Thanks Markus - of course you Stefan and Paul should be credited with
your patiently helping me.
The PSK is now off -- just the carrier now.

Somewhat belated I guess: My congratulations to Joe and Paul on this nice piece
of work!
I dare to hope that a few photons from Canada will soon be detected in mainland
Europe.
Best 73,

CRC was 16 bits.
Copied 'VLF' with constant reference phase.
H-field: Eb/N0 = +1.4 dB, phase 155.7 deg
E-field: Eb/N0 = -0.2 dB, phase 152.5 deg (new RX)
Combined: Eb/N0 = +3.0 dB, phase 154.4 deg
First sub-9kHz message Canada to UK.
Looks like the rough cal of the new E-field rx is working
pretty well. I can't improve the combined signal any further.
Looks like there's plenty of signal to spare. Later I'll
suggest some new settings for the coding.
I don't think I'll get the 11:00 repeat, my receivers will
probably be off this afternoon.
