    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.

    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?

    This one seems ok.

    ​​​​​​if you dont want to see continous output "lost at least xx bytes", use following command :

    rtl_test.exe -t


    ​​​​​​​.
    but I am facing this with this stick too,

    yousaf465:

    Dongle with wrong tuner chip "Fitipower FC0012".
    The Tuner chip should be Realtek R820T2.

    The two chips in dongle should be RTL2832U+R820T2, but your current one has RTL2832U+FC0012.

    Purchase another dongle with correct chipset.

    Hello Guys,

    after making the test i got this result:
    pi@T-LIRL12:~ $ rtl_test -t
    Found 1 device(s):
    0: Realtek, RTL2832U, SN: 00001000

    Using device 0: Generic RTL2832U

    more or less everything ok, but what does it mean "[R82XX] PLL not locked!"? How can i solve it?

    Many thanks!

    Hi,

    After windows ban trying setup Raspberry PI3 with Jetvision DVB-T stick. I have system running with 1090 Dump and FR24 feeder.
    But this system is deaf, I can have only 2-5 flights decoded one time max distance around 50nm. Same antenna with AirNav Radarbox will give 40-50 flights > 150nm.

    So maybe I have deaf DVB-T dongle?

    tested dongle:

    pi@raspberrypi:~ $ rtl_test -t
    Found 1 device(s):
    0: Realtek, RTL2838UHIDIR, SN: 00000001

    Using device 0: Generic RTL2832U OEM
    Found Rafael Micro R820T tuner
    Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6
    [R82XX] PLL not locked!
    Sampling at 2048000 S/s.
    No E4000 tuner found, aborting.

    Any thoughts?

    Xavier


    EDIT: Well, replaced Jetvision with Flight Aware ProStick plus and now getting ten time more flights, max distance >200NM

    This one is very nice: https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/

    You could even get their LNA if you want really good reception (rtl-sdr.com/new-product-rtl-sdr-blog-1090-mhz-ads-b-lna/)

    There are some dongles with integrated filter and LNA, those are an option as well. (external LNA is way better though)
    (airnav flightstick / flightaware pro stick plus)

    As you already have Pi Zero, use Pi zero's 5v adapter with Pi B for trial.
    Tried and my verdict is my sdr dongle is the fault even found an app for Android and tested it on there it gets scorching very quick 1-2 mins then stops sending data, dismantled it and back of pcb is discoloured under both of the main chips.

    This was a cheap and cheerful one from China and has lasted about 18 months any recommendations on another or do they all eventually burnout as I know they all run warm

    Hi my raspberry pi model b setup has been working well for year but just stopped, Iíve tried rebuilding, replacing pi for a pi zero w and an official 5.1v 2.5a psu and am wondering if my dvbt dongle has failed, the light on the dongle seems to go out or flitter like thereís a loose connection and it gets warm whilst making a high pitch noise.

    Iíll try troubleshooting over the weekend any recommended tips or ways to troubleshoot please.

    Iím convinced the original PI (model b) had an issue as running lsusb shows the dongle but after a time doesnít.

    Using the new pi zero w I have followed the steps above on it and get what looks like a good test:

    Does this mean my DVB-T adaptor is not compatible? Shall I give it up?
    I've highlighted the key factors.

    That is not a realtek based USB stick which is required. So no, not compatible.
