yes, I am afraid you are assuming all of us are as smart as you on the
topic so if you have time please have another go at it. You are in a
unique position to do this since you have all the equpiment at hand.
The thing that confuses me is why is it during the sweeps due the fft look
so different in each of the windows and it seems like the timing of the
sweeps are different. The sweeps happen at the same time for each dongle,
right? The dongles are all listening in parallel at the same time? If
so, seems like they would look more alike at the same time. My apologies
for the density on this end.
