This is, from the description, a remarkable product. It is not a radio but rather a means accessing sound files stored on a micro SD card. The suggested contents (which include two episodes of The Archers) are an eclectic mix of bits which can be used to simulate random radio tunings. The documentation references the team radio works of John Cage in particular.
If I fail to make one, I'll try to bribe someone to do it for me.
It should complement the ADDAC FM Radio.
