I have a PSR-500, which has the V-Scanners and scanlists. I don't know if scanlists and scansets are the same thing, however.
Anyways, scanlists are for individual agencies, or in some cases, a group of agencies (usually closely geographically located). I'd like to seperate each agency to its own scanlist, but 20 scanlists aren't sufficient for the metro area, so I have to group a few agencies together. I still don't have enough room for everything. (I program by hand, which makes it somewhat tedious. If I had a computer and appropriate software, I'd redo them again, and maybe seperate the metro area into two seperate V-scanners, one for the West Valley where 99% of my time is spent, and a second for the East Valley that I venture to only rarely. State and county agencies would be duplicated in both, as would the Phoenix Regional Fire Dispatch system and other region wide systems. However, 20 scanlists still wouldn't be enough to properly seperate everything, so some grouping would still need to be done.)
V-Scanners are for different areas of the state, or if I want to break down a particular system by transmitter location or simulcast system. For example, using the Regional Wireless Cooperative (RWC) and TOPAZ RWC in the Phoenix-Mesa metro area, one of my V-Scanners is set up with Simulcast A in scanlist 1, Simulcast B in scanlist 2, etc. Then I set a wildcard to catch the TG's associated with each simulcast or stand-alone Intellirepeater site. As a new TG pops up, I press F3 to enter it, then if it's encrypted, I lock it out. Other V-Scanners have the AZWINS system or the Maricopa County system in them, again with wildcards. Another has a mix of systems with wildcards, as well as conventional stuff of interest in various scanlists. I have a couple of travel V-Scanners if I take a day road trip out of town.
