Recently I was looking for alternatives to allow me to send Winlink messages over the 2m band via packet. One of the problems that I can't seem to solve on Linux is making AX.25 and Direwolf work properly. I've read through (and followed) a dozen tutorials, but no matter …
This Baofeng UV-5R was the first radio I ever purchased after getting my license. Actually, it was just plain the first ham related radio I ever purchased. But, it didn't last long, within a year the unit quit working. I realized that it just needed a new rechargeable battery, but …

Recently I was gifted a used tablet from a friend. It is a Vulcan Excursion 10.1" tablet that came stock with Windows 8.1 and was upgraded to Windows 10. Of course, I love free tablets, but I'm not a Windows fan, so I wiped it and put Ubuntu …
