In order to set up a relay you need a .mp3 stream url. Add the relay url at the corresponding field. Make sure that you have the rights to rebroadcast any link you use. 

Then, select the start/end date of your schedule and the duration of the relay. If this is a planned relay and not a one time occasion, you can set the repetition rate accordingly to weekdays, weekends or every week. 

Owners and administrators (Staff) can schedule relays. 

In stations running under the Simulcast plan, relays are not scheduled but added via the corresponsive field under Settings>Broadcast.
