Bonus Facts: A Brief History of Police Radio Communication

Long before modern voice radio systems, APCO first proposed brevity codes based on Morse code in 1935. These were inspired by procedures used by the U.S. Navy and were initially developed for Morse, not voice transmission. Over time, this system evolved to meet the needs of voice communication in policing, leading to the standardized 10-codes we use today—such as the 10-45b police code.

The 10-45b police code is just one part of a larger, well-organized framework of communication designed to streamline emergency response and improve public safety. You can hear this and many other codes in action by using a police scanner or tuning into local emergency frequencies.
