Real-time spectrum scope with ASC
The FT-991A’s dynamic real-time spectrum range allows operators to visually locate signals on the band while listening to the received audio. Signal strength is easily visible on the multi-color waterfall display, making weak signals that would otherwise be missed visible.
Multi-color 3.5-inch TFT color display
The Yaesu FT-991A features a real-time multi-color waterfall display, allowing you to quickly and easily identify signals without muting the received audio. This display provides a visual representation of signals and their strength, making it easy to navigate through the bands. The 3.5-inch TFT color screen displays all functions at a glance, with clear and bright information and settings
Advanced 32-bit DSP system
The FT-991A features a high-speed floating point DSP chip from Texas Instruments, which provides excellent interference rejection. This ensures superior reception on both HF and VHF/UHF bands.
3kHz roof filter
The built-in 3kHz roof filter effectively attenuates interfering signals and delivers high performance without sacrificing sound quality.
USB compatibility
The FT-991A can be connected to a computer via a USB cable for CAT control, firmware updates, and support for the integrated SCU-17 interface for USB Audio In/Out and TX Control.
100 Watts of solid performance
The RF amplifier delivers stable 100 Watts (50 Watts on VHF/UHF) power, with a large heat sink and automatic air cooling fan to prevent overheating and extend operation time.
Compact and portable
