If a station was on the lower frequencies, below 500 kHz. and digital only,
there would probably be enough bandwidth for full response audio. The
digital would be on the main carrier of the LF transmitter the analog would remain
on the MW carrier (No IBUZ). Similiar to what is being done in Europe
with DRM.
Now lets see if there will be a rush to buy Blaupunkt car radios??

The antenna bandwidth "down there" starts to get "iffy"
as you go lower and lower in frequency (below 500 kc).
So there would be a set of compromises between
upper-end audio limit, operating frequency and tower
height. I'm not saying not doable but there would be
some problems in those areas.
