[Hackrf-dev] HackRF Hang while Tuning with GQRX

[Russell Hande]

Sorry, I meant 30MHz to 6GHz.
With the FFT on it takes 2 minutes 20 seconds for one cycle.
With the FFT off it takes 2 minutes 18 seconds for one cycle.

That said, it did crash once. But it seems to be the exception rather
than the rule for me.
