LF,

I will transmit a 4 character message with EbNaut on 137= .540=20 kHz, sym=3D8s, code=3D4K19A, CRC=3D16.
Transmissions will start on 2019-01-16 22.00 UTC with a duration o= f 30'=20 56''; then repeated every hour. Last transmission on 2019-01-17= 06:00.

Interesting to see the phase plots. It is= =20 expected that the phase is less stable when the band opens. In the = last=20 transmission, the Eb/N0 is not high enough to see the phase=20 pattern.
I wonder if the traces become more evident if 4K19 is= =20 used.

What happens when a solar event happens during the=20 transmission time? Does it change the phase or just the D layer=20 attenuation?
Maybe we can repeat the experiment, using 4K19A. Of= =20 course a carrier could be used too, but i like to 'play' wi= th=20 EbNaut.
