CE0Y/DJ4EL: trigger callsign category will not accept the stroke character and will not alert for either the CE0Y or DJ4EL callsign separately. How should I set up the trigger for this callsign?

Just use DJ4EL as callsign trigger.

Alternatively, if you only want it to match CE0Y/DJ4EL (and not, for example, when DJ4EL operates at home or in another country), you can simply use a “Full callsign” condition.

Thank you for your very helpful suggestion. Using only the prefix “CE0” also works, because the prefix is unique to Easter Island.
