Ohio MARCS - Multi-Agency Radio Communications

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.

Monitoring MARCS

The following scanners can be used to track the system:

• GRE: PSR-500, PSR-600
• Radio Shack: PRO-106, PRO-197, PRO-96 and PRO-2096
• Uniden: BC250D, BC785D, BC296D, BC796D, BCD396T, BCD396XT, BCD996T and BCD996XT

Unconfirmed Sites

Celina and Findlay will be coming online anytime, if they are not already. All of the other sites are questionable.

If you live in MERCER, VAN WERT, FAYETTE or TUSCARAWAS county, please monitor the sites frequencies for control channel activity.

Should be interesting if/when this site is built out..   License WQGR446 is expired,
and this particular site is not listed on any new licenses.   Furthermore, 868.2125
and 868.6125 are also part of the newer Celina license.   Given the proximity of
Celina to Van Wert, one would guess that they would not be sharing any frequencies
due to potential interference.   So be on the lookout for new frequencies for Van
Wert other than those previously listed in the old license.
