A scanner is a radio receiver that picks up frequencies that are transmitted in a certain frequency range. These frequency ranges are called bands. Take a look at your radio. Most radios are AM and FM receivers. AM is a range of frequencies to which you can tune in and listen. FM is a different range of frequencies, located higher in the frequency range, which is also used to transmit sound from radio stations. Because both AM & FM cover a range of frequencies, they are called bands. A scanner is very similar to your radio, except that your radio is limited to only AM and FM bands. A scanner can cover many bands depending upon its capabilities.
Listen. If you ever wanted to know what is going on around you, buy a scanner. You will hear police and fire departments at work, ambulances, railroad trains, and amateur radio, taxis, and weather plus government, military, marine and business services. Certain models of scanner also receive airport communications and planes in flight.
If you have ever programmed your VCR to tape a show, you most certainly will be able to program a scanner. In fact, it is probably much easier to program a scanner.
No, a License is not required to operate a scanner.
