Hello Markus, LF,

Transmissions from you and from Riccardo have been decoded here.

Congratulations for the good going.

I'm still trying to extract the 21.00UT message from DF2JP but NIL till now.

BTW his carrier was strong here in JN80 so it is only matter to guess the right frequency and time offsets.

Compliments also to Joe for his EbNaut tests. If necessary, i can change settings of my auto-decoder if Joe wants make further transmissions.

It is a bank holiday today here and the neighbor garage - jamming my LF reception during the day - is closed. So very low noise now: good for testing EbNaut with ground waves.

All the best

Domenico, iz7slz

Good decodes of the 21 UT transmissions from both IW4DXW and DF2JP. Joe was on 137523.8183 Hz at the time, with a phase shift of only 140°. As the frequency difference between the two stations is not an integer multiple of 1/3 Hz, the mutual interference does not cancel in the 3 s symbol period, and we can see that the stronger signal from Joe is slightly widening Riccardo's phase track.

Will start looking for your EbNaut signal, as well as Riccardo's, at 2200 Z. Sunset here is currently 2317 Z. Okay on Joe's signal being unlocked.

I have repaired my antenna and intend to come on 137520.000 Hz again tonight (8K19A, CRC 16, 3 s, 5 char, starting on the hour 22:00, 23:00... 04:00 UT).

Joe DF2JP is currently transmitting a bit below 137524 Hz, but the oscillator still seems to be unlocked and drifting too much.

Hi LF!

Many thanks to Jay, Alex and Markus.

Markus (with Jay), congrats for your TA and thanks to everyone for reports and decoding efforts.

Ok, Jay. I'm ready for another attempt, with the same QRG (137522.000313 Hz) and EbNaut coding parameters.

GE and Happy Easter to all
