Thanks very much to Michel and Domenico, and also to Riccardo who managed to receive the afternoon experiment. I'm glad to read that people are setting up EbNaut receivers, and hope that the signal may be useful. It's not unlikely that noise conditions will improve later tonight. 

All the best again,
Markus

Hello  EbNauters,

different story here in JN80. Signal from Markus was strong at 20.00 but was impossible to decode at 21:00
most probably due to high QRN from thunderstorms near my area.

Message: DF6NM

UT    Eb/N0 syn  Eb/N0 carr
20:00         8.7         10.4
20:30         5.4         7
21:00          NIL

Nice to see more people playing with EbNaut.
73, Domenico iz7slz

Hi Markus,

Excellent signal so decoding was a breeze. Hopefully the antenna was tuned on 630m

 I intend to run a few more EbNaut tests tonight. This time I will use a 137490 Hz carrier from my Rubidium-controlled decadic synthesizer and a diode PSK modulator. 

137490.000 Hz
5 characters, 8K19 
1 second symbols
Starttimes 20:00, 20:30, 21:00 UT (with no extra delay)
Duration 512 seconds

Best 73,
Markus
