FT-891 100W HF/50MHz Transceiver - All Mode
The Yaesu FT-891 is an amateur HF transceiver covering the 160 to 6 meter bands, with 100 watts. It features a triple conversion general coverage receiver tuning 30 kHz to 56 MHz. Modes include AM, USB, LSB, and CW. DSP technology supports QRM and noise reduction, auto notch, and APF audio peak filter. Other features include: attenuator, 4-60 WPM keyer, TCXO, CAT port, auto power-off, full break-in, backlit LCD display, and backlit keys. This radio is easy to use. The large tuning knob (1.6") has torque adjustment. All front panel keys are located in logical positions for simple and quick access to frequently needed controls. For example, a multi-function knob allows quick adjustment of the operating frequency in 500kHz steps. The QMB key is useful for quick memory bank storage of 5 priority memories for quick recall. Three other front panel keys can be programmed to user preferences.
The detachable front panel features a large dot-matrix LCD display with a fast spectrum analyzer. The TX/BUSY on the front panel clearly communicates the operator on the current status of the transceiver (for example --- it lights green when receiving signals while the squelch opens and turns red for transmitting. There is a USB port for PC connection (CAT control, audio interface, PTT/RTTY control).
The FT-891 comes with: MH-31A8J hand microphone, microphone clip, MMB-82 mobile mounting bracket, spare fuse, manual, safety guide, and DC power cable. It requires 13.8 VDC at 23 Amperes. 6.1 x 2 x 8.6 inches (155x52x218mm).

DETAILS:
ULTRA COMPACT DESIGN:
With dimensions of 155 x 52 x 218 mm, the GT-891 is an innovative multi-band transceiver, an ultra-compact and robust mobile or portable transceiver.
SOLID AND RELIABLE FINAL STAGE:
The FT-891 delivers stable 100W power (25W AM). The high reliability of the final circuit is ensured by the careful circuit design and the integration of two high-efficiency fans controlled by thermistors.
THE HISTORIC DESIGN OF YAESU RECEIVERS ENSURES EXCELLENT PERFORMANCE:
- Triple conversion receiver with a first IF frequency at 69.450 MHz (SSB/CW/AM);
- 3 kHz roofing filter as standard;
- The TCXO module ±0.5 ppm ensures very high frequency stability (-10 to +50°C)
THE IF DSP PROVIDES EFFECTIVE AND OPTIMIZED QRM REDUCTION:
The high-speed 32-bit DSP (max. 3000 MIPS) offers effective (DNR) QRM reduction, which is often very annoying on HF frequencies. In addition, the AUTO NOTCH (DNF) automatically eliminates higher tones that disturb reception. CONTOUR and ARF are very useful tools for noise reduction during HF band operations. Traditional YAESU QRM reduction functions are all available on the FT-891.
100-CHANNEL MEMORY AUTOMATIC ANTENNA TUNER (OPTIONAL):
The FC-50 is an antenna tuner designed specifically for the FT-891. Connecting the FC-50 to the FT-891 is extremely simple.
FEATURES:
- Large dot-matrix LCD display with Fast Spectrum Analyzer;
- Three multi-function buttons on the front panel fully programmable by users;
- The USB port allows connection to a PC with a single cable (CAT control, PTT/RTTY control);
- The TUN/LIN connector allows connection of the FT-891 to its FC-50 tuner or a linear amplifier;
- State-of-the-art electronic keyer (4 to 60 WPM) with FULL BK-IN operation capability;
- Supports ATAS (Active-Tuning Antenna System) antennas (ATAS-120A, ATAS-25: Option)
