SvxLink
SvxLink is a flexible general purpose voice services system for ham radio use. It can act as a repeater controller or operate on a simplex channel. The server consists of a core that handles the connection to the transceiver. The transceiver audio is connected to the PC through the sound card, and the PTT is controlled by a pin in the serial port. The voice services are loaded into the core as modules. Examples of existing voice services are a help system, a module that plays back everything you say, a module to connect to other EchoLink stations, and a voice mail module. The project also includes an EchoLink client GUI application (Qtel).

Recent releases
- 28 Apr 2009 20:09
Changes: The server has a new DTMF decoder and a new tone detector. The SpanDSP library is no longer required. The RemoteTrx protocol has been improved with audio compression and authentication. The EchoLink module is now able to register itself on the EchoLink "link status" page. APRS functionality has been added so that position and other useful info can be sent to the APRS network. Qtel has three new translations: German, Spanish, and Italian. A number of bugs have been fixed.

Changes: This is mainly a bugfix release. The previous release was very unreliable and had a number of flaws that are now fixed. If you are running the 080518 release, you should upgrade.

Changes: The most important change in this release is internal. Most of the audio handling code in SvxLink has been rewritten. This has made it possible to implement a couple of new features and will make it easier to implement audio related features in the future. Other changes include a remote transmitter via TCP/IP, usage of left/right stereo channels as two mono channels, a signal level based squelch type, and a number of bugfixes.

Changes: The biggest change in this release is that a third-party DTMF decoder is now used in the SvxLink server software. This is a much better implementation than the one used previsously. Other than that, it's mostly bugfixes and compatibility changes.

Changes: Support for remote receivers linked over the Internet has been added. To be able to use multiple receivers, a simple signal strength detector was implemented. CTCSS tone transmit has been implemented and the CTCSS squelch detector has been improved, which makes it possible to run SvxLink with the squelch open. DTMF muting and squelch tail elimination has been added, and there are a couple of other changes and bugfixes.
