Just as with analog repeaters, D-STAR repeaters can be “linked” to permit QSOs among all users of linked gateways. "Reflectors" are special gateway computers that provide a way to dynamically link multiple gateways together for nets, emergency operations, etc.
ACCESS
To link to a reflector, program URCALL with the Reflector callsign / Module / Link. For example, REF012AL for Reflector 12, Module A. Carry out your QSO on your "Gateway QSO" memory, and unlink by keying up on your "Unlink" memory.
