@Stevesummersell_K4WXX wonders if a 1:1 balun can just be used as a replacment for a coax coil you would put to prevent Common Mode Currents.

Tackling my first solo parks on the air activation at Galveston Island State Park using CW.
Setting up at the park by myself brings new challenges. The focus here is on the fundamentals of making a contact, not necessarily completing the full log. It is a practical look at how I handle equipment setup and operation in the field for outdoor radio.
Learning the rhythm of operating morse in a real-world environment is a major milestone. While this session is about getting comfortable with the process, the experience reinforces the core principles of ham radio.

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.

👉 TOADs Digital Interfaces: https://temporarilyoffline.com?utm_content=G7250Hack
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.

In this video, I tackle the trunk installation for the new mobile ham radio after finding out the old bracket mounting holes didn’t line up. Watch as we secure the new mounting bracket using self-tapping screws and get the radio firmly in place. Once powered up, we run a quick on-air simplex test on .52 with Bill (K0WHW) from the Think Lab campus.

This Amazon Return Worked Fine… The Software Didn’t
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.

In this video I test the radio, try the official and third-party programming paths, dig into the firmware/update mess, and show exactly where the user experience falls apart. The radio passed. The software story… not so much.
