Diversity with ... a couple of RTL-SDR blog v4

[Roberto Brunelli]

Would it be possible to perform diversity noise reduction on a couple of RTL-SDR blog v4 using different antennas using gqrx? Any suggestion or link to tutorials?

Thanks,

Hi Roby

I would expect the first thing to do is find a way to synchronize both RTL to allow cohérent processing and noise reduction.

You could do that in hardware or in software if both rtl’s can receive a common signal that can be used as reference.

Cheers
