"Answering HD radio questions"
"Then as now with HD Radio, the FCC said it would let "the market" decide. However, when they really care they insist on market compliance. That's what's happening with over-the-air (OTA) HDTV, with rules requiring that all TV stations broadcast in digital form somewhere on a shrunken UHF band, so large hunks of legacy TV spectrum can be sold off... It might be nice if HD radio succeeds. But I doubt it will, because, unlike HDTV, there is no mandate by the FCC that every receiver be HD ready by a certain date. (Or is there? I don't think so.) But, unlike HDTV, it doesn't impose a nearly prohibitive engineering burden on the stations that need to put it in their audio and transmitting chain. And no HD radio station is being asked to vacate their old channels so the frequency can be sold off by the feds."
