The Interagency talkgroup is primarily used for communication between FD and EMS or PD and EMS.
The events channels are in every PD and FD radio. (maybe more?)
The 911 Emergency talkgroup is in every city radio, as well as WRTA buses. It is monitored by a Fire Department dispatcher. It usually is used by DPW workers or WRTA drivers to report MVAs or medical emergencies. During a recent disaster drill it was used for communication between the dispatcher and incident commander.

Public Works Talkgroups

  • All public works talkgroups are TDMA (Phase II).

Note there are numerous Talk Groups listed on other sites, most are inactive. It would take up too much space to list them all on this page. A lot of these TGs use informal communications (e.g. "Hey Bob!") and at the most refer to a "base" as dispatch (e.g. "Water Base"). Some of these TGs. have very brief communications and extreme bouts of inactivity. This is mainly due to the nature of their jobs not needing radio communications as much as public safety agencies, and the proliferation of cell phones for use by smaller city agencies.
