fldigi and flmsg

fldigi is a modem program for most of the digital modes used by radio amateurs today. It lets you connect your computer via sound (analog, what we can hear), over ham radio frequencies, to another computer. flmsg is a companion program to manage forms of the kind used in Incident Command Systems, by the Red Cross, and other organizations.
