Creating Scannable Objects
on a trunked radio system. A TGRP object
allows you to scan and monitor a talkgroup on a
particular trunked radio system.

Essential Parameters

As a standalone object, a TRGP object is similar
to a CONV object. However, for trunking to work,
the trunking system (TSYS) and the talkgroup ID
must be specified. We also recommend that you
label your TGRP object by giving it a name in
the TAG field, making it easier to find the TGRP
object later, and identifying it when the scanner
stops to monitor activity.

Trunking System (TSYS) Objects

The first time you make a TGRP for a particular
trunked radio system, you must also create a
TSYS object that contains the system parameters
associated with that trunked radio system. Once
you create a TSYS, you can use it over and over
again without having to re-enter all of the system
data.
A TSYS object has its own set of essential
parameters, and these parameters vary
depending on the type of trunked radio system
you plan to monitor. If you are a reasonably
experienced user, you probably already know
what the essential parameters are for the
system you wish to monitor. For example, each
TSYS must correctly specify the type of system
being monitored, the control channel or LCN
frequencies used by the system, and so on. A
detailed description of each type of system
supported by this radio and the essential
parameters required to make them work properly
is provided in "Appendix B: Detailed Menu Reference:
TSYS Menu" on page 113.
