The DAB module inside the Wavefinder is also designed by Roke Manor Research. If you're bored enough, you could in theory rip a Wavefinder apart and hack together a new interface for it. You'd have to be VERY bored though and have lots of free time considering most of the DAB decoding is done by the PC when using a Wavefinder I believe.
My Wavefinder has had about 2 hours worth of use out of it so far. There isn't actually any reception where I normally live!
At my proper home however, I can receive a Digital1 mux.
