Hint: While scanning, you will not know exactly whom the talkgroup IDs are assigned to until you listen awhile or until you locate talkgroup ID lists in frequency guides or on internet sites such as www.trunkscanner.com. With- in a few minutes, you can usually fig- ure out if what you are listening to is a police, fire, or emergency medical 2- way radio user. Other talkgroup IDs might take some time, but determining whom each ID represents is half the fun of trunk scanning!

Turning Banks On or Off During Trunk Scanning

As in conventional scanning, you can turn each channel-storage bank on and off during trunk scanning. When you turn off a bank, the scanner does not scan any of the 50 channels in that bank.

1.Press DATA. All active trunk bank numbers appear.

2.Press the number key for the bank you want to add or delete.

If the bank number is off, the scanner does not scan any of the channels within that bank.

Skipping the Trunked Bank

To skip to another trunked bank while you are listening to a trunked bank, hold down DATA.

Turning Status Bit Ignore On or Off

You can set how your scanner works with status bits (also called S-bits), let- ting you control how the scanner inter- prets and displays talkgroup IDs.

The last four bits of a Motorola Type II talkgroup ID (a binary 16-bit code) are the status bits. In some systems, sta- tus bits identify special situations (such as an emergency status).

Your scanner is preset to assume that the status bits in a talkgroup ID are set to 0 and ignores them. For example, when the scanner receives the talk- group ID 010111001110 0011, it reads the ID as 010111001110 0000 and converts the first 12 bits of the ID to 23776 (the talkgroup ID). However, since the status bit value is 3 (0011 converted to decimal equals 3), the ID is actually 23779.

If you are scanning a Motorola Type I system and do not have a fleet map for that system, you might have to turn off status bit ignore in order to deter- mine the proper fleet map.

Important: If you are scanning any system other than a Motorola Type I system, be sure status bit ignore is set to ON or you will miss some transmis- sions.
