Hi Markus,

Uuuh, chatting with max. 5 characters will become difficult i think :-) As in JT-9, there should be 13 characters, so one can at least write "i have a cat"... :-)

Well, what does one need to arrange such a decoder? How is the message displayed? Is it possible to run a detection window, as a text file, like in OPDS?

yes, you guessed right, the message content was indeed "DF6NM" ;-) Let me cite from a recent direct mail to Paul:
>> I was using a somewhat guessable message, foreseeing a possible "official first" demonstration. Maybe a truely random message would have looked even more impressive ;-) Anyhow as this is formally not "amateur radio" but rather using an unallocated frequency range, so there's no need for an allocated callsign. Maybe if you'd set up a transmitter (relatively easy) and I'd learn how to decode (the hard part), we could start chatting away on VLF ;-)

Hello Paul, Markus,

Well done! Interesting stuff. I see you never stop to find some new
things to try :-) Well well, i should think about...

What was the contest of the message? A complete callsign, DF6NM?
