Thanks for the input picked up a PRO96 digital scanner.
Yikes! That's a heavy-duty scanner!
I took a look at the manual (downloaded from the RS website), and yours has a preprogrammed search for CB. Look on page 52 of your manual.
If you have a PC, you can buy a connector cable and software to load frequencies, information, etc. into your scanner (not much out there for Macs though). There is a book called "Police Call Book" you can buy at Radio Shack that has frequencies for just about every location in the US, but I think there are something like 7 or 8 regional books to cover the whole country.
Here is a site that contains a wealth of information and a forum:

There is also a database on the RR site that contains frequencies for just about anywhere. This site just stared about half a year ago, and it's continually growing.
Be sure to read through your manual a few times to get acquainted with your scanner. They can be tricky to program unless you fully understand what you're doing (especially trunking). Also, if you bought your scanner new from RS, be sure to check their website over the next month. I think that if your scanner goes on sale within 30 days they will refund the difference to you.
Good luck, you have a really nice scanner!
