Hi all, I'd like to know if there is a way to create a program, with GNU Radio Companion, which can acquire an unknown signal and display it on a FFT Sink, which should auto-calibrate on the right value of the signal. To explain better: I want to acquire a signal, but I don't know its value (Hz); so I need a FFT Sink that can do an auto-calibration, according to the value of the signal, to show me what the hackrf is acquiring, without having the issue to set the sample rate of the FFT Sink to an huge value to cover all the frequencies (difficult to visualize). Thanks for the support
