Many scanners cover the non-broadcast radio bands between 30 and 951 MHz using FM, although there are models that cover more of the radio spectrum and use other modulation types. Early scanners were slow, bulky, and expensive. Today, modern microprocessors have enabled scanners to store thousands of channels and monitor hundreds of channels per second. Recent models can follow trunked radio systems and decode APCO-P25 digital transmissions. Both hand held and desktop models are available.
