GENERAL DESCRIPTION
Congratulations on your purchase of the FTDX5000 Yaesu
amateur transceiver!
Whether this is your first rig, or Yaesu equipment is already
the backbone of your station, rest assured this transceiver
will provide many hours of operating pleasure for years to
come.
The FTDX5000 is an elite-class HF transceiver and will pro-
vide exceptional transmit and receive performance. The
FTDX5000 is designed for the most competitive operating
situations, whether you operate in contests, DX, or digital-
mode environments.
Built on the foundation of the popular FTDX9000 transceiver,
and carrying on the proud tradition of the FT-1000 series,
the FTDX5000 provides up to 200 Watts of power output on
SSB, CW, and FM (50 Watts AM carrier). Digital Signal Pro-
cessing (DSP) is utilized throughout the design, providing
leading edge performance on both transmit and receive.
Available as an option, the DMU-2000 Data Management
Unit will provide extensive display capabilities via a user-
supplied computer monitor: Band Scope, Audio Scope, X-Y
Oscilloscope, World Clock, Rotator Control, extensive trans-
ceiver status displays, and station logging capability.
The Yaesu-exclusive VRF (Variable RF Front-End Filter)
provides exceptional protection from strong nearby signals,
and serves as a high-performance Preselector, ideal for multi-
operator contest environments. The filter is manually tuned,
allowing the operator to optimize sensitivity or signal rejec-
tion with the turn of a knob. For the ultimate in receiver RF
selectivity, the optional RF µ-Tuning Kits may be connected
via the rear panel, providing extraordinarily sharp selectivity
and receiver protection from close-in interference on a
crowded band.
Superb receiver performance is a direct legacy from the leg-
endary FTDX9000, FT-1000D, and FT-1000MP transceiv-
ers. In the VFO-A receive front end, you may select one of
two RF preamplifiers, or one of two IPO (Intercept Point
Optimization) settings, and/or three levels of RF attenuation
in 6-dB steps. The IPO settings provide direct feed to the
first mixer (VFO-B has one IPO setting), Dual Receives are
built into every FTDX5000. Both VFO-A and VFO-B receiv-
ers utilizes DSP filtering, and incorporate many of the fea-
tures of the FTDX9000, such as Variable Bandwidth, IF Shift,
and Passband Contour tuning. Digital Noise Reduction and
Digital Auto-Notch Filtering are also provided, along with a
manually-tuned IF Notch filter. The Sub receiver, used for
monitoring within the same band as the Main receiver, is
ideal for watching both sides of a pile-up, or keeping an ear
on a DX station that is working stations by call area, etc.
On the transmit side, the Yaesu-exclusive Three-Band Para-
metric Microphone Equalizer allows precise and flexible
adjustment of the wave-form to complement your voice. The
microphone Amplitude, Center Frequency, and Bandwidth
may be adjusted independently for the low-frequency, mid-
range, and high-audio-frequency spectra. The transmitted
bandwidth may be adjusted, as well.
Advanced features include: Direct Keyboard Entry of fre-
quency and Band Change, Speech Processor, IF Monitor for
Voice modes, CW Pitch control, CW Spot switch, Full CW
QSK, adjustable IF Noise Blanker, and all-mode Squelch.
Four TX/ RX antenna ports, plus a receive-only antenna port,
are provided on the rear panel. The front and rear key jacks
may be configured independently, for paddle input, connec-
tion to a straight key, or computer-driven keying interface.
Both Digital Voice Recording and CW Message Memory are
provided.
Three unique windows on the right side of the front panel,
display the VFO-B frequency and graphically show the VFO-
A and VFO-B DSP settings. In Menu Mode operation, these
windows display the menu values, for easy setting.
Set up of frequency, band and mode is especially convenient
on the FTDX5000. Besides direct frequency entry for both
the Main and Sub VFOs, separate keys are provided for band
selection. Each band key accesses three independent VFO
frequency/mode/filter settings per band. You can establish
separate VFO settings for three different parts of each band.
The two (Main and Sub) VFOs allow simultaneous recep-
tion and display of two different frequencies, even in differ-
ent modes and with different IF bandwidths. The Dual Re-
ceiver audio can be combined, or partially mixed in each head-
phone, or monitored separately in each ear.
In addition, 99 memories are provided to store: frequency, IF
filter selection, clarifier offset, and scan-skip status. What’s
more, five quick-recall (“QMB”) memories can instantly store
operational settings at the push of a button.
The built-in automatic antenna tuner includes 100 memories
of its own, to automatically store antenna matching settings
for quick recall later.
Dedicated AFSK and FSK connection jacks on the rear panel
provide simple Interfacing for digital modes. Optimization
of the Passband filters, DSP settings, carrier insertion point,
and display offset are all possible via the Menu program-
ming system.
The Yaesu CAT system provides a direct link to the trans-
ceiver CPU for computer control and customization of tun-
ing, scanning, and other operating functions. The FTDX5000
includes a built-in data level converter for direct connection
to a personal computer serial port. Yaesu products are sup-
ported by most of the leading contest and DX logging pro-
grams. The extensive programming protocol is described in
the CAT System, if you wish to write your own software!
Advanced technology is only part of the FTDX5000 story.

CONNECTING AC POWER
The FTDX5000 is equipped with a universal power sup-
ply supporting 100 V to 264 V AC.
Therefore, the FTDX5000 will operate on a voltage range
from 100V to 264 V without changing a voltage select
switch. Just use the power plug that matches your wall
outlet.
ADJUSTING THE MAIN TUNING DIAL TORQUE
The torque (drag) of the Main Tuning Dial knob may be
adjusted according to your preferences. Simply hold down
the rear skirt of the knob, and while holding it in place
rotate the knob itself to the right to reduce the drag or to
the left to increase the drag.
EXTENDING THE FRONT FEET
BEFORE YOU BEGIN
In order to elevate the front panel for easy viewing, the
front left and right feet of the bottom case may be extended.
Pull the front legs outward from the bottom panel.
Rotate the legs counter-clockwise to lock them in the
extended position. Be sure the legs have locked se-
curely 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
Rotate the legs clockwise, and push them inward while
rotating to the right.
The front feet should now be locked in the retracted
position.

ANTENNA CONSIDERATIONS
The FTDX5000 is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired operat-
ing frequency. While minor excursions from the 50-Ohm specification are of no consequence, if the Standing Wave Ratio
(SWR) present at the Antenna jack is greater than 3:1, the Antenna Tuner may not be able to reduce the impedance mis-
match to an acceptable value.
It is very important, therefore, to ensure that the impedance of the antenna system utilized with the FTDX5000 be as close
as possible to the specified 50-Ohm value.
Note that the “G5RV” type antenna does not provide a 50-Ohm impedance on all HF Amateur bands, and an external wide
range antenna coupler must be used with this antenna type.
Any antenna to be used with the FTDX5000 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 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 FTDX5000 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 connector.

