Hi Bert,
I no not pretend to be fully informed of all the relative merits and
otherwise of the DAB+ versus DRM+ technologies. I understand though that
DAB+ may be better suited to multiplexed transmissions.
Apparently the intention is to bring out combination DAB+/DRM+ radios at
least in Europe and I believe down here also. I presume this about covers
the bets in this regard.
Perhaps a look at this website may be of use:
