The link has nothing to do with the Denver Post saying anything about HD. It's a virtual reprint of an iBiquity press release, with the same old tired shibboleths ("AM will sound like FM, and FM will be CD-quality") that have been repeatedly disproven. It also hypes the secondary channels, regardless of the fact that they will never cover enough land area to be profitable and most of the people who read that paper won't be able to hear them.
God forbid a reporter should actually do some legwork and get a legitimate story instead of retyping a press release.
