Brandmeister will not pass traffic on their network if the radio is using a Capacity Plus compatible ID. Other DMR networks may vary and I'm pretty sure there are others out there that do still allow Capacity Plus compatible IDs since you can still get them from radioid.net.
Your traffic will pass in local repeat on any talkgroup on just the repeater you happen to be on, however it will not go wide-area, even through a wide-area talkgroup on that local repeater.
Unfortunately, with a Motorola DMR subscriber, you are locked into one radio ID at a time, so your options are to either reprogram every time you want to use a different system (commercial Capacity Plus vs. amateur) or you can carry two radios. Not real convenient, I know.
