General Description
Hybrid SDR conguration
In addition to the narrow band SDR receiver that boasts awesome basic performance, the FTDX101D has
a hybrid SDR conguration utilizing an integrated direct sampling SDR receiver, which permits visualiza-
tion of the spectrum of the entire band in real time.
By adopting the hybrid SDR method, and utilizing the features of the direct sampling method, wide-view
displays of the information in the entire band in real time, and improved performance of the entire receiv-
ing circuit with the narrow band SDR technology down conversion method are possible.
Comes equipped with three types of roong lters
This transceiver is equipped with three types of roong lters for 600 Hz, 3 kHz and 12 kHz bandwidths.
These narrow band lters are especially useful on a very crowded band during contests, because they
can dramatically attenuate powerful out-of-band signals in the rst IF stage, and thus reduce their impact
in the second stage. Further, the excellent dynamic range and IP3 characteristics optimize the processing
of all signals ranging from faint to powerful.
Adopts 3DSS/Hybrid Dual SDR Display
In addition to the conventional waterfall display, a 3DSS (3 Dimensions Spectrum Stream) image method
has been newly adopted. The 3DSS image uses the horizontal axis (X axis) for frequency, the vertical
axis (Y axis) for signal intensity, and the Z axis for time. Compared to the conventional waterfall method,
the signal strength is displayed in three dimensions as well as in color, recognition of changes in the band
conditions is instant, convenient and intuitive.
The 3DSS waterfall display has a choice of the mono display that displays only the MAIN frequency band;
or the dual display that illustrates both the MAIN and SUB frequency bands.
The Hybrid Dual SDR Display presents two SDR outputs, narrow band SDR and direct sampling SDR,
combined the same screen. Since the display color of each SDR output can be changed, the band re-
ceived by the narrow band SDR receiver can be viewed while also observing the condition of the entire
band.
High-brightness TFT full-color display with touch-panel functionality
The FTDX101D is equipped with a 7-inch full-color TFT display. Operating functions, including the receiv-
ing band noise and signal interference reduction tools, are graphically displayed. Even while involved in
rigorous operations, such as DXpeditions and contests, the operator may instantly grasp the status of
each function.
Filter Function Display monitors the status of the passband
In the upper part of the display, an S meter and a lter function display present the state of the pass-band.
They are arranged independently for the MAIN Band and SUB Band respectively. In addition to the oper-
ating state of the interference removal functions, the lter function information is displayed. Not only can
you grasp the operating status of WIDTH, SHIFT, NOTCH and CONTOUR at a glance, you can also view
the status of the RF spectrum in the passband.
RF Pre-selector, Continuously Variable RF, & VC-TUNE
The newly developed VC tuning circuit drives a variable capacitor with a high-precision stepping motor
and is comparable with a µ-Tuning mechanism, it achieves remarkable interference reduction character-
istics with signicant downscaling and maximum attenuation of -70 dB. When compared with the conven-
tional preset method, which switches a coil and a capacitor with a relay, the high-precision stepping motor
continuously follows the frequency inside the pass-band, there is no sense of discomfort as there is with
relay switching. Even when there are multiple powerful signals in the band, ne adjustment to the optimal
tuning point is possible.
Two selectable RF Stages amplify the desired signals from low band to
high band
Push-pull RF amplier AMP1, and AMP2 are low noise negative feedback RF ampliers that may be se-
lected or combined in series as is needed for various low-band, high-band, frequency and noise conditions.
In addition, the IPO (Intercept Point Optimization) function maximizes the dynamic range and enhances
the close multi-signal and inter-modulation characteristics of the receiver. The inuence of strong broad-
casting stations, especially in the low bands, can be minimized.

5
WIDTH and the continuously variable Bandwidth SHIFT features per-
mit elimination of interfering signals
The WIDTH feature allows the bandwidth to be narrowed by rotating the WIDTH knob. The SHIFT feature,
can eliminate interference in one side of the passband. Often, weak signals disappear due to interfering
signals (including pile-ups). The interfering signals may be extracted, leaving only the desired signal, be-
cause of the unique DSP sharp ltering characteristics.
CONTOUR feature is renowned for effective noise reduction
Rather than using the DSP extremely sharp attenuation characteristics, the CONTOUR circuit provides
gentle shaping of the DSP passband lter, and can thus attenuate or peak bandwidth components in seg-
ments. The interfering signal can be naturally shaped without having part of the signal suddenly disrupted.
The contour function is very effective in making the desired signal rise out of the interference.
DNR (Digital Noise Reduction) by DSP digital processing
The incorporated digital noise reduction circuit may be set to the optimal working algorithm by varying the
15 step parameters according to the noise type.
NOTCH feature can eliminate an unwanted heterodyne, and the DNF
feature can instantly attenuate multiple heterodyne signals
When interfering beat signals are present in the receiver passband, the IF NOTCH feature can signicant-
ly eliminate a narrow portion of the passband and remove the interfering signal. Moreover, when there are
multiple interfering signals, the DSP DNF (Digital Notch Filter) Automatic Tracking System can be effec-
tive, even when an interfering frequency is changing.
ABI (Active Band Indicator)
Band keys are arranged in a row at the top above the main dial so that the operation status of the MAIN
and SUB Bands can be checked at a glance. The band selected on the MAIN side is white, the band se-
lected on the SUB side is blue. The white and blue correspond to the colors of the MAIN and SUB Band
Switches.
When transmitting, the LED on the transmission band turns red. It is possible to instantly distinguish which
band is transmitting and thus prevent erroneous operation.
Additionally, when the band key is pressed and held, the LED lights up in orange, so you can use this to
display a band connected with an antenna, display a band to be operated with a DXpedition, etc., or as a
MEMO.
MPVD (MULTI PURPOSE VFO OUTER DIAL)
A large multi-functional ring, cut from high-grade aluminum is placed on the outside of the Main Dial. It is
frequently used for the SUB VFO dial, VC tune, Clarier or a CS (Custom select) function. The operator
may assign favorite functions to the MPVD that can then be operated with one touch. The ring can be
used to adjust important functions without releasing your hand from the Main Dial. This feature can be a
great convenience in the ever-changing shortwave radio communications.
Reliable High-output Final Amplier Stage
The nal amplier utilizes a pair of RD100HHF1 transistors in a push-pull RF arrangement that delivers
100 watts of low-distortion, high-quality transmitter power.

