Hi Scott,

I just copied that code and ran it and I got a divide by zero error. It comes from

form.quantized_slider_field(parent=self.panel, sizer=hbox, label="Gain",
                                      weight=3, range=self.u.gain_range(),
                                      callback=self.set_gain)

range gets set to 0 and then somewhere in form.py it divides something by range to make the slider.
Any idea why this is happening? I know I can just assign a gain, but I think whatever is causing this problem may be causing me other problems.

Can you see if you get proper audio out, when you specify the gain as a parameter:

$ ./usrp2_wfm_rr_rcv.py -e eth2 -f 104.1 -V 0.0 -g 31 -O hw:0,0

It would be useful to know if your WBX board (assuming that you're also using one) is working correctly, and if my board has some sort of defect.

Best regards,
