While not 100% guaranteed, the license makes it look to be conventional DMR vs. a trunked system...
Programming some DMR frequencies as conventional on these radios results in the radio just "hanging" on the channel with no voice (sound familiar?). You might look at programming it as a "DMR One Frequency" rather than conventional. I think that is less likely to "hang" in that mode. If you go this route, create at least one department and talkgroup (doesn't matter what TGID you use) and turn "ID Search" on for the "system".
