I find myself disoriented after reading your response. The AM/FM BC notch filter of the RSP2 is software-selectable but I though it was an 'actual' filter, not a 'software filter' (DSP filter ?)... The RSP2 FM filter is specified as providing >60dB on the range 80 – 100MHz. So I understood it is use...

I live close to a very strong FM station. I normally use the RSP2 notch filters to prevent interferences. I would like to activate these filters when using dump1090 but it seems there is no option to activate them. Thus I have to use an inline FM filter with the RSP2 which is a bit weird. Am I right...

Sorry, I forgot, there is also an option to enable BiasT. So I assume it is not activated by default (try --help)

There is an option to use portA.
You can check it doing on the command prompt.
The option is You can add the option to the .cmd file you use to start dump1090
