It was selected by the U.S. Federal Communications Commission (FCC) in 2002 as a digital audio broadcasting method for the United States,[1][2] and is the only digital system approved by the FCC for digital AM/FM broadcasts in the United States. It is officially known as NRSC-5, with the latest version being NRSC-5-C
As a standard practice, the kilohertz signal rate is written next to its corresponding data transfer rate kilobits/s or kbits/s in HD Radio documentation. While HD Radio does allow for an all-digital mode, this system currently is used by some AM and FM radio stations to simulcast both digital and analog audio within the same channel (a hybridized digital-analog signal) as well as to add new FM channels and text information. Although HD Radio broadcasting's content is currently subscription-free, listeners must purchase new receivers in order to receive the digital portion of the signal.
As of May 2009, there were more stations in the world on the air with HD Radio technology than any other digital radio technology. More than 1,900 stations covering approximately 84% of the United States[4] are broadcasting with this technology, and more than 1,000 HD2 and HD3 multicast channels are on the air.
The differences between tube amplifiers and semiconductor ones is in the design not the device used. People can and have designed semiconductor amps that have exactly the same behavior as a tube set. There appears to be no significant market for such an amplifier again implying tube amps are a rich guys toy...not a better device.

You keep on repeating your opinions and me mine. I can buy a vintage tube amp pretty inexpensively. Better is purely subjective.

No it is not. Audio quality is quantifiable. Even yours if you wished to spend the money. There are amplifiers with identical audio properties made from tubes and from semiconductors. People buy the tube versions for reasons other than quality. If you wish you can buy old semiconductor amplifiers for practically nothing. So you and others buy these tube devices for reasons that are not related to audio quality

I've never bought one. The sound is indeed different though.
That's not the case at all. With analog when you have poor reception you can watch a fuzzy picture, not sure why you would want to do that. With digital it's all or nothing. What you need is a better antenna, this is not a new problem. Large antennas on the roofs of most houses were common until about the 70's, some of them could even be remotely moved mechanically.

You claimed I was wrong but then supported my position. A fuzzy picture does still beat no picture. Digital doesn't travel as well as analog.
I think it's a bad idea, they should keep both. Airwaves can be used when the **** hits the fan easier than digital.
