Yaesu FT-891

The Yaesu FT-891 HF All Mode Mobile Transceiver once again continues Yaesu's legacy for legendary receiver design in a compact package, offering uncompromising performance for both the mobile and stationary amateur operator. High-performance 32-bit DSP with floating point DSP improves the operating experience by providing a cleaner, clearer signal and reducing overall user fatigue, creating a more pleasant environment for any amateur operator.

Uncompromising

• Receiver circuit design ensures excellent performance
• Triple conversion with a 1st MF frequency of 69.450 MHz (SSB/CW/AM)
• 3 kHz roof filter available as standard
• TCXO provides ±0.5 ppm high frequency stability (-10°C to +50°C)

Power 100 Watts

The Yaesu FT-891 delivers a stable 100 Watt (25W AM) high output power. High reliability is ensured by the transmitter's careful circuit design with efficient thermostatically controlled dual internal fans and die-cast chassis for heat transfer.

32-Bit IF DSP

The 32-bit high-speed floating Point DSP (max. 3000 MIPS) provides effective and optimized QRM rejection and suppression/reduction (DNR) of the random noise that is often frustrating on the HF bands. The highly optimized AUTO NOTCH (DNF) automatically eliminates dominant beat tones, and the CONTOUR and the APF are very effective tools for suppressing receiver noise during HF band operations.

USB connection

A native USB connection supports PC connectivity with a single cable, allowing full rig control via a virtual serial port connection (VCP).

Features for ease of use

• Large diameter main tuning knob (1.6” / 41mm) with torque adjustment
• Pop-up menu for quick and easy navigation
• Multifunction button
• Large transmit/receive indicator
• Three programmable function keys on the front panel

ATAS (Active Tuning Antenna System)

The Yaesu FT-891 fully supports the ATAS-25 and ATAS-120A Active Tuning Antenna System*, allowing plug-and-play and mobile operation.

*ATAS-120A Active Tuning Antenna System is optionally available

Ultra-compact design

Measuring 155 x 52 x 218 mm, the Yaesu FT-891 is an innovative multi-band, multi-mode mobile/portable transceiver with an ultra-compact and rugged housing.

Optionally available FC-50 antenna tuner

The Yaesu FC-50 is a microprocessor-controlled antenna tuner specifically designed for the Yaesu FT-891 transceiver. The Yaesu FC-50 comes with all necessary connection cables for use and can easily be connected to the FT-891.
