Hi Jacek. Tnx for your link! Using "GNU Fortran (SUSE Linux) 4.5.0 20100604 [gcc-4_5-branch revision 160292]" it does not compile. I'm getting: ... gfortran -O2 head.f propvlf.f -o wavevlf propvlf.f:
Hi Stefan, Sounds really impressive! For comparison, this is a record from late 1998: http://www.df3lp.de/misc/SAQ_1998.wav . "T-Antenna" ==> homebrewed convertor (BF981) ==> R4c or R4b (do not remem
Hi Horst, Confirming some weak traces at 17.2 kHz, 2010-11-05, 09:00-10:00 and 13:25-15:00 utc. Unfortunately SAQ is near the "Nulls" of the antennas used here. Gruesse aus Kiel, Peter
Hi Lubos, Confirming huge effects at various frequencies between 15 up to 165 kHz. Strongest at 62.6 kHz (>20 dB, France, bearing SW). See: http://www.df3lp.de/cgi-bin/ki/plot_channel.cgi?date=10-11-
Hi Victor, Great! But what is meant by "this night" ? What is your location and time of reception - if possible in UTC ? And furthermore, where can I get some information about those transmitters you
Hi there, Anyone out there observing a strong signal at 15.1 kHz? Shows a diurnal course and raw rdf approx. 40/220 deg. from North Germany. Peter PS: @Stefan: well done! Great pictures, nice number
Hi, Checking some of your monitors called "Grabbers" (even at Israel) it's very strong (°.°) What, the hell, is that signal? See: http://www.df3lp.de/rdf/line_15100.png Peter
Hi Dave, In case of RTTY it was part of the RDL-Chain, 18.1 kHz from various locations. See: http://www.vlf.it/trond2/15-20khz.html Some sites: http://maps.google.de/maps?ll=44.77259,39.547051&z=14 h
Hi Markus, Not bad! Watch 19.2 kHz. Clear visible sunrise effect around 0100 utc. Should be one of the VTX-frequencies: http://maps.google.de/maps?ll=8.3845691,77.754468&z=14 Would be interesting wha
Dear Jurgen, Because some people, a minority, want to hear it, listening to that quality of information - wherever you are. Think green, turn your car engine off. "So schreitet in dem engen Bretterha
Dear Colleagues, That whole discussion is a nice proof for the importance of a principle what is called "Freedom of Opinion". And furthermore how necessary dissenting opinions are for generating crea
Hi Jurgen, Receiver kaputt? Please compare 16-26 by 36-46 kHz in that plot. Additionally there are some signals visible above 50 kHz never been observed by others. Gruss aus Kiel, Peter
Hi again Jurgen, It's a "ghost" of MSF, 60 kHz, which is incredible strong over there. All other signals appear twice in your plot shifted by +20 kHz. I don't know what happend since I do not know (i
Hi Jurgen, That's right. I'm monitoring VLF/LF since many years, 24/7. That signal at 26 kHz is a new one, transmitting sporadically since some days. My guess is Greek or Turkey. Most VLF/LF frequenc
Hi Markus, Thanks fer info, unfortunately bearing is ~45 deg. from here - and that's too close to the NE-minimum of the 20cm ferrite loop laying on the floor at basement. Next project should be an E-
