). An LED inside the TUNE switch will
glow red continuously.
Quick Point
The momentary press of the TUNE switch will turn
the tuner on, and the microprocessor will automatically select the tuning point closest to the current operating frequency.
4. Press and hold in the TUNE switch for two seconds to begin automatic tuning. The transmitter will
be engaged, and the red LED imbedded in the TUNE
switch will blink while tuning is in progress. When
the optimum tuning point has been reached, the radio
will return to receive, and the red LED will again glow
steadily (instead of blinking).
5. While tuning around the band using the Main tuning
dial, you will observe that the TUNE LED blinks
momentarily every 10 kHz. This momentary blinking
indicates that a new tuning window has been entered.
If you want to save tuning data associated with this 10
kHz window, repeat step 4 (above) for each such window. On bands like 1.8 MHz where the impedance
may change rapidly, the storage of a number of tuning
points is recommended.
6. To disconnect the ATU from the transmit line, press
the TUNE switch momentarily. The red LED imbedded in the TUNE switch will go out, confirming that the ATU has been turned off. In the “Off”
mode, the transceiver will be directly connected to
the coaxial cable connected to your antenna, and will
operate based on whatever impedance is present at
the station end of the coax.
TUNE switch
RF PWR knob
Advice
The ATU is connected both to the transmitter and the receiver, and its natural RF selectivity has a beneficial effect
in rejecting out-of-band energy during reception. Accordingly, we recommend that the ATU be left “On” at all times.
Quick Point
As shipped from the factory, only one ATU alignment
point is saved on each Amateur band. This was memorized during the final alignment and performance verification stages on the production line.
The momentary flickering of the TUNE switch’s
LED occurs whenever you cross over into a new 10
kHz ATU memory window.
Note
Although transmitter power is decreased to 100 Watts
(maximum) during tuning, by all means please check the
operating frequency before beginning the tuning process,
to be sure you are not interfering with others who may
already be using the frequency.
“HI-SWR”

Terminology
Antenna Tuner Memories
The microprocessor of the ATU makes a note of the positions of the tuning capacitors and the selected inductors, and stores
the data for each 10 kHz window in which tuning has occurred. This eliminates the need to re-tune every time you return to
a frequency on which you already have completed the tuning process.

If a high SWR conditions exists (above 3:1), corrective action must be taken in the antenna system to bring the impedance
closer to 50 Ohms. Besides the fact that the ATU will refuse to memorize settings on frequencies where the SWR exceeds
3:1, the high SWR may indicate a mechanical failure in the feed system, and such failures can lead to the generation of
spurious signals causing TVI, etc.

LITHIUM BATTERY REPLACEMENT
The memories for the ATU are backed up by a common Lithium backup battery (type CR2032 or equivalent). After two or
more years of heavy use, you may notice that the tuner memories are not being maintained, and that you have to re-tune
when returning to a frequency on which you had previously stored tuning data.
In this case, please replace the ATU Backup Battery using the following procedure:
1. Turn the transceiver’s main power switch Off.
2. Unplug the AC cable from the rear panel’s (~AC IN)
jack.
3. Referring to Figure 1, remove the eight screws ()
from the side of the transceiver, along with the six
screws () affixing the bottom case; remove the bottom case.
4. Now remove the three screws affixing the top case,
and remove the top case (Figure 2).
5. Referring to Figure 3, remove the screws ( ) at the
top left and top right that hold the front panel assembly in place, and loosen the two screws ( ) at the
bottom left and bottom right, so they can hold the front
panel as it is folded forward.
6. Refer to Figure 4, and slide the front panel diagonally
upward and outward, then fold the front panel forward to expose the Control Unit behind it.
7. Locate the Lithium battery on the left side of the Control Unit (Figure 5)
8. Follow the guidelines in Figure 6, and remove the old
battery, replacing it with a new one of the identical type.
9. Restore the front panel to its original position, and
replace the two screws (one from each side, near the
top) and tighten the two lower screws that were loosened in step 5. Replace the top and bottom covers, reinstalling all the screws removed in steps 3 and 4.
Replace the eight screws removed from the sides of
the transceiver.
10. Replace the top and bottom covers, re-installing all
the screws removed in steps 3 and 4.
11. ATU Backup Battery replacement is now complete.
Figure 1
Quick Point
When the ATU Backup Battery is replaced, all tuner memories will be erased, and new sets of tuning data will have to
be stored.
Note
Use care in the handling and storage of the Lithium
battery. It is small, and presents a choking hazard to
small children; therefore keep such batteries out of
the reach of children at all times. Do not dispose of
Lithium batteries in fire, and do not attempt to recharge them under any circumstances.
When opening/closing the case, take care with your
screwdriver not to short out internal components, or
touch them in a way that will cause them to short out
against other components.
The exhaustion of the ATU backup battery of the FT
DX 9000D is a normal “wear and tear” situation, and
the loss of the backup voltage is not a “defect” or other
condition covered by the Limited Warranty on this
product. Accordingly, if you do not feel capable of
replacing the battery, and ask a service shop to do so
on your behalf, a service fee may apply.

