spectrum, I have to wonder if anyone out there in their intended

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...

DRM as a Broadcast Media seems to Work Best out
to 3500 km ~ 2200 Miles which is a Natural for Radio
New Zealand's Over-the-Ocean-Area Broadcast Scheme.
