Edgar and Stefan, an excellent and undisputable result, another step forward! Best regards, Markus ----Ursprüngliche Mitteilung----- Von: Edgar <[email protected]> An: [email protected] <[email protected]>; 600 <[email protected]> Verschickt: Di, 2. Okt 2018 4:14 Betreff: LF: EbNaut - message received 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.
