experiment with the different settings. If you make a change that you aren't certain about, press the Dflt
softkey to restore the setting to its original values.
When you're ready, simply press the Save softkey to save your new conventional object. Once the object is
saved, you can continue to enter other new objects, or press MAN to listen to the CONV object you just
entered, or SCAN to start scanning!
NOTE: Your scanner uses Scan Lists as a way to group objects together according to your preferences for
scanning. By default, all new objects are mapped to Scan List 01. There are a total of twenty regular Scan
Lists in your radio, a special Favorites Scan List, and a Scan List to hold Skywarn objects. Scan List
membership for an object is 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.
NOTE: When entering data into a numerical field, you can start typing as soon as you have scrolled to the
desired field, which will replace the contents of the field with your new entry. Alternatively, you can press the
> key, which will preserve the original contents of the field so you can make small changes without retyping
all of the data.
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
