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.
Appendix B: Search Banks
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.