INSTALLATION AND INTERCONNECTIONS
GROUNDING
The FTDX5000 transceiver, like any other HF communications apparatus, requires an effective ground system for maxi-
mum electrical safety and best communications effectiveness. A good ground system can contribute to station efficiency in
a number of ways:
It can minimize the possibility of electrical shock to the operator.
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.
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 may take several forms; for a more complete discussion, see an appropriate RF engineer-
ing 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 “Daisy-
Chain” 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 and outside of the station, on a regular basis 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.

CONNECTION OF ANTENNA AND POWER CABLES
Follow the below illustration and advice regarding the proper connection of antenna coaxial cables, ground cable, and the
AC power cable.
ADVICE:
Do not place the transceiver in a location with direct exposure to sunshine.
Do not place the transceiver in a location exposed to dust and/or high humidity.
Ensure adequate ventilation around the transceiver, to prevent heat build-up and possible reduction of performance due
to high heat.
Do not install the transceiver in a mechanically-unstable location, or where objects may fall onto this product from
above.
To minimize the possibility of interference to home entertainment devices, take all precautionary steps including sepa-
ration of TV/FM antennas from Amateur transmitting antennas to the greatest extent possible. Keep transmitting coaxial
cables separated from cables connected to home entertainment devices.
Ensure that the AC power cord is not subject to undue stress or bending, which could damage the cable or cause it to be
accidentally unplugged from the rear panel AC input jack.
Be absolutely certain to install your transmitting antenna(s) such that they cannot possibly come in contact with TV/FM
radio or other antennas, nor with outside power or telephone lines.
Use a short, thick, braided cable
to connect your station equipment
to the buried ground rod (or alter-
native earth ground system).

KEY, KEYER, AND COMPUTER-DRIVEN KEYING INTERCONNECTIONS
The FTDX5000 includes a host of features for the CW operator. These functions will be detailed in the “Operation” section
later. An Electronic Keyer is built-in, and two key jacks are provided, one on the front and one on the rear panel, 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 item “054 A1A F-TYPE” for
paddle input, while connecting the rear panel 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 item “056 A1A R-TYPE”.
Both KEY jacks on the FTDX5000 utilize “Positive” keying voltage. Key-up voltage is approximately +5V DC, and key-
down current is approximately 1 mA. When connecting a key or other device to the KEY jacks, use only a 3-pin (“stereo”)
1/4” phone plug; a 2-pin plug will place a short between the ring and (grounded) shaft of the plug, resulting in a constant
“key-down” condition in some circumstances.

INSTALLATION AND INTERCONNECTIONS
INTERFACING TO OTHER LINEAR AMPLIFIERS
NOTE
The TX/RX switching in the linear amplifier is con-
trolled by switching components in the transceiver. The
relay circuit of the FTDX5000 used for this switching
is capable of switching AC voltage of 100 Volts at up
to 300 mA, or DC voltages of 60 V at 200 mA or 30 V
at up to 1 Amp. To activate the amplifier switching
relay, set Menu item “172 TGEN ETX-GND” to “EN-
ABLE”.
The specified range for ALC voltage to be used with
the FTDX5000 is 0 to –4 Volts DC.
Amplifier systems utilizing different ALC voltages will
not work correctly with the FTDX5000, and their ALC
lines must not be connected if this is the case.

is turned on, the transceiver audio will be muted
for three seconds.
This is the actual power On/Off switch for turning
the transceiver on. In the MP version, when the rear
panel [MAIN POWER] switch is set to the “I”
(ON) position, power is supplied to the OCXO to
stabilize the reference oscillator. The remainder of
the transceiver is set in a “stand-by” mode. For fur-
ther information on the rear panel [MAIN POWER]
switch, please see the discussion on page 35.
CAT Indicator
This LED indicator will flash red when serial CAT com-
mand signals are being exchanged.
ADVICE:
You may disable the LED CAT command signal flash-
ing function, via Menu item “035 GENE CAT IND.”
See page 124 for details.
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 ste-
reo headphones such as the optional YH-77STA, you
can monitor both VFO-A and VFO-B receiver chan-
nels 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 of any
audio “pops” on your hearing during switch-on.
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 15. 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 interface keying operation
via Menu item “057 A1A F-TYPE” (see page 126).
There is another KEY jack 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).

tion Monitor
[MOX] Switch
Pressing this button engages the PTT (Push to Talk)
circuit, to activate the transmitter. The LED inside the
button will glow red during transmit. It must be turned
off (the red LED will be off) for reception. This button
replicates the action of the Push to Talk (PTT) switch
on the microphone. When engaging the [MOX] button
or otherwise starting a transmission, be certain you have
either an antenna or 50-Ohm dummy load connected
to the selected Antenna jack.
[VOX] Switch
This button enables automatic voice-actuated transmit-
ter switching in the SSB, AM, and FM modes. While
activated, the LED inside the button glows red. Proper
adjustment of the front panel [VOX] and [DELAY]
knobs will make hands-free voice-actuated operation
possible.
[TUNE] Switch
This is the on/off switch for the FTDX5000’s Auto-
matic Antenna Tuner.
Pressing this button briefly, places the antenna tuner in
line between the transmitter final amplifier and the an-
tenna jack (The “ ” icon will appear in the dis-
play). Reception is not affected.
Pressing 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 briefly, while the Tuner is engaged,
will take the Automatic Antenna tuner out of the trans-
mit line.
NOTE:
A signal is being transmitted while the tuner is match-
ing the antenna impedance. Therefore, be certain there
is a dummy load or antenna connected to the selected
antenna jack before initiating the tuning sequence.
[MONI] (Monitor) Switch
This button enables the transmit monitor in all modes.
While activated, the “ ” icon appears in the dis-
play. Use the [MONI] knob to adjust the Monitor level.
ADVICE:
The Monitor is highly useful for making adjustments
to the Parametric Equalizer, or other voice character-
istic adjustments, while listening with headphones. The
voice quality heard in the headphones is a “natural”
reproduction of the transmitted audio.
[PROC] (Processor) Switch
This button enables the Speech Processor for SSB
transmission. While activated, the “ ” icon appears
in the display. Adjustment of the Processor level is ac-
complished using the [PROC] knob.
ADVICE:
The Speech Processor uses a compression technique
to increase the average power output. However, if
the [PROC] knob is advanced too far, the increase
in compression becomes counter-productive, and
intelligibility will suffer. We recommend that you
monitor the sound of your signal using the Monitor
(with headphones).
When the optional DMU-2000 Data Management
Unit is connected, you may use the Audio Scope/
Oscilloscope function to help you adjust the set-
ting of the Speech Processor compression level for
optimum performance with your voice and micro-
phone.

