Re: [Discuss-gnuradio] Getting overflows at 50 Msps (not sure why)

[Orin Lincoln]

I appreciate the suggestions I received. It turns out that I was able to 
run GNU Radio with realtime priority, and that solved my overflow 
issues. I am now able to run flowgraphs that actually do things without 
getting overflows all the time.

Thanks,
