Welcome to RadioReference. A bunch of us in the area just met to help people with issues just like yours. Unfortunately, we've only been meeting about once a year.
Since you are in Sacramento, I suspect you want to program one (or both) of the two trunked radio systems. Regardless of how technical you are, I wouldn't try it by hand. Software can take 99% of the pain out of the process; whether you "download" (import) data from this site or hand enter it into the software, it's the only way to go in comparison to hand-programming these modern scanners.
