Stephan and LF EbNaut,

The first overnight results are encouraging that EbNaut= may well be a viable QSO and communications mode for 2200m!  

I would be pleased to begin testing of other end of the env= elope with a 50 character message repeated hourly. I will start that later t= oday and post a message when implemented.

Hi Rob,

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.
Maybe you like to try something just to see what's possible: http://abelian.org/ebnaut/c= alc.php?sndb=3D17.68&snbws=3D0.000033&snmps=3D&code=3D8K19&s= p=3D2&crc=3D18&nc=3D30&submit=3DCalculate
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...

73, Stefan

Markus and LF EbNaut,

Wow!  Thanks for your reports and I=E2=80=99m very happy to see e= arly 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 =E2=80=9Cvery strong=E2=80=9D at= his QTH.

I=E2=80=99m running the same message tonight at 1W EIRP.

Thanks to all for the reports & 73,

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=3D19
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
