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
