As Enforcer has noted, the Will County system uses a simulcast site, and for the agencies in your county, using the statewide STARCOM21 system, that system's site in your county is also simulcast. Simulcast can be a problem for scanners other than Uniden's SDS series. See this Wiki page for more on Simulcast, as well as suggestions as to how to deal with it. Simulcast distortion is extremely location driven. Depending on exactly where you are, relative to the sites, you might be lucky & not have a problem. Or, it may be extremely challenging, if not downright impossible, to deal with. Even the exact spot, in your home or where you are using the scanner can make a difference. Sometimes, a move of only a couple of feet in one direction or another can be the difference between decent reception, or frustrating problems.I get that now. Thank you, ill just have to figure out how to program everything in. Looks time consuming
For your county's system, there are two sites listed. The main simulcast site, and a site in Braidwood, to improve coverage in the southwest part of your county. That second site (Braidwood) is not simulcast. If you are lucky enough to be in range of that specific site, you might be able to avoid simulcast issues on your county's system.
The best, and quickest, way to program your scanner is using software. Besides being quicker, you also can more easily review your entries, and spot something that might need correction or adjustment. If you were to become a premium subscriber, you can quickly & easily import exactly what you want from the main RadioReference database.
However, even if you do not upgrade to premium, the software programs available for your scanner have a method where you can copy frequency & channel information from a database web page and copy that into a programming file. The best software is, in my opinion, ProScan. That software has a free trial period to try the program before buying it. After the trial period, the cost is $50. That's a one time fee, and updates to the program are free whenever one is issued. Besides your 325P2, ProScan also covers a large number of other Uniden scanners, both current models, as well as some that were discontinued a decade (or more) ago. ProScan has a procedure that allows you to copy data from a web page and import that into a programming file.
FreeSCAN is another software program that covers your scanner, As the name implies, the cost is free. It was long since abandoned by the original author, and has not been updated since. However, it will work for your 325P2. See this Wiki page for a FreeSCAN user guide, FreeSCAN has a feature called EZ-Grab which allows you to copy frequency & channel details from a web page and paste that into the programming file. That is detailed on the Wiki page linked,
Butel also makes software that covers your scanner, but as noted, my preference is ProScan.
