The SvxLink Server

These are the most important features of the SvxLink server application.

• Can act as a repeater controller or just operate on a simplex channel
• Plugin based system to load voice services into the SvxLink logic core
• DTMF controlled
• DTMF anti-flutter mode to suppress multiple digit detection when mobile flutter is present or during weak-signal conditions
• A sound clip based system for announcements
• Periodic identification
• A script based (TCL) event handling system
• Possible to use left/right stereo channels as two mono channels
• Roger beep
• Trigger manual identification by pressing DTMF *
• A simple shortcut, or macro, subsystem
• Repeater logic specific features:
• Multiple repeater activation modes: 1750 Hz tone burst, CTCSS, DTMF or squelch open.
• Periodic "idle sound" when the repeater is up but no signal is being received
• Announcements are mixed in with normal audio
• The volume of announcements is lowered if there are other traffic
• Possible to define multiple logic cores to connect to multiple transceivers
• Possible to link logic cores together
• Support for multiple receivers using a software voter
• Remote receivers can be linked to the logic core via TCP/IP(Internet)
• Remote transmitters can be linked to the logic core via TCP/IP (Internet)
• Multiple squelch detectors: Vox, CTCSS, signal level and external (through serial port pin)
• Digital deemphasis/preemphasis filter
• DTMF muting
• Squelch tail elimination
• CTCSS transmit, always or just when the squelch is open
• A simple help system module
• A parrot module that retransmit received audio
• An EchoLink module used to connect to other EchoLink nodes
• Idle timeout
• A callsign lookup/connect by callsign function
• List connected stations on demand
• Own node id report function
• Random connect to link, repeater or conference
• Reconnect to last disconnected node
• Listen only mode
• APRS node info announcement support
• A voice mail module
• Record voice mail for local users
• A DTMF repeater module that retransmits received DTMF digits.
• Control other DTMF controlled stations on the same frequency
• Possible to write new modules in the TCL scripting language
