I've been using Uniden's 536 since the first release and yes, there are a lot of MotoTrbo being used. I've updated the Trunking section as I've been monitoring the Southwest Airlines CAP+ system at Midway Airport. Found a lot of single-channel DMR channels, don't know who they are so haven't updated anything, but there is a lot to be monitored.
Some DMR additions to the Cook County Radio Reference database page, especially at O'Hare and Midway airports and in the attractions listings. No separate DMR list planed as far as I know, though.
Please submit your new DMR finds to the database so we can all listen to them!
