Hi,
auf der Suche nach Informationen über den QCX in Verbindung mit WSPR bin ich auf Maxwell Moran, W3LLA aufmerksam geworden. Der OM (sollte besser YM schreiben) ist 15 Jahre alt und macht tolle Forschungen im Bereich von Kurzwellenausbreitungen, Einfluss von Antennenhöhe auf die Reichweite von Signelen etc.
Er hat seinen QCX umgebaut, dass er auch WSPR hören kann trotz CW-Filter (
Alleine in diesen beiden "Büchern" steckt total viel Wissen von der Materie:

Sehr lohnenswert und es würde mich nicht wundern, wenn das mal ein K1JT wird 
"Why
should anyone bother with Amateur Radio in an era of smart phones and
internet based voice, video, and data communication? Why would anyone
want to use a radio and a large antenna to contact Europe or
Australia when you can just access your WhatsApp? Why is amateur
radio of interest to me? For me, there is something almost primal
about amateur radio. I find it fascinating that with a simple copper
wire and a homebrew transmitter, I can bounce a signal off of the
ionosphere and reach stations thousands of miles away, such as
Antarctica. Radio waves can even be bounced of the moon and travel
back to Earth. I compare the allure of Amateur Radio to the thrill of
sailing the seas on a sailboat using wind power alone. Similarly to
amateur radio in communication, sailing boats are no longer the
primarily source of transportation. Yet, when we watch yacht races or
spot a schooneron the horizon we are mesmerized by the majesty and
mystique of its massive masts and sails full of wind. Like the
sailing boats, Amateur Radio prevailed despite the numerous
technological advances.Even the invention of computers did not derail
Amateur Radio but greatly enhanced it." (Maxwell W3LLA)
73 und schönes Wochenende!
