SvxLink

This is a bugfix release for the 11.11 version released earlier. Two serious bugs have been fixed, one which caused RemoteTrx to crash on disconnections and another which could cause a transmitter to hang in certain setups.

The main focus in this release was to get the Qt code (e.g. Qtel) moved from using Qt version 3 to Qt version 4. Note that the Qtel config will be lost when installing the new version. A number of bugs have been fixed, both in Qtel and SvxLink, and smaller additions to existing features have been made.

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.

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.

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.
