Here is a good site about the DRM farce:

"Digital Radios Australia"

I read that the DRM scammers are working with the iBiquity scammers.
DRM for SW seems about as dead as AM-IBOC:

"Why don't you use DRM on Shortwave?"

"Some large companies are pushing DRM by convincing program producers
and broadcasters to start airing in DRM ahead of time, but unless
there is mass availability and penetration of receivers on the
listeners side, this will remain - unfortunately - a technological
experiment, and broadcasters using it to reach their listeners now,
are clearly throwing their money out of the window."

Of course the DRM Consortium, just like with iBiquity, won't admite
that their technology is dead. Wow, only about three very expensive
DRM receviers available, and HD radios are being pulled from store
shelves, and in-dash HD radios are moving to only "HD Ready".
