General Description
Hybrid SDR conguration inherited from the FTDX101 series
In addition to the narrow band SDR receiver that boasts awesome basic performance, the FTDX10 has a
hybrid SDR conguration utilizing an integrated direct sampling SDR receiver, which permits visualization
of the entire band spectrum in real time.
By adopting the hybrid SDR method, and utilizing the features of the direct sampling method, it is possible
to display a wide-view of the information in the entire band in real time, and improve the performance of
the complete receiving circuit with the narrow band SDR technology down conversion method.
Comes equipped with three types of roong lters
This transceiver is equipped with three types of roong lters for 500 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.
High-brightness TFT full-color display with touch-panel functionality
The FTDX10 is equipped with a 5-inch full-color TFT display. Operating functions, including the receiving
band noise and signal interference reduction tools, are graphically displayed. Even while involved in rig-
orous 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, a lter function display presents the state of the pass-band. In addition to
the operating 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.
Two selectable RF Stages amplify the desired signals from low band to
high band
RF amplifier AMP1, and AMP2 are low noise negative feedback RF amplifiers that may be selected 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.
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 e󰀨ective 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 e󰀨ective in making the desired signal rise out of the interference.

5
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 e󰀨ec-
tive, even when an interfering frequency is changing.
MPVD (MULTI PURPOSE VFO OUTER DIAL)
A large multi-functional ring is placed on the outside of the Main Dial. It is frequently used for the 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.
[FUNC] (function) knob
Simply press the function [FUNC] knob to easily select the setting menu, and then change the setting val-
ue. Quick response is possible even while operating. Assign a frequently used function or setting menu
and then you can easily change the setting just by turning the knob.
Reliable High-output Final Amplier Stage
FTDX10 power amplier utilizes a pair of RD70HUP2 transistors in a push-pull RF arrangement that deliv-
ers 100 watts of low-distortion, high-quality transmitter power.
SD memory card
An SD card slot on the front panel permits using a commercially available SD memory card for recording/
playback of received audio, for voice recording for transmission, to save the various operating settings,
saving memory contents, and screen capture (saving the display screen). The SD card is also used to up-
date the rmware.

Installation and Interconnections
Antenna Considerations
The FTDX10 is designed to connect to a 50 Ohm resistive impedance antenna at the Amateur operating
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 FTDX10 antenna connector for an SWR of 1.5 or less. Careful preparation of the anten-
na 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.
Antenna Connections
Carefully follow the illustration regarding the proper connection of antennas and coaxial cables.
To prevent damage from lightning, atmospheric electrical discharges,
electric shock etc., provide a good earth ground.
Use a short, thick, braided cable to connect the station equipment to the
buried ground rod (or alternative earth ground system).
Power Cable Connections
Carefully follow the illustrations regarding the proper connection of the DC power cable.
Use the DC power cable supplied with the FTDX10 to make the power connections to the power supply.

Installation guidelines
• Ensure adequate ventilation around the trans-
ceiver, to prevent heat build-up and possible re-
duction of performance due over heating.
• Do not install the transceiver in a mechanically
unstable location, or where objects may fall onto
it from above.
• To minimize the possibility of interference to
home entertainment devices, take all precaution-
ary steps including separation of TV/FM anten-
nas from Amateur transmitting antennas to the
greatest extent possible. Keep the transmitting
coaxial cables separated from cables connected
to home entertainment devices.
• The AC Power Cord connected to a socket-out-
let with earthing connection. A socket-outlet with
earthing connection shall connect to protective
earthing conductor.
