Michel,
looking at your screenshot, I would agree that
the weak trace on 6469.97 Hz was almost certainly caused by Stefan's
transmission. Very nice!

Hello Michel,
Thank you very much for the
interest and the appempt to catch the
signal. It's the first time i read
something from you (regarding the VLF
tests) and i am generally impressed by
the amount of people in so many
different countries who are present here on
this reflector. The
reflector gives the feeling as something private and/or
collective, not
so in an official web platform (personal
interpretation).
Thanks for describing your RX setup,
interesting!
Well, about your picture: If the time is in UTC, it matches
the time of
my transmission very well! Sadly i have not transmitted a real
character, such as "K" or "C" or so. But your trace is stable in
frequency! This is not the case for the most signals on VLF!
Additionally, the trace shows the typical frequency offset of my DDS
VFO, about 30...40 mHz lower than in the display! This are all
indications for my signal! So i would say yes, it is a positive
reception.
Maybe some others can comment if it can be seen as a valid
reception. I
would say yes.
You can imagine how the reception would have
been some hours earlier,
when the QRN was 10 dB less! :-)
Michel,
what is our distance? My locator is JN49IS.
Best 73 and i hope you will
be there in the next test as well :-)
