No decode of this one.

Let's try.

Frequency ok, carrier and successful decodes showed no
phase shift over long periods.  Signal too weak to check
for short period phase changes.

I haven't looked to bit clock offsets, I assume with these
long symbols that it won't be a problem.

Eg 13:30 to 14:30 but the noise was low.  And there are
short periods when it is completely red.  Even random
noise would only give half red.  Probably just statistics.

No so much, 60 degrees, and I can compensate for that before
the decoder.   Day/night phase change should be less of a
problem as we go to lower frequencies.  LWPC is not much
help without a better ionosphere model than its basic
LWPM model.
