Hi all, Tomorrow the rain probability is just 10% and so i think i can risk to run a short VLF experiment on 8970.00500 Hz. I'm using the fixed antenna at JN49IK00WD. These days, the QRN is very low
Hello Stefan, VLF! Your signal is clearly seen in QRSS 6000 and on top of that in QRSS 600 :-) GREAT ... I am pleasuere to see it after long time. Lubos, OK2BVG, JN88KS ** Date: Sun, 15 Dec 2013 05:1
Peter, Is the Flux Density scale on your grabber calibrated? In femtotesla? Stefan's signal strength seems to be in the 0.1 to 0.4 range on your flux density scale. If Stefan's signal strength is nea
Hello Stefan! Thanks for your positive assessment of my new VLF set on the Apollo grabber. As you know, I changed my VLF receiver during the holidays. This one is the "second generation" of my grabbe
Stefan, I did not capture raw A/D data during your 8970.005 transmission yesterday, but I have figured out how to do so and will be ready next time. Based on SNR yesterday at Todmorden and virtually
Stefan, this is great news! I've reconnected my VLF preamp in series to the 74 kHz tap on the antenna, and reactivated the VLF grabber: http://df6nm.darc.de/vlf/vlfgrabber.htm I'm also trying to expo

Hi Jim, My ERP was in the range of 500 uW. I suggest to monitor the signal on 11904.7619 Hz, just to check that your system is stable over a longer time. This test is very useful. But you'll need the
Stefan, Signal is O.K., but stabillity is'nt :-( To much spread around center frequency. (I know.... I'm complaining about 0.01 Hz drift..........) 73's Peter Since 4:10 UTC, the signal is available
Hi Peter, VLF, Did you see a trace on your grabber? Can you show me a link or a screenshot? The signal is well visible on Paul Nicholson's excellent VLF grabber, http://abelian.org/vlf/fbins.shtml#p=