ADJUSTING THE SSB TRANSMITTED BANDWIDTH
For transmission on SSB, a default bandwidth of 2.4 kHz is provided. This bandwidth provides reasonable fidelity along
with good talk power, and is typical of the bandwidth used for decades during SSB transmission. However, the bandwidth
may be varied by the operator, so as to provide different levels of fidelity or talk power, according to your preferences.
Here’s how to adjust the transmitted bandwidth on SSB:
1. Press the MNU switch (# ) to engage the Menu.
2. Rotate the Main Tuning Dial knob (# ) so as to
select Menu Item “MODE SSB 070 SSB-TX-BPF.”
3. Rotate the CLAR/VFO-B knob (# ) to select the
desired bandwidth. The available selections are
3000WB/50-3000/100-2900/200-2800/
300-2700/400-2600,
and the default is 300-2700 Hz.
4. Press and hold in the MNU switch for two seconds
to save the new setting and exit to normal operation.
Advice
You may verify the effect of your adjustments of the
transmitted bandwidth by observing the Audio Scope
on the “Oscilloscope” page of the TFT.
The Transmit Monitor is another helpful way of veri-
fying the effects on fidelity of changing the bandwidth.
Press the MONI switch (# ), then adjusting the
MONI control (# ) for a comfortable listening
level while you are transmitting, you will be able to
hear the difference in sound quality as you make
changes.
Quick Point
The higher fidelity associated with wide bandwidth
will be particularly enjoyable on the low bands, during local rag-chew QSOs.
The “3000WB” setting is a special hi-fidelity setting,
whereby the transmitted bandwidth is in excess of 3
kHz. This selection, in conjunction with judicious
adjustment of the Parametric Microphone Equalizer
(see next chapter) can provide truly outstanding fidelity and very natural-sounding audio.
When using the wider bandwidth selections (especially
“3000WB”), the apparent power output from the transmitter may seem lower. This is because the available
power from the transmitter is being distributed over a
wider bandwidth, and the power detection circuitry
does not compensate for the effect of the bandwidth
selection (it is calibrated in the default 2.4 kHz bandwidth).

IGNAL QUALITY ENHANCEMENT USING THE PARAMETRIC MICROPHONE EQUALIZER
The FT DX 9000D includes a unique Three-Band Parametric Microphone Equalizer, that provides precise, independent
control over the low-, mid-, and treble-ranges in your voice wave-form.
Quick Point
The Parametric Equalizer is a unique technique for adjusting the signal quality. Because the three ranges may be
adjusted so precisely , it is possible to craft a response that provides a more natural and pleasant sound than you have
ever experienced before.
The Parametric Equalizer adjustments are applied independently to the front XLR (“Cannon”) and rear (8-pin) micro-
phone jacks, so you can connect different microphones and customize the audio response that best suits each microphone.
The aspects of configuration that you may adjust on the Parametric Equalizer are:
Center Frequency: The center frequency of each of the three bands may be adjusted.
Gain: The amount of enhancement (or suppression) within each band may be adjusted.
Q: The bandwidth over which the equalization is performed may be adjusted.

