The SvxLink server provides access to a ham radio transceiver via the EchoLink® protocol. It can act as a repeater controller or operate on a simplex channel. Based on a modular design, the server can be configured to provide voice mail and echo (talkback) service. It is normally used together with the 'remotetrx' package, which allows the remote control of a radio transceiver.

For a client program implementing the EchoLink® protocol, please have a look at the 'qtel' package.

EchoLink® allows licensed amateur radio operators to communicate over the Internet, including remote access to station equipment. EchoLink® is a registered trademark of Synergenics, LLC.
