I wonder what's going on with DRM ... Is anyone broadcasts seriously, or is it just some curiosity?
Never really got off the ground, although there's a few broadcasters transmitting it and a few mad enthusiasts running around shouting "it's still good, it's still good!". Pretty much every country in the world has trialled it; pretty much all of them have given up. The DRM Consortium now seems to pitch DRM by poking it with a stick and saying "look, it's alive! And here's a bunch of receivers that haven't been manufactured in years to receive it!"
And then there's India who, after seeing a few presentations from the DRM Consortium, got all enthusiastic and upgraded all their AM transmitters with the aim of kickstarting local receiver manufacturing & cutting over to DRM in 2017. Let's just say that's looking increasingly unlikely. Similarly Pakistan, not to be outdone, recently announced they're planning a conversion to DRM+ (the VHF version of DRM30). That's unlikely to happen either.
No portable receivers (the last one, the Indian Avion AV-DR-1401, despite still being featured on their website hasn't been available for months). 2 allegedly in the works, but I suspect at least one of them (the Gospell GR-216) will never progress beyond a few demo units. The other - the PantronX Titus II, made in conjunction with the Christian shortwave broadcaster TWR - at least looks interesting, since it's a portable radio based around a tablet running SDR software with a DC-to-2GHz tuner...
But currently if you want to buy a DRM receiver you have to go to India and buy a Hyundai i30 compact car, or a Hyundai Tucson or Mahindra TUV300 SUV...
