Xiegu G90 HF Radio Review Wide-Range SDR with Built-in Auto Antenna Tuner

Description

Versatile and Compact: The Xiegu G90 HF Radio

Testing out the Xiegu G90 HF Radio with DE-19 Expansion, I quickly realized why this device has been creating a buzz in its niche. It’s a lightweight, feature-rich SDR (Software Defined Radio) that targets amateur radio enthusiasts. With its 20W power output and built-in auto antenna tuner, it offers a lot of flexibility. My experience with it wasn’t without a few quirks, but the overall performance left me impressed.

Design and Build Quality

The detachable display unit is one of the first things that caught my attention. Being able to separate the display from the radio body is more than just a gimmick; it’s a practical feature. You can mount the display in a convenient spot while placing the main unit elsewhere, which is ideal for tight spaces or mobile setups. The LCD screen is another highlight—its vivid color display is not only easy on the eyes but also provides detailed operating information in daylight.

Durability seems to be a priority in its design. The materials feel solid, and while I haven’t dropped it (yet), it feels like it could handle some rough use. The buttons and knobs are responsive, and the layout is intuitive, which is a big plus when you’re fiddling with settings mid-operation.

Performance and Features

This radio is equipped with a wide-range internal automatic antenna tuner, and let me tell you, it’s a lifesaver. Unlike other QRP radios, it adapts quickly to different antennas, making field operations much smoother. I tested it with my usual field antenna, and the tuner handled it effortlessly. The 48KHZ wide spectrum display with a waterfall feature isn’t just for show—it gives you a clear understanding of nearby signals, which is incredibly useful in crowded bands.

What really stood out during operation was the DE-19 expansion with digital isolation technology. This feature ensures compatibility across various electrical power levels and worked seamlessly when I connected it to my computer. The device also includes a mediumwave (AM broadcast) high-pass filter, a feature I didn’t know I needed until I saw the difference in signal clarity.

Positives

Highlighting some of the key benefits:

• The detachable display unit adds versatility for different setups.
• The built-in auto antenna tuner simplifies field use by adapting to various antennas.
• The color LCD screen provides excellent visibility and operational awareness.
• The DE-19 expansion enhances compatibility and performance for digital connections.

Less Favorable Aspects

While the radio performed well overall, there were some areas for improvement:

• The user manual could be more detailed; I had to dig around online forums for some settings.
• The power output, while adequate for most tasks, might feel limiting for heavy users.
• The learning curve is a bit steep if you’re new to SDR radios.

Competing Products

Comparing the Xiegu G90 to other popular radios in the same category, like the Yaesu FT-818ND and the Icom IC-705, reveals some interesting contrasts. The Yaesu FT-818ND is compact and rugged but lacks the modern SDR capabilities that the G90 excels in, such as the color spectrum display and waterfall feature. Meanwhile, the Icom IC-705 offers a higher power output and a sleeker interface but comes at a significantly higher price point.

Where the Xiegu G90 wins is in its balance of affordability and functionality. Features like the built-in tuner and detachable display unit make it more versatile than the Yaesu, while its price makes it a more accessible option compared to the Icom. However, its slightly lower power output might make it less appealing to operators who need more range.

Cost-Effectiveness

Evaluating the cost-effectiveness of the Xiegu G90, it offers a lot for its price tag. Radios with similar features often cost considerably more, and while there are a few trade-offs—like the lower power output—it still provides excellent value for the money. The 18-month warranty adds peace of mind, though it’s worth noting that modifying the hardware voids this protection.

Given the combination of features such as the DE-19 expansion, wide-range tuner, and spectrum display, it’s a solid investment for hobbyists and semi-professional operators alike. You’re essentially getting a high-performing SDR radio without the premium price tag often associated with similar devices.

Final Thoughts

This radio isn’t perfect, but its combination of usability, flexibility, and features makes it a standout option in its category. Whether you’re an experienced operator or a newcomer looking to dive into amateur radio, it’s a device worth considering. While it may not outperform some higher-end models in raw power, it more than makes up for it with its modern features and thoughtful design. It’s definitely a tool I’ll be keeping in my setup for the foreseeable future.
