In this new video, John Fallows, VE2EY describes how diversity reception works, & talks about how well the RSPduo performs for both signal enhancement and noise reduction over such a wide spectrum of frequencies:

 

The RSPduo is a true dual channel receiver which when used with SDRuno gives diversity reception.   It can also be used for real time antenna comparisons for example on HF when conditions are constantly changing.  It’s also great for monitoring two widely spaced bands of frequencies (say 80m and 2m amateur bands, or ATC and ADSB) as demonstrated in this video:
