Radio World guest column: Replace AM band with DRM on 45 - 50 MHz band

TheBigA said:
The FCC has already considered and rejected the idea.

And broadcasters have rejected any idea of a new band, as there is no way to get people to purchase new radios, replace all the existing car radios, etc., when the trend is to get entertainment from multi-function devices like smartphones, tablets, and expanded function dashboards in cars.

And an all digital radio service would likely open up a rights battle under the DMCA.

Smartphones. We saw how well it went trying to activate FM receiver chips. It didn't happen, as much as I hate to admit it. Then there's the pesky problem of the need for an external antenna for 88 -108 MHz, and an even longer one for 45 - 50 MHz.

Is the threat is that a new, all digital radio service would provide increased audio quality over the present,antiquated IBOC system?
 
Now to FBL (fantasy broadcaster league) mode: What about audio subchannels with ATSC 3.0? Granted there would need to be a token video component to transmit still images and be compliant.

ATSC 3.0 at UHF might have a chance to work on mobile devices, unless the cellular industry blocks it. (Likely, without regulatory intervention)
 
Sorry. It's likely to remain a fantasy.
Pulling audio from an ATSC 3.0 stream is complex. There is no simple way to do it. The process also tends to be a power hog ... that's why there are few, if any portable, battery powered HD TV sets.

No, the threat is that a pure digital service on a new band can not be positioned as a simple "improvement" to existing services and could require a new license agreement.

Exactly...the first word in the DMCA is "digital," so anything that is purely digital would require a new license agreement, covering labels, artists, writers, and musicians. The deal with the writers would be a different license from the existing ones with BMI and ASCAP, and the judge just approved a huge rate increase. Is the "improvement" worth the price?

I've had a Haier 7in portable LCD for a couple of years...battery life is fairly good

No video needs to be present...audio only channels are currently done on 8VSB...

But if the goal is to be carried on mobile devices, you can save a lot of work and money by starting an internet radio station.'

It's like recording an album on reel tape, and releasing it as an mp3. Why go through the expense of analog when it's just going to end up on someone's phone?
 
ContinuousWave said:
So wouldnt the proposal for ma3 all digital on the AM band also cause the same thing?

Yes, if the practice becomes common. For the moment, the one station that is pure digital is "experimental". But I am sure the recording industry is watching for any opening to go after broadcasters again.

So, in other words, it could kill all-digital AM if it starts getting off the ground?

Unless very special digital royalties are granted, the cost of rights payments similar to those for online would likely make it impossible for any ad-supported station to make a profit.
 
Sunset. Look at LW and Shortwave and MW in other than US. They are close to fading away completely, but as long as there is regulatory authority to transmit on the band, somebody will be there.
