know both the frequencies used by the system and the LCN for each frequency so that you can program the frequencies in LCN order. Agency-Fleet-Subfleet - talk group ID's for EDACS systems are assigned in a way that makes it easy to see at a glance the affiliation of the user. Each radio is assigned a 2-digit agency identifier from 00 - 15. For example, 01 might be used by the police, 02 by ambulance service, 03 by the fire department, and so on. Each agency is then subdivided up to 16 times to provide fleet identification, and then 8 more times to identify subfleets. For example, the complete AFS for the Police Department West District's dispatch channel might be 01-062. 01 identifies the agency as the police department, 06 identifies the fleet as the West district, and 2 identifies the subfleet as the dispatch channel. While these assignments are somewhat arbitrary and vary from system to system, there are many resources on the web for finding the assignments for most systems. Because of the logical hierarchy of the AFS system, your BC898T lets you assign wildcard ID's that let you, for example, use only one ID memory to identify all units in either an agency or a fleet. EDACS SCAT - EDACS SCAT (Single Channel Autonomous Trunking) systems operate on a single channel and alternate control data with analog voice traffic. While your BC898T cannot track ID's in this system, it can eliminate the control data so that all you hear is the voice transmissions when you monitor this type of system.

Users on an LTR system are assigned to specific talk groups, which are identified by the radio as six digit numbers.

LTR Trunking

LTR (Logic Trunked Radio) systems are trunking systems used primarily by business or

private communications service providers, such as taxicabs, delivery trucks, and repair

services. These systems encode all control information as digital subaudible data that

accompanies each transmission, so there is no separate control channel. Users on an LTR

system are assigned to specific talk groups, which are identified by the radio as six digit

numbers.

These numbers are in the form AHHUUU, where:

A = Area code (0 or 1)

H = Home repeater (01 through 20)

U = User ID (000 through 254)

When the scanner receives a transmission on a channel set to the LTR mode, it first decodes

the LTR data included with the transmission. In the ID search mode, the scanner stops on the

transmission and displays the talk group ID on the display. In the ID scan mode, the scanner

only stops on the transmission if the LTR data matches a talk group ID that you have

stored in the bank’s talk group ID list and have not locked out.

LTR systems are frequently

programmed so that each radio has a unique user ID. LTR systems also need to be

programmed into your scanner in channel order.

Since many LTR systems use only odd-numbered channel slots, you would program these

systems using only the corresponding odd-numbered channels in a bank (for example,
