OK lets give it another go.
8K19A, 10 characters, 1 second symbols, 752 seconds

and a bit more power...

starting 2245 and each 15 mins.

GL & Thanks to all

… yes Joe, 10 chars and 75 watts might have done it (just ;-)

Suggestion: 8K19A, 10 characters, 1 second symbols, 752 seconds total. If 
possible, try to use above 100 W as some margin for QSB will probably be needed.

Listening now…

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.

Got some pieces of carrier in the spectrogram, up to about 10 dB SNR in 1 mHz. 
Considering the carrier duty cycle (8.5 out of 15 minutes), that would have 
been about +15 dB in a mHz for a pure carrier, or -15 dB EbN0 at 1.1 bit/s net 
data rate - no chance for a decode here.
