Scanning
Wildcard Talkgroup Notes:
Wildcard is a special type of TGRP object that allows you to
monitor all talkgroup call traffic on the associated trunked radio
system.
Wildcard TGRP objects allow you to quickly find and store new
or unknown talkgroups on a trunked radio system.
When a Wildcard TGRP object is mapped to an active Scan List
and scanned, all talkgroup traffic on the system is monitored,
and you have the option to save or lock out new talkgroups as
they appear.
Wildcard objects are easier to find and change later if you
include an abbreviated name for the system in the tag field.
TGRP objects are also used to receive Private/Individual Calls on
trunking systems that support these call types.
Duplicate (DUPE)
Duplicate (DUPE) is useful when entering multiple TGRP objects that
are hosted on the same trunked radio system, or multiple CONV
objects that have similar parameters or tag names.
1. Press PROG.
2. Press p or q to scroll to the object that you wish to duplicate.
3. Press the EDIT softkey, then press the DUPE softkey.
An exact copy of the object you selected is created, and the
scanner displays the newly created object menu so you can
change the parameters that need to be changed. Be sure to
change the tag name before saving your new object.
4. Press the SAVE softkey to save the new object.
Note: As soon as you press DUPE, a duplicate of the selected object is
created and saved in memory. Be sure to delete any objects that you
create accidentally. See “Deleting Objects” on page 44.
Basic Scanning Operation
Before the scanner can begin to scan, you must have created
scannable objects. Your scanner will scan any scannable objects that
are members of enabled Scan Lists and are not locked out.
1. Press SCAN to start scanning.
Scan lists 1 to 10

Press SCAN or PAUSE to resume scan.
Wildcard Scanning
A Wildcard TGRP object allows you to receive all radio traffic on
a trunked radio system. It works by catching talkgroup calls on the
system that are not already stored as objects in the radio’s memory.
In order for the Wildcard TGRP to function properly, the radio needs
to be in SCAN Mode. This is what enables the scanner to find the
previously stored TGRP objects that need to be checked before
declaring that the found talkgroup is new and should be scanned as
a Wildcard “hit.”
If you park on a Wildcard TGRP object in Manual Mode, the scanner
is not able to “see” the previously stored TGRP objects, and every
call on the trunked radio system will come up as a wildcard hit.
