Work out the Options line for your hotspot or repeater on this server.
Duplex hotspots and repeaters use both time slots. Simplex hotspots only use Time Slot 2.
Talkgroups that stay linked all the time, so you hear them without keying up first.
Paste into Configuration → DMR Configuration → DMR Options, then click Apply Changes.
Put this line in DMRGateway.ini, in the [DMR Network] section for this server.
Options can take up to 30 seconds to apply after your hotspot logs in. They last until it disconnects; after that the server defaults apply again.
