About

The Ohio Multi-Agency Radio Communications System (MARCS) is a Motorola Type II SmartZone/Omnilink system with 100% digital audio.

Most state agencies use this system to some extent, with agencies like the Highway Patrol, Department of Natural Resources, Emergency Management and other emergency services using the system almost exclusively.

Various local agencies also use the system; please check the database for a complete listing of talkgroups.
