Hi gang,
Anyone know of an sites of folks doing homebrew HD radio demods? There
are several sites out there for doing shortwave DRM (Digital Radio Mondale),
but I'm wondering if any efforts have been made to build similar
hardware/software for the HD radio broadcasting that takes place on the U.S
AM broadcast band.

Haven't heard of any.

Unlike DRM, HD Radio is a proprietary protocol, I don't *think* they release enough details to implement it unless you're a chipmaker who's paid the
royalties.

(I suppose one could reverse-engineer it -- to my knowledge there is no encryption involved)
