IMHO - Both DRM for International Shortwave Broadcasting
and the USofA version of AM and FM IBOC are still in the
"On-the-Air" Stage of Development.
..
- Lets say that it will take three-more-years until one-third
of Broadcasters are actually Broadcasting in these 'new modes'
of broadcasting.
..
- Lets say that it will take three-more-years until one-third
of AM/FM/Shortwave 'portable' Radios have DRM and IBOC
features actually Built-into-the-Radios; that do not 'require'
some external processor to hear the programming.
..
- So IMHO - "Hold Your Breath" for 'three-more-years' or . . .
Buy the Best AM/FM/Shortwave 'portable' Radio you can today
and Enjoy three years of Broadcast and Shortwave Listening.

Since you mentioned that you have a Sony 'portable' Radio.
Check-Out a new Sony ICF-SW7600GR; a used Sony ICF-2010;
or 'think big' and take a look at the Grundig Satellit 800
Millennium. Enjoy your Radios )
