      Hi everybody

      I´m having problems while trying to use rx_power on my Raspberry Pi4 with the SDRplay image V0.6 installed.
      My RSP1 is regularly seen by the system:

      >lsusb
      Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
      Bus 001 Device 006: ID 1df7:2500
      Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
      Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

      The problem is that after launching the command rx_power to scan the spectrum I often get a “Segmentation Fault”.
      Sometimes at the very beginning, sometimes after 1 minute or so.
      In very rare cases I could finish the 10minutes scan of a portion of the spectrum.
      I use this command:

      ./rx_power -f 920M:1100M:200k -c 50% -e 10m -g 30 -R 10 -S 5000 > scan.csv

      Note that the options -R 10 -S 5000 should avoid this problem (seen in a different forum) but this does not eliminate it completely.

      Does anybody had this kind of issues?

      Help appreciated.

        yeah had this problem with SDRPlay with any program back since 2019, both on a rpi 3, 4 and desktop machines. never resolved.
        if you keep an eye on dmesg you’ll see kernel taint errors before it will eventually die.
