Gerhard, VLF, Are you transmitting at 8969.98 Hz? There is a strong signal on your grabber and on mine as well! http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html The signal is O co
Hi Chris, Congrats to the clear reception at M0BMU! Who is the next distant well equipped RX station? I have extended my "DFCW-6000"-window at http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_
Hello Horst, I may give you a wideband.usr file which allows you to check the whole band your soundcard monitors. If you run it for about 12 hours, you/we will see the SNR of the MSKs and Alphas but
VLF, Today i received a well visible trace of OE5ODL. Ossi has improved his system and increased the antenna current from 180 to 300 mA. It is the fixed antenna, no balloon. If the frequency could be
What's the meaning of "CWNR"? 73, Stefan Am 26.01.2011 14:19, schrieb Szigy: From: YO2IS Hi Mal, it was DJ6GT he was M copy here in KN05ps You had audible signal on top of a QSO, CWNR ! 73 Szigy.
Congratulations Ossi and Gerhard! Nice words and work! :-) I am looking forward to your next transmissions! Since a few hours my VLF grabber(s) are running with the new SL settings i found by re-proc
John, Why don't you just disconnect the battery when the car is standing still in the field? :-) Well, i was thinking about investments into this old car and if it is still worth or not. But having n

Hello Szigy, OK, tnx for the info. I've already thought it means "CW never reaches" or so ;-) Well, if you can see DJ6GT, your RX must be excellent. DJ6GT is relatively local to me but rather weak he
Hi Nicolas, Yes, just see the grabbers! But the signal seems weak today. Probably there is wind and no chance for the balloon antenna... I can see him in my 6000 window but just about 10 dB weaker th
Dear group, especially Andy/G4JNT, Maybe a little out of topic but very useful for LF/VLF devices: Programming microcontrollers. Before some years i worked with some PIC controllers, assembler. But i
Dear group, Since a long time i wanted to publish the circuit of my "big" VLF PA. It is titled as a 600W PA since it has never handled more power so far, due to the power limit of my /p generator. In
Hi Gary, Well, i see an offset of the Alpha trace by about 20 mHz, so your SL session is not locked to a reference signal. Furthermore the Alpha trace is suddenly disappearing. Why? There was no temp

Dear LF/VLF group and further VLF watchers :-) After another very successful, exciting and fascinating /p VLF experiment i want, as usual, thank all the many (>=24) receiving stations who took the ti
LF, Ossi moved to 6470 Hz at 12 UTC. He uses no balloon today but is visible in "600" anyway, the first time. 73, Stefan/DK7FC Am 08.02.2011 14:03, schrieb Markus Vester: Jim, thanks for this interes
Hello Lubos, You don't need DHO38 for locking. You can use any stable frequency within the soundcards range. Since your TX signal was stable, you can use that signal and lock on! Then you are totally
Hello Lubos, Yes, it was. I am curious that Paul has received your signal, unbelivable! I have had local QRM to that time i saw, maybe this is the reason. Just try again. If you make a break for ID p
