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 for a particular trunked radio 
system, you must also create a TSYS that contains the system 
parameters associated with that trunked radio system. Once you 
create a TSYS object for the trunked radio system, you can use
