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.)
•If you have internet access, you can visit www.trunkscanner.com for additional information and for current news and frequency information about trunk tracking scanning.
