Arlington County, Va., located across the Potomac River from Washington, D. C., placed in operation its own complete two-way radio system on June 7, 1951.
The set-up includes a headquarters radio station, mobile units and telephone switchboard.
The station is manned 24 hours a day, seven days a week, by fire department personnel.
The two-way mobile units have been installed on the first line pieces of fire apparatus in the County’s eight fire stations, plus the two chiefs’ cars, making a total of thirteen two-way mobile units.
