I'm just wondering if HD radio on the AM band is in their testing stages that they might be allowed to use HD on AM Radio 24/7...Does anyone have info. on this ?

Will HD on AM Radio Ever be Available 24/7 ?

I have heard that iBiquity is running their own biased tests, but the FCC pulled IBOC off its agenda on July 13th, for undesclosed reasons. As of now, thank God, the FCC has not approved IBOC for nighttime AM, due to the possibility of IBOC skywave propagation interference. Here is a good article, but I believe iBiquity was involved in the tests, so take it with a grain of salt. Maybe, the FCC should approve nighttime AM IBOC, just to see what a mess it would create:

The only remotely acceptable nighttime option will be to allow digital only broadcasts +/- 5 kHz from the center frequency in a fashion that wouldn't interfere with other stations...

I don't know what the FCC will do at this point. IBOC seems to work well during the day on a car radio - especially on blowtorches such as WLW and WJR. However, I am skepitcal on how IBOC will work at night on the graveyard stations. I'll bet that the digital signal will fail within 1-4 miles of the tower, depending on the level of skip. I agree with Audiophile in that IBOC should only be allowed at night in the all-digital mode. But the only way I see that happening is if HD radios reach some critical mass and a station owner goes out on a limb and drops the analog to broadcast at night. A more likely senario I see happening is, for example, is if the station broadcasts primarily on FM and simulcasts on AM, which in that case the station owner wouldn't be taking too much of a chance to drop the analog on AM. That is just conjecture though and it will be up to the FCC and general public.

Tom Ray is well known for his advocacy of IBOC. It solves many of his reception problems in the New York metro area. Unfortunately - the realities of New York City reception would be completely irrelevant in the Western 2/3 of the country.
Nighttime skywave is a valuable service for millions of Americans living in remote rural areas, or sports fans displaced from their home town. Its importance should not be trivialized, and its users not ridiculed and marginalized.

Speaking of Tom Ray, here is a quote by him from the AM stereo forum on the question of whether IBOC will be approved for nighttime AM:
"My sources tell me that as soon as the public service questions for the additional FM channels are settled, it's going to happen. Before anyone gets on their high horse with disparaging remarks, this came from two legal eagles close to the Commission and very reliable. They haven't steered me wrong in over 20 years."

If it is true, then the legal warfare will begin. Maybe that is a good thing. I can't say that I'm wild about having to live through the battle, but it might settle things once and for all. At worse case, some communications lawyers will get rich.dbdigital said:"My sources tell me that as soon as the public service questions for the additional FM channels are settled, it's going to happen.

I haven't seen Rich Wood on this NG for a while, but he advocated lighting everyone up at once to watch the interference wars. That would be too high a price for many small stations, but it would demonstrate whether or not this technology would work. I have serious doubts that "all would be well" if every station went to IBOC. It's the old "five pounds of stuff in a one pound bag," syndrome. But at least, we'd know, one way or the other.
