Sorry, I could not decode any message.  There is some unknown
timing delay from the PLL so I searched from 10:59:59.5 to
11:00:05 but could not decode anything.  I tried combining E
and H receivers but that didn't help.

The carrier sent before the message had S/N about 3dB weaker
than your signal in November.  That would have been enough to
make a decode with 10 second symbols unlikely.

Unfortunately Wolf's on-line receiver was down for maintenance
so I couldn't borrow a signal from there to try.
