Seeking Assistance with Data Upload Issues to Flightradar24

[Cas Meutstege]

Hello forum members,

I hope you can help me with an issue I'm currently facing. I am new to this and struggling to successfully upload data to Flightradar24.
Here are a few summaries and logs from my attempts:

I am aware of my limited experience in this matter and am very interested in your insights and suggestions.
Are there specific steps I might be overlooking? Or are there settings I should adjust?

Any form of help or guidance is greatly appreciated. Thank you

The tuner.type is the important bit.

Thx for your reaction! i get this error back: pi@pi24-bookworm:~ $ rtl_test -t
Found 1 device(s):
0: Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM

Failed to open rtlsdr device #0.

You need to block all services accessing it first.

Thats where all the stop fr24feed, stop dump1090-fa, stop dump1090-mutability etc comes in at step 2.

Something was not run there

i did rtl_test -t with output: Found 1 device(s):
0: Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM
Found Fitipower FC0012 tuner

Sampling at 2048000 S/s.
No E4000 tuner found, aborting.


and with rtl_test i did get:

Info: This tool will continuously read from the device, and report if
samples get lost. If you observe no further output, everything is fine.
