I would agree that analog and digital coverage may well equal out for the normal listener.  DXers will put up with a lot more degradation of the signal than the average CUME denizen.

When I was listening to WOR on the Kenwood HD Radio, the analog was perfectly listenable to me.  If there was noise, I couldn't notice it.  The digital just wouldn't decode.  Again, I'd guess WOR has maybe .1-.3mv/m over Providence.  Way outside their Sphere of Influence.

The jury on the usefulness to DXers of HD Radio isn't even chosen yet, let alone deliberating.
