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)

AllStar nodes can also connect to Echolink

The node is occasionally connected to Echolink as GM4SLV-L

(UPDATEJohn 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


noload => chan_echolink.so ;


load => chan_echolink.so ;

an Asterisk reload is necessary:

gm4slv@mb7aze:/etc/asterisk$ sudo astres.sh
Restarting Asterisk
systemctl restart asterisk.service
