[Hackrf-dev] Auto-calibration in receiving mode

[Matteo Terzi]

​Hi Dominic,
What I'm trying to do is:
​- I want to acquire a signal from a general device ( garage door opener
remote control, rf car's key etc). So I don't know the real value of the
signal (2Hz or 40GHz). Is the hackrf able to set itself on the right value
of frequency and let me know the result by means of a graphic. I wanna use
it as a sniffer/reader of frequencies.

Thanks for the support
Matteo
