Alex, Here is information on HD Radio gathered from a Google search:
Kevin, article below HD Radio is a brand name of a method of digital transmission of AM and FM radio stations . The HD Radio system is unique in that it allows stations to broadcast high quality audio and a variety of text-based services, as well as additional FM channels, without changing to new frequency bands. "HD" originally stood for "Hybrid Digital/analog", not "high-definition" (as in HDTV ). Presently "HD" is simply part of the trademarked name, not officially standing for anything. The technology was developed by iBiquity Digital Corporation. The Federal Communications Commission selected HD Radio (a hybrid system in which digital signals are sent along with the analog carrier) as the standard for AM and FM broadcasting in the United States. FM stations can offer multiple channels (called "Multicast" channels) on the same frequencies allocated to analog radio stations . iBiquity Digital notes that the system approaches CD quality sound and offers reduced interference and static. As of July 25, 2007 , more than 1360 stations are broadcasting with HD Radio technology and more than 600 offering Multicast channels. Like traditional AM and FM stations, HD Radio programming is free, but a new radio is required. Brand name (Sony, Cambridge Sound Works, JVC, etc.) HD Radio receivers are available for home and car at major consumer electronics chains, online and through regional stores. ----- Original Message ----- From: "Alex Parks" <[EMAIL PROTECTED]> To: "Bob Cavanaugh" <[EMAIL PROTECTED]>; <[email protected]> Sent: Wednesday, September 05, 2007 6:11 PM Subject: re: [Braillenote] question about radio out of curiosity > What is it? > > Have a great day, > Alex > >> ----- Original Message ----- >>From: Bob Cavanaugh <[EMAIL PROTECTED] >>To: [email protected] >>Date sent: Wed, 05 Sep 2007 17:33:12 -0700 >>Subject: [Braillenote] question about radio out of curiosity > >>August 17, 2007 >>Dear list, >>I was just flipping channels on my radio a few minutes ago and >>heard a commercial for hd radio.
