Thanks Markus and Roelof for the reports.

I'm guessing a slower bit rate and more power might help.
Please feel free to make a suggestion and we'll try again
tonight.

     Hi Joe,
    
   even though the noise is less than ideal here, I'll will be watching and saving data for possible decodes. There's an updating spectrogram https://dl.dropboxusercontent.com/u/26404526/opds8.png on the opds page - if you leave the carrier on between EbNaut rounds, it might become visible and assist in checking the decoder frequency offset.
    
   Good luck,

 Hi Domenico,

 All set up for 2200 utc tonight and at 15 min intervals thereafter.
 75 chars K19A 1936 symbols 387.2 seconds 10 watts continuous carrier
 unless the FET fries!

 The same DOCXO ref osc will be used, but there may be a (small) rounding
 error in the frequency.

 Good Luck 73

 > Hello Joe, group

 I don't known if you are using same stable exciter that you have used in your
 recent LF EbNaut test. 
 If so, i invite you to try  some  EbNaut transmissions on MF in the next days. 
 In good condx i often copy some traces of your MF signal here in JN80, so it
 will be an interesting experiment try to decode some 
 T/A messages from you.


 Thanks in advance.

 73, Domenico IZ7SLZ
