Re: LF: More EbNaut tests on 137490 Hz

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.

Nice to see more people playing with EbNaut.

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 -----Ursprüngliche Mitteilung-----  Von: Markus Vester <markusvester@aol.com> An: rsgb_lf_group <rsgb_lf_group@blacksheep.org> Verschickt: So, 9 Okt 2016 2:41 am Betreff: LF: EbNaut tests 137508 Hz 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.
