Thanks for the help. I actually got *simple_ra_receive*r to work. All I did was remove the gr-osmosdr folder from where all the other gnuradio GR folders are and reinstall it. Also I noticed that to make it run I had to use the terminal and type the command *'simple_ra'* and not use the grc flowgraph. Is this always true?
Anyways thanks for the help again. On Wed, Oct 19, 2016 at 2:17 PM, Marcus D.
