Wide frequency coverage, outstanding receiver performance, and the convenience of remote-head operation* make the FT-857 the experts choice for high-performance mobile operation! Measuring 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 multimode transceiver! Its rugged case design is a masterpiece of ergonomic design, with oftenused switches and knobs conveniently positioned for ULTRA COMPACT DESIGN WIDE FREQUENCY COVERAGE RUGGED, HIGH-OUTPUT TRANSMITTER DESIGN Providing transmitter coverage of the HF, 50 MHz, 144 MHz, and 430 MHz Amateur bands, the FT-857 also includes receive coverage on 100kHzto56MHz,76to108MHz,118-164MHz, and 420-470 MHz. Enjoy the excitement of public safety monitoring, along with weather broadcasts, AM and FM broadcasts, aviation communications, as well as the action on the Hambands! Borrowing extensively from the FT-897 transmitter design, the FT-857's rugged power amplifier section utilizes Bipolar Transistor devices,providinglownoise,lowdistortion,and highreliability.OnHFand6meters,youget100 Watts of clean power output, while on 2 meters you get 50 Watts out, and 20 Watts on 70 cm. Reliability is assured thanks to the extensive cooling system, featuring a thermostatically-controlled 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-857s DSP Unit features a 24-bithigh-techD/Achipforsignalprocessing. 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,foratotalof512combinations.Andfor CW, you may choose bandwidths of 240 Hz, 120 Hz,orarazor-sharp60Hz. DSP AUTO-NOTCH FILTER : To reduce interferencecausedbyannoyingcarrierswithin 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 carrierspresent. 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 wide variety of noise environments, without introducing appreciable distortion on the desiredsignal.Operatorfatigueisreduced,and signal-to-noiseratioissignificantlyenhanced. DSP MICROPHONE EQUALIZER : To match the FT- 857's TX audio response to the waveform produced by your voice and the microphone in use,theDSPsystemincludesafour-positionMic Equalizer circuit. The result is increased "talk power" as extraneous frequencies are suppressed, allowing all available power to be concentratedintoyourvoice'spattern. Building on the acclaimed performance of the FT-1000D, Mark-VFT-1000MP, and FT-897, Yaesu's engineers have crafted the FT-857s front end for a very low noise floor, along with wide dynamic range. Utilizing an up-conversion architectureforHFwithafirstIFof68.33MHz, 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 strongsignal challenges of today's crowdedbands! On VHF and UHF the verylow-noise MOS FET preamplifier is followed by an active DBM mixer, yielding the low noise figure required for weak- HIGH-PERFORMANCE RECEIVER DESIGN 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 currentoperatingfrequency. IF Noise Blanker : Optimizedforuseinthemobile environment, the FT-857 includes a highlyeffective IF Noise Blanker specifically designed forsuppressionofignitionandotherpulse-type noises. The Noise Blankers threshold is adjustableviatheMenu. Intercept Point Optimization (IPO) : Forreceptionon thelowerHFbands,wherelowNoiseFigureis 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,ifdesired,allowingmanualgaincontrolfrom thefrontpanel. 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 receivers frequency, without changing the transmit frequency. For wider-split pileups, the "Split"modeallowsyoutouseVFO-AandVFO- Bseparately,too. RF Gain Control : For noise reduction and/or variation of the AGC system threshold, the Menu allows the front panels "Squelch" controltooperateasan"RFGain"control. VOX : For hands-free Voice operation, the VOX CW OPERATING FLEXIBILITY The FT-857 is without peer in its array of mostasked-forfeaturesfortheCWexpert! Built-In Electronic Keyer : The FT-857's built-in Electronic Keyer includes a weight control, as well as Menu capability to reverse the "Dot" and"Dash"contactsonyourconnector. CW Message Memory with Beacon Mode : For repetitive "CQ TEST" and contest exchange messages, the FT-857 includes a three-message memory capability. The "Beacon" mode may be used to send a repetitive message out continuously for up to four hours, ideal for 6meteruseduringDX-peditions. CW Pitch/Sidetone Control : The CW Pitch control allows the transmitted signal to be offset 400/500/600/700/800Hzfrom"zerobeat"withthe receive frequency. This adjustment simultaneously varies the center frequency of the RX passband (including the DSP BPF), as well as the CW Sidetone pitch. The Sidetone therefore servesasa"Spot"signalduringtuning. CW Trainer : A popular feature of the FT-857 is the CW Trainer, which will send five-character letters and/or numbers via the speaker, so you Foroperationonawidevarietyofdigitalmodes, including1200/9600bpsFMpacket,RTTY,SSTV, or PSK31, the rear-panel 6-pin mini-DIN connector provides easy to Data I/O lines, plus PTT and Ground. For PSK-31 and other AFSK modes, the injection sideband (USB/LSB) is selectable, along with BFO and Display Shift and EASY DATA-MODE SETUP 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 silkysmooth 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 Battery Voltage Meter TX Meter Selection Modulation Level, ALC, Power Output, or SWR.

Versatile Tone Control Selections :BothCTCSSand 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 requiringsplitCTCSS/DCSaccess,aconvenient "Split Tone" feature is also provided, along with the ability to encode (only) CTCSS or DCS, if desired. Automatic Repeater Shift : On the 144 MHz and 430 MHz bands, the FT-857 will automatically activate the repeater shift appropriate for the partofthebandinwhichyouareoperating. Smart Search : When visiting a new city, use the Smart Search system to scan the FM/AM Mode for activity. When busy channels are found, they will be automatically loaded into a special Smart Search memory bank, for easy recall.

Utilizing DC voltages fed from the FT-857, the ATAS-120 automatically adjustsitslengthlongeror shorter, with the FT-857 feeding a tiny amount of power for SWR detection by its internal directional coupler. When the best impedance match is found,tuningautomatically stops, and operation can begin. Specified for operation on the 7/14/21/28 MHz Amateurbands,theATAS- 120 contracts fully for use on the 50/144/430 MHz bands, providing a low SWR for local FM work (where 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 radiationontheVHF/UHFbands.
