Thank you very much @TouchTheSky and @b3nn0 for your answers, it is very clear.

I will go have a look at Github discussion. 

While I'm here, I would like to take the opportunity to ask about what is the best way to reduce the OGN Noise. 

Looking on the screenshot below, I seem to be suffering from significant range loss: 5.31x. Is there any way to improve this?

Thanks a lot, and happy Holidays to all!

I assume you are using the usual antennas so you may try to move them away from your Pi as it is the source for most of the "noise". A good alternative would be a T style dipole antenna which usually comes with 1-2m cable. Sometimes all metal Pi cases help but then Wifi might become less reliable. Can you post a picture of your Stratux?

Btw, you may consider the Stratux Slack channel where many of us are quite active: Stratux Slack. Besides the "#general" channel there is a particular channel "#stratux-europe-edition".

Thank you for you answer. 

I will register in Slack. In the meantime, attached a few pictures. Sorry for the orientations, but for some reason the forum in turning them as it wants...

The Startux is on a GoPro mount, and has large 1090 and 868 antennas. It is mounted on the left side window of a C172  between the door and the panel. 

I identified some possible reasons, what do you think?

- the GPS plate is touching the SDR - but I dont really have a solution for that...

- I added a small cooler below the SDRs, as they seem to get hot - do you think that this can have an impact? Should I remove it?

Below the hood, I also have the Dross board with the Baro and AHRS sensor, as well as the off-button. I don't know if these can have any impact on noise?

Thanks!

This seems like a pretty standard Stratux, no immediate concerns. I would not worry too much about the 15dB OGN noise, it can have multiple reasons. Make sure that your antennas are oriented vertically.
