About talkgroups and scan groups
A trunked radio system may consist of a many fleets of
radios, each with a number of talkgroups and scan groups.
A talkgroup consists of radio users either within the same
fleet, or across multiple fleets. A scan group is a group of
talkgroups.
When your radio belongs to a talkgroup or scan group, it is
said to be “subscribed”, and you receive all calls directed to
that group of users.
The diagram below shows a typical trunked radio system
with fleets, talkgroups and a scan group.
