LF,

I will transmit a 4 <= /b>character message with EbNaut on 137.540 kHz, sym=3D8s, co= de=3D4K19A, CRC=3D16.
Transmissions will start on 2= 019-01-16 22.00 UTC with a duration of 30' 56''; then repeated = every hour. Last transmission on 2019-01-17 06:00.

TX setup in use: Paul N. Program 'EbSynth' steered with 10 kHz fro= m GPS, analog SSB exciter with reference oscillator steered by the same GPS= , 'gpds' and 'chrony' programs for controlling the UTC time= of the computer.
Antenna current =3D 1.5 A, antenna type rev-L 8= +8 meters.

Reports are welcome.

Hello Rob and Jay,

Many thanks for the reports and all the details. Jay, did you miss the 22 UTC transmission or did it not decode?
Interesting to see the phase plots. It is expected that the phase is less stable when the band opens. In the last transmission, the Eb/N0 is not high enough to see the phase pattern.
I wonder if the traces become more evident if 4K19 is used.

What happens when a solar event happens during the transmission time? Does it change the phase or just the D layer attenuation?
Maybe we can repeat the experiment, using 4K19A. Of course a carrier could be used too, but i like to 'play' with EbNaut.

So, tonite:

f =3D 137.545 kHz
Start time: 16.JAN.2019=C2=A0 22:00:00.3 UTC
Symbol period: 8 s
Characters: 4

Hi LF,

Just a short EbNaut message tonite. I'm interested to see the phase changes on a long path. Markus's showrawsyms does a good job there, as long as 8K19A is used. A shorter message should also help to build up a clear trace.
So let's try an unusual short message:

f =3D 137.545 kHz

Symbol period: 4 s

Reports, including phase plots, welcome :-)
