In the last 2 weeks I’ve been working on a software called dmrshark in my free time. It uses libpcap to analyse the traffic of a Hytera IPSC network. It can be used for: Tracking calls, logging to a text file, and/or inserting them to a remote MySQL-compatible database. Automatic and periodic reading of repeater […]

Recently I’ve been working on a Red5 webapp called kdrlivestream which authenticates users using a MySQL database. This will be used for live streaming my radio club’s subscription based remote courses. Red5 has a built-in webapp called live, but it doesn’t use authentication. Everyone will be able to publish and watch streams using your private […]

I’ve written a simple infrared remote control plugin for foobar2000. It’s called foo_ir2. I’ve replaced Winamp about a week ago. I like foobar2000 much better, it has a fully customizable simplistic user interface and lots of advanced settings.


You can use this simple application for triggering PTT on your radio via DTR/RTS COM port pins. It supports remote PTT triggering with ptt2dtr as the server. More…


My Yaesu FT-857D transmits the audio coming from the MIC input instead of the rear line in when PTT is triggered via CAT command. When PTT is toggled with the rear PTT pin, it works as it should. I had to find a solution for this inconvenience, so I wrote ptt2dtr which translates PTT CAT […]

Pictures This is how it looked like when I got it: And this is how it looks like now:

Now it’s working on my desk. It’s pretty strong, I can’t stop it with my bare hands, I hope it’ll rotate my big yagi easily. I’ll perform a full antenna test in our yard tomorrow or on thursday. UPDATE: pictures are here.
