In previous posts, I "fixed" my UV5R which had a bad battery by soldering on a connection by soldering on a power connector for a standard 9 volt battery. In those photos, you could see that I just taped the battery to the back of the case and used the …

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 …

Last post I wrote about trying to use my Owon handheld oscilloscope (HDS242) with Linux. I had tried several options, and among them was one called OwonOszi. At the time, I didn't build it because it was written in pascal. I've never worked with pascal before, and was mistaken to …

Recently, I acquired a new Owon HDS242 handheld oscilloscope. Overall, I'm really impressed with it and it is amazing to see technology continue to progress. This handheld unit is about the size of the average multi-meter, but can do more than my old desktop o-scope that was the size of …

The OPcache interned strings buffer is nearly full. To assure that repeating strings can be effectively cached, it is recommended to apply opcache.interned_strings_buffer to your PHP …

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 …

Typically, updating minor versions of Nextcloud is a straightforward and smooth process. Today's update wasn't much different, but did require some admin intervention on my part. After the update, there was a note abouit missing indices, again. This seems to be fairly regular in NC updates, but doesn't happen every …
