FEATURES
Superior Visibility and Logical, Fatigue-reducing Panel Layout
The front panel layout is logically crafted, with the large-aperture main frequency display squarely in the middle of the front panel; the
two large S-meters to the left providing instant recognition of signal strength.
Just as in an aircraft cockpit, the panel meters and the LCD display are canted slightly toward the center for maximum visibility.
Large, Multi-colored VFD Fluorescent Display
A proprietary, high-brightness VFD (fluorescent) display is incorporated in the FT DX 9000MP, providing outstanding visibility and easy
reading of the important frequency information, whether in dim or bright lighting environments.
Function-Indicating LEDs
The many function status indications on the front panel are clearly identified by the operator, thanks to the innovative multi-color LEDs
incorporated in design. A Red LED indicates that a function is engaged on the Main Band, while an Orange LED shows that the function
is engaged on the Sub Band.
Indirect Illumination
For ease of nighttime operation, the controls on the front panel are indirectly illuminated, thanks to carefully-positioned lamps in the
frame underneath the meters and the Band switch.
Aluminum-Die-Cast Oversized Main Tuning Dial
The Main Tuning Dial is a large-diameter (3.2”/81 mm) dial directly coupled to the magnetic rotary encoder which drives the HRDDS
via microprocessor control. Its heavy weight (7 oz./200 g) and quality mounting and construction provide a smooth “flywheel” effect
during operation, ideal for quick cruising up and down a band.
Oversized Knobs for Most Important Functions
The concentric AF/RF Gain, SHIFT/WIDTH, and CLAR/VFO-B knobs are conveniently located at the right-bottom side of the Front
Panel, for ease of access to these important controls.
World’s First 400 MHz HRDDS Local Oscillator
So as to optimize spurious-free dynamic range in a multi-signal environment, Yaesu’s engineers have introduced the world’s first
HRDDS (High Resolution Direct Digital Synthesizer) as the first local oscillator of the FT
DX 9000MP. Dividing directly from this high
frequency, this local oscillator design ensures extraordinarily low noise, resulting in improved weak-signal reception even on a crowded
band during a weekend contest.
New-design Large-area OCXO Reference Oscillator
Serving as the master reference oscillator for the transceiver, the 10 MHz OCXO (Oven Controlled Crystal Oscillator) is a large-area (50
x 50 mm/2” x 2”) oven-stabilized oscillator operating at high temperature, for industry-leading frequency stability rated at 0.03 ppm
over the temperature range –10° to +60° C (–14° to +140° F).
Triple-conversion Design with Optimized Gain Distribution
Taking into account the most efficient transceiver design concept consistent with high performance we have adopted a triple-conversion
IF structure, utilizing a first IF at 40 MHz, a second IF at 455 kHz, and the third IF at 30 kHz (for FM, the 3rd IF is at 24 kHz). Gain
distribution through all stages is carefully optimized, for preservation of high system dynamic range.
Ultra-strong Receiver Front End
YAESU’s outstanding RF-stage filtering establishes a clean performance that allows the rest of the receiver to perform at a high level. By
reducing the ingress of energy from very strong sources like Shortwave Broadcast, local AM/FM/TV stations, and other signal sources,
the overall purity of the spectrum delivered to the RF Amplifier first mixer, and subsequent stages is maintained, and the system
Blocking Dynamic Range is also enhanced.
Compact Flash (CF) Card for Data Management
A Compact Flash card is supplied with every FT DX 9000MP, for preservation of transceiver configuration settings along with Log Book
archival data.
Professional-Grade Cannon (XLR) Microphone Connector
The FT DX 9000MP incorporates, for the first time ever in an Amateur Radio transceiver, a balanced-input “Cannon” (XLR) microphone
connector on the front panel, for use with studio-grade professional microphones. A round 8-pin microphone jack is also provided on the
rear panel.
Two High-precision Analog Meters (Page 27)
The FT DX 9000MP incorporates two large (3.4”/86 mm) high-precision analog meters, for the utmost accuracy in measuring transceiver
performance. Visibility is enhanced by the oversized meter scales, making the meters easy to read at all times.
Separated Clarifier Display (Pages 47, 97)
A clearly-separated display window within the main frequency display area contains receiver and/or transmitter frequency offset (“Clari-
fier”) data, for quick comprehension by the operator.
YAESU Custom-designed 32-Bit Floating Point IF DSP (Page 62)
The new IF DSP system, utilizing a TI TMS320C6711 device, is a high-speed 32-bit floating point circuit designed with a unique
objective: to do away with the “digital” sound of many DSP filtering systems, and emulate the “Analog Sound” so familiar and comfort-
able to HF DX and Contest operators. The result is a leading-edge receiver that has the “feel” of a traditional analog receiver, but with
the flexibility and superb filtering capability of a modern digital filtering system.
