FT-891 HF/50 MHz TRANSCEIVER
The FT-891 is a rugged, innovative multiband, multimode mobile/portable transceiver for the amateur radio MF/HF/50 MHz bands. Providing coverage of the 160 – 6 meter bands, the FT-891 includes operation on 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 provides 100 watts power output on the 160 through 6 meter bands.
The multi-function Liquid-Crystal Display includes attractive backlighting. The display includes bar-graph indication of power output, ALC voltage, SWR, modulation level, and/or signal strength. Also included 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-891 are many incorporated only in large bases-tation transceivers. These include Dual VFOs; Split-Frequency operation; Digital Signal Processing (Bandpass Filtering, Noise Reduction, Auto-Notch, and Microphone Equalizer);
IF Shift; Clarifier (“R.I.T.”); IF Noise Blanker; AGC Fast/Middle/Slow/Auto selection; RF Gain and Squelch control; IPO (Intercept Point Optimization) and a receiver front-end Attenuator; AM Broadcast reception; VOX; Built-in Electronic Keyer with Memories and a Beacon mode; Adjustable CW Pitch; Automatic FM Repeater Shift (ARS); Built-in CTCSS Encoder/Decoders;
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.
Uncompromising Receiver Circuit Design Esnures 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.
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

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.
Front Panel Controls & Switches
- RF/SQL knob
This (outer) SQL/RF knob adjusts the gain of the receiver’s RF and IF stages. Using Menu Mode “No 05-05 [RF/SQL VR]”, this control may be changed to function as a Squelch control.
2. MULTI knob
This detented rotary switch is used for function selection for the [A], [B], [C] keys of the transceiver.
3. AF Knob
The (inner) VOL knob adjusts the receiver audio volume level presented to the internal or external speaker. Clockwise rotation increases the volume level.
4. MODE key
Pressing either of this key momentarily will change the operating mode. The selections available are:
⇒ LSB ⇒ CWL (CW LSB) ⇒ R-L (RTTY LSB) ⇒ P-L (PACKET LSB) ⇒ AM ⇒ LSB ⇒
Repeated presses of this key steps through the available selections. Pressing and holding this key will toggle to the alternate mode. For example, In the LSB or USB modes, a long press of this key toggles between “LSB” and “USB” mode.
5. RC/ST key
Press and hold this key for more than one second to write the frequency and data currently set for VFO-A onto the quick memory bank (QMB)
- 5 channels are available for QMB memories. Press the button briefly to recall the data written onto the quick memory banks (QMB) one by one.
6. [V>M] key
Pressing and holding this key for one second (until the double beep) copies the current operating data into the currently selected memory channel, over-writing any previous data stored there.
Press this button briefly to display the memory check function screen, where the data saved in a memory channel may be reviewed.
Press this button again, to close the memory list screen.
7. [V/M] key
This key toggles frequency control between VFO and the memory system. O Pressing this key alternately recalls the VFO frequency data and the frequency data saved in a memory channel by turns.
8. [A/B] key
Pressing this button momentarily, exchanges the frequency and memory channel data, of VFO-A and VFO-B.
9. [DOWN]/[UP] key
Pressing either of these keys momentarily will cause the frequency to be moved up or down by one frequency band. The selections available are:
….. 1.0 MHz ⇔ 1.8 MHz ⇔ 3.5 MHz ⇔ 5.0 MHz ⇔ 7.0 MHz ⇔ 10 MHz ⇔ 14 MHz ⇔ 15 MHz ⇔ 18 MHz ⇔ 21 MHz ⇔ 24 MHz ⇔ 28 MHz ⇔ 50 MHz ⇔ 1.0 MHz…..
10. [Power/Lock] key
Press and hold in the Power key for one second to turn to the transceiver on or off. Briefly pressing the key while the transceiver is turned ON engages or releases the key lock.
11. TX/BUSY Indicator
This indicator glows green when the squelch opens, and turns red during transmit.

Connect a computer with a commercially available USB cable to control the transceiver remotely from the computer using the CAT command. Inputting/Outputting audio signals and transmission control can also be done from the computer.
5. ACC Jack
This 3.5-mm 3-pin jack accepts external ALC (Automatic Level Control) voltage from a linear amplifier on the tip connection, and accepts a “Transmit Request” command on the ring connection. The main shaft is the ground return.
The “TX Request” connection, when shorted to ground, puts the FT-891 into the transmit mode, and sends out a steady CW carrier, for linear amplifier or manual antenna tuner adjustment.
6. KEY Jack
This 3.5-mm, 3-pin jack is used for connection to a CW keyer paddle or a straight key.
