The FT-857 / FT-857D
is the world's
smallest full-power HF/VHF/UHF multimode transceiver, offering
exceptional performance, ergonomics, and operating convenience for the
active mobile operator. Providing 100 Watts of power on HF/6 meters,
50 Watts on 2 meters, and 20 Watts on 70 cm, the FT-857 is also ideal
for vacation, DX-pedition, or home use when space is at a premium.
Borrowing its receiver technology from the renowned FT-897 and
Mark-VFT-1000MP, the FT-857 features wide dynamic range, a
high-performance noise blanker, and outstanding audio.
The wide array of convenience features on the FT-857 includes a
32-color display; optional Digital Signal Processing; built-in keyer
with three memories and beacon mode; 200 memories with Alpha-Numeric
labels; U.S. Weather Band reception; AM Aircraft reception; detachable
front panel (optional YSK-857 required); and much, much more.
The FT-857D has a build
in DSP2 Unit. This is the main difference between FT-857
and FT-857D
