Thanks Thomas. Those are all good suggestions.
Michael,
The problem is twofold.
(1) You asked the 2.4 GHz daughterboard to attempt to tune to 101.5 Hz
> usrp_wfm_rcv_nogui.py -f 101.5 # should really be -f 101.5M
(2) There's a bug in the daughterboard code, that has it blow up
instead of just cleanly returning a failure code.
[Matt, can you please fix this when you return from Dayton? This problem
may exist for all the RFX boards.]
Also, the tutorials (like most everything) were written by a
volunteer. The underlying code base has changed since they were
written. Perhaps Dawei or someone else can update them if they get a
chance.
