FT-891 Operating Manual
Introduction
The FT-891 is a rugged and innovative, multiband, multimode, mobile/portable transceiver
for Operation in the amateur radio HF/50 MHz bands. Providing coverage of the 160 - 6
meter bands, the FT-891 includes operation in the SSB, CW, AM and FM modes, yielding
the most comprehensive performance package available for mobile and field operation.
Engineered for high performance, the FT-891 transceiver outputs 100 watts of power on
the 160 through 6 meter bands.
The display includes bar-graph indications of: power output, ALC voltage, SWR, speech
processor compression level, drain current of the final stage FET, and signal strength.
Also included are a number of operating status icons, as well as function displays for the
three operating function keys ([

Many advanced features that are included in the FT-891, have formerly only been
incorporated in large base station transceivers. These include:
r
Split-Frequency operation using the Dual VFOs
r
Digital Signal Processing (IF SHIFT, IF WIDTH, CONTOUR, IF NOTCH, Noise
Reduction, Auto-Notch)
r
SSB Clarifier operation to permit offset adjustment of the receive frequency on SSB
mode.
