GM4SLV Allstar
I'm working on this project again….
You can see an overview and the Allmon/Supermon dashboards at http://gm4slv.plus.com:42111/
I'll start a new active wiki page for it under 2025 Radio Topics soon

Courtesy Tones
Can give information about the node status.
After a local Transmission on the “input” frequency the reponse will be one of:
- Morse Letter I (di-dit) = node is not connected to any other nodes
- Morse Letter R (di-dah-dit) = node is connected in “Monitor/RX only” mode to one or more nodes
- Morse Letter K (dah-di-dah) = node is connected in “Transceive” mode to one or more nodes
There are other tones, e.g. when a station on a linked node unkeys there's a low-pitched “bloop”
When a local RF station sends a command there's a “bip bip” (not to be confused with the Morse letter I)
Echolink
AllStar nodes can also connect to Echolink
The node is occasionally connected to Echolink as GM4SLV-L
(UPDATE — John Pumford-Green 24/04/23 14:47 )
I have disabled the Echolink connection by editing
/etc/asterisk/modules.conf to change the channel driver for Echolink to noload →
To turn Echolink ON or OFF edit /etc/asterisk/modules.conf
OFF
noload => chan_echolink.so ;
ON
load => chan_echolink.so ;
an Asterisk reload is necessary:
gm4slv@mb7aze:/etc/asterisk$ sudo astres.sh Restarting Asterisk systemctl restart asterisk.service
