Digital and Trunked Systems

Your BC785D is designed to monitor APCO Project 25 digital communication systems (using optional BCi25D) and tracks three major types of trunked radio systems. These systems are described here.

APCO Project 25 Systems - Digital systems which support the APCO Project 25 protocol developed by the Telecommunications Industry Association (TIA) and Electronic Industries Alliance (EIA). Systems can operate in conventional, trunked and mixed- modes (analog and digital) in any frequency band including UHF, VHF and 800 MHz.

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, and recent systems are appearing on other bands. (See page 63).

EDACS - Including "Wideband" 9600 baud, and "Narrowband" 4800 baud systems. "Wideband" systems are mostly on the 800 MHz band, and are used by public safety, utilities, and business users. Some systems are used on the VHF and UHF bands. "Narrowband" systems are used in the 935-940 MHz band, many by utilities.

(See page 58).

EDACS SCAT - These systems are mainly used in the Midwestern United States and are one-channel trunking sites using the EDACS format.

LTR - These systems are mostly for business users, and found on the UHF, 800 and 900 MHz bands. (See page 62).

For details on the operation and programming for all of these systems, see pages 45-71.

When tracking these types of systems, remember these important points:

Your scanner defaults to monitor Motorola Type II systems; however, you can change this if the system in your area is different. (The types of systems are discussed below.)

The frequencies for many of the trunked public safety systems are listed in the TrunkTracker National Public Safety Trunked System Frequency Guide included with your BC785D scanner. Frequencies sometimes change, check with www.bearcat1.com/free.htm.

If you have internet access, you can visit scanner.uniden.com or www.bearcat1.com/free.htm for additional information, for current news and frequency information, about Trunk Tracking Scanning.
