[Rich83]

Has anyone figured out any specific talk groups on this system? I have a few that I have some idea of but cant pin point who's using what.

211-1 - plumbers ?
57520 - snow ploughs ?
212-1 - Ambulances or patient transfer service ?

211-1 Roto Rooter
212-1 and 212-2 Lifeline ambulance
57520 Des Moines Waterworks
And one more notable TG 403-7 NPI Security
