Say you live in San Diego CA. You might want to get FreeSCAN, download the entire public safety trunked system (check off the offline sites) and see what you get. I find and prefer FreeSCAN for downloading and re-tagging alpha tags (and has a better duplicate channel finder), but use bcTool for primary organizing and other work.
Got the problem. Your scanner is junk. I'll give you $50 for it. Or I can trade you mine for yours, and program all the local systems and freqs for your state.
