Appendix A: Glossary

Frequency – The signal (expressed in MHz) used by broadcasting radios. To find active frequencies, you can use frequency guides available from your local RadioShack store, frequency lists posted on the Internet, or your scanner’s search function.

Bank – A storage unit for a group of channels. A channel contains one frequency, and a bank can hold up to 100 channels.

Channel – A programmable memory locations for a single frequency.

Talk Group ID – A simultaneous trunking transmission that identifies 2-way radio users. This allows trunking systems to allocate a few frequencies to multiple 2-way radio users.

Sub-bank– Each bank has an associated Talk Group ID sub-bank. In Closed mode, the scanner only stops if a transmission has a Talk Group ID saved in the associated Talk Group ID sub-bank. In Open Mode, the scanner stops on all transmissions, except those you lock out.

Note: All scanners tune by steps. Your RadioShack scanner uses steps consistent with the latest US or worldwide standards. If you enter a non-valid step frequency, any scanner will tune to the next step.

Some scanner designs do this without showing the correct step in the display. This scanner will show the actual tuned frequency in the display. Because steps are so close together, the audio quality will not be affected by the offset.