)
Switch
Move this knob up or down to select the optimum front
end characteristics of the receiver circuit. Available
selections are “AMP 1”, “AMP 2”, “IPO 1”, or “IPO
2”.
Normally, IPO is set to “AMP1”. If you want to in-
crease the sensitivity, use “AMP2”. When set to
“IPO1”, the IPO performance of the receivers is im-
proved. When set to “IPO2”, the RF preamplifier is
bypassed, yielding direct feed to the first mixer. As a
result, the IPO is improved more.
ADVICE:
Press this knob in briefly to quickly select the
“AMP1” IPO setting.
“IPO 2” can not be selected for VFO-B.
[R.FLT] Switch
Move this knob up or down to select the bandwidth of
the first IF Roofing Filter. Available selections are “300
Hz”, “600 Hz”, “3 kHz”, “6 kHz”, “15 kHz”, or
“AUTO” (“300 Hz” and “600 Hz” are available only
in VFO-A. The “300 Hz” filter is optional, except in
the MP version). The selected bandwidth appears in
the R.FLT column of the Block Diagram Display.
ADVICE:
Press this knob in briefly to quickly select “AUTO”.
Because the roofing filter is in the first IF, the pro-
tection it provides against interference is quite sig-
nificant. When set to “AUTO”, the SSB bandwidth
is 6 kHz, CW is 3 kHz, and FM/RTTY are 15 kHz.
However, on a crowded SSB band, you may wish
to select the 3 kHz filter, for the maximum possible
interference rejection.

ceived signal when Menu item “109 RGEN IF OUT”
is set to “ENABLED”. This signal does not pass through
the roofing filter.
ANT 1, 2, 3, 4 Jacks
Connect your main antenna(s) here, using a type-M
(PL-259) plug and coaxial feedline for each. These an-
tenna ports are always used for transmission. They are
also used for reception, unless a separate receive an-
tenna is connected to the RX ANT IN jack and used
for the receiver. The internal antenna tuner affects only
the antenna(s) connected here, and only during trans-
mission.
RX ANT IN Jack
The BNC jack provides output of the receiver signal
from the Antenna jacks, which are connected to the
“RX” side of the transceiver T/R switching circuitry.
The type-M jack is for a separate, receive-only antenna.
An antenna connected here can be used when the [RX

corresponding to the Ama-
teur band you wish to oper-
ate on.
ADVICE:
One-touch selection of
each Amateur band be-
tween 1.8 and 50 MHz is provided.
The FTDX5000 utilizes a triple band-stack VFO
selection technique. This permits you to store up to
three favorite frequencies and modes for each band
in the VFO registers. For example, you may store
one frequency for 14 MHz CW, one for RTTY, and
one for USB, then recall each VFO by successive,
momentary presses of the [14] MHz band button.
Each Amateur band button has three frequency/
mode settings associated with it.

7. Press the [(DOWN)]/[(UP)] buttons to tune the
VFO-A frequency in 1 MHz
steps.
ADVICE:
You may change the tuning step to 100 kHz via Menu
item “144 TUN MHz SEL”. See page 133.
8. Move the [ANT 1-4] button up or down to select the
appropriate antenna for the band in use. Alternatively,
you may also press the [RX ANT] button to select the
receive antenna, if one is con-
nected. Up to four TX/RX anten-
nas and one RX-only antenna may
be connected.
ADVICE:
Your antenna selection is “remembered” (in con-
junction with the frequency and mode) in the VFO
register in use, when you choose that particular
antenna.
When VFO-A and VFO-B are switched to the same
antenna jack, VFO-B receiver will be automatically
connected to the RX ANT jack.
When both VFO-A and VFO-B are switched to the
RX ANT, the signal output from the RX OUT jack
is connected to the VFO-A receiver.
9. Press the appropriate [MODE]
button to select the desired op-
erating mode.
ADVICE:
By convention in the Ama-
teur 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.
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]
knob), even though the actual tone that you hear is
not changing. If you do not want this frequency shift
to appear when changing modes, you may change
the BFO offset setting in Menu item “066 A1A FRQ
DISP”, described on page 127.
When operating on the FM mode
in the VFO-A, rotate the (VFO-
A)[SQL] (Squelch) knob clock-
wise just to the point where the
background noise is silenced. This
is the point of maximum sensitivity to weak sig-
nals. Excessive advancement of the
Squelch knob will degrade the abil-
ity of the receiver to detect weak
signals. Adjustment of the VFO-B
Squelch is accomplished using the
(VFO-B)[SQL] knob.
10.
Rotate the Main Tuning Dial knob to tune around the
band, and begin normal operation.
ADVICE:
Clockwise rotation of the Main Tuning Dial knob
increases the operating frequency, one “step” of the
synthesizer at a time; similarly, counter-clockwise
rotation of the Main Tuning Dial knob will decrease
the frequency.
A “normal” and a “fast”
step choice is available on
each operating mode.
Pressing the [FAST] but-
ton engages the “Fast”
tuning selection.

CLAR (CLARIFIER) OPERATION ON VFO-A
The [RX CLAR/FAST], [CLEAR], [TX CLAR/LOCK] buttons, and the [CLAR(VFO-B)] knob are used to offset the
receive, the transmit, or both frequencies from their settings on VFO-A (the Clarifier does not affect VFO-B). The four
small numbers on the LCD display show the current Clarifier offset. The Clarifier controls on the FTDX5000 are designed
to allow you to preset an offset up to ±9.999 kHz without actually retuning, and then activate it usning the Clarifier [RX
CLAR/FAST] and [TX CLAR/LOCK] buttons. This feature is ideal for following a drifting station, or for setting the small
frequency offsets sometimes utilized in DX “Split” operation.
Here is the technique for utilizing the Clarifier:
1. Press the [RX CLAR/FAST] button. The “ ” and
“” icons will appear in the display, and the pro-
grammed offset will be applied to
the receive frequency.
ADVICE:
If the “ ” and “ ” icons do not appear, check
to see if the [A/B] button glows orange. If so, press the
[A/B] button to cause the LED in the [A/B] button to
go out. Now, press the [RX CLAR/FAST] button to
begin clarifier operation.
2. Rotation of the [CLAR(VFO-B)] knob will allow you
to modify the initial offset on the
fly. Offsets of up to ±9.999 kHz
may be set using the Clarifier.
To cancel Clarifier operation, press the [RX CLAR/FAST]
button. The “ ” and “ ” icons will disappear from
the display.
ADVICE:
Turning the clarifier “off” simply cancels the application
of the programmed offset from the receive and/or transmit
frequencies. To clear out the programmed clarifier offset
altogether, and reset it to “zero,” press the [CLEAR] but-
ton.
TX CLAR
Without changing the receive frequency, you may
alternatively apply the Clarifier offset to the trans-
mit frequency (typically, for “split” DX pile-ups).
See page 82 for details.
The Tuning Offset Indicator provides a graphical representation of the Clarifier offset.
In CW mode, the Tuning Offset Indicator is depicts the CW Center Tuning, instead of the Clarifier Offset, this is the
factory default setting. If you wish to change this, so that the Clarifier Offset is also displayed on CW, use the
following procedure:
1. Press the [MENU] button to enter the Menu mode.
2. Rotate the (VFO-A)[SELECT] knob to select
Menu item “012 DISP BAR SEL”.
3. Rotate the (VFO-B)[SELECT] knob to select
“CLAR (Clarifier)” (replacing the default “CW
TUNE (CW TUNING)”
selection).
4. Press and hold in the
[MENU] button for two
seconds to save the new
setting and exit to nor-
mal operation.

