Conventional Frequencies and Trunking Talkgroups
The types of objects that the PSR-800 monitors while scanning
can either be conventional frequencies or trunking
talkgroups. While the PSR-800 is designed so that you can use
it without knowing the difference between a conventional
frequency or a trunking talkgroup, you may find it helpful to know
more about how these objects work and what you can do to
optimize the PSR-800 for best performance.

A conventional frequency is nothing more than “plain old radio”
consisting of a single radio frequency that is typically broadcast
from a single radio tower or building rooftop radio site or directly
from mobile or portable radios. When browsing the PSR-800ʼs
library, you will most often find conventional frequencies in the
Categories or Agencies sub levels beneath States or Cities/
Counties. Youʼll know youʼve browsed to a conventional
frequency when you see the word “Frequencies” on the top line
of the display while you are browsing the library. A conventional
frequency stands alone in the radio - it has no dependencies on
other Library elements. In other words, feel free to import
conventional frequencies individually or as groups without
worrying about dependencies.

Trunking talkgroups work differently and can potentially be more
complicated to deal with. A trunking talkgroup is a part of a
trunked radio system - a modern and complicated radio network
that is managed by sophisticated special purpose computers.
Trunking technology allows many different groups of radio users
to share a relatively small number of radio channels. Youʼll know
youʼve browsed to a talkgroup when you see the word
“Talkgroups” on the top line of the display while you are browsing
the library. When browsing the PSR-800ʼs library, everything you
find below the “Systems” level under States or Counties/Cities
will be trunked radio systems and associated sites and
talkgroups. Unlike conventional channels, trunking talkgroups
