Feature List
This page list the features of the SvxLink server and Qtel. It is a quick way to understand what the applications can be used for.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
Qtel - The Qt EchoLink Client
These are the most important features of the Qtel application.- Graphical EchoLink client application
- Use the Qt widget toolkit
- The EchoLink station list is divided into Conferences, Links, Repeaters and Stations
- A bookmark system
- Support for multiple languages (English, Swedish, German, Spanish and Italian at the moment)
- VOX
