Extensive Receiver DSP Filtering!

The power of IF Digital Signal Processing (DSP) is yours to enjoy with the FT-2000/D. Variable IF Width and IF Shift allow precise interference rejection, and the receiver DSP also includes an Auto-Notch, Manual Notch, Digital Noise Reduction, and a continuously-variable passband Contour control. 

The WIDTH control has a mode-determined adjustment range of 200 Hz – 4 kHz for SSB, and 25 Hz to 2.4 kHz on CW, and a mode-optimized “Narrow” key provides one-touch narrowing of the bandwidth to a user-determined preset value.

User-Adjustable Variable TX Bandwidth!

With the FT-2000/D, you have tremendous control over the fidelity and/or “talk power” of your SSB signal, thanks to the variable SSB bandwidth capability in the Menu. The default bandwidth is 2.4 kHz (300 – 2400 Hz @ -6 dB), but you also have selections of 50 – 3000 Hz, 100 – 2900 Hz, 200 – 2800 Hz, and 400 – 2600 Hz, allowing you to select the bandwidth best suiting your operating needs.

3-Band Parametric Microphone Equalizer!

The power of DSP also provides tremendous benefits for transmission, as well as reception. The Three-Band Parametric Microphone Equalizer allows unmatched capability to tailor your speech characteristics: in each of the three bands, you may adjust the center frequency of the equalization, the frequency spread over which the equalization is applied, and the amplitude (peaking or nulling) within that equalization range. The result is sparkling, clear audio that will be the envy of everyone else on the band!

Outstanding Strong-Signal-Handling Capabilities Derived from the FTDX9000!

Following in the renowned path of the FTDX9000, the FT-2000/D is crafted with a comprehensive design view that accounts for all aspects of the strong signal environment, and especially with optimization of weak-signal in a multiple-strong-signal environment. 

The receiver of the FT-2000/D is a triple-conversion type, utilizing great care in the gain distribution through all IF stages. The first mixer is a GaAs FET Doubly-Balanced Mixer type, fed by a four-VCO PLL synthesizer (30 kHz – 10.5 MHz, 10.5 MHz – 24 MHz, 24 MHz – 39 MHz, and 39 MHz – 56 MHz). The resulting first IF is at 69.450 MHz, utilizing an up-conversion technique that yields excellent image rejection.

FTDX9000-Lineage Triple Roofing Filter System for Crowded Bands (Main Band VFO)

The first IF of the FT-2000/D features three roofing filters, I bandwidths of 15 kHz, 6 kHz, and 3 kHz, optimized by mode for best performance on today’s crowded bands. Especially useful during busy contest weekends, the Roofing Filters are positioned right after the first mixer, improving IP3 (3rd-Order Intercept Point) performance for all stages that follow.

The Ultimate Low-Band DXer RF Preselection Filter: YAESU’s Exclusive ?-Tuning!

On the lower Amateur bands, the signal voltages impinging on a receiver can create noise and Intermodulation effects that can cover up weak signals you’re trying to pull through. So YAESU’s engineers developed the ? (Mu) Tuning system for the FTDX9000, and it’s now available as an option for the FT-2000/D. Three modules are available (MTU-160, MTU-80/40, MTU-30/20), and these modules may be connected externally with no internal modification required! When ?-Tuning is engaged, the standard VRF (Variable RF Preselector) system is bypassed, but the fixed Bandpass Filters are still in the received signal path. 

The ?-Tuning filters utilize a stack of large 1.1” (28 mm) Ni-Zn Ferrite cores, driven through a silver-plated coil assembly by a precision stepper motor. The resulting high Q (typically over 300) provides a very steep resonance peak near your operating frequency. The peak may be adjusted away from your frequency, for even greater protection from a specific station, and a graphical depiction of the ?-Tune filter alignment appears on the front panel of the transceiver.
