I just upgraded to the UR93 as the UR92 had difficulties acquiring locos with the YD7001. Actually the main problem wasn't acquiring locos as much as it was consisting them. Now that I have upgraded to the UR93, I too am not able to acquire locos wirelessly, but no problems when plugged into a UP5 panel.
Update: I found firmware updates available for the DT602D and the UR93 and flashed the new firmware. I still can't acquire a loco with either a DT602 or UT6, but have no problems acquiring or consisting with a DT402D.?
