It is really interesting to follow the activities of those using the extremely challenging frequencies below 10kHz, but can I make a plea for anyone testing on VLF to give a day or two notice when an
Hi Mike, All right. After the currently running experiment i'll run some carrier or maybe DFCW-60000. I'll announce it a few days before. Make sure a 47 uHz window is running to that time, maybe two
Thanks, Stefan. I will set a receiver up today. I always lock SpecLab to a utility station, but it is a good suggestion to display an Alpha as a check that all is working. Mike, G3XDV From: DK7FC Sen
Will be interesting to have a signal in the 36km band, Stefan I'm also running my grabber at 8270.007 with SpectrumLab and 1pps sync The 11904 Alpha is also monitored. Unfortunately still much noise
Hi Luis, Mike, VLF, A carrier is now running since 21 UTC on 8270.005 Hz. I decided to use the large coil, so i can run more antenna current. The antenna current is now 600 mA, a 6 dB stronger signal
Coming through well here, as usual a strong and steady signal http://abelian.org/vlf/fbins.shtml#p=1505559600&b=110&s=sp No E-field reception here for a few weeks. It's running but un-calibrated. Her
Thank you Stefan I'm QRV. But it's quite noise here during the weekend :( Let's see if there is any trace in the spectrogram I'll be watching every two hours :-))) PS: AMAZING signal plots by Paul, a
Today from 11:28 to 13:56 UT, I've sent a carrier from here on 4470.0025 Hz (170 mA). Then I reconfigured the coil assembly, and since 15:01 UT I'm joining Stefan on 8270.0025 (370 mA). Best 73, Mark

The carrier from Nuernberg went off at 22:30. Sat 2017-09-16: 11:28 - 13:56 4470.0025 Hz 15:01 - 18:15 8270.0025 Hz 18:48 - 22:30 8270.0025 Hz Stefan is still active on 8270.005 Hz. 73, Markus --Ursp
waterfall from a longer period. unfortunately no can't see Markus' signal, but i will try shorter periods and different noiseblanker settings VY 73 Jacek / SQ5BPF Hi Luis, Mike, VLF, A carrier is now
Also back on 8270.0025 since 7:12 UT. Good luck, Markus --Ursprüngliche Mitteilung-- Von: Markus Vester <[email protected]> An: rsgb_lf_group <[email protected]> Verschickt: So, 17. Sep
VLF, The carrier is still running but will stop at 20 UTC this evening. Mike, how does your result look now? Paul, thanks for the nice peak plot! 73, Stefan Am 11.09.2017 15:07, schrieb Michael Denni
I've set up a 8270Hz grabber at: https://klubnl.pl/wpr/en/index.php/klubnl-pl-grabbers/grabber-4-8270hz/ 92.6uHz bins, 1 hour steps. Stefan's signal is visible there. I hope to have this functional o
Congratulations Jacek Nill here over the weekend. Too much noise :( Will make a new VLF Rx setup and try in a different place looking for cleaner site 73 de Luis EA5DOM --Mensaje original-- De: owner
