Hi Simon,

FYI, I am including a link to a post that describes what has been done by oh7aeg (using 4 channel Afedri): https://github.com/AlexandreRouma/SDRPlusPlus/discussions/585
Me personally, I am interested in stereo diversity reception but it seems there are multiple applications of having a coherent multi-channel receivers.
Of course, one can't do everything at once, but at least something to keep in mind when beginning to implement multi-channel support.

Cheers,
