For example, Police  East Patrol might be assigned to group 12, making the full Fleet, Subfleet ID be 000-12. To properly map the raw Type I data to the correct fleet-sub- fleet 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 systems 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-dig- it formats for talk group ID’s.

Note: Since the subaudible data is included with every transmission, you can generally receive Motorola sys- tems from further away than when using systems that only decode the data channel (like the EDACS mode). However, as the signal quality worsens, or if the signal is subject to interference, the scanner might not be able to reliably decode the talk group ID. In this case, you might occasionally notice that the talk group ID changes during a transmission.

EDACS Mode

This sets the scanner to decode the talk group ID’s used with an EDACS (GE/Ericsson) system. This is a trunking system used primarily by business or private communica- tions service providers, as well as by some public safety organizations. EDACS systems transmit active talk group information only on a dedicated control channel.

EDACS frequencies are organized in a specific order. Each frequency is assigned a Logical Channel Number (LCN). For the PRO-92 to correctly switch to an active frequency, you must program the frequencies in LCN or- der, starting with Memory 01. EDACS talk group ID’s are entered as a 4-digit decimal number from 0000 to 4096.
