When nighttime AM-IBOC becomes reality, and the FCC has given HD in general its blessing, what on Earth are you going to do with your free time?
We'll probably:
1) Watch with interest as the stacks of receivers gather dust in the stores, due to lack of demand, while the 800 million analog receivers in the US continue to grow in number.
2) Watch with interest as broadcasters start turning off IBOC when they discover it's neither making them the boatloads of money they were promised, nor is it bringing back the listeners they've lost to other media, nor does it cover the same land area as analog, nor is it the high quality signal they were led to believe.
3) Watch with interest when broadcasters realize that there's no economic basis for doubling or tripling the number of FM signals in each market. It's so sad that broadcasters apparently learned nothing from the FCC Docket 80-90 debacle, because they are determined to make exactly the same mistake all over again.
4) Watch with interest as the AM band rapidly becomes utterly useless, due to everyone's signals spitting buzzing carriers into everyone else's signals...not that there isn't already too much noise in the AM band; running digital carriers well into the first adjacent channel (the IBOC spec for AM shows the primary digital carriers at 9.6 to 14.7 kHz away from the main analog carrier) will just be the final nail in its coffin.
Then, we'll probably be disgusted at the massive, wasted investment of time, energy and money into something which has proven to be so enormous a failure. It's nothing to gloat over. It's just sad and wrong.
