OHDEN Standard Operating Guide (SOG)


In times when the normal communication channels are compromised or overloaded, the local agencies that ARES serves rely on having an alternate and reliable means of communication to other counties as well as to state-level Ohio Emergency Management. OHDEN was created as a system of amateur radio operators and equipment to perform this function.

OHDEN uses the amateur radio digital modes to transfer messages using the standard forms used in the Incident Command System, the standard of all emergency management agencies. The forms and the software that interfaces with the radio are part a suite of software known as Narrow Band Emergency Messaging Software (NBEMS) which is free to download and requires a minimal of additional hardware. OHDEN relies on Near Vertical Incident Skywave (NVIS) propagation to allow for communication of up to several hundred miles for reliable messaging within the state.

It is our goal to have this capability within each of the 88 Ohio counties’ served agencies along with trained amateur radio operators to provide it.
