We don't have XM, only DAB, FM, AM & LW
DAB is a no go as it's difficult to build the interface to it.
Dlink FM is unusable, well in my setup anyway.
SharkRadio may be an option if it's available in the UK and PC drivers become available (currently MAC only).
PCI cards - what is supported by MediaCar/Radiator? Which card has good FM reception.
