Press and hold in this switch for two seconds to turn
the transceiver on, after first setting the rear panel
[MAIN 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 [MAIN
POWER] switch is set to the “O” position, the front
panel [POWER] switch will not function.
ADVICE:
ˆ If you press this switch briefly while the transceiver
is turned on, the transceiver’s audio will be muted
for three seconds.
ˆ This is the actual power On/Off switch for turning
on the transceiver. When the rear panel [MAIN
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 [MAIN POWER] switch, please see the
discussion on page ??.
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 VFO-A and 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 switch-on.
CAT Indicator
This LED indicator will flash red when the transmit
and receive serial CAT command signals are being exchanged.
ADVICE:
You may disable the LED function (flashes in conjunction with CAT command) via Menu item “031 GEnE
CAT IND.” See page ??? for details.

This button enables the transmit monitor in all modes.
While activated, the “
” icon appears in the display. Adjustment of the Monitor level is accomplished
using the [MONI] knob.
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.
[MOX] Switch
Pressing this button engages the PTT (Push to Talk)
circuit, to activate the transmitter (the LED inside this
button will glow red). 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 (the LED
inside this button glows red) 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
This button enables automatic voice-actuated 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. By proper adjustment of
these controls, hands-free voice-actuated operation is
possible.
[TUNE] Switch
This is the on/off switch for the FTDX5000’s Automatic Antenna Tuner.
Pressing this button momentarily places the antenna
tuner in line between the transmitter final amplifier and

in the display. Adjustment of the Processor level is accomplished using the [PROC] knob.
ADVICE:
ˆ The Speech Processor is a tool for increasing the
average power output through a compression technique. However, if the [PROC] knob 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).
ˆ When the optional DMU-2000 Data Management
Unit is connected, you may use the Audio Scope/
Oscilloscope page to help you adjust the setting of
the compression level of the Speech Processor for

version), and the selected bandwidth appears in the
R.FLT column of the Block Diagram Display on the
display.
ADVICE:
ˆ Press this knob briefly to select to “AUTO” for
quick selection.
ˆ 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.
[IPO] (INTERCEPT POINT OPTIMIZATION) Switch
Move this knob up and down to select the optimum
front end characteristics of the receiver circuit for a
very strong-signal environment. Available selections
are “AMP 1”, “AMP 2”, “IPO 1”, or “IPO 2”.

utilized on the 14 MHz and higher bands.
ˆ 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 from (for example)
USB to CW, use the Menu item “063 A1A
FRQDISP,” described on page 122.

CLAR (CLARIFIER) OPERATION ON VFO-A
The [RX CLAR/FAST], [CLEAR], [TX CLAR/LOCK] buttons and [CLAR(VFO-B)] knob are used to offset either the
receive, transmit, or both frequencies from their settings on the VFO-A frequency (the Clarifier does not affect the VFO-B,
however). 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; frequency step depends on the Main Tuning
Dial knob) without actually retuning, and then to activate it via the Clarifier’s [RX CLAR/FAST] and [TX CLAR/LOCK]
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:

DUAL RECEIVE
The FTDX5000 is capable of simultaneous reception on the same amateur band, using the VFO-A and 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 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 DISPLAYI (for VFO-B).
2. Adjusting the volume:
To adjust the VFO-A audio level, rotate the (VFOA)[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 volume level.

while USB is utilized on the 14 MHz and higher bands.
ADVICE:
ˆ 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 “104 ROUT HEADPHN” (see
page 124).
ˆ 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 from (for example) USB to CW, use the Menu
item “062 A1A FRQ DISP”, described on page 122.
ˆ When operating on the FM mode on the VFO-B receiver, rotate the (VFO-B)[SQL] knob 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 (VFO-B)[SQL]
knob will degrade the ability of the receiver to detect
weak signals. Adjustment of the VFO-A squelch is accomplished using the (VFO-A)[SQL] knob.
NOTE:
Please remember that, while the [B] button glows orange,
any mode or band changes will still be applied to the VFOB receiver, whether or not Dual Receive is engaged.

Using Headphones for Dual Receive
Sideband Diversity Reception
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 item “104 ROUT
HEADPHN”. Three audio mixing schemes are selectable
as follows:
Here you receive a single AM signal through the two receivers, each receiving the opposite sideband. Skywavepropagated 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.
SEPARETE
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
CONBINE1: Audio from both VFO-A and VFO-B receivers can be heard in both ears, but VFO-B
audio is attenuated in the left ear and VFOA audio is attenuated in the right ear.
CONBINE2
CONBINE2: Audio from both VFO-A and VFO-B receivers are combined and heard equally in both
ears (“Monaural” mode).
FTDX5000 OPERATING MANUAL
To tune in a signal using this mode, you should have stereo headphones connected to the front panel PHONES
jack.
ˆ Set the VFO-A to either LSB or USB mode, and tune
for zero beat on the desired signal.
ˆ Press the [AX B] button to copy this mode and frequency into the VFO-B, then press the [MODE] button to select the opposite sideband for the VFO-A.
ˆ If using headphones, set the headphone mixing scheme
CONBINE1
to the “CONBINE1
CONBINE1” mode via the Menu item “104
ROUT HEADPHN”, and activate dual reception.
ˆ Adjust the [AF GAIN] knob(s) to balance the volume
of the two receivers.
ˆ 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
CONBINE2
SEPARETE
scheme to “CONBINE2
CONBINE2” or “SEPARETE
SEPARETE” in the Menu
item “104 ROUT HEADPHN”, 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.
Page 43
CONVENIENCE FEATURES
DUAL RECEIVE
Bandwidth Diversity Reception
This mode involves receiving the same signal through two
different bandpass filters. The frequency and mode of both
the VFO-A and VFO-B are the same. The VFO-A can be
set up for a wide bandpass, using the [WIDTH] knobs,
and the 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 an external stereo speaker are recommended for this mode. To set up the transceiver for
bandwidth diversity reception:
ˆ Select the desired mode on the VFO-A.
ˆ Tune to the signal of interest.
ˆ Press the [AX B] button to copy this mode and frequency into the VFO-B.
ˆ If using headphones, set the headphone mixing scheme
CONBINE1
to the “CONBINE1
CONBINE1” mode via the Menu item “104
ROUT HEADPHN”, and activate dual reception.
ˆ Adjust the [AF GAIN] knob(s) to balance the volume
of the two receivers.
ˆ Now try manipulating the [SHIFT] and [WIDTH]
knobs to observe the interesting effects of bandwidth
diversity.
Page 44
Polarity Diversity
Similar in concept to the bandwidth diversity capability just described, another interesting capability of the FTDX5000 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 oppositepolarization 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).

