have dependencies - at least one site from the system must be
selected in order for picked talkgroups to imported to Scanlists.
There are many different manufacturers and flavors of trunked
radio systems, each with their own special programming
nuances. Fortunately, the PSR-800 takes the guesswork out of
programming talkgroup objects. You simply browse the library to
find what you want to hear, and regardless of whether it
ʼ
s a
conventional channel or a trunking talkgroup, most of the time it
ʼ
s
as simple as picking the objects you want and importing them to
your desired Scanlists.
There is one key difference between trunking talkgroups and
conventional channels. A conventional frequency typically
operates from a single tower or building rooftop site. A few
conventional systems may have more than one site, but they still
use the same frequency, so there are no special considerations
for programming these in the PSR-800.
On the other hand, trunked radio systems consist of one or more
discrete
sites
strategically located throughout the service area of
the system to provide the desired level of coverage. Each site
has its own set of frequencies. One type of trunked radio system
technology known as “simulcast” has multiple radio sites that all
operate on the same set of frequencies - to the trunked system,
a simulcast subsystem appears as a single site.
It
ʼ
s important to understand that at least one Site for a system
must be selected when you are importing talkgroups from the
Library to Scanlists. Many of the talkgroups you pick will be a
part of systems that have only one site, and you need only
ensure that this one site is also selected when you import.
In cases where there is more than one site to choose, you have
a few options.
In every case, the easiest way to bring in a system
ʼ
s sites and
talkgroups is to simply place a checkbox next to the system
ʼ
s
name after you drill in from the Systems level of the library from
either the States or Counties/Cities level. This selects every site
in the system, and every talkgroup as well. For example:
•
Access the Library from the Main Menu
•
Scroll to Indiana and press the
key
•
Scroll down to Systems and press the
key.
