Yaesu FT-991A

The Yaesu FT-991A is a fully featured, all-mode transceiver designed to cover HF, VHF, and UHF bands in a single compact package. Built for versatility, it caters to both new and experienced amateur radio operators who want full-spectrum coverage and digital signal processing without needing multiple radios.

This radio combines Yaesu’s reputation for durability with cutting-edge features like real-time spectrum scope, advanced digital signal processing (DSP), and a high-resolution touchscreen interface. When you’re chasing DX on 20 meters or checking into a local repeater on 2 meters, the FT-991A delivers reliable, clean audio and top-tier functionality.

Band Coverage: True All-Band Versatility

One of the most powerful aspects of the FT-991A is its broad band coverage. It supports all amateur bands from 160 meters through 70 centimeters, which means operators can enjoy:

  • HF (1.8–30 MHz) for long-distance DX and contesting
  • 6 meters (50 MHz) for seasonal propagation and local nets
  • 2 meters (144 MHz) for local repeaters and simplex communication
  • 70 centimeters (430 MHz) for urban communication and satellite work

Because it covers so many bands, the FT-991A is ideal for limited-space shacks, mobile operation, or portable field work where a single-radio solution is preferred. Moreover, it handles SSB, CW, AM, FM, and digital modes making it one of the most flexible transceivers in its class.

Features and Their Functions

The FT-991A includes a long list of features that enhance performance, usability, and signal quality.

1. Real-Time Spectrum Scope

Unlike older models, the 991A displays real-time band activity with a live spectrum scope. Therefore, you can visually identify active frequencies and tune precisely to where the action is. This feature makes DX hunting and contest operation much easier.

2. 3.5″ Full-Color TFT Touchscreen

The front-panel display is a high-resolution TFT screen with a touch interface. You can change modes, settings, and frequencies directly from the display. Additionally, the vivid colors and sharp contrast make it easy to use in low-light or outdoor conditions.

3. Advanced DSP (32-bit Floating Point)

At the heart of the FT-991A is a 32-bit DSP system that filters noise, reduces interference, and improves weak-signal reception. As a result, signals that would be unreadable on less capable rigs come through cleanly.

4. Automatic Antenna Tuner

The built-in tuner covers the entire HF and 6-meter bands. It automatically matches your antenna system, ensuring optimal transmission and protecting the finals from mismatch damage. Although it’s not designed for large mismatches, it handles typical tuning needs well.

5. 100 Watts of HF Output / 50 Watts on VHF/UHF

On HF and 6 meters, the radio outputs a full 100 watts, while VHF and UHF operate at 50 watts. Consequently, it’s powerful enough for base station use but efficient enough for portable and emergency setups.

6. USB Connectivity

The rear-panel USB port enables easy interfacing with digital modes like FT8, PSK31, and RTTY. It carries both audio and CAT control, so you don’t need external interfaces or sound cards.

7. IF Roofing Filters

To combat interference in crowded band conditions, the FT-991A employs effective roofing filters in the first IF stage. These filters reduce adjacent signal overload and improve signal clarity during contests or pileups.

8. Compact Form Factor

Even with all its features, the radio maintains a compact footprint. It’s smaller than many HF rigs, making it suitable for go-kits, RVs, or desktop installations where space is limited.

TFT Screen and User Interface

The 3.5-inch touchscreen display is more than just eye candy, it transforms the way operators interact with the rig. The touch-sensitive interface allows:

  • Direct frequency input using an on-screen keypad
  • Quick access to menus without deep diving through buttons
  • Real-time spectrum and waterfall display, aiding signal identification

Furthermore, the layout is intuitive and logically organized. This reduces learning curves and lets users focus more on operating than on navigating menus.

The screen also adjusts brightness and contrast, making it easily readable in both daylight and dark environments. With dedicated meters for power, SWR, ALC, and modulation, it delivers all vital information at a glance.
