I listened to that podcast. The FCC should allow individuals to broadcast from 1620-1700 Khz AM Radio is Dying. with at least 5 Watts TPO or consider 6.9-7 MHz for Hobby Broadcasting.
With Today's technology NBAM, NBFM DRM you could have several channels.

I think one reason failed to make a dent in North America is the unfortunate connotation with the phrase Digital Rights Management in this country.
The great radio thought-matician Carl Blare has said that HD Radio amounts to a form of encryption, a digital rights management, since you need an authorized, proprietary chip in your radio to decode it.
Even the DRM Digital Radio Mondiale standard is owned by companies and not truly open. It offers a barrier of complexity, where the strength of analog radio is its utter simplicity, just needing a few simple parts to hear broadcasts.

Also, analog can't be patented. Anyone can make a transmitter or receiver. That's why a part 15 digital transmitter will never be. Procaster or Rangemaster or Talking House will never have a digital version. We need analog for our hobby.

I always thought a different band should be used for digital broadcasts, as European countries have done for many years with DAB, Digital Audio Broadcast. Even that hasn't had the greatest outcome, since when it got established with a large number of radios that could receive it, the government had an excuse to start shutting down analog AM and FM services. Here in North America, since we have digital ON the AM/FM bands, even in a most clumsy way, it may help to preserve AM-FM analog.
Another problem with digital broadcasting is multi-casting, where a station gets a certain bandwidth, which they can use for one station, or split it into several streams. It sounds great to have more stations, but then the audio quality suffers from having a lower bit rate for each. Because broadcasters want dominance and to capture more ears, there's a big incentive to split the bandwidth into as many channels with a quality that radio operators believe listeners would still be able to tolerate, and you get a sound that is only suitable for casual listening, not high fidelity. The sound quality ends up being no improvement over AM or FM.
Anyone who has SiriusXM satellite radios probably knows how this works, some specialty channels are given higher bandwidth, like Howard 100 and the Grateful Dead channel, where other music and talk channels have sound that's like listening through a tin can.
The latest Radio Survivor show has more about 'those' stations that Mark was referring to, including sound bites that make one feel more sympathetic to the stations, run by real people.
