Scanning

The term scanner generally refers to a communications receiver that is primarily intended for monitoring VHF and UHF land-mobile radio systems, as opposed to, for instance, a receiver used to monitor international shortwave transmissions. Scanners are often used to monitor police, fire, and emergency medical services. Radio scanning serves an important role in the fields of journalism and crime investigation, as well as a hobby for many people around the world.
