-----
The FT-891 is Yaesus most compact 100W allmode transceiver for shortwave. Due to the small size the radio is perfectly suited for installation in a car,
but can be used of course also at home. The front panel is detachable (requires option YSK-891).
The FT-891 supports operation on all shortwave bands from 160 to 10m as well as the 6m band (50 MHz). The transmit power is 100W in SSB/CW
and 25W in AM. The supported operating modes are SSB (USB/LSB), CW, AM and FM. The receiver is designed as a triple conversion super
heterodyne (FM: double super het) and offers very good results concerning sensitivity and large signal handling. A 3 kHz roofing filter is installed by
default, this helps in very good near signal selectivity. A TCXO is also installed by default and offers a frequency stability of ±0.5ppm.
On the IF level the FT-891 is equipped with a powerful 32 bit signal processor (DSP). With this DSP system you do not need to buy costly crystal
filters anymore, the IF filter characteristics can be adjusted individually for each mode. The same DSP also supports an effective noise reduction
and notch filter functions (automatic and manual). An inheritance from the large desktop transceivers by Yaesu is the 'Contour' and 'Audio Peak
Filter' (APF) which both greatly help to raise the intelligibility of a signal in most cases.
The ease of use of the transceiver is supported by a large and clear LC display. A large tuning button and a multi function button are used to
quickly navigate the menu system for all settings. Three buttons on the front panel can be freely programmed to the users requirements.
A multi colour indicator to the side of the display shows the currect state of the transceiver (Squelch status, transmitter status).
The FT-891 provides a USB interface which can be used as a CAT interface for remote control. The usual digital modes are done via the
"RTTY/DATA" socket [1]. Besides the USB and Data socket the FT-891 also offers the usual Yaesu Tuner/Linear socket, so you can continue
to use existing options with this transceiver. Other connections are available for Remote/ALC, a morse key and an external speaker.
As with many other Yaesu mobile transceivers, the FT-891 also supports the use of the ATAS-120A mobile HF antenna. With this function an
automated system for HF communication can be installed very easily in a car or on a boat. The antenna connection is a PL socket, optionally
the desktop tuner FC-50 is available for easy tuning of other antennas. The FC-40 tuner fr end fed wires can be used as well. Included in the
shipment is a hand microphone MH-31A8J. Optionally the external keypad FH-2 can be connected.
Included in supply
FT-891 HF mobile transceiver 100W
Hand held microphone MH-31A8J
MMB-82 mounting bracket
Microphone holder
DC power cable with fuses
Spare fuses, small parts
Uncompromising Receiver Circuit Design Ensures Excellent Performance
• Triple conversion with a 1st IF frequency of 69.450 MHz (SSB/CW/AM
• 3 kHz roofing filter equipped as standard feature
• TCXO provides ±0.5 ppm High frequency stability (-10°C to +50°C)
Stable 100 Watt Output
The FT-891 provides stable 100 Watts (25W AM) of high power output. High reliability is assured by the transmitters careful circuit design with efficient thermostatically-controlled Dual internal fans and the die cast heat transferring chassis.
32-Bit IF DSP Provides effective and optimized QRM rejection
The 32 bit high speed floating Point DSP (max 3000 MIPS) provides effective cancellation/reduction (DNR) of the random noise that is frequently frustrating while on the HF bands. The highly optimized AUTO NOTCH (DNF) automatically eliminates dominant beat tones, and the CONTOUR, and the APF, are very effective receiver noise reduction tools during HF band operations.
USB Connection
A native USB connection supports PC connectivity with a single cable, allowing for full rig control via a virtual serial port connection (VCP).
Features for Ease of Operation
• Large diameter Main Tuning Dial (1.6” / 41mm) with Torque adjustment
• Pop-up Menu for quick and easy navigation
• Multi-function Knob
• Large Transmit/Receive indicator
• Three programmable Front Panel Function Keys
Support for ATAS (Active Tuning Antenna System)
The FT-891 fully supports the ATAS-25 and ATAS-120A Active Tuning Antenna System (optional) allowing for plug and play field and mobile operation.
Ultra compact design
Measuring 6.1” x 2.0” x 8.6” (155 x 52 x 218 mm), The FT-891 is an innovative Multi-band, Multi-mode Mobile/Portable transceiver with an Ultra Compact and rugged case design.
Optional FC-50 Antenna Tuner Unit
The FC-50 is a microprocessor-controlled antenna tuner that is designed specifically for the FT-891. The FC-50 can be easily coupled with the FT-891 and includes all necessary interconnect cables for operation right out of the box.