OPERATION ON 60-METER (5 MHZ) BAND (U.S. VERSION ONLY)
The recently-released 60-meter band is covered, in the FTDX5000, by five special, fixed memory channels. These channels are
set to USB, and they appear between the “last” PMS channel (“P-9U”) and the first “regular” memory channel (Channel 1).
To operate on the 60-meter (5 MHz) band:
1. Press the [V/M] button once, if neccessary, to enter the
“Memory” mode (the “ ” icon will appear on the
display.
2. Press and hold in the [BAND/MCH] button for two
seconds. The button will glow yellow to signify that
rotation of the [CLAR(VFO-B)] knob will allow se-
lection of the memory channel.
3. Memory channels “US-1” through “US-5” are pre-pro-
grammed, at the factory, with the permitted frequen-
cies in the 5 MHz band, and the USB mode is auto-
matically selected on these channels.
4. To exit from 60-meter operation and return to the VFO
mode, just press the [V/M] button.

QUICK POINT:
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.
ADVICE:
When operating in Dual Receive, the manner in which
the audio is fed to the left and right headphones (Ste-
reo, Monaural, or Mixed) may be configured using
Menu item “108 ROUT HEADPHN” (see page 130).
When changing modes from SSB to CW, you will ob-
serve a frequency shift on the display. This shift repre-
sents the BFO offset between the “zero beat” frequency
and the audible CW pitch (tone) you can hear (the pitch
is programmed by the [PITCH] knob), even though
the actual tone that you hear is not changing. If you do
not want this frequency shift to appear when changing
modes, you may change the BFO offset setting in Menu
item “066 A1A FRQ DISP”, described on page 127.
When operating on the FM mode on the VFO-B re-
ceiver, rotate the (VFO-B)[SQL] knob clockwise just
to the point where the background noise is silenced.
This is the point of maximum sensitivity to weak sig-
nals. Excessive advancement of the (VFO-B)[SQL]
knob will degrade the ability of the receiver to detect
weak signals. Adjustment of the VFO-A squelch is ac-
complished using the (VFO-A)[SQL] knob.
DUAL RECEIVE
The FTDX5000 is capable of simultaneous reception on the same amateur band, using the VFO-A and VFO-B receivers,
in the “Dual Receive” mode. This is especially useful for DX work, here is the operating procedure for Dual Receive
operation.
CONVENIENCE FEATURES
1. While receiving on VFO-A, engage the VFO-B receiver
by pressing the (VFO-B)[RX] button, located to the
upper left of the [CLAR(VFO-B)] knob. You will now
be receiving on the two frequencies shown on the LCD
display (for VFO-A) and SUB DISPLAY-
I
(for VFO-
B).
2. Adjusting the volume:
To adjust the VFO-A audio level, rotate the (VFO-
A)[AF GAIN] knob. To adjust the VFO-B audio level,
rotate the (VFO-B)[AF GAIN] knob. In both cases,
clockwise rotation of the knob will increase the vol-
ume level.
3. Press the [B] button, located to the upper left of the
Main Tuning Dial knob. The [B] button will glow or-
ange, and you may now change the operating mode of
the VFO-B receiver by pressing the appropriate
[MODE] selection button.
4. You may also press the [BAND] buttons to select the
operating band for the VFO-B receiver.
5. To return the mode and band selections to VFO-A, press
the [A] button, located to the left of the [B] button.
The [A] button will glow red, and you may now change
the operating mode and band of the VFO-A receiver.
6. Rotate the Main Tuning Dial knob to adjust the Main
VFO-A frequency, and rotate the [CLAR(VFO-B)]
knob to adjust the VFO-B frequency.
ADVICE:
If the VFO-B frequency does not change, check to see
if the orange LED in the [A/B] button is illuminated. If
not, pressing the [A/B] button will cause the [A/B] but-
ton to glow orange. Now, rotate the [CLAR(VFO-B)]
knob to adjust the VFO-B frequency.
7. To cancel Dual Receive operation, and receive only
on the VFO-A receiver, press the (VFO-B)[RX] but-
ton; the imbedded green LED will go out, and
monoband operation on the VFO-A receiver will re-
sume.
NOTE:
Remember that, while the [B] button glows orange, any
mode or band changes will still be applied to the VFO-B
receiver, whether or not Dual Receive is engaged.

DUAL RECEIVE
Using Headphones for Dual Receive
To take advantage of dual reception, you will want to con-
nect stereo headphones to the PHONES jack. In addition
to the AF GAIN controls, headphone audio mixing can
also be configured as desired from Menu item “108 ROUT
HEADPHN”. Three audio mixing schemes are selectable
as follows:
SEPARETE: Audio from the VFO-A receiver is heard only
in the left ear, and VFO-B receiver audio
solely in the right ear.
CONBINE1: Audio from both VFO-A and VFO-B receiv-
ers can be heard in both ears, but VFO-B
audio is attenuated in the left ear and VFO-
A audio is attenuated in the right ear.
CONBINE2: Audio from both VFO-A and VFO-B receiv-
ers are combined and heard equally in both
ears (“Monaural” mode).
VFO Tracking Feature
You may lock VFO-B to track in unison with VFO-A when
the main tuning dial is adjusted. See page 83 for details.
Go to Menu item “038 GENE TRACK” to set the track-
ing function as follows:
OFF: VFO-A and VFO-B tune independently (Default)
BAND: Band Change operations will be applied to VFO-
A and VFO-B simultaneously.
FREQ: VFO-A and VFO-B tune in unison when The Main
Tuning dial is adjusted. However, VFO-B may
be adjusted separately.
Sideband Diversity Reception
Here you receive a single AM signal through the two re-
ceivers, 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 side-
bands 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 ste-
reo headphones connected to the front panel PHONES
jack.
Set VFO-A to either LSB or USB mode, and tune for
zero beat on the desired signal.
Press the [A
B] button to copy this mode and fre-
quency into VFO-B, then press the [MODE] button to
select the opposite sideband for VFO-A.
If using headphones, set the headphone mixing scheme
to the “CONBINE1” mode via Menu item “108 ROUT
HEADPHN”, and activate dual reception.
Adjust the [AF GAIN] knob(s) to balance the volume
of the two receivers.
If interference is present on one of the channels, you
may have to turn its [AF GAIN] knob to suppress that
channel (or press the green [RX] button to disable the
receiver with the sideband experiencing interference).
Otherwise, try changing the headphone audio mixing
scheme to “CONBINE2” or “SEPARETE” in the Menu
item “108 ROUT HEADPHN”, for different effects
(or try settings with similar effects, if you use an exter-
nal audio amplifier). Although you don’t get the “ste-
reophonic” effect in the monaural mode, the two sig-
nals are still mixed, offering the potential for much
better copy than in regular AM or even single-side-
band ECSS modes.
Page 44 FTDX5000 OPERATING MANUAL
Bandwidth Diversity Reception
This mode involves receiving the same signal through two
different bandpass filters. The frequency and mode of both
VFO-A and VFO-B are the same. VFO-A can be set up for
a wide bandpass, using the [WIDTH] knobs, and VFO-B
for a narrow bandpass, 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 external stereo speakers are recom-
mended for this mode. To set up the transceiver for band-
width diversity reception:
Select the desired mode on VFO-A.
Tune to the signal of interest.
Press the [A
B] button to copy this mode and fre-
quency into the VFO-B.
If using headphones, set the headphone mixing scheme
to the “CONBINE1” mode via Menu item “108 ROUT
HEADPHN”, and activate dual reception.
Adjust the [AF GAIN] knob(s) to balance the volume
of the two receivers.
Now try manipulating the [SHIFT] and [WIDTH]
knobs to observe the interesting effects of bandwidth
diversity.
CONVENIENCE FEATURES
DUAL RECEIVE
Polarity Diversity
Similar in concept to the bandwidth diversity just
described, another interesting capability of the
FTDX5000 dual reception, is the ability to use two
different antennas on the same frequency. For ex-
ample, 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. You may then transmit on which-
ever antenna is providing the strongest signal at the
moment (see the discussion below on Split Fre-
quency operation).

