Sorry for the late reply. My scanner displays the UIDs but they are really slow at displaying. That is on the 436HP. I know when I still had the PRO-106, I could adjust the EDACS unmute timing, all the way to the point of hearing the channel grant data streams. Never missed a UID with that one. It seems like the Uniden scanners cannot be adjusted so the default unmute timing on them might be just long enough to be missing the UIDs of the officers. I do, like Bolt, always see the dispatch console(s) UIDs. When I had my Harris P7100, it always displayed the UIDs without fail, as Elroy stated.
