Link to: HD RADIO™ GOES THE WAY OF THE LASERDISC PLAYER.

An interesting take from a non-broadcaster that gets it mostly right.    The premise for HD radio™, as the author states, was to serve two purposes; improve sound quality and add extra programming channels.  I have a few issues with this statement:

Regarding the improved signal, that still holds true, and can be especially beneficial for AM radio, which has struggled for some time with signal degradation.

I would argue the opposite. HD Radio™ has done nothing to improve the signal quality of the AM band. It has, in fact, degraded the band further by adding digital hash to adjacent channels, limiting the on channel analog bandwidth to less than 5 KHz and creating on channel background hiss.

Thus, HD Radio™ has done neither of those two stated goals.  In addition to that, from the radio station owner/operator’s perspective, it is expensive to install, expensive to license, expensive to operate and has no audience.

Hat from here.

...radio was discovered, and not invented, and that these frequencies and principles were always in existence long before man was aware of them. Therefore, no one owns them. They are there as free as sunlight, which is a higher frequency form of the same energy.
