A digital radio scanner is a radio receiver that monitors non-broadcast radio signals. It's used to listen in on signals like those transmitted from civilians, marine and boating communications, air traffic control, police, fire, and EMS. They are used by journalists, crime investigators, and hobbyists who just like to listen in and hear what's going on around them.
Digital scanners are not illegal in the United States and have been used all around the country for decades. However, depending on where you are, how you use a scanner may make that use illegal. For instance, much like cell phones, many states have restrictions against using scanners while driving. There are also various laws around the country that make it illegal to use a scanner during the commission of another crime. There may be other laws in your area, so be sure to check all local and state regulations before using a scanner.
Analog scanners were the first models, and are still in use today. They pick up non-digital radio transmissions, used in many small cities and rural areas. Analog trunked radios allow several users to share the same frequencies or pool of frequencies. Digital scanner systems have clearer sound and a larger range of reception and can allow encrypted channels so unauthorized users may not be able to listen in. Digital scanners can pick up all 3: analog, trunked, and digital transmissions.
