Good timing with that.  Now Stefan is going to repeat
a 3 character message each night, with exactly repeating
timing and phase.  This allows the signals to be added,
to accumulate enough S/N for a decode of the message.
Stacking - a bit like the technique astronomers use for
images, except that this is coherent.

We have to hope that the propagation at 17470 Hz allows
the rxed phase to repeat well enough.  Don't worry about
the odd timing break, vtcat -p takes care of those quite
nicely.

Good luck, and if you see a high load average on your
vlf02 PC, you know it's doing some useful work!
