Howdy and Welcome!

Because content of my site grew more and more, I have re-organized and re-designed this website. To make orientation easier, underneath a tree-view based display of the content of my website can be used to find topics and navigate. Should you have any questions, comments or you would like to buy a radio kit, components or other material, please mail

Please keep in mind that the designs are free for non-commercial use and for educational purposes. Any commercial exploitation would violate this copyright. Thank you!
