According to a survey a month or so ago, almost 30 percent of US adults were having trouble paying for necessities.

What survey and what are the details?
I doubt many skip their booze and butts.

So might I ask what any of the discussion so far about AM Digital Broadcasting has to do with amateur radio operations on the 2200 and 630 meter (135 and 472 kHz) amateur bands?

No reply and no surprise either. Some dont like facts getting in the way of their spouting off.

You think everyone checks into this forum on a minutely basis?

Here's another link. The one third having difficulty is mentioned in the fourth paragraph.

Digital or not, the problem with HD AM BCB is lack of bandwidth.  There just is not much OF it on AM.  To support HD will require more bandwidth or a CODEC with lots of compression and minimal ECC, which means a very good SNR will be needed to receive it without VERY annoying atrifacts popping up.  Data caching to eliminate dropouts will be tough - not a lot of extra bandwidth to do it.

Cellphones have so much bandwidth in comparison that they can accept coded audio transmissions in bursts, cache them and then play back the material at a lower rate.  Most dropouts are simply smoothed over by the caching and ECC process, so reception stays pretty good for OTP music until the network data signal gets very bad.

Apparently you do since you are a certified troll.

Your links are a laugh also since they both belong to the Looney Tunes left.

No need to reply either as you are now permanently cataloged.

I gave you your answer and then you call me a troll. Nice one.

The links I posted include data from the US Census bureau when it was under a right wing administration. And right now the economy is in a downturn due to covid.

Carl:

"Your links are a laugh also since they both belong to the Looney Tunes left.  No need to reply either as you are now permanently cataloged"  (Etc.)

Still trash talking and throwing out veiled threats, I see.  Crude, rude and abusive, as usual.  Seems much more ... ummm ... "fringe" that anything RENTON said.  And after all that time locked inside to reflect, too.  I thought you'd mellow.  Maybe not.

So.  Why not just move on and let it be.  You two disagree over something that makes little difference - why make an issue of it.  There's no value proposition to it, for anybody.

This is being done to increase the amount of revenue for stations.

With digital, you can have multiple streams on each station.  Like digital terrestrial TV did for us.

Now, you can sell commercials to multiple "channels".  More sales = more revenue!

Nevermind the fact that radio is dying.  I work on multiple job sites and ONE person uses a radio.  He only listens to extreme right wing conservative talk shows.

Not one other person, out of the multiple job sites spread across the state use a radio.  The stream off their phones.  I admit, I do the same thing.  15 bucks a month and I don't have to listen to a single commercial.  When I don't have signal on the phone I can still listen to the music I've marked for offline listening.

As the radio listening public ages and dies, less and less people will want to even listen to AM radio.  It's a dying demographic.

Wonder what happened to the buggy whip manufacturers years ago?

Surely you might ask. No one is going to answer your silly question, but go ahead and ask.

I noticed when test driving a Tesla (did not buy) it has no AM and no SiriusXM. I live in Utah and when driving in the middle of nowhere, I like listening to something current. I have wondered if the EVs use switch-mode power supplies and the resultant RFI would make listening on AM impossible.

Why not address all of this to the FCC?  They are the ones who authorized the change!
And they DO listen to Congress.

Wonder no more.  YES, this is precisely the reason a Tesla does not have an AM receiver in it. That and the listening public have lost interest in AM broadcasting. AM radio is a dying thing. Kind of like land line telephony. Might not live long enough to see it gone completely, but it is going.
