To anticipate your follow up questions (note that anything in blue is a link of some kind);
a. To understand what trunking is and how it works, read the Overview section of
Trunked Radio Systems - The RadioReference Wiki
Note that you will need Adobe Acrobat (or one of the compatible readers, such as Foxit, or Chrome) to read one of the links. There's an article there by our own UPMan that does a very good job of explaining the concepts
b. Now what you will need to get that data into your scanner? See this article for all the links I'm about to mention;
Programming Your Radio Shack Scanner - The RadioReference Wiki
1. We have a programming shortcut for that scanner if you want to do it manually, but I hope your dental insurance is paid up, because there will be teeth knashing;
2. To download data from our database, you will need 3 things; a compatible USB-serial cable, an application and a subscription. You can find the SKUs for the USB-serial cable, along with some hints on how to use Windows Device Manager in the 'Connecting scanners via USB' article as mentioned in the prologue
.
3. The 3 most popular applications for this scanner are ARC500, PSRedit500 and Win500. We have links to user guides for ARC500 and Win500 in the Software section; also in that same section is an article called 'Object Oriented Scanner Software', which has the links for these 3 packages;
4. You can also get a premium subscription, which each of those 3 packages supports...this will allow you to download data directly from our database
Premium Subscription Information Page
If you choose one of these apps, perhaps someone can send you a file to get you started. Be sure to be very specific about which one you have - formats are not interchangeable
5. Finally there's an Easier to Read manual for this scanner; and a printed version can be had from Scanner Master.
