7 months ago I found the solution: in /etc/udev/rules.d need to be placed a file sdr.rules with the following content:
sdr
SUBSYSTEM=="usb",ATTRS{idVendor}=="0bda",ATTRS{idProduct}=="2832",MODE="0664",GROUP="weewx" SUBSYSTEM=="usb",ATTRS{idVendor}=="0bda",ATTRS{idProduct}=="2838",MODE="0664",GROUP="weewx"
the weewx group needs the permission to access the rtl_sdr-stick in usb.
I ugraded my weewx with sdr from 5.00 to 5.02 which has been working for two years without any trouble. After the upgrade weewx won´t start anymore with the following error:

So I tried a fresh install from Scratch and the same error appeats after switching from Simulator to SDR.
in syslog i found the following error (sam in old station and fresh install): 2024-02-12T12:06:40.861296+00:00 weewxN weewxd[24795]: INFO weewx.engine: Starting main packet loop. 2024-02-12T12:06:40.862126+00:00 weewxN weewxd[24795]: ERROR user.sdr: rtl_433 version 22.11 (2022-11-19) inputs file rtl_tcp RTL-SDR SoapySDR 2024-02-12T12:06:40.862354+00:00 weewxN weewxd[24795]: ERROR user.sdr: Use -h for usage help and see https://triq.org/ for documentation. 2024-02-12T12:06:40.862648+00:00 weewxN weewxd[24795]: ERROR user.sdr: Trying conf file at "rtl_433.conf"... 2024-02-12T12:06:40.862894+00:00 weewxN weewxd[24795]: ERROR user.sdr: Trying conf file at "/var/lib/weewx/.config/rtl_433/rtl_433.conf"... 2024-02-12T12:06:40.863187+00:00 weewxN weewxd[24795]: ERROR user.sdr: Trying conf file at "/usr/local/etc/rtl_433/rtl_433.conf"... 2024-02-12T12:06:40.863436+00:00 weewxN weewxd[24795]: ERROR user.sdr: Trying conf file at "/etc/rtl_433/rtl_433.conf"... 2024-02-12T12:06:40.863677+00:00 weewxN weewxd[24795]: ERROR user.sdr: Registered 191 out of 223 device decoding protocols [ 1-4 8 11-12 15-17 19-23 25-26 29-36 38-60 63 67-71 73-100 102-105 108-116 119 121 124-128 130-149 151-161 163-168 170-175 177-197 199 201-215 217-223 ] 2024-02-12T12:06:40.863962+00:00 weewxN weewxd[24795]: ERROR user.sdr: usb_open error -3 2024-02-12T12:06:40.864207+00:00 weewxN weewxd[24795]: ERROR user.sdr: Please fix the device permissions, e.g. by installing the udev rules file rtl-sdr.rules 2024-02-12T12:06:40.864458+00:00 weewxN weewxd[24795]: INFO weewx.engine: Main loop exiting.
