That simply tells me what the message look like from the radio to some program. I understand that. Where is there something that tells me what things like '3C0,0,4900' or '30B,0,2021' mean? I know that's the data from the control channel. I want to know how to turn it into something meaningful.
Reread it...it tells you step by step in those box diagrams how to decode that info.
Just have to spend a little time studying the info brother!
