Well done Stefan and Domenico.  That put a smile on my face - Thank-you!
The message was decoded as sent except for an exclaimation mark and
some apostrophies which evidently didn't survive the transatlantic voyage.

Prof. Gill taught the course I did at Memorial University last semester.

EbNaut again tonight:  2300 utc and every 15 mins.  150 watts 2 amps
137.477 kHz 54 characters 1432 0.2 s symbols, 4K19A.

73 to all

Hi Joe, LF,

Domenico seems to have a modern PC :-) He decoded your message as received here :-)

Good afternoon Stefan,

thanks for posting the audio file. I tried the decoding procedure with success !

The question is : Who is Prof. Gill ?

Joe VO1NA made a very strong transmissions last night but still no decode here. I will increase list lenght and hope to get his message with high rank number.
Again many compliments.

  Hi Joe,

  Thanks for the feedback.
  Yes, 137.477 is fine.
  A text file has 1516 kB here. The one that could contain your
  message is at
  Markus already asked for the file to try to decode what i received
  in JN49IK. My sr-file contains "30000.6436 128 524288 137500".

      Hi Stefan,

      Perhaps I should QSY back to 137.477 again!  On 777 tonight and will
      try 477 tomorrow if that's OK.  How big are the text files?

      I use your grabber to check my sigs.  Thanks for this service!

          Hello Joe,

          I'm sorry, i forgot to mention that i'm getting my EbNaut
          decodes from the exportet FFT data (text files) from OPDS.
          That means the transmission must be somewhere arround 137.5
          kHz +- 50 Hz.
          Maybe i can search for a PC with 64 bit here in the
          institute to decode your 155 char message. I still have the
          text file :-)

              OK Stefan, lets try a shorter message (54 chars) tonight
              starting 2300 utc and every 15 mins.  150 watts 2 amps
              RF. 137.777 kHz  1432 0.2 s

              I like my 32 bit machine too!

              Thanks for the helpful advice Markus.  I noticed the
              different colours
              on your grabber.  Will go for a shorter message this time.

                  Hi Joe,

                  Unfortunately it looks like the EbNaut decoder can't
                  decode 155 characters on this PC (4 GB RAM). The
                  number of characters seems to be limited to 66 :-(
                  I don't have any 64 bit systems available here.

                          Thanks, very nice. 131 characters in 0.2 s
                          symbols, that's great!

                          Joe, could you run a similar transmission
                          again? Maybe with a longer text :-)

                              Hi Joe,

                              Is it right that you sent some EbNaut
                              with many symbols on LF in the
                              past (last season) ?
                              I didn't give it a try that time. Now i
                              would be interested in a TA
                              detection of an EbNaut signal.
                              Which symbol length did you choose that
