Рикардо IW4DXW и Доменико IZ7SLZ провели интересный эксперимент на ДВ 137.480 КГц.
Впервые с помощью Ebnaut передали 400 символов сообщение - кусочек стихотворения итальянца
Giosuè Carducci.
Hello LF,
Riccardo has used nice poetry for the 400 characters message sent yesterday. There were present some apostrophes in the text that were counted by ebnaut-tx.exe but not sent. So the exact number of characters sent on the 17.10 UTC message is 392.
After increasing a bit the ram memory of the pc in the shack, i was able to decode his message:

The poetry written by Giosuè Carducci, talks about scenes of the coming winter in a village.
Huge signal from Riccardo decoded here with Eb/N0=7.9, as we can see also in the 'Markusplot' attached. He used about 200 W and our QRB is 650 km.
