WIDE FREQUENCY COVERAGE
RUGGED, HIGH-OUTPUT TRANSMITTER DESIGN
Providing transmitter coverage of the HF, 50

public safety monitoring, along with weather
broadcasts, AM and FM broadcasts, aviation
communications, as well as the action on the

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
communications
circuit. The FT-
857’s
DSP Unit features a
24-bithigh-techD/Achip forsignalprocessing.

DSP BANDPASS FILTER : Separate DSP
Bandpass
FiltersforVoiceand CW augment the analog
filters

modes, you get 16 High-Pass Filter cutoff
frequency
selections, and 32 Low-Pass Filter
selections,fora
totalof512combinations.Andfor
CW,youmaychoose

•
DSP AUTO-NOTCH FILTER : To reduce
interferencecausedbyannoyingcarrierswithin

provides a significant reduction in the
interference level. If multiple carriers are
present, theDSPwilldetectandnotchallthe

DSP NOISE REDUCTION : The very effective
Noise
Reductionfilter of theFT-857 utilizes asmany
as 16 noise-
reduction algorithms, for use in a
wide variety
of noise environments, without
introducing appreciable distortion on the
desiredsignal.Operatorfatigueisreduced,and

•
DSP MICROPHONE EQUALIZER : To match the FT-
857's
TX audio response to the waveform
produced by your voice and the microphone in
use,theDSPsystem includesafour-positionMic
Equalizer circuit. The result is increased "talk
power" as extraneous frequencies are
suppressed,allowingallavailable powertobe

Buildingon the acclaimed performanceof the
FT-1000D,Mark-VFT-1000MP,and FT-897,Yaesu's
engineershavecraftedtheFT-857’sfrontend
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

ADVANCED FEATURES FOR ACTIVE DXers
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
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.
Specifiedforoperation on
the 7/14/21/28 MHz
Amateurbands,theATAS-
120contractsfullyforuse
onthe50/144/430MHz 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
