Re: LF: More EbNaut tests on 137490 Hz

[Markus Vester <markusvester@aol.com>]

Things seem to be stable now. I will let it run through the night with repeats starting on each full hour. All reports would be much appreciated! 

All the best,
Markus (DF6NM)

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)

Tonight I tried to generate EbNaut transmissions using SpecLab's digimode modulator. After finding a workaround to avoid unwanted differential encoding, I was able to decode my own transmission locally. A five character message will now be sent 1.5 seconds after each hour, until 6 UT.
