I have one. Love it. Many people have them.
Here's my two cents.
(about what Spitfire8520 said, only much more long-winded)
Programming talkgoups is not difficult but it can be very confusing at first. I was extremely confused until the light bulb went on. It's simple after you've done it a few times.
Relax. It's neither rocket surgery nor brain science. It may take a little time.
Here's the deal: To program a talkgroup you need to program a system, and to program your first system you need to create a talkgroup.
As confusing as that sounds, it actually makes sense. You can't put a system in a scan list (at least not directly) but you can put a talkgroup in. As part of programming your first talkgroup, you program the system.
First things first, you need to identify a control channel you can receive. In your original post you had a link to StarCom21 Statewide Illinois P25 Trunking System. That page shows a lot of sites. Find what you think is the closest one to you. You can program the control channel (shown in red) as a conventional channel and see if you hear a continuous buzzing/humming sound. The bottom line of the display may begin "Sy:" or a percentage, followed by a site ID number or maybe some other stuff. Exactly what it says is not important. When you receive a control channel, you're golden, especially if the decoding percentage is high. The frequencies for that site are the ones you program into the system you create when you create your first talkgroup. Make the system type P25 Auto and the order of frequencies shouldn't matter. You can make your first talkgroup a wildcard. That's the gist of it.
Again, you need to identify a site close enough that you can receive the control channel. If you can't receive a control channel, it won't matter what you program.
1. When you're checking to see if you can receive a control channel, you can use 'Tune' rather than programming an object. It's easier.
2. When you create a P25 Auto system, the only frequency you absolutly need
is a control channel frequency. The scanner can read the voice frequencies off the control channel.
