Here you can find Amateur Radio related software I have written for various platforms. Some software is Open Source and some is not. I also maintain some pages here describing software that I no longer maintain due to the completion of its life cycle.

Currently I am most active on the Windows 7 and 8 platform developing .Net applications in Visual Basic and (now mostly) C#, but also use Javascript and HTML to write gadgets for the Windows Vista/7/8 Sidebar. Some applications, like Airlink Express, are hosted on their own web site.

The following software products are not maintained anymore because they reached the end of their life cycle. Of course the software is still fully functional and is listed here for reference purposes. That does not mean that these products have become public domain!

Cybiko UI Frame (APRS) Software Suite
The Cybiko is a small wireless handheld computer that's just a little bit larger than a PDA. It was designed for teenagers to play video games and "chat" with others who have Cybikos. For this platform I wrote APRS software so that these versatile computers can be combined with a Terminal Node Controller (TNC) and a GPS device to build a tracker, an instant messaging and mapping device, or a gateway between the 2 meter Amateur Radio APRS network and 900MHz FCC Part 15 network all Cybikos reside on.
