I am a licensed radio amateur ("ham") with the call sign DJ5CW (formerly DJ1YFK). I love Morse Code (CW), especially at high speeds. To foster its usage and to preserve it for the future, I developed Learn CW Online (lcwo.net), a web-based Morse course and practice tool with an active community of a few thousand users.

Studies / Lecture Notes

During the first semesters of my studies of electrical engineering at Dresden University of Technology (2003 - 2005), I transcribed some lecture notes in LaTeX. Over a decade later, they are still used by many students. Everything is available as PDFs and LaTeX sources, licensed under the terms of the CC-BY license.
