Xiegu G90 Review: The Budget HF Radio That Surprised Everyone

When Xiegu released the G90, the amateur radio community was skeptical. A 20-watt HF transceiver with a built-in antenna tuner for around $420-450? From a Chinese manufacturer most US hams hadn't heard of? The QRZ forums were not kind in early threads.

Street prices in this article were checked in August 2026 and move around; verify with a dealer such as HRO, DX Engineering, or GigaParts before you buy.

That was a few years ago. Since then, the G90 has become one of the best-selling HF radios in its class. POTA activators carry them. New Generals buy them as first HF rigs. Contest operators toss them in go-bags.

I've had mine for about 18 months now. Used it for POTA activations, Field Day, and as my travel radio. Here's what I think after putting serious hours on it.

Specs at a Glance

• Frequency coverage: 0.5-30 MHz receive, 160m-10m transmit (amateur bands)
• Output power: 20 watts max (adjustable down to 1W)
• Modes: SSB (USB/LSB), CW, AM, FM
• Built-in antenna tuner: Yes, automatic, rated for 15-250 ohms (about 3:1 below 50 ohms, 5:1 above)
• Display: Detachable head unit with color LCD spectrum display
• Size: 120 × 45 × 210 mm, about 4.7 × 1.8 × 8.3 inches (head + body connected)
• Weight: about 3.6 lbs (1.6 kg)
• Power supply: 13.8V DC; the ARRL Lab measured 4.4 A at full output, so size the supply for 5-6 A
• Price: $420-$460 USD (street price, varies by vendor)
• IF DSP: Built-in, with adjustable bandwidth, NR, notch filter

Build Quality and Design

The G90 is a two-piece design. The main unit houses the PA, finals, and tuner. The detachable head unit has the display, controls, and IF DSP board. They connect via a ribbon cable for integrated use, or a separation cable if you want to remote-mount the head.

Build quality is... adequate. Not Icom fit-and-finish, but not toy-grade either. The aluminum chassis feels solid. The knobs are decent but not buttery smooth. The buttons have a slightly mushy click. These are not dealbreakers at this price point. The IC-7300 has better build quality, and it should, at 3× the price.

The detachable head design is genuinely clever for portable use. Mount the head on a small tripod or propped up on a table, keep the main body on the ground near the antenna feedpoint. Reduces cable runs.

The Display

This is where the G90 punches above its weight. The color LCD shows a real-time spectrum display and waterfall. Not as detailed as the IC-7300's, but functional and helpful for spotting signals.

In practice, I use the waterfall constantly during POTA activations to see where callers are stacking up. On CW, you can visually spot signals before you hear them in the passband. For a sub-$500 radio, having any waterfall at all was unusual when this launched.

One gripe: the display washes out badly in direct sunlight. If you're operating outdoors (which, given this radio's size, you probably will be), position it in shade or angle it away from the sun. Not a flaw unique to the G90, but worth noting.

Receiver Performance

Look. The G90's receiver is not going to compete with an IC-7300 or a Flex-6400 in a crowded contest environment. The DSP is competent but the dynamic range and close-in performance have limits.

But here's the thing: for portable ops, casual DX, and most real-world operating situations, it's fine. Better than fine. The adjustable IF bandwidth works well, the noise reduction actually reduces noise without making audio sound like you're underwater, and the notch filter tracks adequately.

My measured numbers (your mileage may vary):

• Sensitivity on 20m SSB: around -130 dBm MDS (adequate)
• Audio quality on receive: clear, not harsh. The internal speaker is mediocre but headphones sound good.

I pulled in VP8PJ on 17m SSB during a DXpedition pileup with this radio and a 20m wire antenna. Not a weak-signal contest winner, but not deaf either.

Transmitter and the Built-in Tuner

20 watts isn't a lot. Let's be honest about that upfront. You're not going to bulldoze through a contest pileup on 20m phone with 20W and a compromise antenna.

But 20 watts is plenty for:

• FT8 and other digital modes (most operators run 15-25W anyway)
• CW (the mode efficiency advantage means 20W CW ~ 100W SSB in terms of readability)
• POTA/SOTA activations where chasers are looking for you
• Casual ragchewing when conditions are decent

The built-in tuner is the killer feature. It automatically matches loads from 15 to 250 ohms, roughly 3:1 to 5:1 SWR. For portable ops, this means you can throw a random wire into a tree, clip on a counterpoise, and the tuner handles the matching. No external tuner box to carry.

