A question on the SNR measurements

Is there a "KiwiSDR SNR measurements for Dummies" citation that someone can share? I guess my first question is, why does my Kiwi always seem to display the same number for both?


Thanks for your patience and expertise.

    By "same" I mean both values seem to be the same. The number of course varies throughout the day.

    Perhaps answering my own question, I have built a 5 pole bandstop filter for the AM BCB, which , if the difference between the two reported SNR values is whether it does or does not include the BCB (as another cite seems to state)then makes sense.

    I measured the filter response with a VNA and there was almost 60 dB of attenuation in the BCB .
