• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Triple trunking means that it will trunk track 3 (triple) types of systems - Motorola, LTR & EDACS.

so if i program a code in my scanner my scanner will still trunk codes automaticly it wont mess nothing up
What are you talking about? Where do you see CODES mentioned in the manual? You are dealing with frequencies and Talk Groups. I suggest you read the manual and learn the correct terms, then try to use the equipment.

Here's a simple explanation about trunking. Read this after you study the manual.

How a Motorola trunking system works

OVERVIEW:
The object of trunking is to allow many users to share a relatively few frequencies.
A trunking system is controlled by a computer. Information (data) is exchanged between the radios and the computer on a control channel, sometimes called a data channel. It sounds like a strong buzz.
A large system can have up to 28 freqs., 4 of which may be used as control channels. The control channel may be changed once a day or as often as the programmer decides. Some scanners need only the control channels to track the entire system. In that case just enter only the control channels.

After the frequencies are entered, the banks become scan lists or sub-banks that hold the Talk Groups or IDs.

Each group of users (Fire, Police, etc.) is assigned TALK GROUPS. In a Motorola Type II system, the most common type, TGs are usually in 32 number steps starting with 16 and going up to 65536; 16, 48, 80 --- 4656, 4688, 4720 --- 28944, 28976, etc. System radios can have more than 100 TGs programmed into them.

When a user pushes the talk button on his radio, data is sent to the computer. The computer chooses an unused freq. and sends that data to all the radios using the TG of the originating unit. This all happens in a fraction of a second and it happens EVERY time a radio is used.

EXAMPLE:
Fire Dispatch calling Engine 4 (TG 4528 on 856.7125)
Engine 4 answering Dispatch (TG 4528 on 867.2625)
Respond to 73 Elm Street (TG 4528 on 855.9625)
Engine 4 responding (TG 4528 on 858.4375)

If you have entered TG 4528 into your scanner, it will decode the control channel data and change your scanner freqs. to follow the conversation on TG 4528.

Some scanners have 2 modes, OPEN and CLOSED or SEARCH and SCAN.
OPEN or SEARCH receives all TGs using the system.
CLOSED or SCAN receives only the TGs YOU have put into the scan lists.

This should get you started, but you should read the manual carefully. You may need to read it several times.

When I bought my Pro-97 it took me a while to learn how to properly use it. That was a year ago. I love it, but I had to "search" many threads here to find all the info that was available. No sense asking a question that's been asked dozens and dozens of time before when I could find it myself. All the answers you need are on this forum. Search first, ask later.

Yup, its pretty bad when you get jumped on for posting a trunking question in the trunking forum... Maybe they should make it a little more clear for the new users what the trunking forum is used for.
