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
