Hi Markus! I think I can see your signal here in JN88hl. Unfortunately I just have started about half a hour ago because I had to calibrate and set up the SpecLab first. I have set a 500µHz window an
Hello again! Sri Markus but meanwhile I'm not sure if it's your signal I saw. It disappeared now. I think the time is too short and the noise is too high at this time to tell something meaningful. An
Dear Group! Signal is >20db over noise in JN88hl. I'm missing QSP to the reflector. I don't want to miss when Stefan QSY to 6 and 5 kc. Has anybody information about when this will happen? 73 OE3GHB
Hello Wolf! I guess it is what you call a "Soundcard-based SDR.... YU1LM-design: DR2B Basically it works very well and the Mirror Frequency rejection is at least 60db without using SPecLabs optimizat
Hello group, dear Stefan! I will participate and change my grabber settings Thursday evening. 73 OE3GHB Gerhard Am Dienstag, den 16.11.2010, 21:11 +0100 schrieb Stefan Schäfer:
Hi Mal! As far as I understood it is regarding 137 (= LF) but meanwhile I'm not sure either.... 73 es looking forward to a QSO on LF! OE3GHB Gerhard Am Freitag, den 12.11.2010, 22:16 +0000 schrieb ma
Hello Stefan! The fence was just used in the first attempt for transmitting and is meanwhile replaced by Ossi's LF-antenna. Still Ossi is using fences around his QTH but only for receiving and to che
Hi Stefan! No, I wasn't meant that urgently...I just thought about leaving a message to the reflector before leaving home... I already have tried your config file on the "old" notebook and so far it
Stefan! Only a very weak trace here so I guess it came from the west! 73 OE3GHB Gerhard Am Freitag, den 19.11.2010, 21:54 +0100 schrieb Stefan Schäfer:
Hello group ! Among others, I'm experimenting on VLF. Today, I applied about 70W on my 16m high Marconi. The loading coil is a Variometer (460-580mH) and the capacitive load of the antenna is about 6
Hello group! Ossi asked me to give you an overview about his set-up. We spent many ours on the phone during the past weeks and I assisted him in building the system. The PA is a car-audio equipment r
Servus Stefan! Yep, you can count on me too! I will get back from work tomorrow at 15:30z and I will have to use my "other" computer for this experiment cause my usual VLF-grabber (old Toshiba notebo
Hello group! Thanks to Alan, Markus and Laurence for the answers: Markus stated it could be an "inverted field-mill" effect: As far as I can imagine, then the wire itself is vibrating, thus the sound
Hi Stefan! Also no reception here. Nevertheless, this shouldn't be a reason to give up! I (and many others I suppose) like to be a part of your experiments and we hope for the next time! I think rece
Hello Mike! As usual, you are very well visible on my grabber. members.aon.at/grabber Recently, you nearly overdrive my range settings and your signal was pure red colour, means at least 25db over no
Dear group! After weeks of testing and playing around with different kind of equipment and antennas, Ossi OE5ODL has managed to transmit a signal on VLF which is received by his grabber www.langwelle
Hi Ken! It all depends on the antenna your are going to feed with this loading coil. My system has a capacitive load of abt. 600pf and so the coil is abt. 2,3mH. This is realized on a flower pot with
Hello Stefan, Lubos! Unfortunately it was not me! I was in my office at this time and I don't think my wife switched on the VLF-transmitter. I told her to keep at least a distance of some meters to a

Hello Daniele! I can't comment on the BBB4-RX because I don't know about it's design. In my experience, a MiniWhip (PA0RDT, tnx Roelof)-like design of antenna, is the best and most convenient way to
