HI José,
>From your previous writings I understand that you describe yourself as the
"real hard core SDR operator" ;-))
What is the SDR Radio you are using in contests?
So far none of them is useful for contesting in Europe without sophisticated
preselectors.
Then you are saying:
"and then fezzing the panadapter screen, it is very easy just looking at the
width of the trace (small width small signal, wider width bigger signal)"
How is that possible?
Usually the width of the trace shows the transmitted band width, not the
received field strength.

Steve N2IC asks a very pertinent and interesting question?
"How seeing 200+ unidentified panadapter blips on a crowded band helps you
to identify non-duplicates and multiplier stations when you are running at
an average rate of 153 QSO's per hour for 48 hours."
There are a lot of nuances in the answer, and even though I don't pretend to
"educate" or have the stature of N6TJ's Secrets of Contesting Chapters that
I very much enjoy reading, I'll try to be a bit presumptuous and say my
explanation fits that Chapter.
First it is not a blip but a trace. By being a trace you have history. That
is you see back in time. If you are just an SO2R generation operator either
you are on the 500hz channel at the same time the possible DX is TX and you
listening to it or you are not and you listen nothing. With a panadapter you
see a signal trace. I set the motion of the traces on my panadapters to be
visible on the screen for about 20 seconds.
