Trunked modes (MO, ED, and LT) can only be selected for frequencies above 137 MHz that use trunking operations.

Trunk Scanning

In each bank, you can mix conventional channels and frequencies in a bank. However, you can scan only one trunking mode at a time, either EDACS, Motorola, or LTR.

To focus on trunk scanning, during a normal scan, you turn off banks that contain only conventional channels.

For Motorola channels, your scanner displays the Talk Group ID memory location, received frequency, voice channel (VC), and the Motorola ID number.

To change the scanning direction, press or .

Your scanner automatically mutes the audio while it decodes control channel data. However, we recommend you turn SQ clockwise and leave it set to a point just after the hiss stops. This lets the scanner quickly acquire the data channel.

For Motorola trunking systems, more than one talk group can transmit at a time. If you manually tune the scanner, you will hear the talk group on that channel, but the display will alternate between all active Talk Group IDs.