LOW- DISTORTION CLASS-A OPERATION
Class-A operation of the FT DX 9000D transmitter is provided, yielding ultra-low distortion products during SSB operation.
Power output during Class-A operation is 75 Watts.
To engage Class-A operation,
press the CLASS-A switch
(# ). The imbedded Red LED
will light up, confirming that
Class-A operation has been selected.
Engaging the “Class-A” mode
actually places the transceiver
in a condition whereby the Bias
level may be adjusted, using the
BIAS control (# ), to set the transceiver for operation
anywhere between Class A and Class AB (which has lower
heat dissipation but higher distortion products). Clockwise
rotation of the BIAS control increases the Bias, and fully
clockwise rotation of the BIAS control will place the
transmitter in fully Class-A operation. Counter-clockwise
rotation of the BIAS control will move the transmitter
toward Class AB operation.
BIAS knob
CLASS-A switch
To exit from the CLASS-A mode, press the CLASS-A
switch once more. The Red LED imbedded in the switch
will go out, confirming that the CLASS-A mode has been
disengaged.
Continuous adjustment of the
Bias Level between Class-A
and Class-AB is possible.
Class-AB and Class-A Operating Principle
Class-AClass-AB
Input
Advice
During Class-A operation, ten Amps of Bias current will be flowing, regardless of the modu-
lation level that leads to actual power output. Therefore, if the ambient temperature in your
operation location is high, the transceiver temperature may rise as well, due to the high bias
level (which must be dissipated as heat). Depending on the temperature, you may wish to
reduce the setting of the BIAS control, so as to reduce the amount of heat being generated.
Because you can monitor the heat sink temperature on the TFT, you can always be aware of a rise in temperature during
Class-A operation. Normally, the temperature is below 80°C; if it rises to near or above this value, however, we
recommend you adjust the BIAS control toward Class AB (more to the left) so as to reduce the heat being dissipated.
An innovative aspect of the “Class-A” mode is that the actual power output is always limited to 75 Watts. So even
though you might adjust the BIAS control in the direction of Class-AB operation, the power output will not rise; this
eliminates the need, for example, to re-tune your linear amplifier, if used.

(LOW- DISTORTION CLASS-A OPERATION)
LOW- DISTORTION CLASS-A OPERATION
Quick Point
Class-A operation provides a significant improvement in transmitter distortion suppression. During Class-A, the 3rd-
order IMD products are typically suppressed 50 dB, while the 5th- and higher-order IMD products (that can cause
“splatter” that interferes with others) will typically be suppressed 70 dB or more.
If you are using a linear amplifier such as the VL-1000, the low distortion produced by the FT DX 9000D’s transmitter
means that these intermodulation distortion products will not exist to be amplified by your linear.
High-Power 200-Watt Final Amplifier Stage
The final amplifier stage of the FT DX 9000D utilizes a pair of ST Micro Electronics Corp. SD2931 MOSFET devices
operating at 50 Volts. The push-pull configuration provides low distortion along with high power output. The 120 mm
thermostatically-controlled cooling fan directs forced air across the heat sink, should the heat sink temperature exceed
the temperature that will trigger the thermostat.

CONVENIENT TRANSMITTER ACCESSORIES
VOX: A
Instead of using the microphone’s PTT switch or the front panel MOX switch to activate the transmitter, the VOX (Voice
Operated TX/RX Control) system provides hands-free, automatic activation of the transmitter, based on voice input into
the microphone. Setup of the VOX system takes only a few seconds.
1. To start, set the DELAY and VOX controls (# )
fully counter-clockwise (to the left).
2. Press the VOX switch (# ) to engage VOX operation.
3. Speak into the microphone in a normal voice level,
and rotate the VOX knob clockwise (to the right)
until the point where your voice input activates the
transmitter.
H Do not advance the setting of the VOX control too much,
because to do so will make the transmitter respond to minor
background noises in your station.
4. Now stop speaking, and note the amount of time it
takes for the receiver to recover. If the hang time is
too long or too short; rotate the DELAY knob, while
speaking briefly into the microphone and then pausing, so as to set the desired hang time. Clockwise rotation of the DELAY control will increase the hang
time.
5. To exit from VOX operation, press the VOX switch
once more. We recommend doing this if you are going to leave your station, to prevent inadvertent activation of the VOX system by a ringing nearby telephone, speaker audio from a TV, etc.

