Thanks for the info.
It's about time they got away from this IBOC garbage.

But with DRM you loose your analogue audience, since it is digital only.
So for a long period of time you need 2 frequencies and 2 transmitters
at least per channel! Impossible on AM, and SW broadcasters will have a
hard time with these "double costs" for a long time.

What should be done is developing a system wich can simulcast analogue
and digital on one channel, without the disadvantages of the present
IBOC system. DRM could form the base for this.
This new system then can be used world-wide and on all AM bands! (SW,
MWorAM and LW in Europe and Asia).

The current hybrid AM/digital IBOC system is supposed to be transitional.
The IBOC receivers are supposed to be capable of demodulating the hybrid
modulation and a full digital modulation standard. Of course, the
transition to full digital won't happen until the broadcasters think there's
a high enough percentage of IBOC receivers in the marketplace. That won't
happen anytime soon, if ever.

I can't see why any US MW broadcaster would have any interest in DRM, even
if the FCC allows it.
