OpenMHz utilizes a Software Defined Radio (SDR) that is combined with a computer, and allows the recording of multiple talkgroups simultaneously, and then archives each radio message -- logging the date, times and duration of the messages. OpenMHz audio can be monitored live or can be monitored historically by listening to a specific message or playback a historical period. OpenMHz initially provides a 5-day archive of talkgroup messages.

Public safety communications is among the most valuable information that a municipality acquires. Real time and playback access is vital for safety of citizens' protection from danger, such as shootings, hazardous materials, property damage, and other life or death situations.

Cincinnati police have found that their radios aren't reliable during sudden activity or bursts of loud voices, which occur routinely in stressful situations after officers respond to scenes, according to Sgt. Dan Hils, president of Cincinnati Fraternal Order of Police Queen City Lodge No. 69. The FOP organization is considering suing Motorola to force compliance to fix the audio problems associated with the police radio system, which has also experienced dead zones where radios can't transmit or communicate even under normal voice conditions.

The problems surfaced when Cincinnati Police Department upgraded their radio system and purchased hundreds of Motorola APX 6000 radios.

All police departments in Northwest Central Dispatch System (NWCDS) in the northwest suburbs of Chicago use APX 6000 radios.
