common scanner terms

To find a station, you must tune to a FREQUENCY (expressed in kHz or MHz). To find active frequencies, use the search function or purchase a frequency reference.

In addition to searching a selected frequency range, you can also search your scanner’s service banks. A SERVICE BANK is a preset groups of frequencies categorized by the type of services that use those frequencies. Your scanner comes preprogrammed with all the frequencies allocated to the weather, marine, aircraft, rail road, CB, news, and police/fire/ emergency services.

When you search and find a desired frequency, you can store it into a PROGRAMMABLE MEMORY LOCATION called a CHANNEL. Channels are grouped into channel-storage banks called a private bank. Your scanner has 10 CHANNEL STORAGE BANKS and each bank has 100 channels. You can scan the channel-storage banks to see if there is activity on the frequencies stored in them.
