OPD Upgrading Radios to Digital
OPD Upgrading Radios to Digital

Owensboro police officers will begin training next week on the department’s new digital radio system, and once everyone is trained, officers will switch to the system later this month.
OPD and agencies such as the Daviess County Sheriff’s Department and area fire departments currently use analog radio systems. Paul Nave, director of Owensboro and Daviess County’s combined 911 dispatch center, said digital radios will provide a much clearer signal than analog.
Nave said radio signals from areas outside Daviess County can sometimes be heard on the analog radios.
“With digital (radio), it’s computer generated,” Nave said. “It’s very precise and clear versus analog. With analog, you had the potential of receiving signals that can bounce off the atmosphere and can interfere with your communication.”
The switch required dispatch to install new infrastructure at the dispatch center. Many of the department’s existing radios are capable of being upgraded to receive digital signals, Nave said.
Dane Galloway, the city’s finance manager, said the change is part of making the community “Project 25” compliant. The federal government wants communities to be “P25 compliant,” by switching to digital voice communications that communities can use to communicate with one another during disasters when other forms of communication, such as cellphones, are not operating.
“Some of our radios can be converted to P25 and some are obsolete and cannot be converted to P25,” Galloway said. When communities are P25 compliant, “we can communicate across the Tri-State, to make sure each agency has the response they need” during a disaster.
The city spent $700,000 to upgrade the 911 center’s transmission tower, for hardware for the digital radio system and to purchase 70 radios that could not be upgraded to digital, Galloway said. The city purchased software for the digital system and to upgrade the radios that could be adapted to digital for about $580,000.
Nave said federal agencies that have radios capable of being programmed with local digital channels will be able to communicate with OPD during emergencies. The long-range goal is to convert all law enforcement and emergency response agencies to digital radios, he said. Nave said there won’t be a noticeable delay in the digital radios, but the officers will be trained so they can get accustomed to the differences between the analog and digital signal.
“The officers will hear a different quality of voice,” Nave said. “They’ll have to tune their ears to the change.”
