"There's a battle outside
And it is ragin'.
It'll soon shake your windows
And rattle your walls
For the times they are a-changin'." ~ B. Dylan
Circuit City puts it succinctly...
"HD Radio (Hybrid Digital, not High Definition) is the most significant advancement in radio broadcasting since the introduction of FM stereo more than 50 years ago. The new technology allows AM and FM radio stations to broadcast their programs digitally—a tremendous leap from the analog broadcasts of the past.
The technology behind HD Radio allows stations to broadcast higher-quality versions of their normal programming, as well as alternate formats not available on regular radio. And like traditional analog radio, HD Radio is completely free, with no subscription fees." (more) (find stations in your area)
