The majority of the Minneapolis Fire and Police transmissions occur on the Minneapolis N - S sub-system (aka 1-009). This should not be confused with the Minneapolis City Center sub-system, which is for state agencies and EMS.
Upon occasion, I'll get a Minneapolis police or fire unit to come in on a Hennepin site.
When I'm up in Minneapolis, I'll have the following sites programmed in my scanner: Hennepin East, Hennepin West, Minneapolis City Center, Minneapolis N-S, Anoka, Dakota and Ramsey.
That's so I can receive the things I'm interested in: Minneapolis police, state patrol, all fire departments and Hennepin EMS. I also have the state interoperability talkgroups and all of the Tactical channels.
I seem to be hearing everything I'm interested in.
I see you are relatively new to this forum, so I'm presuming that you are fairly new to scanning. Modern scanners do have a major learning curve when it comes to programming. Complicating that is the Minnesota ARMER system. While it is a very robust system and was well thought out, it is a learning curve in its own right.
