Spiros,
 
you'r signal is strong and consistent = here in 4X,=20 but interestingly I'm getting multiple detections from different slices = of the=20 same transmission. The timestamp shift seems to indicate that the match = for the=20 later parts is 20 or 30 seconds delayed compared to the early part. This = would=20 mean that either my receiver is too fast, or that your transmitter is = too slow=20 by about 1%. In the latter case, I would also expect that the = conventional=20 decoder would have difficulties to get a decode.
 
Perhaps you might want to check the = samplerate of=20 the soundcard used for transmitting. You could also try to measure the = duration=20 of the Opera sequence - it should be 8.192 seconds per (half-)symbol, or = 32min=20 46sec for the whole sequence.
