[Hackrf-dev] HackRF Hang while Tuning with GQRX

[Russell Hande]

It went pretty fast! I have an i7 3770 myself. I didn't time the
actual process of going from 88 to 6GHz, I just ran the script with
the linux 'time' command. It looped around about 5 or 6 times. I
wasn't watching it 100% of the time, sorry.
