Thanks for the nice message decodes. It looks lkke it was a good night :-)
actually i've tried to decode 3 hour segments from 18:00, 19:00 and 20:00.
the 3-hour transmission from 18:00 decodes fine, the 19:00 and 20:00
3-hour segments don't decode. it seems that the beginning of the
transmission was best. maybe next time please start earlier?
btw for those who don't remember vlf radioamateur history: we went from
joy because we were able to decode a simple carrier from a high power
transmission using a kite antenna, to decoding multi-character
medium-power transmissions with ease. this is a big achievement of Paul
(who wrote the software), and Stefan, Markus, Uwe and others (who just
transmitted, instead of believing that it won't work), and many rx
stations (who worked on their rx systems, even though there were
absolutely no man made signals in this band previously, and it was common
knowledge that it won't work anyway).
i remember the early vlf work being done here and elsewhere (we've
probably all done some unofficial vlf experiments which were not published
for various reasons), and compared to a few years ago right now it's
almost too easy to receive a transmission :)
