Hi Paul,

That sounds very well. What was the message? :-)
The error map of this decode would be interesting (maybe with and without the diurnal phase correction).

Easy decode, +3.3dB with constant reference phase.

Decoder continues to run, I expect a better decode with
some phase pattern that compensates for the day/night
