ULTRA COMPACT DESIGN

Masuring just 6.1″ x 2″ x 9.2″ (155 x 52 x 233 mm), the FT-857 is the world’s smallest full-power HF/ VHF/ UHF m u l t i m o d e transceiver! Its rugged case design is a masterpiece of ergonomic design, with often- used switches and knobs conveniently positioned for.

RUGGED, HIGH-OUTPUT TRANSMITTER DESIGN

Borrow ing extensively from the FT-897 transmitter design, the FT-857’s rugged power amplifier section utilizes Bipolar Transistor devices, providing low noise, low distortion, and high reliability. On HF and 6 meters, you get 100 Watts of clean power output, while on 2 meters you get 50 Watts out, and 20 Watts on 70 cm. Reliability is assured

TX POWER OUTPUT (SSB,CW,FM)

HIGH-PERFORMANCE RECEIVER DESIGN

Building on the acclaimed performance of the FT-1000D, M ark-VFT-1000M P, and FT-897, Yaesu’s engineers have crafted the FT-857’s front end for a very low noise floor, along with w ide dynamic range. Utilizing an up-conversion architecture for HF with a first IF of 68.33 M Hz, the FT-857 features a double-conversion superheterodyne system (single conversion on WFM ), with the 2nd IF at 455 kHz. Extensive bandpass filtering in the front end, along with careful device selection and gain distribution, yield a receiver system ready for the strong-signal challenges of today’s crow ded bands! On VHF and UHF the very- low -noise M OS FET preamplifier is followed by

an active DBM mixer, yielding the low noise figure required for weak.

WIDE FREQUENCY COVERAGE

Providing transmitter coverage of the HF, 50 M Hz, 144 M Hz, and 430 M Hz Amateur bands, the FT-857 also includes receive coverage on 100 kHz to 56 M Hz, 76 to 108 M Hz, 118-164 M Hz, and 420-470 M Hz. Enjoy the excitement of public safety monitoring, along with weather broadcasts, AM and FM broadcasts, aviation communications, as well as the action on the Ham bands!

ENHANCED TRANSCEIVER PERFORMANCE THROUGH DIGITAL SIGNAL PROCESSING (Optional DSP-2 Unit Required)
For superior interference rejection and transmitter “talk power,” the FT-857’s DSP circuitry enhances both sides of the c o m m u n i c a t i o n s circuit. The FT-857’s DSP Unit features a 24-bit high-tech D/A chip for signal processing.

• DSP BANDPASS FILTER : Separate DSP Bandpass Filters for Voice and CW augment the analog filters for enhanced interference rejection. For Voice modes, you get 16 High-Pass Filter cutoff frequency selections, and 32 Low -Pass Filter selections, for a total of 512 combinations. And for CW, you may choose bandwidths of 240 Hz, 120 Hz, or a razor-sharp 60 Hz.
• DSP AUTO-NOTCH FILTER : To reduce  interference caused by annoying carriers within the audio passband, the DSP Auto-Notch provides a significant reduction in the interference level. If multiple carriers are present, the DSP will detect and notch all the carriers present.
• DSP NOISE REDUCTION : The very effective Noise
  Reduction filter of the FT-857 utilizes as many as 16 noise-reduction algorithms, for use in a w ide variety of noise environments, w ithout introducing appreciable distortion on the desired signal. Operator fatigue is reduced, and signal-to-noise ratio is significantly enhanced.

HIGH-PERFORMANCE PLL DESIGN

The quiet, fast-acting local oscillator system of  the FT-857 borrows extensively from the FT-847 and FT-897, using a Direct Digital Synthesizer (DDS) to achieve fast lock times and silky-smooth tuning in steps as fine as 10 Hz. The excellent carrier-to-noise ratio helps preserve spurious-free dynamic range in a crowded band, and the smooth tuning leaves you with.

UNMATCHED EASE OF ACCESS TO FEATURES

Despite its compact size, the FT-857 is without peer in ease of access to the features and functions you need the most!

BIG-RADIO TUNING DIAL AND OUTSTANDING ERGONOM ICS : Ease of operation of the FT-857 is enhanced by the large diameter 1.7” (Ø43 mm) Main Tuning Dial (10 Hz steps minimum), similar in size to the tuning knob of many base station rigs. What’s more, the SELECT knob allow s “channelized” tuning in minimum steps of 1 kHz on SSB/CW, or 5 kHz on FM , for quick and easy tuning around the band. All important
keys are strategically placed around the front panel, for quick access.

