Understanding your Scanner
objects are used to store the parameters for
any radio channel that is not a part of a trunked
system. For example, if you want to monitor
specific VHF marine channels, they should be
programmed as CONV objects. If you want to
monitor your favorite amateur radio channel, it
should be stored as a CONV object. If your police
or fire department uses a channel, or channels
that are not trunked, but part of a "plain old radio
system," they should be stored as CONV objects.
TGRP – Trunking Talkgroup Object
Trunking Talkgroups are "virtual" channels that
exist on a trunked radio system. A trunked radio
system is a radio system where a small group of
radio channels are automatically shared between
a larger number of users and user groups. This
sharing of channels is managed automatically by
a special computer, called a controller, or by other
specialized hardware. If you want to monitor a
talkgroup on a trunked radio system, you must
store that talkgroup's parameters in a TGRP
object.
TSYS – Trunking System Object
A TSYS is a special object type that is used when
creating TGRP objects. A trunking talkgroup
must be associated with a specific trunked radio
system in order for it to operate. There are
parameters that are associated with trunking
systems, such as the type of trunked radio system
technology used, the frequencies that the system
uses to broadcast control data, etc. Instead of
entering these parameters over and over again
every time you create a new TGRP, you create a
TSYS object with all of the system parameters,
then specify that TSYS object for each TGRP you
create on the same trunked radio system. A TSYS
