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
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-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.
