Hi Cinaed, Thanks for your answer.
Do you mean that depending of what kind of signals you want to detect it might be worth to use sample rates below the minimum recommended? For example, to look for GSM channels (BW=200kHz) I should use a lower rate? When I first asked the question I said that the lower limit is 8MHz because I read it somewhere a long time ago, but after sending the message I was looking at the specs again and I saw that the minimum supported sample rate is 2MHz (here: https://github.com/mossmann/hackrf/wiki/HackRF-One [https://github.com/mossmann/hackrf/wiki/HackRF-One]). Which one is the real minimum? Marc.

The sampling rate depends upon the problem. For instance, using a 8 MHz sampling rate to listen 16 kHz signal is overkill. No, the pi can't support high sampling rates. Even the Raspberry pi3 is to slow to run an SDR and the HackRF and do anything useful - except possible capture signals directly with the HackRF. And even then writing to microSD card may limit the sampling rate.
