Default DRM and shortwave

I don't doubt that DRM has certain advantages over AM/SSB transmission
on HF frequencies - but as I listen on my conventional radio to
transmissions of this mode from stations such as Radio New Zealand,
and the obnoxious sound it makes across a 10 kHz wide piece of the
spectrum, I have to wonder if anyone out there in their intended
service area is actually using this mode. I guess I can imagine a few
folks in East Asia who may have these receivers, but across the
islands I cannot imagine they are common at all. Does New Zealand do
this to reach better into the Asian interior? To antipodal Europe?

DRM's 10kHz wide signal is preferable to the 30 kHz wide IBLOCK mode
used on the AM band.

Still, they are not as obnoxious as CRI, who insist on plugging up
every other frequency with a transmission 24/7, covering up dozens of
other stations who now have no hope of being heard as a result...
