DRM in a hybrid mode also has the same fault as IBOC, but not as bad. DRM on shortwave is a bandwidth hog, and if you don't have a VERY strong signal it doesn't decode. ANY analog interference kills the DRM on the spot. It's more robust than IBOC in this respect, but not an awful lot better. And I expect neither IBOC or DRM in all digital mode on a an old graveyard frequency (for those who don't know...1230,1240,1340,1400,1450 and 1490) and 200 some stations on EACH of these frequencies.....ah I don't expect decoding more than a few miles at best.
