We are beginners using the USRP1 with WBX v.3 50-2200 daughterboard and GNU
radio Companion version 126.96.36.199 with UHD_003.008.000-18-g864f84b5 installed
on Ubuntu 14.04 LTS operating system. Our goal in using these is to create
an SDR WBFM receiver.
We have followed what was done in the video posted by the ettus research (
but have encountered some problems. As we ran the GRC file, both the fft
plot and scope plot appeared but all we could hear are static sounds
together with the script shown below:
Executing: "/media/thesis/Data/Downloads/Thesis/FM Reciever using
linux; GNU C++ version 4.8.2; Boost_105400; UHD_003.008.000-18-g864f84b5

We are hoping that you could help us with this problem. Thank you.
