Hi, Mephistopheles: Ich bin der Geist, der stets verneint! Und das mit Recht; denn alles, was entsteht, Ist wert, dass es zugrunde geht; Drum besser wärs, dass nichts entstünde. Peter
Hi, Some examples of comparable "staircases" received at North Germany: http://df3lp.de/cgi-bin/192/show_wf.cgi?date=09-05-15 http://df3lp.de/cgi-bin/192/show_wf.cgi?date=09-05-18 http://df3lp.de/cgi
Hi Mike, It can be received fairly strong all over the world. See: http://webflash.ess.washington.edu/spectra.html (if ON) Compared to the old OMEGA-system (50-1000kw) 500kw should be a realistic gue
Dear Mal, That guy should be able to fly since RSDN-20 is a chain spread over the whole area formerly called CCCP. See: http://en.wikipedia.org/wiki/Alpha_(radio_navigation) Why not locking to MSK si
Hi Markus, Yes, there are no or weak signals "visible" at Pacific region or southern hemisphere. Even Ascension known to be very quiet at VLF: NIL. Gruss aus Kiel, Peter, df3lp
Hi Andrey, Great! Did you listen to Krasnodar/RJH63 at 23 or 25kHz? As far as I remember both frequencies are allocated to. The first staircase at 2010-06-28 stopped at 23 kHz and had a gap when 25 k

Hi Stefan, Question: do you have a realistic guess of the frequency window of your transmission around 6.5kHz, e.g. +-100Hz? Distance is 516km, heading 10deg. to Kiel. Just modified the software runn
Hi, Coming mainly from EW here. Looking to those spectrograms since hours I'm feeling like a cleaner at the museum of modern arts: "is this art or is it rubbish?" Greetings from Kiel Peter
Hi, Well done, Stefan! I don't think that I received any significant signal. Will dive into the raw data next days. Unfortunately you did not transmit around 09:00 utc during a solar flare (C-Class).
Hi Stefan, Signal from 2nd Nyquist domain folded back. 24 + (24 - 10.6) = 37.4 kHz ==> NRK / Iceland at 37.5 kHz is very strong here in Europe. 73 from Kiel, Peter
Hi Jacek, @Piotr: tnx fer code! Yes, I'm very interested, especially in the makefile since I'm having trouble invoking the GCC against those code. More than 30 years ago dealing with Fortran - on a b
Hi Stefan, The only guess was the sample rate used, 48 kHz. (@Daniele: 48/2 = 24 kHz) Many months ago I made some tests with a cheap USB-sound-system running at 48 kHz of sample rate. It has almost n
