I'm putting a wiki together for radio IDs to use with the new BCDx36HP scanners. It can be found here. I might break it down into individual county/town pages in the future if it becomes to big for one page. Feel free to add what you got, just use the same format. I basically try to have the mobile radio in the vehicle/apparatus as the main radio ID, and use a/b/c/d for the portable radios when I can narrow them down.
