In this video I dig into the new Xiegu G7250 and start reverse-engineering what’s happening under the hood. Using the radio’s USB serial connection, I capture the 115200 baud boot sequence, inspect STM32 debug output, identify GT911 touchscreen configuration data, watch the radio switch into post-boot binary traffic, and trace what happens when the VFO is turned. The goal is simple: figure out whether there’s a hidden shell, service interface, or other undocumented way into the G7250.

I also explore the G7250’s Ethernet interface and network configuration, including the radio’s 192.168.3.199 address, configured port 50001, ping response, Nmap scans, and the mysterious `SLIP Client` message that appears during startup. Along the way I test serial BREAK, keyboard escape attempts, Linux SLIP networking, raw hex captures, and the radio’s exposed configuration files to see how much of the underlying STM32/Linux-style architecture can be uncovered without opening the case.

This is not a teardown or finished exploit. It’s the first round of hands-on Xiegu G7250 hacking and firmware investigation, with plenty of clues but no shell prompt yet. If you’re into ham radio hacking, SDR reverse engineering, embedded Linux, STM32 development, serial debugging, Ethernet protocol analysis, CI-V style traffic, or figuring out how modern software-defined radios actually work, this one goes straight down the rabbit hole.

I bought another returned AnyTone AT-5289 II expecting the usual mystery: broken radio, weird settings, or maybe nothing wrong at all. The radio itself actually checked out fine. Then I tried to use the programming software, and that’s where the wheels came off.

The Xiegu G7250 is finally here. In this first-look video, I unbox the new Xiegu G7250, walk through the controls, menus, display, operating modes, and overall first impressions before putting it on the air. This is not a full review yet, just a hands-on look at what comes in the box and what the radio is actually like to use.

After getting familiar with the G7250, I connect it to the antenna and see what it can do on HF under less-than-ideal band conditions. Despite a rough day on the bands, the radio manages a solid first contact, giving us an early look at its receive audio, transmit performance, tuning behavior, and real-world usability.

There is plenty more to test on the Xiegu G7250, including output power, receiver performance, digital modes, CW, filtering, firmware, heat, spectral purity, and long-term reliability. If there is something specific you want to see tested, leave it in the comments and I’ll add it to the list for the full review. #Xiegu #G7250 #HamRadio
