63PSFIRE1 is public safety fire... Oak Park, Huntington Woods, Berkley, Beverly Hills, ect all use that talkgroup for fire dispatch.
Likely wont hear anything on 63F911, 63P911, or 63F911. Those are central dispatch talkgroups that MPSCS created for every county in the state when they first designed the system layout. Since Oakland County really dont have a countywide fire or ems system, those are of no use. the P911 is typically used by the county sheriff. Oakland county Sheriff uses their own talkgroup layout.
You MAY hear something on 63COM... maybe an agency from a neighbor county trying to call someone in Oakland. Again, wont likely hear any interdepartmental radio traffic from one Oakland County agency to another because they have an "All Dispatch" talkgroup for that purpose.
The MSP talkgroups were created as a inter-system patch talkgroup between MSP on MPSCS and Oakland County on their Open Sky system. Those are no longer of any use that I am aware of.
