Hi Paul, Tried that some 9 years ago. Did not work due to heavy detuning effects if wind speed varied slightly. What worked sufficiently was a pyramid guying at ~1/3 of the full length of the kite ro
Hi Stefan, You asked: Ordinary Deltas of ~4 m^2. Strong enough to lift myself at >4 Beaufort. We tried much more than 200m of rope and I remember my back somersault touching the wire first time. We g
Hi Mal, Interesting hypothesis! I'm observing the signal from NRK/TFK, Iceland at 37.5 kHz (314deg., 2120km) round the clock since many months. The propagation path, compared to the trace of that clo
Wolf & Markus, Thanks for explanation! Stefan, you are observing well known sunrise/-set effects and your monitor works fine now. Apart from the Russian/European "usual suspects" NAA (N. America, 24.
Stefan, No, unlikely, since it appears where a mirrored signal of DHO38 should appear at a sample rate of 44 kHz. I don't think that's accidentally. May be there's a re-sampling process elsewhere in
Hi Roelof, Sorry, as I wrote: it's a fine piece of hardware but the drivers could be improved. I'm using non Win-systems only and gave that piece away since it does not work on Linux/UNIX, even with
Stefan, 0..22 kHz. I would expect DHO38 at 23.4 kHz not at 20.6 kHz. That's the mirror from 2nd Nyquist domain. Your sample rate is 44 kHz? Peter, df3lp
Hi Stefan, Yes, impressive. I saw pictures in India some months ago. Watch that signal right on 24kHz. That's NAA from North America. Myself I'm using M-Audio Audiophile 192 only, running at 192ks ro
Hi, here's a screenshot taken at 9th of May: http://www.df3lp.de/misc/2010-05-09_0506_KielCity_comments.png Location: North Germany, 54N 10E Antenna: 15cm ferrite loop, nulls at 50/230deg., bad for R
Stefan, No, DHO38 is too strong. It's not where you expect it. Watch that trace at 20.6 kHz, broken from 0700-0755 utc. That's breakfast at Burlage observable every day. Peter, df3lp
Hi Stefan, Looking good, congrats! I wonder about that signal visible at 2100 Hz. It shows a typical MSK-bandwidth and a diurnal run not unlike the others above. May be it's mirrored from next Nyquis
Hi, ... and further up. Visible also at North Germany on all my VLF/LF-monitors. That's one of those rare "staircases" which have been observed up to 30 kHz in the past. Cannot do some RDF from where
Hi Markus, In 2009-05-18 102/282 deg. at 53N04 / 08E50 This fits for Krasnodar: http://maps.google.de/maps?ll=45.405,38.158056&spn=0.01,0.01&t=k&q=45.403,38.158 My own estimation from 2010-04-16 was
