Wow this would be so cool. There's few ham bands with enough bandwidth that's not already tied up in band plans. 23cm perhaps? I wish gsm had a group call mod

The closely related tetra standard does but it doesn't seem to have attracted much interest from hams despite having more timeslots than dmr and pretty small bandwidth requirements (25kHz iirc)
