The state of Minnesota has been slowly rolling out a statewide 800-MHz digital APCO-25 trunked system that can be used by local and state public safety agencies. Systems are currently installed in the Twin Cities, the St. Cloud and Rochester areas. While many areas remain on VHF and UHF analog systems, a digital trunking scanner is needed to monitor the state's ARMER radio system.
The best choice for a police and fire scanner for Minnesota -- especially in the Twin Cities, St. Cloud and Rochester areas -- would be a digital trunking scanner.
