Grecom PSR-410 - Talkgroup Object (TGRP)

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 the TSYS object over and over again
without having to re-enter all of the system data.
