Hi Domenico, Stefan and all,
Thank you for searching for decodes - receiving and decoding EbNaut is the hard part while transmitting is the easy part!
Weather permitting I will transmit EbNaut again this coming weekend then will be away from the QTH for the next two weeks with no transmissions.

Hello Rob, Stefan, all
also here no decode.
Knowing the transmitted message, I have used the -f16 -M 'K3RWR_FM18QI_73' command in ebnaut linux program to check the distance from the decode.
This morning (24-09) at 04.00 UTC i found a Carrier Eb/N0 = -8.5 dB (maximun value). So decode is really very far. I found another max on 23-09 04.00 UT (-12.5 dB) respect to the other transmissions of the same day. 04.00 UT seems to be the right time for our T/A.
Just for fun, i have tried to stack these two recordings using the procedure suggested by Paul Nicholson. By stucking these two items, i found
Carrier Eb/N0 = -6.5 dB. Still far.
I don't known if the process carried out by me was ok and if the stacking method is usable at LF. Maybe should be better to stack close transmissions instead of 24-hours distant.
I will wait for further transmissions to investigate on that.

No decode. I tried all transmissions.