BAND STACK OPERATION
The FTDX5000 utilizes a triple band-stack VFO selection technique that permits you to store up to three favorite frequen-
cies 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 each VFO by successive, momentary presses of the [14] MHz band button. Each Amateur band key may
similarly have up to three frequency/mode settings applied. Both the VFO-A and VFO-B systems have their own, indepen-
dent, band stacks.
A typical setup, for the 14 MHz band, might be arranged
like this:
1. Program 14.025 MHz, CW Mode, then press the [14]
MHz band button;
2. Program 14.080 MHz, RTTY Mode, then press the [14]

RECEIVER OPERATION (FRONT END BLOCK DIAGRAM)
The FTDX5000 includes a wide range of special features to suppress the many types of interference that may be encoun-
tered 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.
Yaesu provides the optional RF-µTUNING Unit (Narrow-bandwidth High-Q RF Filter) for additional protection from
strong signal interference.
VRF (SEE PAGE 54)
On the 1.9 - 28 MHz amateur bands, Yaesu’s powerful
VRF (Variable RF Filter) preselector circuit provides ex-
cellent suppression of out-of-band interference. The pass-
band is much narrower than that provided by traditional
fixed bandpass filters.
R. FLT (IF Roofing Filters) (SEE PAGE 56)
On the VFO-A receiver, Roofing filters, in bandwidths of
15 kHz, 6 kHz, 3 kHz, 600Hz, and 300 Hz (optional in
some models), are provided in the 9 MHz First IF, right
after the first mixer. These filters provide narrow-band se-
lectivity to protect the following IF and DSP stages. The
15 kHz, 6 kHz, or 3 kHz filters are automatically selected
for typical operating modes, and may be manually changed
by the operator, if desired, for special operating circum-
stances.
The VFO-B receiver 40 MHz IF includes three Roofing
filters, with bandwidths of 15 kHz, 6 kHz, and 3 kHz.
CONTOUR Filter (SEE PAGE 58)
The DSP Contour filter is a unique capability of the
FTDX5000, providing either nulling or peaking of tunable
segments of the receiver passband. The Contour filter can
suppress interference, or excessive frequency components
on an incoming signal, or it can peak those tunable fre-
quency segments. The amount of nulling/peaking, and the
bandwidth over which it is applied, are adjustable via the
Menu.
IF SHIFT (SEE PAGE 60)
The passband center frequency response of the IF DSP
filtering may be adjusted using this control.
IF WIDTH (SEE PAGE 61)
The width of the IF DSP filtering may be adjusted using
this control.
IF NOTCH (SEE PAGE 63)
The IF Notch filter is a high-Q notch filter that can signifi-
cantly reduce, or eliminate, an interfering carrier. The Q
(sharpness) of the filter may be adjusted using the Menu.
DNR (DIGITAL NOISE REDUCTION) (SEE PAGE 64)
The DSP’s Digital Noise Reduction (DNR) feature uti-
lizes 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 64)
When multiple interfering carriers are encountered during
reception, the Digital Notch Filter can significantly reduce
the level of these signals.
AGC (SEE PAGE 67)
The AGC system is highly adaptable to changing signal
and fading characteristics, making reception possible un-
der the most difficult conditions.
SLOPED AGC (SEE PAGE 68)
Instead of limiting a wide range of audio output signals to
a fixed upper bound, the sloped AGC system actually al-
lows the audio output to rise, very gently, with ever-in-
creasing signal strength. This capability allows you to men-
tally separate signals, according to signal strength, in ad-
dition to slight frequency differences.
IF Filter Quality Adjustment (SEE PAGE 131)
The “Q” (quality factor) of the IF DSP filters may be ad-
justed using the Menu.
Variable IF Filter Shape Factor (SEE PAGE 131)
You may adjust the shape factor of the receiver IF DSP
filters using the Menu.

IPO (INTERCEPT POINT OPTIMIZATION)
The IPO feature allows the operator to optimize the characteristics of the receiver front end, depending on the current noise
level and the strength of incoming signals.
VFO-A IPO Setup
Press the [A] button to activate VFO-A receiver (The
[A] button will glow red).
Move the [IPO] knob up or down to set the desired
characteristic of the VFO-A receiver front end, per the
chart below.
AMP1: Amplifies the incoming signal, using a low
distortion RF preamplifier (normally, the IPO
is set to this position).
AMP2: Increases receiver sensitivity.
IPO1: Improves the IPO.
IPO2: Bypasses the RF preamplifier, yielding di-
rect feed to the first mixer. As a result, the
IPO is improved more.
The selected receiver RF preamplifier will be indicated
in the IPO column of the Block Diagram Display.
CONVENIENCE FEATURES
VFO-B IPO Setup
Press the [B] button to activate VFO-B receiver (The
[B] button will glow orange).

ADVICE:
On the 10 MHz and lower bands, it generally is not necessary to use any preamplifier at all; selecting the “IPO” position as
described above will increase the strong-signal-handling capability of the receiver, and usually result in more pleasant
reception due to reduced noise. If you can hear band noise with the preamplifiers disengaged, then a preamplifier is gener-
ally not needed.

