That may decode in one attempt if lucky, but likely two
transmissions will be needed.  If it does decode, then
the chance of it being the correct decode from random
noise is 0.02 %.

Can you run until 08:08 UT with CRC 12 and the other
settings the same?  A gain of 0.74 dB which will make
a good difference.  And if it decodes, the chance of
a random correct decode is only 0.0004 %.

I hope the weather doesn't spoil the transmission, but
if you keep trying, you are sure to succeed.
