Amateur Radio Software from K1RFD

EchoLink

EchoLink is software which allows Amateur Radio stations to communicate with one another over the Internet, using voice-over-IP (VoIP) technology.  The program allows worldwide connections to be made between stations, from computer to station, or from computer to computer.

EchoStation is a repeater-control program for Windows which makes it easy to set up a complete, fully-functional repeater or "announcement machine" using a personal computer.
