Not to make it personal, but AGREED. A bunch of press release big words that mean nothing.
The "HD" format is mainly being utilized by greedy broadcasters to put analog translators on the air via loopholes already discussed to death and to relay programming that already exists, like AM's being put on the HD subcarriers. (a waste of money...why not just make your AM sound GREAT and keep it's physical plant and marketing in the forefront of your broadcast operation?) Broadcasters using HD for translators rarely even mention the HD "parent" of their new 'station' meaning they're not pushing for sales of HD radios either. Come to think of it I've NEVER heard a translated HD station mention the "HD" side of the parent.
If someone gave me the license today for AM HD and the equipment, I'd send it back to them. Now that I have a vehicle equipped with it, I find neither the range nor the programming variety promised by this format. I'm also grateful that most AM's who tried it have abandoned it. Not only is the AM band quieting down a bit as HD goes away, but it has helped fuel the FCC's look at AM revitalization which they wouldn't have needed to start...... IF HD on AM had been a consumer "hit." Instead, the failure of HD is slowly fueling the talk of the return of better quality AM (analog) broadcasting. Unfortunately, most receivers in autos and homes are moving toward the cheaper end of the spectrum, and offering NEITHER HD options nor REALLY GOOD AM. Yet.
On the FM side, HD range is still an issue, in my case, 30 miles in either direction to at LEAST some 50kw stations with HD and it switches back and forth...sometimes BADLY sometimes almost like both arrive and are played simultaneously with horrible echo effects. Be it the broadcaster or the in-dash unit, either way, not a good result to the consumer.
The proprietary nature of the HD license is moving lower and lower on the balance sheet priorities of terrestrial radio, unless the HD is necessary for
the above uses of feeding translators. It is NOT growing. Go to a common consumer store that sells "average" auto or home equipment. You won't find HD at the front of the shelves. Probably not ON the shelf at all. Remember, figures can lie.....and ...well, you know the rest.
Sometimes companies buy other companies for their own purposes, hire P.R. people to use big words, and the truth is not known for YEARS down the road as to why the sale occurred...but the seller laughs all the way to the bank. I'd bet my money on that scenario here.
