Answer by wires
A trunk tracker enables you to listen to conversations on trunked radio systems. Trunked radio systems use several frequencies on a shared basis. The radio system assigns the frequency on a request basis. If you listened to just one frequency you would hear part of one conversation, then part of another, then part of yet another conversation. The scanner can decode the frequency assignments and switch to each frequency to hear just one complete conversation. In other words, it tracks the conversation so you get the complete story.
