No DAB is supported by Centrafuse right now it seems.. I just started to look into DAB radio myself as I just got a FM USB dongle and wasnt too happy with the quality. And they started to get pretty good coverage in Norway
I saw another thread over @ flux media, and David was asking for a SDK for a DAB USB dongle, so im gonna try to get hold of one. According to worlddab.org there are 500 million people with DAB coverage, so I guess more people want this
