One thing you will notice about just about all the digital voice systems out there is they have the capacity to transmit non-voice data as well.
Apco P25, for example, has native support for binary transmissions of 4,800 baud, with possible additional capacity. Some of the early demonstration radios I saw had a serial port and could work as a TNC
D-Star has a data mode
Provoice has a data mode
even NXDN has a data only mode
In practice are these ever used for anything? Dispatch? Paging? Mobile data terminals?
My guess is that they were probably included with the idea that they would use the same system to power the MDT's as for voice, but once 4g came around, it was a nobrainer to go with that.
Are they used at all?
IF so, is there a way to decode them? Would DSD be smart enough to realize it was monitoring a mode that was not speech and then show the text or pipe it to something?
