Marcus and Rob,

I believe this is a first historical TA 1way QSO in EbNaut at 136 kHz and at a very good QRB=6744,1 km. Congrats! 

With pleasure I bring it in "Best QSOs" list  http://136.73.ru/h_qso/index.htm

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