USING THE MONITOR
You may listen to the quality of your transmitted signal using the Monitor feature.
1. Press the MONI switch (# ). The imbedded Red
LED will light up, indicating that the Monitor is turned
on.
2. During transmission, rotate the MONI knob (# )
to adjust the audio level from the Monitor. Clockwise
rotation of this knob will increase the volume level.
3. To switch the Monitor off again, press the MONI
switch once more. The Red LED will go out, confirming that the Monitor is now disengaged.
Advice
If you are using the speaker for monitoring, instead of
headphones, excessive advancement of the MONI
control can cause feedback to occur. Additionally, this
feedback can cause the VOX system to hang up in a
loop, making it impossible to return to receive. Therefore, we recommend the use of headphones, if at all
possible, or the minimum usable setting of the
MONI control, if the speaker must be used.
Because the Monitor feature utilizes a sampling of the
transmitter’s IF signal, it can be very useful for checking the adjustment of the Speech Processor or Parametric Equalizer on SSB, and for checking the general signal quality on AM and FM.

Advice
H Please verify that the lamp to the right of the CLAR/VFO-
B knob is not lit up in Orange. If so, this indicates that this
knob is currently engaged for Sub (VFO-B) band tuning. If
the Orange lamp is lit, press the A/B switch (# ), then
press the CLAR switch, to engage Clarifier operation.
CLAR/VFO-B knob
Quick Point
H The Clarifier is frequently used for receiver offset tuning. How-
ever, for DX pile-ups where the DX station is using a split of
less than 10 kHz, the TX Clarifier function is usually the quick-
est way to set the transmitter to the desired offset frequency.
2. Press the BAND/MHz TX switch (# ), located
above and to the right of the CLAR/VFO-B knob.
The “CLAR” and “TX” notation will appear on the
frequency display.
3. Rotate the CLAR/VFO-B switch to set the desired
transmitter offset. A maximum split of ± 9.99 kHz may
be set.
To disengage the transmit Clarifier temporarily, press the
TX switch once more. The “CLAR TX” indication will
disappear from the frequency display area.
To exit from Clarifier operation, press the CLAR switch
once more. The “CLAR” indication will disappear from
the TFT.
Advice
To listen to the pile-up calling the DX station, so as to
find the station currently being worked, you may press
the RX switch (# : above and to the left of the
CLAR/VFO-B knob). Once you have zeroed in on
the station calling the DX (use the SPOT function on
CW for precise alignment of your frequency), you may
then press the RX switch again to cancel the RX
Clarifier, and return to reception on the DX station's
frequency.
Just as with receiver Clarifier operation, the amount
of offset from the original VFO frequency will appear
in the small display window.
As with receiver Clarifier operation, when you turn
the TX Clarifier off the last-used offset is not lost, and
will be available if you turn the TX Clarifier back on.
To clear the Clarifier offset, press the CLAR switch.
Clarifier Offset Bar Indicator
A visual depiction of the relative offset of the Clarifier may be displayed, using the Bar Indicator.
1. Press the MNU key (# ); the Menu list will
appear on the TFT.
2. Rotate the Main Tuning Dial knob (# ) to select Menu item “DISPLAY 016 BAR DISPLAY
SELECT.”
3. Rotate the CLAR/VFO-B (# ) control to select “CLAR” form the available choices; the factory default is “CW-TUNE.”

SPLIT-FREQUENCY OPERATION
A powerful capability of the FT DX 9000D is its flexibility in Split Frequency operation, using the Main (VFO-A) and Sub
(VFO-B) frequency registers. This makes the FT DX 9000D especially useful for high-level DX-pedition use, as the Split
operation capability is very advanced and easy to use.
1. Set the Main (VFO-A) frequency as desired.
2. Set the Sub (VFO-B) frequency.
3. Now press the SPLIT switch (# ). The “Split”
mode will be engaged, and the front panel switch/LEDs
will look like this:
MAIN(VFO-A)
RX switch (# ) “ON” (LED glows Green)
TX switch (# ) “OFF” (LED Off)
SUB(VFO-B)
RX switch (# ) “OFF” (LED Off)
TX switch (# ) “ON”(LED glows Red)
During Split operation, the Main (VFO-A) register will be
used for reception, while the Sub (VFO-B) register will be
used for transmission. If you press the SPLIT switch
once more, Split operation will be cancelled.
You may also press the TX switch located above and to
the left of the Main tuning Dial to return transmit frequency
control to the Main (VFO-A) side, and thereby cancel Split
operation.
Advice
During normal (non-split) VFO-A operation, you may
simply press the Sub (VFO-B) TX switch (located
above and to the right of the CLAR/VFO-B knob:
# ) to engage Split operation. The TX indicator
will glow Red when you press the switch.
During Split operation, pressing the A
B switch
(# ) will reverse the contents of the Main and Sub
VFOs. Press the A
B switch once more to return
to the original frequency alignment.
During Split operation, if you press the RX switch
above and to the right of the CLAR/VFO-B knob,
you will engage Dual Receive operation, and now can
listen to both sides of the DX pile-up, while transmitting on the Sub (VFO-B) frequency. This is very useful for maintaining the timing of your calls, while also
monitoring both sides of the pile-up.
During Split operation, you may also press the TXW
switch (# ; below and to the left of the Main Tuning
Dial) to listen to the TX frequency temporarily.
It is possible to set different operating modes (for ex-
ample, LSB and USB) on the two VFOs used during
Split operation.
During Split operation, it also is possible to set the
Main and Sub VFOs to different Amateur bands, and
it also is possible to engage Crossband Full Duplex
operation for multiplier hunting while calling CQ on
the “TX” band. See page 98 for a discussion of full
duplex operation.