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 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.
We provide the RF-TUNING Unit (Narrow-bandwidth High-Q RF Filter) for the option.
VRF (SEE PAGE 53)
IF NOTCH (SEE PAGE 58)
On the 1.9 - 28 MHz amateur bands, 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.
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.
R. FLT (IF Roofing Filters) (SEE PAGE 54)
On the VFO-A receiver, three automatically-selected Roofing filters, in bandwidths of 15 kHz, 6 kHz, 3 kHz, 600
Hz, and 300 Hz are provided in the 9 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.
DNR (DIGITAL NOISE REDUCTION) (SEE PAGE 59)
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 59)
When multiple interfering carriers are encountered during
reception, the Digital Notch Filter can significantly reduce
the level of these signals.
The VFO-B receiver’s 40 MHz IF includes a fixed Roofing filter, with a bandwidth of 15 kHz, 6 kHz, and 3 kHz.
AGC (SEE PAGE 62)
CONTOUR Filter (SEE PAGE 55)
The AGC system is highly adaptable to changing signal
and fading characteristics, making reception possible under the most difficult conditions.
The DSP Contour filter is a unique capability on the
FTDX5000, 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 56)
The passband center frequency response of the IF DSP
filtering may be adjusted using this control.
IF WIDTH (SEE PAGE 57)
The width of the IF DSP filtering may be adjusted using
this control.
SLOPED AGC (SEE PAGE 63)
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 125)
The “Q” (quality factor) of the IF DSP filters may be adjusted using the Menu.
Variable IF Filter Shape Factor (SEE PAGE 125)
You may adjust the shape factor of the receiver IF DSP
filters using the Menu.

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 more 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
OFF
sensitivity, so the IPO should be disabled and the [ATT] knob should be set to “OFF
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.

and/or signal strength conditions at the moment.
VFO-A Receiver’s RF GAIN Adjustment
VFO-B Receiver’s RF GAIN Adjustment
The (VFO-A)[RF GAIN] knob should, initially, be rotated to the fully clockwise position. This is the point of

VFO-A receiver’s RF Gain.
ˆ Press the (VFO-B)[RX] button to engage the Dual

ADVICE:
ˆ 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 receiver gain).
ˆ 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.
ˆ The (VFO-B)[RF GAIN] knob operates identically to
the (VFO-A)[RF GAIN] knob. The effects of counterclockwise rotation of the VFO-B receiver’s RF Gain
control may be observed visually on the VFO-B Smeter.
FTDX5000 OPERATING MANUAL
QUICK POINT:
ˆ Reception frequently can be optimized by rotating the
[RF GAIN] knob 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] knob. This setting ensures that excessive gain is not being utilized,
without so much gain reduction that incoming signals
cannot be heard.
ˆ The RF GAIN control, along with the IPO and
ATT(enuator) 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(enuator) features may be employed to provide
precise, delicate adjustment of the receiver gain so as
to optimize performance fully.

ADVANCED INTERFERENCE-SUPPRESSION FEATURES: RF FRONT END
The FTDX5000 includes an unmatched array of RF selectivity-enhancing features. Please study the material below carefully, so as to understand the various features completely.
USING THE VRF (VARIABLE RF FRONT-END FILTER)
The VRF system is a high-performance RF front-end preselector that has high Q factor and low insertion loss. VRF provides outstanding rejection of out-of-band signals, and can significantly improve reception in tough co-location operations
such as a contest or DX-pedition. The FTDX500’s VRF system affects the 1.8 - 28 MHz amateur bands only.

USING THE VRF (VARIABLE RF FRONT-END FILTER)
ADVICE:
ˆ 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 [SELECT] knob
may help reduce the strength of the interfering station,
allowing improved reception of the desired signal if
overload was degrading reception.
ˆ The VRF Filter operational status will be memorized
independently on each VFO in the VFO stack.
FTDX5000 OPERATING MANUAL
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, the following adjustment steps are provided, if you wish to skew
the response in a particular direction so as to enhance interference rejection even more. The actual “sound” of the

ˆ When the optional DMU-2000 Data Management Unit
is connected, the Audio Scope (on the “Oscilloscope”
page) is particularly useful when adjusting the Contour control. Not only can you see the effect of the
null/peak of the Contour system, but you also can see
the position of the null/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.

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 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 obtainable with other filtering systems.