ATT
Even with the IPO function on, extremely strong local signals or high noise can still degrade reception. In such situations,
you can use the [ATT] button to insert 6, 12, or 18-dB of RF attenuation in front of the RF amplifier.
VFO-A IPO Setup
Press the [A] button to activate VFO-A receiver (The
[A] button will glow red).
Move the [ATT] knob up or down to set the desired
attenuation level of the VFO-A receiver, per the chart
below.
OFF: Attenuator is Off
–6 dB: The incoming signal power is reduced by 6
dB (Signal voltage reduced by 1/2)
–12 dB: The incoming signal power is reduced by 12
dB (Signal voltage reduced to 1/4)
–18 dB: The incoming signal power is reduced by 18
dB (Signal voltage reduced to 1/8)
The selected attenuation level will be indicated in the
ATT column of the Block Diagram Display.
VFO-B IPO Setup
Press the [B] button to activate VFO-B receiver (The
[B] button will glow orange).
Move the [ATT] knob up or down to set the desired
attenuation level of the VFO-B receiver, per the chart
below.
OFF: Attenuator is Off
–6 dB: The incoming signal power is reduced by 6
dB (Signal voltage reduced by 1/2)
–12 dB: The incoming signal power is reduced by 12
dB (Signal voltage reduced to 1/4)
–18 dB: The incoming signal power is reduced by 18
dB (Signal voltage reduced to 1/8)
The selected attenuation level will be indicated in the
ATT column of the Block Diagram Display.
ADVICE:
If background noise causes the S-meter to deflect on clear frequencies, move the [ATT] knob 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 moving
the [ATT] knob to a greater 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 maxi-
mum sensitivity, so the IPO should be disabled and the [ATT] knob should be set to “OFF” by pressing the [ATT] knob. 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.
To quickly restore full signal strength through the At-
tenuator circuit, press the [ATT] knob in briefly to re-
store the ATT display to the “OFF”.

RF GAIN (SSB/CW/AM MODES)
The RF Gain controls permit manual adjustment of the receiver RF and IF stages gain levels, to account for noise and/or
signal strength conditions.
VFO-A Receiver RF GAIN Adjustment
The (VFO-A)[RF GAIN] knob should, be rotated, initially,
to the clockwise position. This is the point of maximum
sensitivity, and counter-clockwise rotation will gradually
reduce the receiver RF gain.
VFO-B Receiver RF GAIN Adjustment
The VFO-B receiver RF Gain operates identically to the
VFO-A receiver RF Gain.
Press the (VFO-B)[RX] button to engage the Dual
Receive operation. The (VFO-B)[RX] button will glow
green.
Always utilize the fully clockwise position of the (VFO-
B)[RF GAIN] knob as the starting point for operation.
ADVICE:
As the [RF GAIN] knob is rotated counterclockwise
to reduce the gain, the S-meter reading will rise. This
indicates that the AGC voltage being applied to the
receiver is increasing (which causes a reduction in re-
ceiver gain).
Rotating the [RF GAIN] knob 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 (VFO-B)[RF GAIN] knob operates identically to
the (VFO-A)[RF GAIN] knob. The effects of counter-
clockwise rotation of the VFO-B receiver RF Gain
control may be observed visually on the VFO-B S-
meter.
QUICK POINT:
Reception can often be optimized by rotating the [RF
GAIN] knob slightly counter-clockwise, to the point
where the S-meter stationary needles position is just
about the same as the receiver noise level. This setting
ensures incoming signals will be heard with minimal
noise. The S/N (signal to noise) of the receiver will be
improved, without so much gain reduction that weak
signals cannot be heard.
The RF GAIN control, along with the IPO and ATT
(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 ATT (at-
tenuator) features may be employed to provide pre-
cise, delicate adjustment of the receiver, and fully op-
timize performance.

USING THE VRF (VARIABLE RF FRONT-END FILTER)
The VRF system is a high-performance RF front-end preselector that has a high Q factor and low insertion loss. VRF
provides outstanding rejection of out-of-band signals, it can also significantly improve receiver performance when located

Page 55FTDX5000 OPERATING MANUAL
ADVICE:
The VRF system tuning is relatively broad, although it
is 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 adjust-
ments. However, if you have receiving problems asso-
ciated with a very strong signal, rotation of the [SE-
LECT] knob may help reduce the strength of the inter-
fering station, allowing improved reception of the de-
sired signal, if receiver overload was degrading recep-
tion.
The VRF Filter operational status will be memorized
independently on each VFO in the VFO stack.
You may select the display pattern shown in the SUB
DISPLAY window from three patterns via Menu item
“019 DISP SELECT”. See page 122 for details.
QUICK POINT:
The VRF filter utilizes high-quality coils and capacitors
that provide high Q, and yield a passband that is approxi-
mately 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,
the following adjustment steps are provided, if you wish
to skew the response in a particular direction to enhance
interference rejection even more. The actual “sound” of
the signal you are listening to will remain unchanged, how-
ever.

Narrow-band Roofing Filters of 15 kHz, 6 kHz, 3 kHz, 600 Hz, and 300 Hz 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. The roofing
filter 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 or CW band you may wish to select
a narrower filter. For example, the 3 kHz roofing filter for SSB operation, or the 600 Hz filter for CW.
:The 600 Hz roofing filter is only available on VFO-A. The 300Hz filter for VFO-A on the FTDX5000, is optional on
other versions.

TERMINOLOGY:
A “Roofing Filter,” as its name implies, places a “Roof”
over the receiver’s IF system bandwidth. This “Roof” pro-
tects the circuitry downstream from strong signal over-
load interference, just as a roof on a house protects the
contents from rain and snow.

VFO-A Contour Operation
Press the (VFO-A)[CONT/APF] button. The button
will glow red and the position of the “null” (or “Peak”)
of the contour filter will be indicated in the SUB DIS-
PLAY-II window. The (VFO-A)[SELECT] knob will
now function as the contour knob.
Rotate the (VFO-A)[SELECT] knob to achieve the
most pleasing audio reproduction of the incoming sig-
nal.
Press the (VFO-A)[CLEAR] button in briefly, to
quickly move the “null” (or “Peak”) position to center.
To cancel Contour tuning, press the (VFO-A)[CONT/
APF] button once more.
ADVICE:
The contour filter null or peaking level may be adjusted
using Menu item “112 RDSP CNTR LV”. The factory
default null setting is “–15” (dB).
The bandwidth over which the contour null or peaking
affect is applied may be adjusted using Menu item “113
RDSP CNTR WI”. The factory default setting is “10”.
You may select the display pattern shown in the SUB
DISPLAY window from three patterns via Menu item
“019 DISP SELECT”. See page 122 for details.
When the optional DMU-2000 Data Management Unit
is connected, the Audio Scope (on the DMU-2000 “Os-
cilloscope” page) is particularly useful when adjusting
the Contour controls. You can see the affect of the
Contour system on the signal levels, and the position
of the null/peak with respect to frequency components
of interest. On the Audio Scope, you may visually ob-
serve the affect of the Contour Controls while listen-
ing to the signal, this will help build your intuition on
how best to use Contour tuning in the future.
VFO-B Contour Operation
Press the (VFO-B)[CONT/APF] button. The button
will glow red and the current “null” (or “Peak”) posi-
tion of the contour filter will be indicated in the SUB
DISPLAY-III window. The (VFO-B)[SELECT] knob
will now function as the contour knob.
Rotate the (VFO-B)[SELECT] knob to achieve the
most natural-sounding audio reproduction of the in-
coming signal.
Press the (VFO-B)[CLEAR] button in briefly, to

QUICK POINT:
When adjusted aggressively, the steep slopes of the DSP
filtering can impart an unnatural sound to an incoming sig-
nal. Often, a narrow bandwidth is not the key to improved
copy. The incoming signal itself may have undesirable or
excessive frequency components, especially in the low fre-
quency range around 100-400 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 ob-
tainable with other filtering systems.

