  2. Linking and Routing • Call Sign Routing vs Linking • What are these features? How do they work? • When do you use them? • Issues • Radio programming

  3. Call Sign Routing • Early feature of D-STAR Network – before linking was available • Allows you to contact a station anywhere on the network without knowing where they are • Routing will be to the last repeater where the destination station has transmitted on • Some issues related to call routing to keep in mind.

  4. Issues – Call Sign Routing • Destination station must have recently transmitted • Call sign updates may take a while – so if the destination station has changed repeaters the system may not find the call in the right spot! • Destination station must “call capture” • Not possible to know if the destination repeater is in use – you could come in right on top of a QSO in progress • You will not hear any users on the destination repeater except those that “call capture” you • Must return UR to CQCQCQ when done!

  5. Linking • Generally preferred usage • Can link to a repeater (any module) or a reflector • Ability to monitor the destination without interference • Call capture not required at destination • Anyone on frequency will be heard

  6. Issues - Linking • You need to know which repeater (and module) the destination station is monitoring (if you are looking for a specific station) • Once you successfully link – you must return your UR to CQCQCQ! • The same when you issue the unlink command

  7. Radio Programming 1 • Call Sign Routing: • UR: The destination callsign • RPT1: The local repeater (i.e. VA3ODG B) • RPT2: The local gateway (i.e. VA3ODG G) • IMPORTANT: Return UR to CQCQCQ when done!

  8. Radio Programming 2 • Linking (Repeater/Reflector): • UR: The destination repeater/module followed by L in the 8th space (i.e. VE3YYZBL or REF016CL) • RPT1: The local repeater (i.e. VA3ODG B) • RPT2: The local gateway (i.e. VA3ODG G) • If successful you will see a message returned from destination repeater i.e. Connected to VE3YYZ B

  9. Radio Programming 3 • Linking (Repeater/Reflector):Once the link is established, remember to change the UR to CQCQCQ! • To unlink change the UR to the following: • -------U (7 spaces then U) • After successful unlink message received remember to change the UR back to CQCQCQ
