Here is a corrected and continued list of the results of your transmissions:

Date Carrier Eb/N0 [dB]
09.May_08:00 -1.3
09.May_16:01 -6.1
10.May_00:00 -4.9
10.May_08:00 -6.8
10.May_16:00 +0.9 decoded
11.May_00:00 +6.9 decoded
11.May_08:00 -2.7
11.May_16:00 +4.8 decoded
12.May_00:00 +7.0 decoded

PS: You could try to transmit your full callsign for example. It would work here. A higher challenge.

Hi Riccardo,

Now i finally got your message, see attachment. The transmission of tonite 0 UTC was very strong, as i would usually expect.
It must have been the QRN. And now since know the message i can look for the S/N or Eb/N0 of each of your transmissions:

Date Eb/N0 [dB]
09.May_08:00 -1.3
09.May_16:01 -6.1
10.May_00:00 -4.9
10.May_08:00 -6.8
10.May_16:00 +0.9 decoded
11.May_00:00 +7.9 decoded

QRG: 8270.003
2 chars
30 sec/sym.
coding 16K21A
CRC 27

Thanks for reports, as usual...

All the best
