DMR Dump...any ideas what it does?

[radionx]

Hi everyone

I fired up DSD+ and was able to dump a, well at least I think it is, a DMR T3 CC...or could it be some kind of data modem? It is only periodically active, about every 30secs for a few seconds.

Slot 2 seems to be silent, but in slot 1 I see data. What do you think...is it a data application running here?

Sorry, wrong file. This one is of interest...it's a constant signal, and it shows as TIII. Has been going on for months now...seems like a voice-wise silent system, broadcasting nothingburgers?

Looks like an alternate control/registration channel.
