Talk and Listen Groups Explained

scans active voice calls. You can change the way your radio scans for active
voice calls.
Talk group A talk group is the primary user group in a profile. This is the group of users
you will talk with and listen to the most. The first user group in each profile is
your talk group.

normally hear the voice calls from the users in this group, but your voice does
not transmit to them.
