In west-central Ohio: Post 6 (Wapakoneta), Post 12 (Springfield), Post 29 (Xenia), Post 55 (Piqua), Post 57 (Dayton) and Post 80 (Marysville).

This feed provides the dispatch communications for Ohio State Highway Patrol (OSHP) District 5, which is 5,339 square miles in size and includes the west-central Ohio counties of Auglaize, Champaign, Clark, Darke, Greene, Logan, Mercer, Miami, Montgomery, Preble, Shelby and Union.

District 5 utilizes the statewide Ohio MARCS-IP System, a P25 Phase 1 system which is APCO-25 Common Air Interface exclusive.

Voices sometimes sound somewhat "robotic" when a digital system such as MARCS-IP is monitored by a consumer grade scanning receiver. Further, constraints inherent in the scanner firmware and/or  simulcast digital distortion may sometimes cause voices to be markedly distorted, broken and/or garbled.

In the absence of an incident directly affecting life and/or property, it is not unusual for little or no communications to be heard for extended periods of time. OSHP broadcasts, due in part to their traffic enforcement emphasis, tend to be brief and more concise in comparison to that of the local county sheriff and city police, fire and emergency agencies.

The feed origin latency (the time elapsed between when the scanner audio is heard at the feed location and when that same audio is heard via the feed) is typically about 60 to 70 seconds.
