Re: VLF: VO1NA in Todmorden on 8270 Hz - also in Amberg?

[Markus Vester <markusvester@aol.com>]

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.