Installation and Interconnections
Antenna Considerations
The FTDX101D is designed to connect to a 50 Ohm resistive impedance antenna at the Amateur oper-
ating frequencies. Select an appropriate antenna (dipole antenna, YAGI antenna, cubical quad antenna,
etc.) that is suitable for the chosen operation and bands.
Construct the antenna and coaxial cable, or use a suitable antenna tuner, to maintain the impedance
presented to the FTDX101D antenna connector for an SWR of 1.5 or less. Careful preparation of the an-
tenna and/or tuner will permit maximum performance, and protect the transceiver from damage.
High transmitter RF voltages may be present on the antenna; install it so it will not be easily touched when
in operation.

ming signals that cannot be removed even with the BPF. If there is
no disturbing signal, turn it OFF. Operation is performed with the
outside MPVD ring of the Main Dial.
BPF (Band Pass Filter)
BPF is selected automatically. When a frequency band is selected
on the front panel, the BPF (Band Pass Filter) for that band is auto-
matically connected to the antenna circuit.
Use the ROOFING FILTER
Roofing filters attenuate strong signals that are outside of the de-
sired passband after converting to the 9MHz IF.
The roofing filter can attenuate unwanted frequency components.
Touch [R.FIL] on the TFT screen to select the 3kHz lter for SSB,
the 1.2kHz lter or the 600Hz lter for CW. An optional 300Hz lter
is also available.
Use DSP interference removal functions
DSP interference removal functions include IF SHIFT, IF WIDTH, IF
NOTCH, APF, CONTOUR, and DNR.
Use these functions to adjust for comfortable reception while listen-
ing to the received audio.
To change the sound quality of the received audio, use the CON-
TOUR function to easily improve the sound quality with high and
low frequency cut or emphasis.

Important setting items when receiving
ANT (Switching the Antenna)
The currently used antenna terminal number
(“ANT 1” “ANT 2” “ANT 3 / RX”) is displayed.
After touching ANT, touch the desired number.
The antenna can be set separately for each oper-
ation band.
The antenna terminal “ANT 3 / RX” can be set
to “Receive Only” (Set Menu: “ANT 3 SELECT”
page 97).
ATT (Attenuator)
Displays the current ATT (Amount of receive input
signal attenuation).
When the desired signal is extremely strong or
the noise level is high on a low frequency band,
activate the attenuator to reduce the incoming
signal or noise from the antenna.
After touching [ATT], touch the desired attenua-
tion amount.
The attenuator is set independently for each op-
eration band.
OFF Attenuator is Off
6dB The incoming signal power is reduced by
6dB (Signal voltage reduced to 1/2)
12dB The incoming signal power is reduced by
12dB (Signal voltage reduced to 1/4)
18dB The incoming signal power is reduced by
18dB (Signal voltage reduced to 1/8)
• If the noise level is high or the received signal
is extremely strong, the incoming signal level
can be suppressed with the IPO/ATT settings.
If the S-meter fluctuates S-3 or more in the
noise level, or the received signal is extremely
strong and it causes a high S-meter indication
(+20dB or more), activate the attenuator.
• Since IPO does not only attenuate the incom-
ing signal, but also improves the cross mod-
ulation characteristic, try to activate the IPO
first. If the signal is still strong, also use the
ATT. In this way, you can attenuate the incom-
ing signal and noise effectively.
IPO
The IPO (Intercept Point Optimization) function
can establish the gain of the RF amplier section
to accommodate the connected antenna and the
received signal conditions. IPO can be selected
from three operating conditions.
AMP1: One stage RF amplifier is connected.
This is a well-balanced operation of re-
ceiver sensitivity and characteristics (Ap-
proximately 10 dB gain).
AMP2: Two RF amplifiers are connected in se-
ries to give top priority to sensitivity (Ap-
proximately 20 dB gain).
IPO: The received signal is input to the IF mix-
er without passing through the RF ampli-
fier. This can greatly improve receiving,
especially in the harsh low band signal
environment.
After touching [IPO], touch the desired operating
condition.
• IPO is set independently for each operation
band.
• Normally, select “AMP1”.
• The IPO can not only attenuate the input sig-
nal but also improve the intermodulation char-
acteristics. It is most effective to operate the
IPO rst, and then use the ATT if the signal is
still too strong. The noise level can be attenu-
ated and S/N greatly improved.
