This has been the most exciting software work I've seen in the last year. David is doing fantastic work. If you haven't seen anything about the development of these tools his talk at FOSDEM in February was quite good. https:&#x2F

AG6PO here. I became licenced during my second year at university. It has actually been one of the most important parts of my professional path to this point. If you haven't yet, buy a basic hand held radio and get transmitting. The Ba
