I'd use a USRP2-to-host bandwidth of 250KHz.
You can create a simple FM receiver within GRC in about 10 minutes, since there's already an
FM demodulator block--although it would just be monophonic. You'd need more sophisticated
processing to do FM stereo--and I think someone posted such a flow-graph last week on this list.
The WBX card is tunable from 50MHz to 2.2GHz, so you should be easily able to tune the standard
North American FM broadcast band, and use a small antenna going into the RF port.
If your flow-graph is RX-only, I think the UHD code will use the TX/RX port by default for your
RX signal path.
