EchoLink allows licensed Amateur Radio stations to connect to one another over the Internet.  You can use EchoLink to connect your station (or your computer) over the Internet to other amateurs using the same software, and carry on a voice QSO.  This greatly enhances the range and utility of mobile and portable VHF/UHF-FM stations, and also allows computer-equipped hams to access distant repeaters directly.

You can access EchoLink either with a radio or a computer.  If you are in range of an FM repeater or simplex station equipped with EchoLink, you can use DTMF commands from your radio to access the EchoLink network.  If you are a licensed amateur with an Internet-connected PC, you can access EchoLink stations directly from your PC.
