My PD22 (not UE) won't properly tailstand but if I position the clip to just the right position, it will act as a third support leg and tailstand at a slight angle.
The PD22 or the PD35 will not table stand but there are plenty of easy solutions to make it tail stand.I use my PD35 nightly to wind down with the radio after finishing with the tv and I made it table stand very simply.
My PD22UE came with the diffuser. If I take off the belt clip, it sits nicely in the diffuser aimed upwards. Not the best solution, but works fine, and is free.
