Here are a few notes and articles about Ham Radio stuff, with the main focus on Digital Voice modes, in particular — but not exclusively — D-Star.
Check out the Terminal Mode link on the top menu. D-STAR users who want to use this feature may find it interesting. Also please check my posts listed on the right under Recent Posts.
Artwork by Philip “Gil” Gildersleeve, W1CJD. His cartoons adorned QST for many years. I encourage you to get “Gil Cartoon Collection Download“. If you can find the paper book “GIL – A Collection of Classic Cartoons from QST” I’d get that too.
