Deja vu ... seems like we've been here before ...
 
The receiver / SpecLab was set up earlier in the day to receive Stefan's transmissions on 137.545. Unfortunately, both of your announced frequencies are outside the passband in the current setup ... which is approximately +/- 3 Hz. In the future it would be best if you could stay within 3 Hz. Think Marcus advocated for 1 Hz separation in the past. 
 
Will be happy to look for your EbNaut signals another night.

Hi LF & EbNauters.

Ok, Stefan and Domenico: I'll join you with the same transmission coding and parameters on 137.535 kHz (message repeated hourly, 1st on 2100z, last on 0700z).

Reports are welcome.

All the best

LF,

I will transmit a 4 character message with EbNaut on 137.540 kHz, sym=8s, code=4K19A, CRC=16.
Transmissions will start on 2019-01-16 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 from 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 = 1.5 A, antenna type rev-L 8+8 meters.

Reports are welcome.

Hello Stefan and LF,

results of decoding for your EbNaut signal in JN80nu are at https://qsl.net/iz7slz/EBNAUT/DECODED.TXT

Attached to this email there is a folder with the plots of the eight periods. First two transmissions seems to be affected by fading.

I want to join your EbNaut session tonight with some transmissions from my side. I will announce the parameters as soon the setup is ready.

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 = 137.545 kHz
Start time: 16.JAN.2019  22:00:00.3 UTC
Symbol period: 8 s

CRC bits: 16

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 = 137.545 kHz
Start time: 14.JAN.2019  22:00:00.3 UTC
Symbol period: 4 s
Characters: 4
CRC bits: 16

Reports, including phase plots, welcome :-)
