One radio. An incredible range of possibilities.
The Yaesu FT-991A has earned its reputation as one of the most versatile transceivers in the amateur-radio market. Combining HF, 50MHz, 144MHz and 430MHz operation with SSB, CW, AM, FM and Yaesu System Fusion C4FM digital voice, it offers an extensive range of capabilities in a single compact unit.
With 100W output on HF and 50MHz, 50W on VHF/UHF, sophisticated 32-bit DSP filtering, a 3.5-inch colour touchscreen and a built-in automatic antenna tuner, it remains an attractive choice for anyone wanting one radio for a wide variety of operating interests.
From HF DX and CW to local repeaters, C4FM digital communication and computer-based digital modes such as FT8, the FT-991A provides a particularly flexible foundation for a home, transportable or portable station. With the final UK stock now available, it also represents a last opportunity to purchase this long-established model brand new.
Separate HF/6m and VHF/UHF antenna sockets
The FT-991A features two separate rear antenna connections, allowing suitable antenna systems to be connected for different bands.
HF / 50MHz
Female SO-239 socket accepting a PL-259 plug for HF and 6m antennas.
144 / 430MHz
Female N-type socket for 2m and 70cm antenna connections.
All-band performance in a compact package
HF and 50MHz
Full-power HF and 6m operation for DX, CW, SSB and digital modes.
144 and 430MHz
VHF/UHF operation with FM, SSB, CW and C4FM digital capabilities.
Colour Touchscreen
TFT display with touch controls, real-time spectrum scope and waterfall.
ATU Memories
Automatic HF/50MHz antenna matching with memory recall.
See the signals around you
The FT-991A introduced a high-speed, real-time spectrum scope that allows operators to monitor activity around their selected frequency while continuing to listen to received audio. This was one of the most significant enhancements over the original FT-991.
Multi-Colour Waterfall
Observe changing signals over time, helping identify weaker stations and locate activity across the band.
Automatic Scope Control
ASC provides an intuitive way to observe the spectrum and recognise signals near the operating frequency.
A capable receiver with sophisticated DSP
The FT-991A features a high-performance superheterodyne receiver supported by 32-bit floating-point digital signal processing. Its 3kHz roofing filter and adjustable DSP functions help reduce interference and improve reception of wanted signals.
32-Bit DSP
High-speed processing for flexible filtering and clearer received audio.
3kHz Roofing Filter
Helps attenuate strong nearby signals early in the receiver chain.
SHIFT and WIDTH
Adjust the receive passband to reduce adjacent interference.
Noise Reduction
Digital noise reduction, notch filtering and noise blanking for difficult band conditions.
C4FM digital voice and analogue FM
The FT-991A supports C4FM System Fusion digital voice alongside conventional analogue FM operation. This provides compatibility with suitable Yaesu digital stations and repeaters while retaining conventional FM capabilities.
Automatic Mode Select (AMS) can detect compatible FM or C4FM transmissions and select the corresponding receiving mode, making mixed analogue and digital operation more convenient.
Ready for FT8, RTTY and more
Integrated USB CAT control and audio connectivity allow the FT-991A to work with compatible amateur-radio software. With the correct driver and configuration, it can operate digital modes including FT8, FT4, RTTY and PSK31 without the need for a separate external sound-card interface.
The rear RTTY/DATA connection provides additional options for specialised interfaces, while USB also supports compatible transceiver firmware updates and computer control.
Automatic matching with 100 memories
The FT-991A includes a high-speed automatic antenna tuner for supported HF and 50MHz operation. Its 100 memory channels recall previous matching settings to help reduce tuning time when returning to familiar frequencies.
The radio also supports compatible external matching solutions, including the Yaesu FC-40 antenna tuner, for suitable installations.
The built-in tuner is intended for HF and 50MHz operation only. It does not provide antenna matching on 144MHz or 430MHz.
Built for the shack and beyond
Despite its extensive operating capabilities, the FT-991A measures approximately 229 x 80 x 253mm and weighs around 4.3kg. Its manageable dimensions make it suitable for permanent stations and transportable installations.
A substantial heatsink and temperature-controlled cooling system help maintain operating stability, while the adjustable front-panel stand offers a more comfortable viewing angle.
A regulated 13.8V DC power supply is required and is not included. Yaesu specifies approximately 23A current draw when transmitting at 100W on HF. Select a supply with adequate continuous-current capacity.
UK Destination Configuration
Regional frequency settings and amateur-band availability may depend on the radio's destination configuration. Consult the information sheet before making any changes.
