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.
Assuming that you have already entered one or more CONV objects (which we recommend you do prior to
attempting the entry of the slightly more complicated TGRP object), you should press the PGM key to place
your scanner into Program Mode, then press the NEW softkey, then press the TGRP softkey. Your radio
display should appear as follows:
illust
In the same way as with the CONV object, this menu of TGRP parameters can be scrolled up and down to
access and enter or change the various parameters associated with a trunking talkgroup.
For the purpose of this example, we will assume that you wish to create a TGRP object for a Motorola Type
II 800 MHz trunked radio system, which is one of the more common types of trunked radio systems in use.
(If this is not the case, we encourage you to refer to the Detailed Menu Reference section of this manual for
more information that applies to the type of TSYS you wish to monitor.)
Scroll the display by pressing the down arrow once so that the flashing cursor is highlighting the TSYS field,
then press the SEL key in the center of the 5-way pushbutton pad. Your radio's display should appear as
follows:
illust
We are entering a new Motorola Type II 800 MHz system, so we can leave the Type: field as-is. It's a good
idea (in fact, a REALLY good idea, for reasons you will see as you proceed) to give your TSYS a unique
name. Press the down arrow key once to scroll to the Tag: field, then press the SEL key and enter a name
for the system using the methods previously described for naming your CONV object. We will use the tag
My System for this particular example in the documentation:
