Digital Trunking.?

Question

I just got myself a new Radio shack Pro96 Digital Scanner last week. I have the Frequency that I am currently listening to right now. I also have the ID#'s. But how do I put them into my Scanner? I know "Nothing" about Digital trunking. Thanks.

Answer 1

First there is Trunking, which is using standard FM modulation, and at least 3 frequencies. One frequency will be a control channel, and will not have any voice. It determines what channel is open, and who is using it. Trunking is shared by many users, who may or may not want to hear each other. Users are given an ID, which defines the talk group. Users within that talk group will only hear each other within the same talk group, even though there are multiple talk groups using the same frequencies. When you load in the frequencies, and start listening as trunked, you will hear ALL the talk groups, unless you filter to a specific talk group. To actually do this, look at the link below, and select the Motorola Trunking section.

Digital trunking is similar, where there are multiple users using the same frequencies, the difference is there is no actual modulation. All the audio is provided in a digital format (AKA P-25). You must set the scanner to decode the digital audio, by selecting the baud rate, and modulation scheme

Answer 2

The simplest way to program the scanner for new users is to get software and interface cable.
