The State Troopers Association of Nebraska pulled its grievance after problems with the service became public and state officials moved to address them.
Brian Petersen, president of the association and the State Law Enforcement Bargaining Council, says members still have concerns about radio communications in an emergency.
The system is used by the Nebraska State Patrol, the State Fire Marshal’s office, the Game and Parks Commission and other agencies. It failed during a June 2012 police standoff in Alliance, forcing Nebraska troopers to use personal cellphones to communicate.
Brenda Decker, the state’s chief information officer, says officials have made upgrades intended to help law enforcement.
