Following yesterday's article on HD Radio's Dirty Little Secret, a reader found this RFP (PDF) by the Corporation for Public Broadcast (CPB) to investigate reported problems in HD Radio's coverage. The reports indicate that the HD Radio signal not only has less of a reach, but also interferes with the regular analog AM/FM radio signal.

Terrestrial radio's biggest advantage is their reach. Everyone has an AM/FM radio, and nearly everyone can get signal for free. Take away that, and you've got a serious problem.

Thanks Bud!
