The Yaesu FT-891 HF All Mode Mobile Transceiver is a compact yet powerful device that continues the legacy of Yaesu's legendary receiver design. It offers uncompromising performance for both mobile and stationary Amateur operators. The transceiver features a high-end 32-bit floating-point DSP, which enhances the operating experience by providing a cleaner and clearer signal, reducing operator fatigue, and creating a more enjoyable environment. The receiver circuit design ensures excellent performance with triple conversion and a 1st IF frequency of 69.450 MHz for SSB/CW/AM modes. It is equipped with a 3 kHz roofing filter as a standard feature. The TCXO provides ±0.5 ppm high-frequency stability (-10°C to +50°C). The FT-891 provides a stable 100 Watts (25W AM) of high power output, backed by careful circuit design, efficient thermostatically-controlled dual internal fans, and a die-cast heat-transferring chassis for high reliability. The transceiver's 32-bit IF DSP offers effective and optimized QRM rejection, cancelling/reducing random noise on the HF bands. It also features AUTO NOTCH (DNF) for eliminating dominant beat tones, and CONTOUR and APF for receiver noise reduction during HF band operations. The native USB connection allows for complete rig control via a virtual serial port connection (VCP). The FT-891 is designed for ease of operation, with a large diameter main tuning dial, a pop-up menu for quick navigation, a multi-function knob, a large transmit/receive indicator, and three programmable front panel function keys. It fully supports the ATAS-25 and ATAS-120A Active Tuning Antenna System for plug-and-play field and mobile operation. Despite its powerful features, the FT-891 has an ultra-compact and rugged case design, measuring 6.1" x 2.0" x 8.6" (155 x 52 x 218 mm). It also offers the option of coupling with the FC-50 Antenna Tuner Unit, which is designed specifically for the FT-891. In the box, you will find the FT-891 Transceiver, DC Power Cable, MH-31 Microphone, Mobile Mounting Bracket, and FT-891 User Manual. The transceiver comes with a 3-year warranty when purchased new. Its specifications include a frequency range of 1.8 - 54.0MHz for TX and 30 kHz - 56 MHz for RX. It operates on various modes of emission, including A1A (CW), A3E (AM), J3E (LSB, USB), and F3E (FM). The transceiver has a 50 Ohm unbalanced impedance and operates on a supply voltage of 13.8VDC +/- 15%, negative ground. The current consumption is 2.0 A in Rx mode and 23A in Tx mode. It has an operating temperature range of -10 °C to +50 °C and weighs approximately 4.18 lbs (1.9 kg). The output power is 100W SSB/CW/FM and 25W AM. The receiver circuit design includes triple conversion for SSB/CW/AM and double conversion for FM. The transceiver has various sensitivity levels for different modes and frequencies. The audio output impedance is 4 to 16 ohms, with a nominal value of 8 ohms, and the maximum AF output is 2.5W at 4 ohms with 10% THD. The FT-891 is a reliable and feature-packed transceiver that offers excellent performance in a compact design.
