[Alex K <rn3aus@gmail.com>]

Hello VLF, Stefan
I'm glad to report about sucsessfull decode of 1-char ebnaut message sended on 5170.1 Hz 20,22,23 and 24 October.
Message was decoded by weighted stacking, unweighted stacking and from 23 okt file only. Other files give very poor decode with many false decodes or only false decodes.
In attacment we can see best decode from weighted stacking.
Also all ebnaut-files is available here: http://rn3aus.narod.ru/5170.zip
My VY congratulations to Stefan! Abt 2000 km on 5170 Hz!
