Congratulations Edgar and Stefan!!

 

Amazing achievement :-O

 

Not sure if everybody can really understand how weak and buried in noise was that signal

Some kind of comparation would be useful to illustrate this work when is explained to average hams

 

Like when mass media talk about astrophysics, for example. Football stadiums not applicable here ;-)

A successful transmission, on 17470.1 Hz, of a two character EbNaut message was completed on the 10 th September 2018.

The transmitter was at JN49ik, Germany and receiver at QE37pd Tasmania a path of ~ 16786 km (10491 miles).

The message was decoded by processing the signals received on the 8 th and 10 th of September 2018.

The software used was

Spectrum Lab by Wolfgang "Wolf" Buescher  ( https://www.qsl.net/dl4yhf/spectra1.html ) and

EbNaut Coherent BPSK programs, by Paul Nicholson ( http://www.abelian.org/ebnaut/ )

The receiving set-up was a 1 m whip with a FET buffer at 9 m, a Steinberg UR 242 audio interface,

a Garmin GPS unit and Asus notebook.

Thank you to Stefan Schaefer DK7FC for his help and guidance to make this possible, and Wolf and Paul for their excellent software.
