[Discuss-gnuradio] Signal drought

[Greg Hulands]

Hi,
I built all the code today using the build-gnuradio script and when I create a 
simple GRC flow graph going from the USRP source to the waterfall plot, I get 
no data coming in. I then built gqrx and ran it and it too doesn’t get any data 
in from the device to display on its waterfall. I ran the rx_samples_to_file 
example and captured some data, but when looking at it in a hex editor, it 
doesn’t look like it captured anything in particular 
(http://test.utr-software.com/sdr/rxdump.dat). I ran it with 
./rx_samples_to_file —freq=107700000 —rate=1000000 —file=~/rxdump.dat.

I am new to gnu radio and sdr so I’m not yet sure how to dig in to debug these 
issues.

Anything help is greatly appreciated.

Thanks,
Greg
