My earlier decodes of VO1NA,

 time   Eb/N0    Phase
 21:00    9.6    30 30 30 30
 21:30   13.3    0 0 0 0       (offset 1.8 seconds)
 22:00   12.0    0 0 30 30
 22:30   10.8    150 150 180 180

And taking further advantage of the time offsets worked
out by Markus, I can add

 23:00    6.8    150  150  180  180
 23:30    3.7    180  180  150  150
 00:00    5.7   -150 -150  180  180
 00:30   11.1    180  180 -150 -150
 01:00   16.9      0    0   0   0
 01:30   13.3    -150 -150 -150 -150
 02:00 no decode

Best signal after midnight, which was the case the other
day with the carrier from VO1NA.   Peaks about an hour
later than the peak at DF6NM.

Looks like there's a window from 00:00 of a couple of
hours for a QRP transmission with long symbols, say 8 or
10 seconds and a stronger code, 8K21A.   Should be able
to drop the power 20dB for a reasonable challenge.
