To access any of the available linked groups:

  • Select the channel programmed with TS1:TG9.

  • When your radio display reverts back to S1:G9 you may begin talking.
    • Note: The linked group ID’s are to be used for in-band signalling to trigger link activation, not to talk on. All voice traffic for linked groups happens on TS1:TG9.
  • Please don’t do this to “lurk” on a group.
  • Linked groups remain active for 30 minutes after the last local transmission, and only one linked group is available at a time.
  • Please do not transmit voice on any TGID not listed above.

Here is a video that demonstrates contact-based linking.
