Wasn't sure if this was the best forum to ask in, but it seems that DCR is available on some ICOM radios, perhaps region dependent, but I am trying to gather a bit of information on DCR Digital Voice.
What I have currently figured out is that DCR is in essence just using NXDN48 with a non-standard lich code for voice, and I can now sync with it and decode the voice.
What I haven't been able to work out is whether or not there is any data carried. There appears to be data carried during voice, but it doesn't seem to work quite the same way as the NXDN sacch frame. I can get good CRC checks like a sacch frame, but what I cannot get is a message in the sacch frame that makes sense.
So, what I wanted to do was ask anybody who has radios that operate in this mode a few questions.
When you program for this mode, is there a TG, RID like values that you can program in? Group Calls or Private Calls? Channel numbers? RAN (or RAN-like values?) and so on? Aliases? Can these radios in DCR mode send text messages or other data?