FULL DUPLEX OPERATION
The FT DX 9000D includes a unique capability among HF
transceivers: the ability to operate in a full duplex environment, where by you can transmit on the Main band
(VFO-A) while simultaneously tuning around, on a different band, on the Sub band (VFO-B). This affords the contest operator extra tuning time in search of new contacts
and multipliers while calling CQ on the “run” band. This
yields “SO2R” (Single Operator, Two Radio) operating
capability while using only one transceiver!
To engage Full Duplex crossband operation, set Menu item
“TX GNRL 158 FULL DUP” to “DUP” instead of the
default “SIMP” selection. To return to normal (non-duplex) operation, return Menu #158 to SIMP.
When Full duplex operation is engaged, you may receive
on the Sub (VFO-B) band frequency while transmitting,
during dual receive operation, on a different band on the
Main band (VFO-A). This allows you to tune for contacts
on 15 meters, for example, while calling CQ on 20 meters
during a slow time in a contest. Press the Sub (VFO-B)
band “TX” Button/LED to switch transmit control to that
VFO to call a station, then press the Main (VFO-A) band
“TX” Button/LED to return to the “run” band and continue your “CQ” process.
This capability within a single transceiver is a unique feature of the FT DX 9000D. It relieves you of the need to run
separate key, PTT, and other control lines to two different
radios from your logging computer.
Note
Full Duplex operation within the same band (e.g. both Main
and Sub VFOs on 20 meters) is not possible.
Important Guidelines for Full Duplex Operation
Remember that, at your station location, the capability
exists for damaging RF voltage to be conducted from your
transmitting antenna into your receiving antenna during
full duplex operation. The exact amplitude will depend on
the operating frequency, proximity and polarization alignment of the antennas, and the transmitting power level (including your linear amplifier, if used).
Accordingly, you should take some time, in assembling
your station, to ensure that proper isolation exists between
your station antenna systems. One way to do this is to connect the “receive” antenna coaxial cable to the “Transmitter” jack of low-power Wattmeter, and connect the “Antenna” jack of the Wattmeter to a 50-Ohm Dummy load.
Now transmit on the “TX” antenna you will be using, and
observe the deflection (if any) on the low-power Wattmeter connected to the “receive” antenna. For safe operation
of the FT DX 9000D, you should observe “10 mW” or less
on the Wattmeter.
Repeat this test for each band and antenna combination
that exists at your station. The low bands like 160 and 80
meters should be checked with particular care, as the physical sizes of antennas used on these bands can present very
high RF voltages to the front end of a receiver. Remember
to rotate directional antennas, and engage all “Upper” and
“Lower” combinations in Yagi stacks, so as to account for
different possibilities of mutual coupling between antennas.
If excessive power is being induced onto the “Receive”
antenna, you will need to investigate and install suitable
bandpass filters and/or stubs in order to reduce the induced
power to a safe level. Suitable information may be found
in radio handbooks, and an excellent treatise is available
in the book “Managing Intersection Interference - Coaxial
Stubs and Filters” by George Cutsogeorge, W2VJN; information may be found at www.qth.com/inrad/book.htm.
