Understanding talkgroups
This feature is available for digital channels only.
A talkgroup is a collection of radio users with whom
you want to have private conversations. For example,
a state's public safety agencies could have the
following talkgroups:
■
Local talkgroups—used by a specific agency to
communicate within their own local agency. It may
even be made up of a county of public safety offi-
cers.
■
Regional talkgroups—used by large state agen-
cies that have regional divisions.
■
Statewide talkgroups—used by an agency to com-
municate with a public safety member in another
region. Statewide talkgroups, as their name sug-
gests, enable public safety agencies to communi-
cate with each other from one end of the state to
the other.
■
Special event talkgroups—may be used to man-
age emergencies encompassing a large area, or
even events such as visits by heads of state.
