Welcome to RR!
Are you near OKC or Tulsa? There are quite a few people near the metro areas, and the OKC guys (mostly, a couple of gals show up too) get together about once a month, and one of us will be glad to help with the programming. I think I've seen some of the Tulsa guys also meet up with new scanner owners to help program. Trunking is a total new beast from scanning of old, there's lots of things to learn, or at least take for granted. And some of the scanners don't have a real friendly user interface, especially if you're not sure what you are doing. That's where the software RolnCode3 mentioned comes in, not only are they easier to understand, but it's a lot easier to fix typos! And you can rearrange your channels/banks without having to re-type everything.
We probably have someone near you if trunking doesn't click, so just holler for help!
