The Basics

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

Motorola trunking systems come in three categories: Type I, Type II, and Type I/II Hybrid. Each category displays and uses talk group IDs in slightly different ways.

Motorola Type II IDs are in the form FFF-SS, where;

FFF=Fleet ID

SS=Subfleet ID

Type I systems are usually organized with different user groups assigned to different fleets.

Notes

For example, a valid fleet-subfleet ID identifying all

detectives within a police department might be 000-12, where 000 identifies all police users and 12 identifies the Detective division.

Tuning the scanner to an active control channel while in Motorola mode will display the Motorola System. ID and the approximate control channel message decode success rate. This information can help you identify the Motorola trunking system that you are monitoring and the receive quality of the control channel signal.

To properly map the raw Type I data to the correct fleet- subfleet format, you must program the correct fleet map into the scanner. Fleet map information is widely available on the Internet for most Type I systems in use.

Type II system talk groups are identified by a 5-digit number. Valid talk group IDs are divisible by 16. If you try to enter an invalid talk group ID, the scanner rounds the ID down to the next valid ID.

Type I/II hybrid systems use both fleet-subfleet and 5-digit formats for talk group IDs.

Notes

If the scanner decodes control channel data while receiving transmissions from a Motorola trunking system, CNTRL appears on the bottom line of the display.
