Writing software is one of my other time consuming activities apart from ham radio. My programming career started in the early 80's with BASIC and via high level languages such as Pascalc en C and with certain degree of fanaticism in whatever I'm doing, I finally ended up creating DOS software in assembly. To move with times I started writing Windows software using the assembly language in 2004. Below a few samples of software created while learning to master Win32 assembly. Please note that this software was created for Windows XP and won't work with earlier versions of Windows.

Visit my Programming page for a description of the following software.

WWLoc is a utility for amateur radio operators to convert the classical latitude/longitude coordinates to the Maidenhead locator system and vice versa. Created using assembly, it's a very tiny program of only 9.5 KB.
