...for some reason the PSK stopped after about 5 hours, see attachment.
This time the symbol length was quite long and the number of symbols
was small, so there must be another reason why this can happen from
time to time. I could do some tests but there is a lot of work
everywhere.  
 
Maybe someone can get a decode anyway? ;-) At least it's a challenge!
