MARCS, or Multi Agency Radio Communications System, is the State of Ohio's Motorola Digital 800 MHz trunking network, providing statewide voice and data communication for numerous state, county, and local government agencies.

The MARCS database is constantly growing and changing. We are providing a link to the Radio Reference website. Radio Reference maintains an awesome national scanner database with numerous authors and "checkers" who collect and verify the constantly changing information on large statewide systems like Ohio MARCS. You need to join (i.e. "pay") Radio Reference to use some of their top end features, but basic information is available for free.