EASY-TO-USE “SCROLLING FRONT PANEL” KEYS :
The compactness of the FT-857 is made possible by the easy-to-use “multi- function” keys, which allow adjustment of a number of transceiver operating functions during operation. Pressing the [FUNC] key allows selection of the operating function row, using the Selector knob, and you may then press the [C] key, as needed, to change the

ADVANCED FEATURES FOR ACTIVE DXers

• IF Shift : Use the IF SHIFT feature to vary the center frequency of the IF passband, so as to eliminate interference above or below the current operating frequency.

• IF Noise Blanker : Optimized for use in the mobile environment, the FT-857 includes a highly-effective IF Noise Blanker specifically designed for suppression of ignition and other pulse-type noises. The Noise Blanker’s threshold is adjustable via the Menu.

• Intercept Point Optimization (IPO) : For reception on the lower HF bands, where low Noise Figure is not required, the IPO feature causes the RF preamplifier to be bypassed, allowing direct signal input to the first mixer. An input attenuator is also provided, for very noisy conditions.

• Adjustable AGC : The Automatic Gain Control (AGC) circuitry of the FT-857’s receiver may be adjusted, by the operator, for Slow or Fast recovery times. A convenient “Auto” feature programs “Fast” AGC for CW , and “Slow ” for voice modes. And the AGC may also be turned off, if desired, allowing manual gain control from the front panel.

• Clarifier (R.I.T.) : For split-frequency pile-ups or to follow drifting signals, the Clarifier control provides up to ± 9.99 kHz of adjustment of the receiver’s frequency, w ithout changing the transmit frequency. For wider–split pileups, the “Split” mode allows you to use VFO-A and VFO-
  B separately, too.

• RF Gain Control : For noise reduction and/or variation of the AGC system threshold, the M enu allow s the front panel’s “Squelch” control to operate as an “RF Gain” control.

• VOX : For hands-free Voice operation, the VOX

ADVANCED CONVENIENCE FEATURES FOR VHF/UHF OPERATION

The FT-857 is a VHF/UHF operator’s dream come true!

• Versatile Tone Control Selections : Both CTCSS and DCS Encoder/Decoders are built in! For easy access to repeaters, a 50-tone CTCSS system works along with a 104-code Digital Code Squelch (DCS) in the FT-857. For applications requiring split CTCSS/DCS access, a convenient “Split Tone” feature is also provided, along with the ability to encode (only) CTCSS or DCS, if desired.

• Automatic Repeater Shift : On the 144 M Hz and 430 M Hz bands, the FT-857 will automatically activate the repeater shift appropriate for the part of the band in which you are operating.

• Smart Search™ : When visiting a new city, use the Smart Search system to scan the FM /AM M ode for activity. W hen busy channels are found, they will be automatically loaded into a special Smart Search™ memory bank, for easy recall.

• Spectrum Scope : If you have to be away from
  your radio for a few minutes, turn on the Spectrum Scope to keep watch on band activity. The Spectrum Scope will create a bar-graph display of activity on channels above and below your current operating frequency.

• ARTS™(Auto-Range Transponder System) : During Search-and-Rescue operations, the ARTS™

ACTIVE-TUNING ANTENNA SYSTEM (ATAS-120 Option)

Yaesu’s patented ATAS-120 Active-Tuning Antenna System provides a compact, yet efficient, automatically- adjusting antenna for mobile, portable, or apartment-balcony use! Utilizing DC voltages fed from the FT-857, the ATAS-120 automatically adjusts its length longer or shorter, with the FT-857 feeding a tiny amount of power for SWR detection  by its internal directional coupler. W hen the best impedance match is found, tuning automatically stops, and operation can begin. Specified for operation on the 7/14/21/28 M Hz Amateur bands, the ATAS-120 contracts fully for use

on the 50/144/430 M Hz bands, providing a low SW R for local FM work (w here vertical polarization is predominant). And if you’re an apartment dweller, use the optional ATBK-100 Antenna Base Kit, which provides an outstanding counterpoise to ensure low-angle

VERSATILE MEMORY SYSTEM!

The FT-857 provides up to 200 “Main” memory channels, each of which may be named with an Alpha-Numeric label of up to eight characters. These 200 Memories may be separated into as many as 10 Memory Groups of 20 Memories each. For added convenience, you also get a “Quick Memory” and a “Home Channel” on each band, plus Five pairs of band-limit memories, to let you restrict operation to a sub-band, if you
