Beyond the Basics

Notes	To listen to the transmission, the mode of the

programmed channel must be the same as that of the trunking channel (MO, ED, or LT).

When an ID code is received, the ID list for the bank is searched, and if found, the text name stored for the ID appears. If not found, scanning resumes immediately unless the bank is in open trunking mode.

Notes There might be more than one talk group transmitting at a time in some Motorola trunking systems. If you set the

scanner to manually tune in Motorola trunking mode, you will hear the talk group on that channel, but the display will alternate between all active IDs.

Frequency ﬂeet map and talk group information are also widely available on the Internet (for example, at www. trunkscanner.com).

In the past, groups that transmit frequently, such as police departments, could transmit on only a few frequencies. This resulted in heavy trafﬁc and often required 2-way radio users to wait for a speciﬁc frequency to clear before transmitting. Trunked systems allow more groups of 2-way radio users to use fewer frequencies. Instead of selecting a speciﬁc frequency to transmit on, a trunked system chooses one of several frequencies when the 2-way radio user transmits. The system automatically transmits the call on that frequency, and also sends a code that identiﬁes that 2-way radio user’s transmission on a control channel.

Your scanner lets you easily hear both the call and response transmissions for that 2-way radio user and therefore follow the conversation. For EDACS and Motorola (above 406 MHz range), the scanner monitors the control channel between each transmission to identify talk groups. For some Motorola (under 512 MHz range) and LTR systems, the scanner uses the subaudible data sent with each transmission to identify talk groups.
