signal. A large heat sink is combined with the die cast aluminum
chassis for efficient heat dissipation. A cooling fan located beside
the final amplifier and the TX Low Pass Filter ventilates the heat away
from inside of the transceiver cabinet. This large axial flow fan is
mechanically isolated from the chassis to reduce vibration and noise.
The speed of the fan is continuously controlled by the temperature of
the PA amplifier; starting at 40 degree C.

CAT, USB AUDIO IN / OUT and USB TX Control (PTT, KEY and FSK)
Remote Control From A Distant Location
External
control (CAT) is possible using USB or Serial Port; this feature means
the FT DX 3000D can be remotetly controlled from a distant location!
Big TFT Full-Color Display For Superior Operability and Visibility
The
FT DX 3000D presents a wide view angle, high contrast LCD 4.3 inch TFT
impressive full color display that provides a convenient view of the
radio’s working functions. Superior operability is realized with this
convenient display. It permits excellent visibility from different
viewpoints. Even with the many FT DX 3000D features and functions, the
TFT display makes operation of the radio easy and comfortable.
• A Block Diagram Displays RX Signal Path
• Choose Analog Type or Bar Graph Meter
• Selectable analog type or bar graph type meter indication
• Separate Independent Frequency Display
• High Speed Spectrum Scope
• Bandwidth of the spectrum scope: 20kHz, 50kHz, 100kHz, 200kHz, 500kHz, or 1MHz
• TX and RX markers appear during “spit” operation
• Level Indicator
The function names and the setting levels of the following
functions are shown in the TFT main display when a function knob is
rotated: Clarifier, Microphone Gain, Speech Processor, SHIFT, WIDTH,
KEYER SPEED and CONTOUR
• AF-FFT Scope
An AF-FFT (Audio Frequency Fast Fourier Transform) scope is
built in. This AF-FFT function was first demonstrated in the FT DX 9000
series. With this Scope, the audio characteristics of the received
signals; the effect of adjusting the RX IF filter performance; and
utilizing the QRM rejection features, may be visually observed. It is
also possible to observe the TX audio characteristics of your own signal
while using the Monitor function. This is very effective for tuning
the parametric equalizer for voice characteristics and the microphone
audio.
• Spectrum Scope Memory
The Spectrum Scope screen can be stored or recalled with one
touch. Simultaneously the time information is recorded in the memory,
so that the difference in activity may be reviewed and compared,
depending on the seasons and times.
• Cursor Keys
Six keys that are used frequently in normal operation are
located at the left side of the TFT display. Other functions can be
operated by pressing the "SCOPE" key which changes the "Spectrum Scope
screen" to "Function Key Display screen". Even if the radio is turned
off, the last operated Key Function is memorized and highlighted.
Top Performing RF Front End
The
RF Front End circuit is the most important element because it
ultimately determines the HF Receiver performance. Our Yaesu
Engineering team has concentrated superior RF Engineering knowledge
into the design of the FT DX 3000D front end.
• Fifteen separate band pass filters (BPF) are used for
front end protection. This effectively reduces the undesired and out of
band signals.
• In the RF amplifier, the strong bipolar transistor
(2SC3357) is used. This transistor shows a low NF, and provides
superior intermodulation performance.
• The gain of each individual device is kept lower, and the
best optimized working point, with the lowest NF, is selected.
• A custom-designed wide coverage transformer, with less
magnetic saturation, is used for the I/O of the RF amplifier. This
construction makes the device performance better and provides excellent
multi signal performance.
Down Conversion Receiver and Powerful Narrow Bandwidth Crystal Roofing Filters
The
powerful narrow bandwidth crystal roofing filter enhances the receiver
multi-signal characteristics. The FT DX 3000D "Down Conversion"
receiver construction is similar to the FT DX 5000. The first IF
frequency is 9 MHz. This makes possible narrow bandwidth crystal
roofing filters (300 Hz, 600 Hz or 3 kHz) with a sharp shape factor
that creates amazing multi-signal receiving performance. The powerful
narrow bandwidth crystal roofing filter enhances the receiver
multi-signal characteristics.
• The 3 kHz roofing filter greatly improves SSB signal reception during close adjacent multi signal conditions.
• The 300 Hz* and 600 Hz roofing filters provide the best CW
receiving environment when the adjacent signals may affect the desired
signal reception.
*Note: 300 Hz filter optional
Effective QRM and QRN Rejection
Effective
QRM rejection is achieved from the FT DX 3000D IF DSP. The 32-bit high
speed floating decimal point DSP, TMS320C6727B (maximum 2800 MIPS/
2100 MFLOPS) made by Texas Instruments, is used for the IF section of
the FT DX 3000D. The signal is processed with the high speed 300 MHz
clock frequency.
• Proven IF WIDTH and IF SHIFT functions provide great QRM rejection performance
IF SHIFT
With the normal bandwidth, the pass band area can be moved
relatively, so that harmful signals are rejected from the pass band
IF WIDTH
By adjusting the band width, Interfering signals can be
removed from both sides of the pass band, without changing the pass
band position. The IF width function can make the pass band narrower
with one-touch. This function is effective in a pile-up or contest,
when the undesired signals are located just above and below the target
signal. When the IF Width knob is centered (click point), the pass band
width is 2.4 kHz in the SSB and CW modes. When “NAR” is turned on,
the minimum pass band becomes 50 Hz (200 Hz in the SSB mode), making it
possible to minimize the QRM with this sharp filter shape factor.
When the IF Width is turned clockwise from the center click point, the
pass band width can be extended wider, up to 4000 Hz. This may provide a
richer sounding and more comfortable QSO when in a local rag chew.
