The fox to guard the hen house...

IBiquity's comments about why the FCC should allow all-digital with AM-HD IBOC. I'm for all-digital operations, but I'd like to see DRM get a crack at it!

Does anyone out there have access to any scientific research showing that AM-HD can survive the rigors of skywave propagation (even half as well as DRM30)?

That is what I thought! I call to your attention again a RadioWorld article I linked to last year.
