On these pages you can find descriptions of a few ham-radio related projects. Most recent is information on how to get started with writing your own application programs for the AVR series of controllers. All applications have been written in Bascom, a Basic implementation for AVR controllers.

I would appreciate your feedback, there is probably quite some room for text improvement...

You will find some old stuff, mainly about finished homebrew projects, at the bottom of this page.

Getting started with AVR and Bascom.

Please note that I have no relation with either Atmel, the producer of AVR controllers, with MCS Electronics, the maker of Bascom or indeed with any other company I mention. I have started using the AVR/Bascom combination because I felt it was one of the best combinations for hobby applications. Be aware however, that a lot of other microcontroller brands as well as software development products are available.
