    That screenshot is not enough to diagnose. Please provide following info:
    1. Which OS image you have installed on your Pi, Flightradar24's PI24 image, or Flightaware's Piaware SD Card image, or Raspbian OS image?
    2. Which software you have installed on that image?
    I am running Homeassistant with MaxWinterstein's https://github.com/MaxWinterstein/ho...stant-addons's ADB-S Multi Portal Feeder, which is based on Thom-x's docker-fr24feed-piaware-dump1090's
    It was working fine until a few days ago. Now I am facing this.

      Your system is way different from the system most of the people are using.
      Is it installed on Raspberry PI or on a PC?

      I have no experience of such a system and cant help.

      Your Dongle has shown OK in rtl_test.exe, but dump1090-fa is not able to detect it.
      Dont know why, may be the dongle "pass-through" of your system is not functioning ok.
      Better use a simpler system, a Debian based OS, with direct install of dump1090-fa, fr24feed etc. These simple systems have much less problems than the system you are using now.

        Stick tested as expect, however I got the message: [R82XX] PLL not locked!

        Any suggestions?

        See below:

          Your Stick's test output shows it is healthy.

          Dont worry about "[R82XX] PLL not locked!". This is normal behaviour of a healthy Stick when tested.
