SvxLink is a ham radio repeater controller and a general voice services system with features such as EchoLink and voice mail. The biggest news in this release are: improved logic linking, improved QSO recorder, support for squelch on GPIO, improved pre- and deemphasis filters. More details about each change can be found in the ChengeLog below.
The SvxLink project can be used as a replacement (and more) for the Windows only closed source EchoLink application. To get started, have a look at the SvxLink homepage: http://svxlink.sourceforge.net/
