The Yaesu FT-991A is the next generation all-mode, all-band MF, HF, VHF and UHF transceivers with digital C4FM (System Fusion) capabilities. The Yaesu FT-991A features multi-mode operation on CW, AM, FM, SSB and digital modes (Packet, PSK31, RTTY and C4FM), with 100 Watt HF/50MHz capacity (50 Watt VHF/UHF).

This new Yaesu FT-991A is equipped with a high-resolution 3.5-inch TFT touchscreen for superior control and clear readability, with a High Speed ​​Spectrum and a high-resolution real-time scope and built-in ASC (Automatic Spectrum scope control).

For all applications and work areas the Yaesu FT-991A is suitable, whether you work mainly at home, mobile or in the field, the Yaesu FT-991 delivers excellent performance and gives you easy access to the full range of modes available today on the ham bands.

Real-time spectrum scope with Automatic Scope Control (ASC)

The new dynamic real-time spectrum range gives radio operators the ability to graphically view the location of signals on the band while listening to the received audio, allowing them to quickly navigate to the desired signal. The strength of the signals on the band is easy to see on the multi-colored waterfall display. Color differentiation in chronological order allows operators to easily recognize weak signals at a glance; signals that would otherwise be missed on the spectrum range. Advanced Spectrum Scope with ASC (Automatic Spectrum-Scope Control) just below the LCD screen gives the operator all the information for comfortable QSO on the DX scene.

Multi-coloured display

The Yaesu FT-991A now includes a real-time multi-color waterfall display that allows you to quickly and easily identify and pick up signals without having to mute the received audio. Advanced 32-bit digital signal processing system. The Yaesu FT-991A recognizes the all-important Golden Rule of amateur radio - "You can't operate 'em if you can't hear 'em" - and features a rugged, state-of-the-art, highly balanced receiver circuit configuration. The high-speed floating point TMS320C6746 DSP chip (3000 MIPS / 2250 MFLOPS) from Texas Instruments used in the receiver design guarantees excellent suppression of interference with real signals under real conditions, not only on HF but also in the VHF and UHF bands.

3kHz roof filter

The Yaesu FT-991A includes a 3Khz triple conversion receiver roof filter that effectively attenuates spurious signals and enables excellent performance while still producing high quality audio.

3.5-inch TFT color screen

The Yaesu FT-991 offers all functions at a glance with the 3.5-inch TFT color screen.

USB compatible

The Yaesu FT-991A can be connected to a computer using a USB cable to perform CAT control and firmware updates or to use an integrated SCU-17 interface unit to support USB Audio In/ Out, TX Control (PTT, Key, Shift).

100 Watts of solid performance

The RF amplifier in the Yaesu FT-991A delivers a clean, stable 100 Watt operating power (50 Watt VHF/UHF) and is combined with a large heat sink and automatic air cooling fan to extend operating time and prevent overheating.

Compact, lightweight and portable

The Yaesu FT-991A Comes in a compact, lightweight package suitable for portable, mobile and basic installations. Measuring 8.8" (W) x 3" (H) x 9.9" (L) and weighing just 4.3kg, this rugged, fully featured mobile/portable radio is ready to go wherever and whenever you are!
