A radio scanner or simply scanner is a radio receiver that can automatically tune discrete frequencies, scanning over a frequency band to find a signal until the initial transmission ceases. The term scanner generally refers to a communications receiver that is primarily intended for monitoring VHF and UHF landmobile radio systems, as opposed to, for instance, a receiver used to monitor international shortwave transmissions, although these may be classified as scanners too.
