Packet Radio Using Remote Control Through SSH Server

Recently I have been messing with APRS and other packet radio transmissions, and I haven’t really found it to be all that enjoyable in its present form. Don’t get me wrong. I have had plenty of fun with it, but it hasn’t been what I want to do. My previous articles about getting Xastir up and running and sending packets through the ISS show that I enjoyed what I was doing, but the problem is that neither situations were very convenient. With APRS, I had to start up a laptop and initialize the TNC or I had to keep it running and risk killing the car battery. With the ISS I had to be ready to go at a moment’s notice, and since many of the passes were during work hours, I was not able to leave and drive to the clearing to make contact. Now, I think I’ve come up with a solution. Continue reading

Xastir and my KAM TNC (Went with KISS mode)

I found something to occupy my time the last couple of days. I got tired of typing my own APRS positions into a document and sending raw packets to report my position (@240805/3108.03N/08343.16W>000/000/Robbie kk4fgm.com…). Every time I came to a stop at a parking lot and before I exited the vehicle, I took a look at the GPS and the clock and typed the information into a document. Then I sent the raw data in GtkTerm to the TNC. It made my wife mad to have to wait the three to five minutes once we arrived at a destination. Frankly, it made me even more mad because I had to wait for the GPS, open a terminal and VIM a file, then type in the commands to the TNC. I knew that I was going to have to find an automatic program to do this for me. That program is Xastir.

Tech-tut: week of January 24, 2012

I have an apparent abundance of computer parts in my home, but the problem is that hardly any of them go together to make a whole. I wonder how many small-time hoarders such as myself have this problem. I occasionally get broken computers given to me, and most times I have to chop shop them and save what seems salvageable. Last night may have been one of those opportunities that was glorious and annoying at the same time. Continue reading

Ubuntu 10.04.1: Read-only file system?

I had an unfortunate event happen to my HP Pavilion zv6000 laptop tonight.  I had been listening to Internet radio in the shower (no, the laptop wasn’t in the shower), and I left it on the counter to play music all day. My wife complained about the music this evening so I took it back into my study-work room/junk area. Continue reading
