> A three character message "UFB", transmitted by Stefan Schaefer
> (DK7FC) at JN48ik, has been received at QE37pd a distance of 16778
> km.
>
> The message was encoded and decoded using the EbNaut software by
> Paul Nicholson. http://www.abelian.org/
>
> Spectrum Lab software by Wolfgang "Wolf" Buescher (DL4YHF) was
> used to capture the data. https://www.qsl.net/dl4yhf/spectra1.html
>
> Software provided by Markus
> Vester (DF6NM) was used to normalise and stack the data to be
> decoded. http://www.df6nm.de/
>
> The result was obtained by stacking the data files received
> during the 21 st and 26 th of September.
>
> The receiving set-up used a 1m x 28 mm diameter aluminium whip at
> 9m with a FET buffer.
>
> A Steinberg UR242 Audio Interface and ASUS note book were used to
> capture the data files.
>
> Thank you to Stefan, who made this result possible.
