Thanks Vince
I found in rtl-sdr. rules a rule corresponding to my SDR stick :
SUBSYSTEMS=="usb", ATTRS{idVendor}=="*0bda*", ATTRS{idProduct}=="*2838*",
ENV{ID_SOFTWARE_RADIO}="1", MODE="0660", GROUP="*plugdev*"
I added the weewx user to that group: "sudo usermod -aG plugdev weewx"
I still can start weewx with the "sudo weewd" command as before but I
can't run weewx in daemon mode. "sudo systemctl start weewx" gives still
the same error :
