A new fresh version of SvxLink, 080518, has now been released.
The biggest change is internal. Big parts of the audio handling subsystem has
been rewritten. This has made it possible to implement a couple of new
features and it will be easier to implement new features in the future.
Qtel does not change very often but this time I got a patch from Stuart
Longland which adds VOX functionality. At the moment it only works if full
duplex is enabled under the sound card settings tab.
Some of the most important changes in the SvxLink Server are:
* Implemented remote TX. The new application "remotetrx" now handle
both remote transmitters and receivers. The old application "remoterx"
has been removed.
* Now possible to use left/right stereo channels as two mono channels.
Which channel to use is chosen by the new configuration variable
AUDIO_CHANNEL that must be set for RX and TX configuration sections.
* Added a signal level based squelch type. Set SQL_DET to SIGLEV to
use the new squelch type. Configuration variables SIGLEV_OPEN_THRESH
and SIGLEV_CLOSE_THRESH will control at which levels the squelch will
open and close. To use this squelch type, the signal level detector
must have been calibrated by setting up SIGLEV_SLOPE and SIGLEV_OFFSET.
Also, since the detector is not perfect you probably need to set
SQL_HANGTIME to a couple of hundred milliseconds. If using a voter,
SQL_DELAY might have to be setup to get reliable signal level readings.
A value of 40 seem to work fine.
* Macros behave a little bit different now. The macro digits are now sent
back into the logic core, digit by digit, as though they were received
from the DTMF decoder. This mean that all macro commands have to be
ended with a number sign to be executed.
Make sure you read the ChangeLog (really) for all the details.
Enjoy the new release!
