I have one of those orange FlightFeeder and also my own Pi. On both devices, I had to adjust the gain from the default AGC (-10 value) to something lower, because of the proximity with the airport. Lots of strong signals close-by will overload the receiver.
In the “Radio” menu, you can see the number of “clipped” messages in the past minute (and more). You can lower that number, by adjusting the gain in there.
Note that there is a software quirk there - once you have selected the new gain (tapping or dragging the slider) and hit “Apply”, the screen will be stuck there. Wait 10 seconds and hit “cancel”, it will bring you back to the previous menu, and the setting will be applied. Wait there a little bit and see the number of messages/second - if they are higher, then all is good.
You can go back to the status screen and it will show again the clipped messages (after 1 minute). You can’t go all the way to zero, but at least you should not have thousands there.
If you don’t feel like this is clear, please contact the FA support email listed on the box.
Also, install the filter inside the house, before the receiver, if they provided you one.
The pics below are taken at 6AM, at my location. Don’t pay attention to my Gain, I just slide it all the way to zero for this demo. Note that the “Max Gain” is un-ticked (that is the AGC setting).
