Hello Paul, VLF,

very well!
I saved the image to my VLF folder. Another achievement i am happy with.

Jacek, are you reading this? Do you like to try to decode it too?

73, Stefan

I got no useful signal during daytime on the 22nd.

But I combined the night and day signals, adjusting
for the observed 20 degree nighttime phase lag.

Now we have 14.0 dB S/N in 23.1 uHz, 5 sigma:

A detection distance record for the 67km band.
Not bad for 5uW ERP.
