It's like the commission set out to destroy AM. They didn't have the balls to enforce the winning AM stereo scheme. They should have made anyone who submitted a system accept the FCCs decision as a condition to submit. FM stereo had standards that the FCC mandated.
Mexico adopted an AM stereo standard, but AM was already dying when that happened. No matter how much the government pushed, AM was dying. The biggest issue was part because the public did not want to spend on new radios as they already were listening to FM. And it was also in part because station owners did not want to spend money on AM which they realized was dying already no matter what.
Then the industry tried to monitize AM digital which doomed IBOC because the receiver manufacturers were not offered it for free.
Who would have paid for for the receivers if not the manufacturers who wanted to sell them at a profit?
Example: replace every car radio, about 250,000,0000 of them, at a cost of perhaps $75 t0 $100 per car with very cheap radios and labor... that would be at least the double of radio's gross billings per year back then! And not including home and work radios.
Had there been a fleet of car receivers and the FCC made everybody go IBOC at a set date it might have worked. I believe digital would have helped with static.
If you analyze AM stations in the bigger (rated) markets, you see that about 90% of them don't have a full market signal day and night to begin with. Spending on them is like dressing a hog in a ballroom gown: no matter how much you spend, you can't make those stations viable.
I keep on hearing the "marketplace" solution. It doesn't always work in industries that have been regulated heavily in the past. The Texas power grid failures a couple of winters ago proved that.
In the case of AM, start with daytimers. That class of service should never have been authorized. Then those stations that are so directional that they miss huge parts of their market. And stations in such small markets that there is no longer enough local business to sustain them.
I don't know how many AMs are on the air still just to sustain a translator. If translators could stay on and close the AM, I'll bet 2000 or more AMs would be off by tomorrow.
Look at El Salvador: of 42 AMs, either 5 or 5 are not religious. And at least 4 of the 5 are simulcasts of major FM stations that are sort of "heritage" stations. Yet 40 years ago, there were about 80 stations, all with adequate power and fulltime and none were directional. Yet, despite all that, FM swallowed them alive.
IMHO Digital AM radio might have kept AM viable and extra 10 or 20 years maybe even until the Internet kills off OTA radio. Would it saved every small town operator dealing with big box retailers, to survive, I doubt it.
While we waited for old cars to become junkers, you'd have a a decade where not even half the cars had digital AM, and even more before folks got new kitchen or home radios. In the meantime, who pays for the cost of running those stations?
In typical FCC fashion they left all of radio really vulnerable to the Internet.
HD radio was born of the fear of satellite radio, not of the internet. HD began development in the 1980's, long before the internet was even much of a dream.
When the commission moved OTA TV into the digital age thanks to the cell companies. They should forced all radio to transition over a 20 or 30 year period mandatory digital delivery too.
Viewers wanted high definition TV and would pay large amounts for it. There was no demand for slightly better AM radio back around the 80's when 75% to 80% of listening had moved to FM and there was no need for "improved" audio on AM signals that, mostly, did not give fulltime full market coverage to begin with.
TV analog Channel 2 thru 4 weren't the best channels for digital TV. All radio stations could have had a channel. IIRC channel 2 thru 4 were about 12 mhz of spectrum. Divided by 10 khz that's 1200 channels 5 khz wide. Class A & B AMs would have got class C or B FM height. C and D AM, FM A and FM HD subchannels and gets class A FM height. A 5Kz channel can easily do 56 k one way using the old dial up digital compression scheme. I am sure there are better digital compression schemes but whatever they used should have be "open or free" for receiver manufacturers.
You are creating a scheme to fix AM radio at a cost many times greater than a decade's worth of gross AM radio billing.
All folks who post gleefully about radio's shortcomings get ready. You can soon celebrate the dimise of WBT AM. You will get to post negatives about one of the few AM stations that still could be viable for a decade at least. I believe it will be the first Class A AM and the first 3 call letter "W" station to have it's licence surrendered this Century.
Remember, in the average rated radio market, only about 5% of listening by people under 65 today is to AM.
Urban One is stupid. They should have kept WBT AM as a flanker to their FM Republican Talk. Is the one time land profit going to offset the multiple year revenue lost if someone puts iHeart's national talkers on a decent Charlotte signal?
We don't know their plans. Remember, WBT has such a bad night signal that they used to have a 1kw "repeater" to the west of downtown just to cover an area that the original facility just does not cover.
