scannerface27,
If it helps at all I have a file I made up for SB county. I don't live there but I can hear some of the systems where I am, primarily System 8. I am in North San Diego County. I created this file for travel use and have used it so I know it works. It has all of the systems in it and a lot of conventional stuff for SB county.
You may be confused by my methodology at first but there is a logic to it. Also, I think you are confused by the TSYS concept. As others have said, a TSYS by itself does not belong to any scan lists as it is not a "scanable object" in the GRE lingo. Only talk groups and conventional channels can belong to a scan list so I am not sure how you made a TSYS fit into a scan list. In any case, to answer your question, yes, you can have different types of systems, Motorola 3600, EDACS, etc., programmed and assign the talk groups to whatever scan list you want to.
As to the V-Folders, just press FUNC + PROG and it gives you the option to Load (F1), Stor (F2), and Eras (F3). As your new at this I would first store what you have in a V-folder (you can override the factory programmed ones you don't care about - just erase an out of state one you don't think you'll need). Then, when you load a new one in just press F1 (Yes) when it prompts you as you are overriding the main memory with the new data from the selected V-Folder.
I am attaching my San Bernardino file with this post. I am sending it to you in .bin format because that is the standard file format that the scanner uses and I believe that ARC500 should handle that ok. I use WIN500 myself but it can save the files in .bin format as well as .p500 format.
Just stick with it and you will eventually "get it"! Take a look at my file - it might help you get a handle on how the programming works.
