Yaesu FT-991A Radio Review: A Versatile All-in-One Transceiver
The Yaesu FT-991A is one of the most versatile and compact all-band, all-mode transceivers available for amateur radio operators. Designed for HF, VHF, and UHF operations, it covers everything from 160 meters to 70 cm, with support for modes like CW, SSB, AM, FM, and digital (including Yaesu’s C4FM). Whether you’re into DXing, contesting, or simply working local repeaters, the FT-991A offers a powerful, portable package for all your operating needs. Here’s an in-depth look at the features, strengths, and any potential drawbacks of this radio.
Key Features of the Yaesu FT-991A
1. All-Band, All-Mode Coverage
The FT-991A covers HF (160m-10m), VHF (6m and 2m), and UHF (70cm), making it one of the few radios that offers complete coverage in a compact unit. With 100 watts on HF/6m, 50 watts on 2m, and 35 watts on 70cm, it packs enough power for nearly any operating scenario.
- SSB, CW, AM, and FM modes are fully supported across all bands.
- Digital modes like PSK31, RTTY, and FT8 are easily accessible with a simple USB connection to your computer, no external sound card required.
2. Color Touchscreen Display with Spectrum Scope
One of the standout features of the FT-991A is its 3.5-inch color TFT touchscreen, which adds significant usability to the radio. The display includes:
- Real-time spectrum scope: It provides a live view of band activity, which is especially helpful for locating signals quickly.
- Waterfall display: This is useful for visualizing weak signals over time, especially on digital modes.
While the screen isn’t as advanced as those on high-end SDR rigs, it’s impressive for a radio in this price range.
3. Digital Signal Processing (DSP)
The advanced DSP in the FT-991A is a key selling point. The radio offers excellent signal clarity and noise reduction, thanks to features like:
- Automatic Notch Filter (DNF): Helps eliminate unwanted carriers or interference.
- Noise Reduction (DNR): Reduces background noise to improve signal readability.
- Contour Control: Tailors the audio response to improve clarity in weak signal conditions.
These tools make weak signal work easier, especially on HF, where atmospheric noise can be a challenge.
4. Internal Automatic Antenna Tuner
The built-in automatic antenna tuner works quickly and efficiently on HF and 6m bands, allowing you to use antennas that might not be perfectly resonant. This is a huge convenience, particularly for portable or field operations where antenna tuning can be tricky.
5. C4FM Digital Voice (System Fusion)
If you’re interested in digital voice modes, the FT-991A has full support for Yaesu’s System Fusion (C4FM), making it compatible with Wires-X and System Fusion repeaters. The digital voice quality is excellent, and it provides easy access to Yaesu’s growing global digital network.

Performance Review: HF, VHF, and UHF
HF Performance
On HF, the FT-991A holds its own even in challenging band conditions. The receiver is sensitive, and the DSP filtering does a great job of pulling signals out of the noise. For DXing and contesting, the 100-watt output provides enough power to make contacts worldwide, while the adjustable RF power control is perfect for QRP operations.
The spectrum scope is a handy tool for spotting band activity, but it’s not as fast or detailed as some high-end SDR radios. Nonetheless, it serves its purpose well for casual band exploration.
VHF/UHF Performance
The VHF/UHF performance on 2m and 70cm is excellent, with 50W and 35W of output power, respectively. This makes it great for local repeater operations, simplex contacts, and even satellite work. The FT-991A’s dual FM and C4FM modes allow for seamless transitions between analog and digital operations, making it very versatile for both local and digital voice communication.
Digital Mode Performance
The FT-991A shines in digital modes (e.g., FT8, PSK31, RTTY), especially since it can connect directly to your computer via USB without needing an external interface. The built-in sound card simplifies setting up digital modes with popular software like WSJT-X or FLDigi, making it easy to jump into digital operation right away.

Ease of Use and Setup
Menu Navigation
The FT-991A offers a lot of features, but this also means there’s a bit of a learning curve when it comes to the menu system. While the touchscreen makes navigating easier, many settings are buried deep within submenus, which can be frustrating until you become familiar with the layout.
Portability and Build
Weighing just under 10 lbs, the FT-991A is relatively lightweight and compact, making it ideal for portable and field operations. It’s sturdy enough for regular use as a base station but small enough to take on the go, particularly for Field Day or SOTA (Summits on the Air) activities.

Pros and Cons of the FT-991A
Pros:
- All-band, all-mode operation: The ability to cover HF, VHF, and UHF with one radio is a huge advantage, especially for those with limited shack space or who want a single rig for portable and base station use.
- Excellent DSP: Features like noise reduction, notch filtering, and contour control make weak signal work much easier.
- Touchscreen display with spectrum scope: Enhances usability and adds a modern touch to the interface.
- System Fusion (C4FM): If you’re into digital voice modes, having built-in support for Yaesu’s C4FM is a big plus.
- Built-in USB for digital modes: Makes connecting to digital software seamless without requiring extra hardware.
Cons:
- Spectrum scope limitations: While the real-time spectrum scope is a great feature, its resolution and refresh rate are not as robust as standalone SDR radios or higher-end rigs.
- Complex menu system: With so many features packed into one radio, it can take time to learn and master all the settings and menu options.
- Only one antenna port: The FT-991A has a single antenna port, so if you want to switch between HF and VHF/UHF antennas, you’ll need to use an external switch or manually swap cables.
