Hi Guys,

I'm looking for an FM module which can feed the received signal back to the Arduino in digital form
for processing.
I realize that I could take an analog out board and route it through an A2D converter but that seems like such a waste when the signal already exists in digital form inside the receiver.

Id also like it to be relatively inexpensive in bulk.

DAB/DAB+ would be nice but not essential.

Any pointers to a chip to do this, hopefully already mounted on an experimenter board?

Are you referencing a commercial FM broadcast? If so, their signal is several hundred kilohertz wide. Would take a lot of computer power to digitize that.