Refer to Figure “B”, and notice the initial position of
the contour when the [CONT] button is pushed. Ob-
serve the “indentation” in the receiver passband where
the contour filter is placing a low-Q “notch” (accord-
ing to the setting of Menu item “112 RDSP CNTR
LV”, as described on the previous page). Counter-
clockwise rotation of the [SELECT](contour) knob
causes the indentation to move toward a lower fre-
quency (to the left) within the passband, while clock-
wise rotation causes the indentation to move toward a
higher frequency (to the right) within the passband. By
removing the interference or unwanted frequency com-
ponents on the incoming signal, it is possible to make
the desired signal rise out of the background noise/
interference, and significantly enhance intelligibility.

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

ADVICE:
The Width and Shift features are the primary tools you
should use for best interference reduction. After narrow-
ing the bandwidth (width) and/or adjusting the center of
the passband (shift), the Contour control may also yield
further signal-enhancement benefits on the net residual
bandwidth. Additionally, the IF Notch Filter (see the next

from inside the receiver passband.
VFO-A IF Notch Operation
Press the (VFO-A)[NOTCH] button. The (VFO-
A)[NOTCH] button glows red, and the current “null”
(or “Peak”) position of the IF notch filter will appear

adjustment knob.
Rotate the (VFO-A)[SELECT] knob to adjust the cen-
ter frequency of the IF notch filter.
Press the (VFO-A)[CLEAR] button to move the “null”
position to center.
To switch the IF notch filter off, press the (VFO-
A)[NOTCH] button once more.
The affect of rotation of the [SELECT](notch)
knob on the performance of the IF notch filter is
depicted in Figure “A”. In Figure “B”, you can see
the notching effect of the IF notch filter as you ro-
tate the [SELECT](notch) knob to eliminate the
incoming interference.
VFO-B IF Notch Operation
Press the (VFO-B)[NOTCH] button. The (VFO-
B)[NOTCH] button glows red, and current “null” (or
“Peak”) position of the IF notch filter will be indicated
in the SUB DISPLAY-III window. The (VFO-
B)[SELECT] knob will now function as the notch
adjustment knob.
Rotate the (VFO-B)[SELECT] knob to adjust the cen-
ter frequency of the IF notch filter.
Press the (VFO-B)[CLEAR] button to move the “null”
position to center.
To switch the IF notch filter off, press the (VFO-
B)[NOTCH] button once more.
ADVICE:
The width of the IF notch null may be adjusted using
Menu item “110 RDSP NOTCH WI”. Both “Wide”
and “Narrow” selections are available, with “Narrow”
providing the least disruption of the “desired” signal.
You may select the display pattern shown in the SUB
DISPLAY window from three patterns via Menu item
“019 DISP SELECT”. See page 122 for details.
When the optional DMU-2000 Data Management Unit
is connected, the effect of the IF notch filter may be
observed using the Audio Scope (on the “Oscilloscope”
page). The notch will be seen as a “dip” in the noise
platform observed. What’s more, the “Waterfall” dis-
play may be used to observe the effect of the IF notch
filter, which will appear as a white area in the colored
background. The tuning rate for the IF notch is some-
what slow while you adjust the [SELECT](notch)
knob, so the use of the Waterfall display to confirm
proper adjustment is highly recommended.

AGC (AUTOMATIC GAIN CONTROL)
The AGC system is designed to help compensate for fading and other propagation effects, with characteristics that can be
of particular value on each operating mode. The basic objective of AGC is to maintain a constant audio output level once
a certain minimum threshold of signal strength is achieved.
VFO-A AGC Selection
Press the [A] button briefly to enable VFO-A (the LED
in the [A] button will glow red).
Move the [AGC] knob up or down to set the desired
receiver recovery time constant of the VFO-A receiver.
The selected recovery time will be indicated in the AGC
column of the Block Diagram Display.
Hold the [AGC] knob up or down for two seconds to
disable the AGC (for testing or weak-signal reception).
For most operations, we recommend using the “AUTO”
mode by pressing the [AGC] knob in briefly, or mov-
ing the [AGC] knob to set the ATT display to the
“AUTO” position.
VFO-B AGC Selection
Press the [B] button (the [B] button glows orange).

NOTE:
When the AGC receiver recovery time is set to “OFF”,
the S-meter will no longer deflect. Additionally, you
will likely encounter distortion on stronger signals, as
the IF amplifiers and the following stages are prob-
ably being overloaded.
Normally, the AGC “AUTO” selection is satisfactory
for most situations, but in the event of operation on a
crowded band where you wish to receive a weak sig-
nal, you may change the setting (to “FAST”, for ex-
ample). The AGC “AUTO” mode selections are:

ADVICE:
When a received signal becomes degraded due to pulse
type noise, you may improve signal readability by setting
Menu items “002 AGC FST HLD”, “004 AGC MID
HLD”, and “006 AGC SLW HLD” to “0 msec”.
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 gen-
erally do not recommend any changes to the AGC Menu
selections until you are thoroughly familiar with the per-
formance of the FTDX5000.
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, to maintain the output audio volume
at a more-or-less constant level. AGC also protects the
RF, IF, Audio, and DSP stages from overload, by limiting
the signal strength applied to circuits, regardless of the
input signal level.

SLOPED AGC Operation
In traditional AGC systems, the audio output from the transceiver becomes essentially constant, once the threshold
for AGC action is reached (usually several dozen dB above the no-signal
noise floor). The FTDX5000, however, includes an innovative Sloped AGC
system on the VFO-A receiver that allows the audio volume to rise and fall
slightly according to signal strength. Although the rise/fall slope is not dra-
matic, it is sufficient to allow you to use your ear to discern and separate
signals according to signal strength, not just audio frequency.

1. The operating mode is se-
lected using the [MODE]
buttons. The VFO (A or B)
to which the selection is ap-
plied is selected by the [A]
or [B] button located to the
upper left of the Main
Tuning Dial knob. Usu-
ally, the [A] button
glows red, signifying
that VFO-A is being ad-
justed. Similarly, press-
ing the [B] button will
cause the [B] button to
glow orange, signifying VFO-B adjustment. Press the
[A] or [B] button to select the desired VFO. Then press
the [LSB] or [USB] button briefly to select one of the
SSB modes. For AM operation, press the [AM/FM]
button repeatedly until the “ ” icon appears in the
display.
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 oper-
ating frequency. Alternatively, you may use the [UP]/
[DWN] scanning buttons on the MH-31B8 Hand Mi-
crophone to sweep up or down the current band.
3. Press the microphone’s PTT (Push To Talk) switch to
begin transmission; speak into the microphone in a
normal voice level.
ADVICE:
The “ ” indicator will light up in the frequency
display area, confirming that transmission is in
progress.
When transmitting in the AM mode, rotate the [RF
PWR] knob to set a maximum (carrier) power out-
put of 50 Watts.
4. In the SSB mode, adjust the micro-
phone amplifier gain to match the
microphone and your voice level.
set the [METER] switch to the
“ALC” position and close the PTT
switch. Speak into the microphone in
a normal voice level, and adjust the
[MIC] (gain) knob so that the ALC
voltage stays within the blue ALC
zone of the meter (up to 2/3 of full
scale deflection) on voice
peaks.
ADVICE:
The microphone gain of
the AM mode has been programmed at the factory
to a level that should be satisfactory for most situ-
ations. However, using Menu item “051 A3E MIC
GAIN”, you may set a different fixed value, or
choose the “MCVR” option, which then lets you
use the front panel [MIC] knob to set the micro-
phone gain in the AM mode. In this case, the [MIC]
knob should not be advanced to the point where
the ALC meter deflects. In many cases, the same
setting used on SSB will be satisfactory.
The relative Microphone Gain level will show for
3 seconds in the lower right corner of the Main
Display whenever the inner [MIC] knob is turned.
Alternately, the 3-second display feature may be
changed to show in the SUB DISPLAY-
III
win-
dow via Menu item “018 DISP INDI”. Addition-
ally, you may disable the 3-second display feature
via Menu item “017 DISP LVL IND” See page
122 for details.
5. Release the PTT switch at the end of your transmis-
sion. The transceiver will return to the receive mode.

