Your first trials led to a new distance record for the mode on LF, well done! With the 11.9 dB at DF6NM you could have sent a 50  character message!!
As Paul says, the constant phase in the 30 minute long message is encouraging.

Repeating every hour, we could see if this still decodes with constant reference phase.
I will start an EbNaut instance on your frequency and try to get a decode this night too...

Markus and LF EbNaut,

Wow!  Thanks for your reports and I’m very happy to see early success of EbNaut trials across the Atlantic on 2200m.

Gary, K3SIW, reported successful decodes at 21.94 dB, 9.8 dB and 12.61 dB. 

Jay, W1VD, reported a successful decodes with the best at 28.28 dB.

Paul, N1BUG, reported my carrier was “very strong” at his QTH.

I’m running the same message tonight at 1W EIRP.

Thanks to all for the reports & 73,
Rob - K3RWR

Hi Rob,

got several valid decodes here in Nuremberg, best from the 5 UT transmission (screenshots attached). The signal was so strong that the spread PSK became visible in a spectrogram as a faint noise band.

Here's a list of all successful decodes between 22:00 and 6:30:

start  Eb/N0
 UT     dB
0100   3.3
0230   5.5
0300   1.7
0330   1.1
0430   9.9
0500  11.9
0530   4.6

Thanks Rob for the good work!

Betreff: LF: K3RWR LF EbNaut

LF,

I am running trial LF EbNaut transmissions this weekend as follows:

Start Time: Currently Running
Stop Time: 25 Mar 1300 UTC
Freq: 137.395 KHz
Code Rate: 1/8K=19
CRC: 24
Symbol Period: 3 sec
Message Text: K3RWR
Characters: 5, Number of Signal Bits: 576
Duration: 00:28:48:00
Transmissions Start on Hour & Half Hour
Power: 0.5W EIRP

The objectives are to test my station transmitting equipment on EbNaut and asses all signal reports and decode reports. Note: I will be able to move to a lower frequency in the band once the weather improves and I can implement changes to the antenna tuning unit.

Reports and comments welcome!

Tnx & 73,
Rob - K3RWR FM18qi
