The UrCall field in your D-Star transceiver is eight characters long and the last (8th) character is used for the actual command.

When sending commands that require a repeater or reflector to be specified, the first six characters are used to indicate the repeater/reflector callsign, e.g. “REF003″, the 7th character indicates the module, e.g. “C”, and the 8th character is the command, e.g. “L” for link.

If the command doesn’t require a repeater or reflector to be specified then the first seven characters are spaces (blank).

VK7RRR will respond to the following commands in the UrCall field:

Note: The “▪” character represents a space. So in all cases below the last (8th) character is the command.

XXNYYYML - Link to repeater/reflector (see below)
▪▪▪▪▪▪▪U - Unlink from repeater/reflector
▪▪▪▪▪▪▪I - Status
▪▪▪▪▪▪▪E - Echo test

The Link Command

  • XXNYYY is a gateway (repeater/reflector), M is the gateway’s module and L is the LINK command.
  • The XXNYYY portion of the link command can be a repeater or a D-Plus (REFxxx), DExtra (XRFxxx) or x-Net (DCSxxx) reflector.
  • Remember to set UrCall to “CQCQCQ” once a link has been established otherwise audio will not be routed to the remote repeater/reflector.

Examples:

To link VK7RRR to Reflector 3 Module C

(The Australian D-Plus reflector module C)

Set the UrCall field of your D-Star transceiver to "REF003CL" and press the PTT button. If successfully received the repeater will respond with a “Linked to” message.

To link VK7RRR to DCS Reflector 2 Module J

(The Australian module on the international DCS reflector)

Set the UrCall field of your D-Star transceiver to "DCS003CJ" and press the PTT button. If successfully received the repeater will respond with a “Linked to” message.

To unlink VK7RRR from Reflector 3 module C:

Set the UrCall field of your D-Star transceiver to "▪▪▪▪▪▪▪U" and press the PTT button. If successfully received the repeater will respond with an “Unlinked” message.

To hear the current link status of VK7RRR:

Set the UrCall field of your D-Star transceiver to "▪▪▪▪▪▪▪I" and press the PTT button. If successfully received the repeater will respond with the current link status, either “Unlinked” or a “Linked to” message for the repeater/reflector to which it is currently linked.
