For a current review of several aspects of HD Radio, see the
latest issue of "Sound & Vision" Magazine, November 2005,
pages 99-101, article titled: "HD Radio: Ready for Prime
Time?" by Ivan Berger.
It includes sections on, New and Improved, Need the Info,
Battling the Satellites, Where the Stations Are, and HD
Radio in the Real World.  It should clear up some of the
confusion -
