Make a note of the displayed frequency or store it at that time, then continue the search. Pit crews and drivers may use different transmit frequencies. The instruction manual that comes with a scanner typically shows what frequency bands are for government, business, aviation, and other users. If the search function stops on a frequency, you can find who is assigned to that frequency . If you listen to airports, aviation and flight tracking information is available.
More expensive models have even more.
The user can typically enable or disable certain banks of frequencies for scanning. Each bank can hold 10-30 frequencies, depending on the brand and model of the radio scanner. Often, banks contain frequencies according to the type of radio service. Types include emergency, police, fire, aviation, marine, and business. This delay helps the user hear the other part of the radio conversation on the same frequency by momentarily keeping the scanner stopped.
