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 cannot be scanned by itself and is not considered
a Scannable Object. It is a “configuration object” that can be used
over and over again when adding talkgroups for a specified trunked
radio system.
LMIT – Limit Search or Search Range Object
LMIT objects contain the parameters necessary for the radio to
search a range of individual frequencies between a lower and upper
limit frequency.
SRVC – Service Search Object
SRVC objects are further divided into Public Safety, Aircraft, Amateur,
CB, Marine, and FRS/GMRS/MURS/DOT. SRVC objects are similar
to LMIT objects, but are preprogrammed to search all frequencies
associated with the selected service.
STLK – Signal Stalker II Object
STLK objects contain the parameters necessary for the radio to
rapidly sweep a range of radio spectrum for strong signals from
nearby transmitters.
Understanding your Scanner
Scanner Features
Object Oriented User Interface is designed for ease of use, yet is
powerful enough to satisfy the most sophisticated experts. Common
data entry, browsing and control methods are used for non-trunked
conventional channels, trunking talkgroups, search configurations and
Signal Stalker II setups. The radio grows with you—you can start out
with a small, easy to manage configuration, then expand it whenever
you need to.
Menu Driven Programming with Context Sensitive Help – Each
menu item provides a few lines of help text that provide assistance
with programming and using the scanner.
Scan List functionality allows you to arrange, group and scan objects
according to your preference.
Free-Form Memory Organization – Memory is assigned as objects
are created using a sophisticated internal file management system.
You are not constrained to traditional bank or channel scanner
memory layouts. The scanner can store over 1,800 conventional
channels, trunking talkgroups, search configurations, and Signal
Stalker II objects in any combination.
V-Scanner Technology – Allows you to save complete radio
configurations within the radio, for recall into main memory as
needed in the field. Twenty one V-Scanner Folders are provided,
each capable of storing over 1,800 objects. Total memory capacity of
main memory combined with V-Scanners is over 37,800 objects.
Skywarn Storm Spotter Functionality – Instant access to
frequencies used by storm spotter networks. You can monitor
storm conditions as they occur, and become aware of dangerous
conditions before the media or emergency management officials
announce them to the general public.
SAME and All Hazards Weather Alerting – Your scanner can
alert you to severe weather and other hazards in the specific areas
