Which daughterboard are you using?

I am using the DBSRX board. I have actually gotten the receiver
working more or less through trial and error, but I have yet to do the
FM demodulation in Python.
I put something together in GRC that uses USRP -> NBFM receive ->
file_sink, but I just accepted the default values as I do not
understand the meaning of the NBFM block's parameters.
