A radio scanner, or police scanner because it is often called, is a receiver that can be used to monitor VHF and UHF radio systems. Almost any information transmitted by two way radio could be heard with your scanners. Most give you a feature which can be set to ignore or accept transmissions from specified departments.

In the past, scanners could only monitor a couple of different channels. Based on which you select, a portable radio scanner has become effective at monitoring a huge selection of channels between 30Mhz and 3Ghz. The VHF to UHF is between 300Mhz and 3Ghz and is used by public service agencies with their two-way radios.

Very high frequency (VHF), including 30 MHZ to 300 MHZ, is used for FM radio broadcast, television broadcast, land mobile stations for emergency purposes, military, business, amateur radio, marine communications, air traffic control communications, and air navigation systems.

Besides being found in police agencies, police scanners are also used for high frequency communication in corporations and in emergency services to help keep their information private.

Due to the rise in the amount of intrusions taking devote their communication devices the corporations started to broadcast digitally. This move opened industry for digital scanners as technology kept pace with the advances produced by the corporations.

An electronic digital radio scanner is the most recent version of popular scanners. They are made to receive and process digitally encoded signals transmitted between various two-way radio systems in public places use.

The main reason these scanners are called “digital” is basically because they are made to be appropriate for radio signals transmitted in digital mode as opposed to the conventional analog mode, although older analog signals and newer digital transmissions are generally in use. Most of the digital scanners will still process the analog signals too.

Digital signals are less suffering from interference and noise, and deliver usable information better at the extremes of these range when analog signals become unpredictable.
