DSTAR Reflectors and Links:

Reflectors are like phone conference bridges. They allow more than one DSTAR repeaters to link together and allow all linked repeaters to hear the person talking.

You can also link two DSTAR repeaters together, and disconnect them at your leisure. When you link the repeaters and make a call with UR=CQCQCQ, RPT1=W4HPT B and RPT2=W4HPT G, persons on both repeaters can hear your conversation.
