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 help section of
the EZ Scan software.
IMPORTANT: 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.
