Changes to the EchoLink interface were made to avoid unintentionally interacting with the repeater controller. The change basically consist of the addition of the DTMF code “C” before every echolink command.
For example: using your DTMF keypad
– To connect to node 123456 dial: “C123456”
– To disconnect from this node dial: “C#”
