[$] FOSS for amateur radio

Amateur ("ham") radio operators have been experimenting with ways to usecomputers in their hobby since PCs became widely available-perhaps evenbefore then. While manypeople picture hams either talking into a microphone or tapping a telegraphkey, many hams now type on a keyboard or even click buttons on a computer screen to makecontacts. Even hams who still prefer to talk or use Morse code may stilluse computers for some things, such as logging contacts or predictingradio conditions. While most hams use Windows, there is no shortage of hamradio software for Linux.
