How do you call another station on a repeater if you know the station's call sign?

When making a directed call to a specific station on a repeater, the standard and most efficient practice is to say the target station's call sign first, followed by your own. For example, you would say 'VA3XYZ, this is VE3ABC'. There is no need to call 'CQ' on a repeater because repeaters are meant for localized, specific contacts rather than general, widespread broadcasting. Additionally, the phrase 'break, break' is strictly reserved for interrupting with emergency traffic and should never be used for routine calls.
