GM Lubos, VLF, You are strong visible at OE3GHB and Paul Nicholson. The QRN is pretty low this morning, just like yesterday. There seems to be a trace slightly above 8970.04 Hz on my grabber but i st
GE, Stefan! I am pleased, that my signal was seen in UK, that is great! The weather was fine and my PA worked without problems. Thanks for your coments about SL. I must think about that. My signal wa

Hello Lubos, Still, there is a clear trace just above 8970.04 Hz but the letter "K" is not really readable since the SNR is poor and the element length (3000) is a bit short then. 3 dB QRO would make
Hello Lubos I will be looking for you today. I have a line yesterday on 8970.048 seen from1200 UTC does anyone own this? 73 Eddie G3ZJO On 04/05/2011 04:42, Lubos OK2BVG wrote: Hello VLF! The weat
Hi Stefan, That looks simple enough and from what I see, there are other happy customers (4x1RF, G3XBM and TF3HZ) so I'll make one. :-) Don't have the BF862 FETs but may have something similar, maybe
Hello Stefan, VLF! Yes, I saw my signal on Gerhard´s grabber, but not on the yours, I am sorry. May be sometimes later :-) Although this, the main goal of todays experiment was fulfil. My new rubidiu
Hello Lubos, Excellent! We're looking forward to your signal :-) Just in time my VLF grabber (http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html) is available again, after a PSU fai

Hello Lubos, VLF, You are 20 dB S/N at OE3GHB, http://members.aon.at/grabber/VLF/index.html and some hints of a trace at Paul Nicholson, http://abelian.org/vlf/fbins.shtml#p=1319108400&b=140&s=sp but
Hi Lubos, Great about the kite antenna!!! Yes, i'm waiting for wind too, since some weeks. It comes from east which is unfavourable on that /p QTH. Maybe if we have some luck, we can make the first D
Hello VLF friends! I did my first test with kite as an antenna for 8970Hz today: **INFO** Date: 25.10.2011 Time: 14:00 UT - 16:00 UT Antenna: Kite GP 150m long (120m effective height) PA: 120W Identi
Hello VLF enthusiasts, I am interested in joining the VLF party. I have already tested a nice audio amplifier which will produce 100W RMS on each channel and is easy to bridge. I haven't given a lot

Hi Lubos Very nice signal in 47uHz here 10dB above the noise, a pity you will not be on longer so as to give more more than a nice white dot. :-) Very nice to see you excellent signal again here. 73
Hi Gerhard, I'm just testing a loop antenna on VLF, pointing to you. It is a hula hoop circle with 80 turns inside. Just some first tests. The loop is directly connected to the soundcard, all far fro
Hello Gerhard, A recording would have been halpful now. Maybe it was due to the settings? How did you switched to DFCW-120? Manually or by using the predefined settings? There may be a difference in
