A scanner is a radio receiver that can automatically detect or scan, two or more discrete frequencies, stopping when it finds a signal A scanner is a radio receiver that can automatically detect or scantwo or more discrete frequencies, stopping when it finds a signal on one of them, and then continuing scanning when that frequency is silent. Many scanners cover the non-band radio propagation between 30 and 951 MHz with FM, but there are models that cover most of the radio spectrum and use other modulation types. Early explorers were slow, cumbersome and expensive. Today, modern microprocessors have enabled scanners to store thousands of channels and monitor hundreds of channels per second.Newer models can monitor radio systems with shared resources and decode APCO-P25 digital transmissions. The two models of laptop and desktop are available. Scanners are often used to monitor police, fire and emergency medical services. Scanners developed from earlier tunable and fixed frequency radios that received one frequency at a time. The non-distribution systems of radio, such as those used by public safety agencies do not transmit continuously. With a fixed radius on a single frequency, much time can pass...
