Radar
Hello, I'm Pierre cb. I wanted to let you know that I undid one or more of your recent contributions because it did not appear constructive. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks!

Please refrain from German centered edits. Radar is not a German invention, it is a collective aggregation of experiments where Germans, like Christian Hülsmeyer, added their contribution.
