Let me jump in here and make a few comments to those that may or may not be fully understanding of the P25 specs.
1. Unless something has changed, there was no requirement for a systems key to be able to allow the radio to function on a P25 trunking system. Motorola and other vendors added that requirement to reduce the number of cloned and illegal radios being on the trunking systems.
2. The P25 specs require that a radio register on the trunking system before the radio can follow and listen to any talkgroup on that system. This in essence removes the ability of any trunking radio on the newer 9600 baud systems from being used as a scanner without affiliating. There are some radio geeks that have found a way around this with special programming tricks, but it is not for the new comer to attempt.
3. I don't know of any trunking system manager that will allow his system key to be obtained to program a radio on his system without approval. Those that do program a radio on a trunking system without authority, will have to bear the full extent of both state and federal prosecution.
4. The scanner group that keeps complaining about how hard it is to get a trunking radio set up for monitoring a trunking system seem to forget that that system isn't there for them to use as a toy. If you really want to listen to it so bad, it is cheaper to just get a digital scanner and stay out of the threat of any legal activity coming your way.
