FreeData is "a free, open-source, multi-platform application for sending files and messages, using the codec2 HF modems." [1]
Of course, I'm an amateur radio operator, also know as a ham. And, if you read this blog at all, you know I'm pretty into Linux and open-source software. So, it should …
Hopefully you read the last article I posted about building an Arduino TNC to perform packet email (Winlink) with my Android cellphone and Baofeng handheld radio. If not, I recommend that you check it out so that this post will make more sense.
After completing the hardware section of the …
Recently, I decided that I would put some of these great components that I have lying around to work. I've been doing a lot of Winlink lately, and messing around with my dilapidated Baofeng UV5R. So, I decided to intertwine the two projects. I decided to build an Arduino TNC …
A slightly different post today, and certainly not my usual style. Opinion pieces are not usually my thing, but today I played a chess game that made me stop and think about the current chess scene allegations.
Above is a game of chess that I …
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 …
One of my favorite methods of communication via HF radio is winlink. Despite the name, it is not Windows operating system centric. It is just a method of using an e-mail based system that works over radio waves. For that to work however, you need protocols. There are several to …
