1FT-891 Operating ManualIntroductionThe FT-891 is a rugged and innovative, multiband, multimode, mobile/portable transceiverfor Operation in the amateur radio HF/50 MHz bands. Providing coverage of the 160 - 6meter bands, the FT-891 includes operation in the SSB, CW, AM and FM modes, yieldingthe most comprehensive performance package available for mobile and field operation.Engineered for high performance, the FT-891 transceiver outputs 100 watts of power onthe 160 through 6 meter bands.The display includes bar-graph indications of: power output, ALC voltage, SWR, speechprocessor 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 thethree operating function keys ([A], [B], and [C]).Many advanced features that are included in the FT-891, have formerly only beenincorporated in large base station transceivers. These include:r Split-Frequency operation using the Dual VFOsr Digital Signal Processing (IF SHIFT, IF WIDTH, CONTOUR, IF NOTCH, NoiseReduction, Auto-Notch)r SSB Clarifier operation to permit offset adjustment of the receive frequency on SSBmode.r IF Noise Blankerr AGC Fast/Middle/Slow/Auto selectionr RF Gain and Squelch controlr IPO (Intercept Point Optimization) and a receiver front-end Attenuatorr AM Broadcast receptionr VOXr Built-in Electronic Keyer with Memories and a Beacon moder Adjustable CW Pitchr Spectrum Scoper 99 Memories and Band-limiting Memoriesr Alpha-Numeric Labeling of Memoriesr Automatic Power-Off (APO) and Time-Out Timer (TOT) functionsr Computer Interface capabilityWe urge you to read this manual and also the Advance Manual (available for downloadon the Yaesu website) in its entirety, to gain a full understanding of the amazing capabilityof the exciting new FT-891 Transceiver.
