Appendix A: Glossary
Frequency – The signal (expressed in MHz)
used by broadcasting radios. To nd 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 identies 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
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.
