Police Inaugurate Two-Way Radio
THE first two-way police radio equipment in the United States is now in operation at Piedmont, a fashionable suburb of Oakland, California. Permission for this efficient new form of communication between police officers in the field and headquarters has been granted by the federal radio commission.
The central control operates on 15 watts power and the squad cars on two watts power. The station set works directly from the electric light circuit. Power for automobile transmitting sets is secured from the storage battery.
The auto sets are compact, weighing only 25 pounds. The receiving sets are not unlike the ordinary automobile radios.
