Building on the tremendous success of the Yaesu FT-1000D (FT 1000D, FT1000D) and Yaesu FT-1000MP (FT1000MP, FT 1000MP) Premier Class HF Transceivers, the MARK-V brings five exciting new developments in amateur radio technology.

Conservatively Designed 200W MOSFET Final Amplifier
The MARK-V utilizes a pair of Philips BLF147 Power MOSFETs in a 30-Volt, push-pull configuration. These 300-Watt (150-Watt x 2) transistors are run well below their maximum ratings, ensuring high reliability and excellent signal purity. The time-proven Low-Pass Filter network, adopted from the Yaesu FT-1000D (FT1000D, FT 1000D) effectively suppresses harmonic energy while efficiently delivering at least 200 Watts to the antenna jack.
  High-Speed Automatic Antenna Tuner 
The basic circuitry from the widely-acclaimed Automatic Antenna Tuner of the Yaesu FT-1000MP (FT1000MP, FT 1000MP) has been beefed up for operation at the 200-Watt level for incorporation in the MARK-V. Constructed on a glass-epoxy circuit board for maximum efficiency, the Automatic Antenna Tuner's dedicated microprocessor utilizes a complex analysis algorithm which permits lightning quick matching of impedance mismatches. The result: more power delivered to the antenna, and less time wasted in tuning! 

Revolutionary Heat Sink Design for Contest and DX-pedition Environments 
Providing 200 Watts of momentary output from a compact transceiver enclosure is easy; creating an HF powerhouse that will pump out full power for days at a time is tough! Yaesu* s engineers, seeking to fulfill the needs of both contest and DX-pedition operators, have crafted an all-new, highly-efficient "T-configuration" heat sink for the MARK-V, providing double the heat- dissipating surface area and 2.5 times the cooling capacity of the heat sink on the Yaesu FT-1000D (FT1000D, FT 1000D)! When the going gets tough, the thermostatically-controlled cross-flow fan engages at 40 °C dueling the heat across the dissipating fins and away from the case. This revolutionary new heat sink design ensures that the MARK-V will not let you down, even under the aggressive operating circumstances of an expedition to a rare tropical island!

Uniquely-Pure Signal Quality, Only from Yaesu! 
The MARK-V is the first commercially-designed Amateur transceiver to provide Class-A operation for its power amplifier. When engaged by the front panel's [CLASS A] switch, the PA bias is changed dramatically, and the MARK-V then puts out a 75-Watt signal envelope of astounding purity. During Class-A operation, 3rd-order Intermodulation Distortion (IMD) drops from a typical value of-31 dB to -50 dB or better, and 5th- and higher-order IMD (the kind which contributes to "splatter" reports) will drop to the -80 dB range! No Amateur transceiver has ever approached this degree of linearity in its power amplifier circuitry. And while the MARK-V* s Class-A feature does not directly affect your linearamplifier's performance, the extremely clean drive to your linear will result in dramatically cleaner overall signal reproduction. Be ready for other stations to say, "Wow! Your rig sounds great!"
Interlocked Digital Bandwidth Alignment Technique 
The MARK-V introduces a unique and formidable interference-fighting system with the development of IDBT, whereby the bandwidth of the Digital Signal Processing filter is automatically locked to be the same as the net bandwidth of the analogue IF filters. Engaging the IDBT, the operator experiences a sudden sharpening of the shape factor of the receiver's filter system. The analogue IF, which utilizes cascaded crystal and/or mechanical filters, includes both IF WIDTH and IF SHIFT controls, which allow modification of the IF passband width and centre frequency. With IDBT, the DSP filter is automatically re-programmed so as to match the custom bandwidth you just set, and the DSP filter then contributes a filtering slope which resembles a sheer cliff! The results? The incredible selectivity of an all-DSP system with the protection of the DSP afforded by the extensive IF analog filtering. What's more, the potential for AGC "pumping" caused by different analogue and digital bandwidths is eliminated; thus, the need for separate analog and DSP AGC systems is also gone, eliminating the very real danger of annoying cross-AGC artifacts which can seriously degrade receiver performance. New to the 455 kHz analogue IF is a IO-Pole Collins ® Mechanical SSB Filter, providing outstanding voice signal reproduction along with enhanced skirt selectivity compared to the Yaesu FT-1000MP (FT1000MP, FT 1000MP) 's 8-pole filter. The IDBT function is controlled by an allocation of up to 60 kbytes of ROM in the Main CPU, while the DSP performance utilizes I Mbyte of EEPROM! This perfect blending of the analogue and digital worlds brings you, today* s Premier-Class operator, the most crunch-proof receiver filtering ever!

VRF Preselector Filtering Protects Receiver Front End (160M - 20M)
Extending the protection afforded the sensitive front-end components of the receiver, Yaesu* s engineers have developed the VRF module: a High-Q input "Preselector" filter ahead of all active devices in the front end, including the main bandpass filters! Particularly in multi-operator contest or DX-pedition environments, where large low-band antennas may be in close proximity, a receiver operating (for example) on 20 meters can suffer intermodulation interference from on-site 40- and 80-meter signals, compounded by extremely strong 7 MHz broadcast signals. The VRF circuit provides narrow-band selectivity which prevents this unwanted signal voltage from hitting the input side of the bandpass filter switching diodes, where 2nd-order IMD is most often created in an HF receiver. Tuning of the VRF is incredibly simple: just turn the VRF/MEM CH knob, and peak the background noise or signal strength! The VRF is stoutly designed, with large (10 mm x 10 mm) coils yielding high Q, and precision tuning capacitors ensuring that performance does not degrade over time. A total of 31 tuning memories per band allow very quick QSY, and the use of high-quality, shielded relays for VRF selection ensures that nothing in the VRF can itself contribute IMD.

Receiver Front End Highlights
The MARK-V adopts the low-noise front end design of the Yaesu FT-1000MP (FT1000MP, FT 1000MP). Two low-noise Junction FET preamplifiers are provided, one in a "tuned" configuration with optimized gain and noise figure independently for the high and low bands, with the other "flat" preamp providing a wide, uniform-gain response. The first mixer utilizes a quad of SST-310 Junction FETs in a doubly-balanced circuit, resulting in wide dynamic range. Eleven and pass filter networks provide input protection for the front end, working in concert with the VRF to provide the best-ever 2nd-order IMD prevention in an Amateur transceiver. 


Quick Access to VRF and IDBT via Shuttle Jog Tuning Ring 
The immensely-popular Shuttle Jog tuning ring, which is concentric with the Main Tuning Knob, has a new look in the MARK-V: it now includes the activation switches for the VRF (left side) and IDBT (right side) features, so the operator does not have to move his hand position to activate these important circuits during contest or pile-up situations! Superb Ergonomics Across the Front Panel Both the Main and Sub VFO Tuning Knobs are larger, allowing silky-smooth tuning even if you have large fingers! The right side of the front panel contains the adjustment controls for the VRF, IDBT, NOTCH, and CLARIFIER, conveniently grouped so you can get at them quickly. For contest or DX-pedition use, you cannot afford to lose even milliseconds in search of a frequently-used control.And the mosl popular EDSP functions from the Yaesu FT-1000MP (FT1000MP, FT 1000MP) are now much easier to use! The CW Audio Peaking Filter (with bandwidths of 60, 120, and 240 Hz) and the four-position EDSP Noise Reduction (NR) feature are conveniently located just to the left of the Main Tuning Dial, for quick, convenient push-button access. Right next to the APF and NR controls are the three EDSP response Contour selections, which enhance signal-to-noise ratio by matching the DSP frequency response to the unique shape of the incoming signal envelope.
