smart train

I have a SDR that I would like to use to broadcast a system that is NXDN. I have yet to find a way to decrypt NXDN and broadcast it to the internet. Does anyone have any suggestions? Also if you know, can I have more then one feed broadcasting from the same computer at the sometime?

Good afternoon. I'm tying to listen to SMART Train Communications. According to Radio Reference it is NXDN. I think I'm listing to a control channel and that is is NXDN 48 - Correct me if you think differently. Sample of what I'm talking about...
