Alright, you believed ‘cops’ that isn’t a word we normally use here within the United kingdom. We Brits historically tend to refer, courteously, to our ‘boys in blue’ as ‘bobbies’ or ‘the old bill’.
Anyway, given that, I’m about to assume that you’re wondering about the United states police and their longstanding joint venture with the Motorola Corporation. OK, here goes…
Reported by Motorola’s own web site,
“Law enforcement communications and police communications are essential assets to the safety and security initiatives in any community. Advancing police communications allow law enforcement to be more mobile and more rapidly respond to issues. Motorola offers an extensive product line to enhance law enforcement communications with less paperwork and faster, highly reliable performance”.
Motorola manufactured car radios as early as the 1920’s and United states police and the fire brigade used several of those, however it wasn’t until 1930 that the first police force car radio was made and constructed by Motorola. In line with the official website,
“Sales of Motorola police radios began in November 1930. Among the first customers (all in the U.S. state of Illinois) were the Village of River Forest; Village of Bellwood Police Department; City of Evanston Police; Illinois State Highway Police; and Cook County Police in the Chicago area. As more police departments used radios, challenges emerged. Rough roads, engine noises, interference, high power consumption, and frequency instability led Paul Galvin to recognize that police departments needed a radio specifically engineered for patrol cars”.
In 1936, the Motorola Police Cruiser Radio was built. It had been a hit and Motorola have been a trusted brand by US Police ever since. In 1939, engineer Don Mitchell fashioned the Mobile T6920 AM Transmitter. It had been another accomplishment, becoming a rational choice for that police force as,
“This complete Motorola two-way radio system was priced about one-fourth as much as the competition’s, and the transmitters could be installed in cars that already had receivers in the same frequency band. In 1940 the Police Department in Bowling Green, Kentucky, became the first customer for a complete Motorola AM two-way radio system. The radios were so well-designed that Galvin Manufacturing produced the same models for several years, until FM technology replaced them in the 1940s”.
Evidently, the US police force use a long and fruitful relationship with the Motorola Corporation. This noticeably applies to walkie-talkies too. It makes good sense to use a trusted, easy to use brand for successive generations of officers, who often have to respond swiftly and instinctively to numerous troubles.
The initial police to utilize 2 way radios were in fact Australian, but subsequently the Second World War, mobile two way radios grew to be standard issue in the majority 1st world states.
