The FT-857D, the
world's smallest HF/VHF/UHF mobile transceiver, provides base station-type
performance from an ultra-compact package that's ideal for mobile or external
battery portable work. Wide frequency coverage, outstandig receiver performance,
and the convenience of optional remote-head operation make the FT-857D the
expert's choice for high-performance mobile operation!
The new FT-857D version includes coverage of the
U.S. 60-meter (5 MHz) band, plus the previously-optional DSP circuitry, at no
additional cost!

Ultra
Compact Design
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 often-used switches and knobs conveniently
positioned for easy access. High-Performance Receiver Design
Building
on the acclaimed performance of the FT-1000D, Mark-V FT-1000MP, and FT-897,
Yaesu?s engineers have crafted the FT-857?s front end for a very low noise
floor, along with wide dynamic range. Utilizing an up-conversion architecture
for HF with a first IF of 68.33 MHz, the FT-857 features a double-conversion
superheterodyne system (triple conversion on FM), with the 2nd IF at 10.7 MHz.
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 crowded bands! Wide
Frequency Coverage
Providing
transmitter coverage of the HF, 50 MHz, 144 MHz, and 430 MHz Amateur bands, the
FT-857 also includes receive coverage on 100 kHz to 56 MHz, 76 to 108 MHz,
118-164 MHz, 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 Ham bands! 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 ten pairs of band-limit memories, to let you restrict operation to a
sub-band, if you like. Digital
Signal Processing (option)
For
superior interference rejection and transmitter ?talk power,? the FT-857?s
optional DSP circuitry enhances both sides of the communications circuit. The
FT-857?s DSP Unit features a 24-bit high-tech D/A chip for signal processing.
Included are Bandpass Filter, Auto-Notch, and Noise Reduction filters, along
with a Microphone Equalizer. Big Radio
Tuning Dial and Outstanding Ergonomics
Ease of
operation of the FT-857 is enhanced by the large-diameter (1.7?) Main Tuning
Dial, similar in size to the tuning knob of many base station rigs. Selectable
tuning steps of 2 kHz/4 kHz per revolution allow easy navigation around your
favorite bands, while important keys and switches are strategically placed
around the front panel for quick access.