• CONTOUR
The CONTOUR function ideally tailors the received audio
signal without changing the bandwidth. The CONTOUR function varies the
outline of the IF DSP filter pass band characteristics, and the in-band
signal construction can be partially altered. Different from the IF
SHIFT or IF WIDTH, the special CONTOUR pass band, can reduce or peak
the desired signal, partially and continuously across the pass band.
This feature is effective especially when the undesired signal is close
to the center frequency.
• Digital Noise Reduction (DNR) by DSP
The installed digital noise reduction circuit provides 15
separate parameters. The noise reduction constants may be set to the
optimal working point by varying the 15 step parameters according to
the actual noise within the HF band. The desired signal components are
peaked and the random noise components are effectively cancelled.
• IF NOTCH
This high Q circuit has steep attenuation characteristics of
70dB or more. Effective removal of a strong beat signal is obtained.
The damping characteristics can be switched to wide or narrow band
width, and the attenuation level may be adjusted in the Setting Mode
Menu. Interfering signals may be attenuated, while minimizing the
impact on the received signal.
• Digital Notch Filter (DNF) (AUTO NOTCH)
The Digital Notch Filer (DNF) is a feature that
automatically follows the interfering heterodyne signals, even if there
are more than one, and even if the beat frequency changes with time.
This is effective in removing jamming signals.
• CW APF (Audio Peak Filter)
In the CW mode, the APF (Audio Peak Filter) function has an
audio peak at the signal frequency; this improves the S/N and increases
the readability of the CW signal. The APF peak frequency can be finely
aligned.
Very Low Noise Floor - Terrific Signal to Noise Ratio
The
S/N ratio (signal-to-noise ratio) of the local signal that is injected
into the 1st IF mixer is one of the most important factors for
improving the receiver properties in the ultra-multi-signal
environment.
In the FT DX 3000D, the combination of it's high stability
and high accuracy 40 MHz TCXO (± 0.5ppm, -10 °C ~ +60 °C), and it's DDS
create the fundamental frequency of this radio, and is locked to the
PLL-IC and VCO directly. This circuit construction and method creates
the highest quality local signal, with superior S/N performance. This
means the receiver noise floor is kept lower, and realizes the best
blocking dynamic range at 2 kHz IP3 performance.
Three IPO Settings - Best Signal Reception During Changing Band Conditions
3-step
IPO settings permit the operator to select the most appropriate gain
for best signal reception. This variety of selections provides superior
receiver performance and the best possible communications with
changing band conditions.
The IPO (Intercept Point Optimization) is selected by a
control switch located on the front panel. The IPO selection determines
the gain of the RF amplifier. The gain setting is very effective in
optimizing the receiver performance, depending on the antenna and the
communication propagation conditions. The IPO, the ATT and one stage of
the RF amplifier are used to optimize the signal levels that are sent
to the mixer. This is especially important for HF low-band operation.
The "AMP 1" uses one RF amplifier stage, and maintains a better balance
between the sensitivity and the receiver performance (the gain is
around 10 dB). In addition, "AMP 2" uses two stages of the RF
amplification and can obtain higher sensitivity (the gain is around 17
dB); something particularly important on the 6 and 10 meter bands.
High Quality Audio With Punch
The
modulation circuit of the FT DX 3000d utilizes digital variation
operational modulation, which creates ideal high quality transmission
audio.
• Microphone Amplifier that includes Parametric Equalizer
The modulation circuit of the FT DX 3000D utilizes the
digital variation operational modulation type, which creates ideal high
quality transmission audio. This radio has a parametric equalizer that
makes possible versatile adjustment of the TX audio quality by
aligning the TX band audio spectrum. The parametric equalizer can alter
the Low, Mid and High part of the audio separately. This three stage
parametric equalizer can generate high quality TX audio sound because
it can be tuned in detail…without sacrificing the audio dignity.
• IF DSP Speech Processor – DX’er and Contester Proven
The SSB Speech Processor uses IF digital signal processing
to increase the intelligibility of the transmitted signal during weak
signal crowded conditions. The DSP increases the average power of the
important speech spectrum components and reduces the TX power of the
less significant components. Adjust the compression level in the Menu
Mode to adapt the transmitted SSB signal to best suite your voice
characteristics, the situation, propagation conditions and pile-up
demands.
Three Antenna Inputs
Three antenna connectors are available on the FT DX 3000D Rear Panel.
• Having multiple antenna selections is an especially effective feature for DX and Contest operating.
• Antenna connection selections memorized and recalled when changing bands.
• The "ANT 3" input can be set for the "RX Only" antenna.

5 Digital Voice Messages
Each memory channel is capable of storing up to 20 seconds of audio using the optional DVS-6.
RX Output
The
"RX Output" connector on the FT DX 3000D Rear Panel accesses the
signal from the receiver RF amplifier. The signal can then be output
to an external receiver for in-band simultaneous receiving.
Optional Fully-Automatic ยต-Tuning Kit
The
u-Tuning Kit that was developed for the FT DX 9000, is optionally
available for use with the FT DX 3000D. No other Amateur Radio radio
manufacturer offers a comparable device that may improve your DXing
performance in some challenging operating situations.
A large diameter 28 mm inductor, with an adjustable ferrite
magnetic material (Ni-Zn ferrite) core, is combined, with a high
resolution and high torque stepping motor to automatically find the
resonance point. By inserting these tuning units prior to the RF front
end of the receiver, the IP3 points are improved by around 4 dB. Three
individual tuning units are available covering frequencies from 1.8
MHz through 14 MHz. Many FT 950, FT 2000/D, FT DX 5000 and FT DX 9000
Yaesu customers have used them and found them especially effective for
use on the Lower Bands.
