Yes Marco,

you get the proper results, notwithstanding some bugs on my launcher..

- It not manage the change of the date so it is necessary to put the time as 24:00:00.000

- when reading the sr.ini file, it not manage the "," as separator for decimals but "."  so it is necessary to set this function  temporarily in Windows' control panel and reload the original sr.ini file from Markus

Did you see the Loran lines (i.e. on 137525.000 kHz)  giving *** as decode results ?

Thanks Domenico and Markus for the "demo file".
Think i passed successful the decode training of the 3 transmissions. Only R7NT is only a single chat? (Sym 5.0 Len 1 crc 16)

Dear Markus 

Thank you very much for your kindly Report.

Maybe you can share with community the file with your exported fft and tell us your Spectrum Lab fft  parameters. 

This should be useful for training on ebnaut.

Thanks in advance.

Okay on TX end problems. On RX end ... second spectrogram shows signal from K2ORS beacon depressing noise floor some dB. I will ask Warren if he can shut down for a night for our next attempt. Let me know when you will be back to transmitting ... always happy to look for your signal!

Hi LF

Thanks Jay.

Sorry but this night my TX suffered of many protection event, I think for antenna mismatch due to humidity. There is no transmission from 0200 to 0500 UTC.

It's so hard, Jay :-/

I will try again soon, maybe this evening.

Many thanks

All the best

Sorry to report no reception again last night ... even with the new 3 character message. As Markus points out this may be a difficult path. Not sure I've ever received a station from Italy over all these years on LF.