I tested it with a 35-foot random wire and 17-foot counterpoise. The tuner matched on 40m, 20m, 15m, and 10m without complaint. On 80m it struggled (SWR was above 3:1 to start with), which is expected physics. Longer wire needed.

The tuner takes 2-3 seconds to find a match. Not instant, but faster than most outboard tuners. During that tune cycle, the radio transmits a brief carrier, so don't tune on a frequency someone else is using.

Firmware and the CE-19 Interface

Xiegu has released multiple firmware updates since launch. The current firmware (as of 2024) has fixed most of the early bugs that plagued initial production units. If you buy a G90 today, update the firmware before doing anything else. Seriously.

For digital modes (FT8, JS8Call), you'll need the CE-19 data interface accessory ($50-60). It provides the audio in/out and PTT connections for your computer. It works, but it's an extra purchase that competitors like the IC-705 handle natively via USB.

(The CE-19 cable routing is slightly annoying. It connects to a multi-pin port on the back of the head unit, so if you're using the separation cable, things get messy with cables. My portable digital setup looks like a squid attacked a radio. Not elegant, but functional.)

What I Don't Like

Being straight with you:

• No general coverage transmit. Some operators want this for MARS or other authorized out-of-band operation. The G90 is ham-bands only on transmit.
• Menu diving. Too many settings buried in menus. The IC-705 handles this better with its touchscreen. The G90's button interface for deep settings feels like programming a 1990s VCR.
• The CE-19 shouldn't be separate. A $450 radio in 2024 should have a built-in USB audio codec. Period. This is my biggest complaint.
• 20W limit. Occasionally I want 50-100W, especially on 80m or during poor conditions. The G90 can't get there without an external amplifier.
• Fan noise. The cooling fan kicks in during extended transmit and it's audible. Not loud, but noticeable during quiet receive periods right after transmitting.

What I Like More Than Expected

• CW performance. The keyer is responsive, the sidetone is adjustable, and the narrow filter settings make CW operating genuinely enjoyable. I've done more CW since getting this radio because it makes CW portable ops effortless.
• Size and weight. About 3.6 lbs with the head attached. Fits in a laptop bag. I've taken it on flights as carry-on.
• Power efficiency. About 4.4A at full transmit, under 500mA on receive. A small LiFePO4 battery (like the Bioenno 12V 6Ah) covers a typical activation.
• The tuner. Again. Cannot overstate how much the built-in tuner simplifies portable setups.

Who Should Buy the G90?

Strong buy if you're:

• A newly licensed General looking for an affordable first HF rig
• A POTA/SOTA activator who needs lightweight and portable
• Primarily a digital mode operator (FT8/FT4/JS8Call)
• Building a go-kit or emergency communications package
• Budget-constrained and willing to accept 20W

Maybe look elsewhere if you're:

• A serious contester who needs 100W and top-tier receiver performance
• Operating primarily from a fixed home station (the IC-7300 at ~$1100 is the better value for that use case)
• Allergic to firmware updates and workarounds

The Competition

At the ~$400-500 price point:

• Yaesu FT-891: More power (100W) but no built-in tuner, no waterfall display, heavier. Better for mobile/base, worse for true portable.
• Xiegu X6100: Same manufacturer, has a touchscreen and battery built in, but has had more firmware issues and the community consensus is the G90 is more mature.
• Lab599 TX-500: Beautiful radio, similar concept, but $900+. Different league financially.

The G90 occupies a specific sweet spot: lightweight, built-in tuner, waterfall display, and a price that doesn't require spouse-approval committee meetings.

Final Verdict

The Xiegu G90 isn't perfect. The 20W limit, the external CE-19 requirement for digital, and the occasionally clunky menu system are real drawbacks. But for what it costs and what it delivers, nothing else quite matches the package.

I've owned radios from Icom, Yaesu, and Kenwood. The G90 lives in my go-bag permanently. It's earned that spot.

If you're considering one, buy from a US dealer (Radioddity, GigaParts, or DX Engineering all stock them) for warranty support. Update the firmware on day one. Get the CE-19 if you plan on digital modes. And don't be surprised when a $450 radio gives you more fun per dollar than anything else in your shack.

Not bad for the radio nobody trusted.
