Various departments are able to communicate without going through a dispatch link.
The system also includes service to local hospitals, the Dubuque Regional Airport and the Dubuque County Conservation Board's park system. In early 1992, county public safety agencies became aware that expansion of its radio communication system was not possible because of a lack of availability of high-band radio frequencies. The agencies and the service board decided to research a move toward the 800-megahertz frequency band. This system has tons of additional things that makes our job a lot easier. Leonard J. Koehnen, of Woodbury, Minn., was hired in October 1995 as the project's engineering consultant.
