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.
