To access any of the available linked groups:

  • Select the channel programmed with TS1:TG9.
  • Go into your contact list, select the talkgroup (from the list below) you wish to link to and key PTT for two seconds with the desired linked group selected. When you unkey the link will be activated.
  • 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.

YSF Setup:

  1. Tune your radio to 444.750 with + offset
  2. Use DG-ID TX:00 and RX:00 (radios with old firmware should have Digital Squelch Code set to OFF)
  3. In AMS mode, set any TSQ or DCS tone/code. This prevents you from hearing the DMR bitstream which cannot be decoded by a Fusion radio and allows you to scan this channel within a list of analog and Fusion repeaters.

P25 Setup:

  • NAC: 293
  • Use talk group 3120
