Beyond the Basics
too high, it could prevent your scanner from locking on the
control channel reliably. If it is set too low, it will slightly delay
fi nding the control channel. The best setting is the same
as for conventional reception and is critical for monitoring
trunked systems.
programming trunking frequencies
There are three steps for programming a trunked system:
1. Program the Trunk Type - enter the type of trunking
system the scanner will track -- Motorola Type II, Type I,
EDACS, LTR, etc.
2. Program the trunked frequencies - within a trunked
system, the frequencies are shared among all users.
These frequency groups are called talk groups.
3. Program the Talk Groups - Within a trunked system, each
agency or department is assigned a talk group ID. This ID
must be programmed into the scanner in order for it to
monitor that specifi c agency or department.
Before you start programming your scanner to track a
trunked system, consider the following:
• You can only program one type of trunking system in
each bank of your scanner.
• Trunked frequencies must be entered while in the trunk
programming mode.
• If you're in the trunk programming mode, you cannot
select channels in other banks. For example, if you are
programming Bank 4, you can only select channels 301-
400 by pressing
If you are programming an EDACS trunked system, you

must enter the frequencies in a specifi c order. Check
