Linux Kernel Drops AX.25 and Amateur Radio Subsystem Support
Earlier today Linus Torvalds merged a pull request to remove AX.25 and hamradio subsystem support from the Linux kernel. While the headline sounds ominous, most modern AX.25 implementations occur in software at the user level without relying on the kernel level implementation. Direwolf, for example, does not require kernel level AX.25 support. Other software relying on AX.25 may take advantage of dedicated AX.25 Python libraries.
The change comes as a result of AI based bug detection services capable of identifying critical issues among code that may no longer be maintained or utilized by end users. Torvalds stated that the amateur radio related code in the Linux kernel no longer had any active maintainers:
Amateur radio did have occasional users (or so I think) but most users switched to user space implementations since its all super slow stuff. Nobody stepped up to maintain the kernel code.
According to typesense the last Linux kernel commit related to AX.25 was 6 years ago.
Additional code removed includes ISDN support, bus mouse support, and various network drivers including support for old 3Com devices.

DX Engineering Gearing Up for Dayton Hamvention® 2026!
Watch two new videos to get you ready for the fun in May!
***
It’s hard to believe that Dayton Hamvention®, May 15-17, 2026, is less than a month away!
At DX Engineering, getting ready for this annual celebration of everything amateur radio—only about three hours south of DX Engineering headquarters in Tallmadge, Ohio—starts soon after we tear down our booths and say farewell to the Greene County Fairgrounds and Expo Center in Xenia.
Our first thought: What can we do to make next year’s event even more special for the thousands of amateur operators who attend?
Here’s a preview of what you can expect in 2026:
Contest University
The day before Hamvention kicks off, another event with a long history of helping hams thrive takes place only a short drive from Xenia—Contest University. It’s a full day of learning hosted by Tim Duffy, K3LR, DX Engineering CEO, and a faculty of some of the most accomplished contesters on the planet.
Registration is still open. Click here and sign up now if you don’t want to miss out. The latest edition of this information-packed event will be Thursday, May 14, 7 am to 5 pm at the Hope Hotel on Wright-Patterson Air Force Base in Fairborn, Ohio.
To get an idea of why Contest University is not to be missed, watch this video from DX Engineering media partner Q5 Worldwide Ham Radio:
Giving Back
You’ll feel good knowing that when you stop by the DX Engineering booths in Building 1 at the fairgrounds, you’re supporting a company that believes in giving back to the amateur radio community. In addition to sponsoring DXpeditions and contributing to youth operator programs, DX Engineering recently donated a fully equipped Hummer with an HF mobile station to the Dayton Amateur Radio Association (DARA).
Pictured below is Tim, K3LR with DARA treasurer and Dayton Hamvention® spokesperson Michael Kalter, W8CI. As the host of Hamvention, DARA plays a vital role in bringing the ham radio community together each year. DX Engineering was honored to contribute to their ongoing effort and the future of amateur radio.

Make Eyeball QSOs with the DX Engineering Team
Once again, DX Engineering’s active hams, who have a combined 1,000-plus years of amateur radio experience, will be available from the moment gates open at 9 am on Friday until the final bell at 1 pm on Sunday. You won’t find a friendlier, more knowledgeable group of operators anywhere. Their goal: Help you find the exact gear you need for your station. You won’t get a sales pitch on purchasing equipment beyond your requirements—just honest, straightforward guidance on what’s best for you and your operating goals.
Bring your technical questions and be ready to swap stories about battling pileups! Our folks love to talk ham radio.

Icom Teases X-023 Radio to be Revealed at Hamvention 2026
In a reel posted to Facebook, Icom has teased a new radio, the X-023 to be revealed at Hamvention 2026. Dubbed as a “concept mock-up,” the radio appears to be a mobile rig based on the focus of a vehicle through most of the video. The radio also appears to have a detachable faceplate and support multiple antenna inputs.
From hamlife.jp:
It is a separate machine that separates the main body from the main body and the operation part (display) from the image, and the operation part has four dials around the display (upper, lower and right), and the lower left part is a large size. From its shape, it seems to be a different model from the 144 / 430MHz band D-STAR / FM mobile machine “ID-5200” exhibited at last year’s “Ham Fair 2025”.
