Beyond the Basics
trunk tracking
Your scanner tracks three major types of trunked radio
systems. These systems are described here.
MOTOROLA - Including Type I, Type II, Hybrid,
SMARTNET, and Privacy Plus. Motorola systems are
widely used by public safety and business users. Most
are on the 800 MHz band. Recent systems appear on
other bands. (See “Tracking Motorola Systems”).
EDACS - Including “Wideband” 9600 baud and SCAT.
“Wideband” systems are mostly on the 800 MHz band,
and are used by public safety, utilities, and business
users. Some systems use VHF and UHF bands. (See
“EDACS Tracking”). SCAT systems are single channel
EDACS systems, and are mainly used in the midwestern
United States.
LTR - These systems are mostly for business users,
and found on the UHF, 800 and 900 MHz bands. (See
“Tracking LTR Systems”).
When tracking these types of systems, remember these
important points:
Your scanner defaults to monitor Motorola Type II 800;
however, you can change this if the system in your area is
different. (The types of systems are discussed below.)
