Hi Stefan
Your second transmission at 00:30 UTC was still stronger
Signal decreasing after that and last transmission at 06:30 was just 4.5dB Eb/N0
It is very nice to see the 8 transmission in the slow spectrogram
Thanks Luis.
A nice SNR! You will manage the 50 characters as well i bet. Even 200 chars would be no problem.
But for me, using SpecLab to key EbNaut, it is not possible to use shorter symbol length than 1 second. Also i remember i have a PTT watchdog which interrupts the transmission after a duration of something between 30 and 60 minutes. So maybe it will clip a
few minutes at the end of the coming message, we will see ;-)
