Re: LF: EbNaut from Todmorden

Hello LF,

Some good results of EbNaut signals from TodMorden here in JN80NU

Got some decodes of the Paul message:

Time  Eb/N0_sy  Eb/N0_c  rank

00:00 0.7  -1.6  1260
01:00 3.3  3.6  0
02:00 -1.7 0.1 16334

Wave files are available at this dropbox link

In the attached waterfall are also visible the signals from R7NT and G3XDV wich i have detected with opds

https://www.dropbox.com/s/3l8la03yrpqdo0j/DETECTED.TXT?dl=0

Their signals are quite stable in a short period, so i think that Alex and Mike can attempt an EbNaut transmission of 15 minutes.

Have a good Sunday !

Here "orecchiette with tomatos",  tipical dish of Apulia,  are ready !

Attached is a 0.438 mHz spectrogram of your carrier and a phase plot of the "best" decode at 3 UT. As opposed to MF, the phase on LF was generally rather stable, and displayed symbol Eb/N0 appeared higher than that for carrier.

All the best,
Markus
