Hi VLF,


Thanks Stefan and Markus for your detailed reports.

Ok Stefan, I'm agree, we can try: a new message started at 1600 UTC, same scheduling for the following transmissions.

QRG: 8270.003 Hz
6 ch.
25 sec./sym
coding 16K21A
CRC 15
duration 7h 53' 20"
antenna current about 600mA

GL and thanks again for your patience :-)


P.S.: now there are some thunderstorms nearby, I hope I won't have to stop the TX :-/


All the best

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:
