A group of amateur radio operators who share email on a specific amateur radio topic
An identifier used by DMR to organize radio traffic so that those who want to hear the group aren’t bothered by other radio traffic✓Bonne réponse
The members of a net organized for amateur radio operators with a specific common interest
A method of automatically alerting all group members to the frequency where any member is transmitting
Explication
On DMR a talkgroup is a numeric identifier that sorts traffic, so listeners only hear the conversations they have selected. It is a technical routing label, not a club, a net or an email list.
