[Hackrf-dev] Replaying a captured radio signal

[Jahn]

At https://greatscottgadgets.com/sdr/11/
there is tutorial how to use HackRF to replay a captured radio signal.
But how to capture the signal if I do not know the exact frequency?
Is it possible to set frequency interval there?
Any idea?
Thanks

You'll need to determine the operating frequency of your target device before
you can capture a signal. I discuss how to use information from the FCC to
determine the operating frequency in this video:

Another popular solution is to use qspectrumanalyzer with hackrf_sweep at close
range to the target device.
