FT-857 Operating Manual
Introduction
The FT-857 is a rugged, innovative multiband, multimode portable transceiver for the amateur radio MF/HF/VHF/UHF
bands. Providing coverage of the 160-10 meter bands plus the 6 m, 2 m, and 70 cm bands, the FT-857 includes operation
on the SSB, CW, AM, FM, and Digital modes, yielding the most comprehensive performance package available for field
operation.
Designed for use from (1) an external DC power source, (2) internal battery (requires optional FNB-78 Ni-MH battery
pack), the FT-857 provides 100 watts of power output from a 13.8-Volt external power supply or AC operation. When
using the optional FNB-78 Ni-MH Battery Pack, the FT-857 automatically switches to 20 Watts (430 MHz:10W) of
output power.
The multi-function Liquid-Crystal Display includes attractive backlighting, which may be disabled for battery
conservation. The display includes bar-graph indication of power output, ALC voltage, SWR, and modulation level. Also
include are a number of operating status icons, as well as the function displays for the three operating function keys (A, B,
and C).
Among the advanced features of the FT-857 are many incorporated only in large base-station transceivers. These include
Dual VFOs; Split-Frequency operation; Digital Signal Processing (Bandpass Filtering, Noise Reduction, Notch, and
Microphone Equalizer); IF Shift; Clarifier (“R.I.T.”); IF Noise Blanker; AGC Fast/Slow/Auto/Off selection; RF Gain and
Squelch control; IPO (Intercept Point Optimization) and a receiver front-end Attenuator; AM Aircraft reception; AM and
FM Broadcast reception; U.S. Weather Band reception; VOX; Built-in Electronic Keyer; Adjustable CW Pitch;
Automatic FM Repeater Shift (ARS); Built-in CTCSS Encoder/Decoders; ARTS™ (Auto-Range Transponder System);
Smart Search™ Automatic Memory Loading System; Spectrum Scope; 200 Memories plus Home Channels and Band-
limiting Memories; Alpha-Numeric Labeling of Memories; Automatic Power-Off (APO) and Time-Out Timer (TOT)
functions; Computer Interface capability; and Cloning capability.
We urge you to read this manual in its entirety, so as to gain a full understanding of the amazing capability of the exciting
new FT-857 Transceiver.
