The way I understand it, all DT channels are in the UHF band for now.  When
everything is converted over, they will move the DT channels back to VHF,
and the upper band of UHF will be (and some already has been) sold off.
Remember when UHF used to go to 83?  It doesn't go that high anymore (I
think it is somewhere in the 50s).  And after everything is DT, UHF won't go
that high.  At least, that's the way I understand it.
