HD Radio

Move Over, HD-TV. Now There’s HD Radio, Too.: We don’t even have digital radio around here, much less HD. Of course, to listen to HD radio, you have to have an HD receiver, which is about $500.

The radio industry, like broadcast television before it, is switching to digital technology. With digital technology, AM stations sound like FM, and FM stations approach CD’s in sound quality. A retrofit to HD Radio, or high-definition radio, costs about $100,000 per station.

The industry once believed its future would be secure simply by switching to digital technology, but the popularity of satellite radio, MP3 players and Internet radio has changed the game plan.

Unfortunately, the AM HD radio system creates sideband interference that is so strong that the system can't be used at night. So far, there seems to be no solution.
