assigned in the individual object menus. For now, just let your new
objects go to the default Scan List 01. Later in this section we will
show you how you can group your objects into Scan Lists.
Talkgroup Object (TGRP)
A Trunking Talkgroup Object (TGRP) is a record that stores the
parameters for a trunked talkgroup on a trunked radio system.
When you create a TGRP object, you are creating an object that
will allow you to scan and monitor a talkgroup on a particular
trunked radio system.
Essential Trunking Talkgroup parameters
As a standalone object, a TRGP object is really no more
complicated than a CONV object. The trunking system (TSYS)
that the TGRP is a member of must be specified. Each talkgroup
has a digital “address” on the trunking system, which is called the
talkgroup ID, and this must be provided. We also recommend
that you label your TGRP object by giving it a name in the TAG
field. This will make it easier for you to find the TGRP object later,
and identify it when the scanner stops to monitor activity.
Setting up and using a Trunking System (TSYS) object
We just mentioned that the TSYS is an essential parameter
needed in order for a TGRP object to function properly and
receive radio traffic. The 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 the different types of trunked radio systems work properly
is provided in the Detailed Menu Reference. So, if all of this
makes sense to you then you should proceed and enter the
required data for the system you wish to monitor to make a new
TSYS as you create your TGRP. If not, please refer to the TGRP
section of the Detailed Menu Reference so that you will
understand which TSYS parameters are required for the type of
trunked radio system you wish to monitor.
The first time you make a TGRP, you must also create a TSYS
that contains the system parameters associated with the trunked
radio system itself. Once you create a TSYS object for a
particular trunked radio system, you can use the TSYS object