ADVICE:
ALC meter deflection may be caused by excessive drive
power, and also by reflected power detected in the an-
tenna system. If the impedance presented to the trans-
ceiver is other than 50 Ohms, the ALC meter action
observed may not be related to the proper setting of
the [MIC] (gain) knob. Therefore, we recommend that
you make [MIC] gain adjustments into a dummy load
or an antenna system presenting an impedance very
close to 50 Ohms.
Rotate the [RF PWR] knob to set the desired power
output. Clockwise rotation of the [RF PWR] knob will
increase the power. The adjustment
range is between 10 Watts and 200
Watts, and you should always use the
minimum power necessary for main-
taining reliable communications.
The RF Power Output will show for 3 seconds in the
lower right corner of the Main Display whenever the
outer [RF PWR] knob is turned.
Alternately, the 3-second display feature may be
changed to show in the SUB DISPLAY-
III
window
via Menu item “018 DISP INDI”. Additionally, you
may disable the 3-second display feature via Menu item
“017 DISP LVL IND” See page 122 for details.
The analog PO meter indicates the average power out-
put level. SSB transmit average talk power is normally
10% to 50% of the peak power output. Voice charac-
teristics, microphone qualities, parametric equalizer
and compression settings affect actual talk power out-
put.
When performing transmitter tests for setup of the
[MIC] or [RF PWR] knobs, be sure to monitor the
frequency before transmitting, to avoid interference to
others who may already be using the frequency.
Four techniques for initiating Transmit/Receive con-
trol are provided on the FTDX5000. You may choose
the technique(s) that best suit your operating needs:
Pressing the microphone PTT switch will engage
the transmitter.
The rear panel PTT jack may be connected to a
foot switch or other manual switching device in
order to engage the transmitter.
Pressing the front panel [MOX] button will lock
the transmitter on. Press the [MOX] button again
to return to receive.
The VOX (Voice Operated Xmit) circuit will en-
gage the transmitter automatically when you speak
into the microphone. For VOX operation details,
see page 81.
Page 72 FTDX5000 OPERATING MANUAL
The Automatic Antenna Tuner (“ATU”) built into each FTDX5000 is crafted to ensure a 50-Ohm load for the final amplifier
stage of the transmitter. We recommend the ATU be used whenever you operate the FTDX5000.
ADVICE:
The ATU of the FTDX5000, being located inside the station, only adjusts the impedance presented to the transmitter at
the station end of your coaxial cable feedline. It does not “tune” the SWR at the antenna feedpoint itself. When design-
ing 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 FTDX5000 includes 100 memories for tuning data. Eleven of these memories are allocated, one per
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, allowing quick frequency change without the need to retune the ATU.
The ATU in the FTDX5000 is designed to match impedances within the range of 16.5 Ohms to 150 Ohms, correspond-
ing to an SWR of 3:1 or less on the HF amateur bands (6 meter amateur band: 25 Ohms to 100 Ohms, corresponding to
an SWR of 2:1 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.
ATU OPERATION
USING THE AUTOMATIC ANTENNA TUNER
1. Rotate the [RF PWR] knob fully clockwise (to the
right).
2. Use the Main Tuning Dial knob to set the radio to the
desired operating frequency within the Amateur band.
3. Press the [TUNE] button briefly to place the ATU in
the transmit line (no adjustment/tuning will occur yet).
The “ ” icon will appear in the display.
QUICK POINT:
The brief press of the [TUNE] button will turn the tuner
on, and the microprocessor will automatically select
the tuning point closest to the current operating fre-
quency.
4. Press and hold in the [TUNE] button for two seconds
to begin automatic tuning. The transmitter will be en-
gaged, and the “ ” icon will blink while tuning is
in progress. When the optimum tuning point has been
reached, the radio will return to receive, and the
“” icon will again glow steadily (instead of
blinking).
5. While tuning around the band using the Main Tuning
Dial knob, you will observe that the “ ” icon
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
each 10 kHz window, repeat step 4 (above) for each of
the windows. On bands like 1.8 MHz where the im-
pedance 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] button briefly. The “ ” icon will turn
off, confirming that the ATU has been turned off. In
the “Off” mode, the transceiver will be directly con-
nected to the coaxial cable connected to your antenna,
and it will operate based on whatever impedance is
present at the station end of the coax.
ADVICE:
The ATU circuit is located between the final amplifier and
the rear-panel antenna jack; reception is not affected by
the ATU.
QUICK POINT:
As shipped from the factory, only one ATU alignment
point is saved on each Amateur band. This was memo-
rized during the final alignment and performance veri-
fication stages on the production line.
The momentary flickering of the “ ” icon occurs
whenever you cross over into a new 10 kHz ATU
memory window.
NOTE:
Please check the operating frequency before beginning the
tuning process, to be sure you are not interfering with oth-
ers who may already be using the frequency.
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.

ABOUT ATU OPERATION
Figure 1 depicts a situation where normal tuning of the ATU has been successfully completed, and the tuning data has been
stored in the ATU memory. The antenna system as seen by the transmitter is shown.
In Figure 2, the operator has changed frequency, and the “ ” icon is shown. The operator presses and holds in the
[TUNE] button for two seconds to begin impedance matching using the ATU.
If a high SWR condition exists (above 3:1), corrective action must be taken in the antenna system to bring the impedance
closer to 50 Ohms. 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 antenna or feed system, and such failures can lead to the generation of spurious
signals causing TVI, etc.
About ATU Memories
SWR (Post-tuning) Less than 1.5:1
The tuning settings are committed to the ATU memory.
SWR (Post-tuning) Greater than 1.5:1
Tuning data will not be retained in memory. If you return to the same frequency, the tuning process must be repeated.
SWR (Post-tuning) Greater than 3:1
The “ ” icon will light up, and tuning settings, if achieved, will not be memorized. Please investigate and
resolve the high SWR condition before attempting further operation using this antenna.
