GENERAL DESCRIPTION

Congratulations on the purchase of your Yaesu amateur transceiver! Whether this is your first rig, or if Yaesu equipment is already the backbone of your sta- tion, rest assured that your transceiver will provide many hours of operating pleasure for years to come.

The MARK-VFT-1000MPis an elite-class HF trans- ceiver providing exceptional performance both on trans- mit and receive. The MARK-VFT-1000MPis designed for the most competitive operating situations, whether you primarily operate in contest, DX, or digital-mode environments.

Built on the foundation of the popular FT-1000MP transceiver, the MARK-VFT-1000MPprovides up to 200 Watts of power output on SSB, CW, and FM (50 Watts AM carrier). Additionally, a Yaesu-exclusive “Class-A” SSB operating mode provides ultra-linear signal output, at a power output level of up to 75 Watts.

Also new on the MARK-VFT-1000MPis the IDBT (Interlocked Digital Bandwidth Tracking) System, which automatically aligns the bandwidth of the Enhanced Digital Signal Processing (EDSP) receiver passband to match the IF filter passband. This improves operat- ing efficiency by removing the extra step of making separate analog and DSP filter adjustments. This fea- ture can be enabled or disabled with the press of a button, for maximum flexibility.

And for exceptional protection from strong nearby incoming signals, the new, Yaesu-exclusive VRF (Vari- able RF Front-End Filter) serves as a high-performance Preselector-ideal for multi-operator contest environ- ments. This filter is manually tuned, allowing the op- erator to optimize sensitivity or signal rejection with the twist of a knob.

In addition to the contribution of the VRF Preselector, superb receiver performance is a result of direct lin- eage from the legendary FT-1000D and FT-1000MP. New technology Direct Digital Synthesizers (two 10-bit and three 8-bit) are used in the local oscillator (all driven by a single TCXO master oscillator), resulting in ex- tremely fine tuning resolution with thirteen selectable tuning steps down to 0.625 Hz. You may select either “Flat” or “Tuned” front end RF amplification (using four FETs in a double push-pull, constant-gain stage), IPO (Intercept Point Optimization) utilizing direct feed to the first mixer, and/or three levels of RF attenuation in 6- dB steps. The “Tuned” RF Preamplifier provides high gain and low noise figure on the higher frequency bands, with lower gain and greater selectivity on the low bands, where strong-signal performance is criti- cally important.

To battle QRM, the MARK-VFT-1000MPcomes equipped with a formidable defense. Fine tailoring of the IF passband is made possible with individually-se- lected, cascaded 2nd- and 3rd-IF crystal filter banks. World-renowned Collins® mechanical 500-Hz CW fil- ters are available as options for the Sub Receiver 2nd IF, and main receiver 3rd IF strip. An IF notch filter and concentric IF Shift and Width controls are also pro- vided. The IF Width circuit allows continuously narrow- ing receiver passband by selectively moving either the upper or lower filter skirt just as much as needed to reduce QRM while still preserving the maximum us- able bandwidth. This extensive analog IF filtering pro- tects the EDSP circuits that follow it, ensuring un- matched performance during crowded band conditions.
