For most of you in here that have no idea what you're talking about when it comes to programming a Astro 25 XTS-2500 radio for conventional trunking scanning without affiliating with the network or transmitting on the system because it is illegal. Maybe you can all learn something from this video from a guy over seas who has some knowledge on this subject. Remember you can monitor a digital Astro 25 trunked system and you don't need a system key, just put the talk groups in Motorola format and the frequencies and it is possible. Just like a scanner.
