Re: LF: EbNaut April 1 / 2

[Markus Vester <markusvester@aol.com>]

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
