DMR has been the topic of the last two Ham Radio Workbench podcasts.
They’ve taken a fairly deep dive into the subject which I found very interesting since I’m a DMR user who has managed to fumble my way to some success despite it remaining mostly a mystery to me.
Most of my technical questions were covered by these two programs.
It took me more than a week to get thru them both as they run over two hours each. Worth the time if you’re interested in more than just a casual introduction to this digital mode of communication.
The links they’ve collected in the show notes (click Read More) of both programs cover the entire DMR galaxy and it would be worth your time to click over and have a look just for the high-value linkage.
