Hi Markus and Paul, Congratulations to this remarkable success! It seems almost impossible that this is possible ;-) Now we know that many amateurs could get a reception of their signals, transmitted
Dear VLF, This weekend i plan to do my next kite experiment. I have got the permission for a kite ascent up to 300m above GND on my QTH in JN49IS36VH. I will be QRV either on saturday or on sunday, d
Dear VLF, So, now after another very successful VLF experiment i want to summarise some informations and achieved results. First i want to thank all those who did and tried to receive my VLF signals
Hello Roelof, Sure, here it is. I have added another one which is suitable for 6470 Hz! A third one is suitable for 5170 Hz. It has an extended frequency range (thus, DFCW-600 is not readable, so i w
Dear VLF, Just before some minutes i acidentally clicked "sort by date" in my email folder and found the oldest emails of my VLF folder on the top. See those historic 3 emails out of february 2010, b
Hello Gary, Tony, VLF, Yes, you can use Markus' files for reception. It is suitable for the detection of a long carrier, say 30 min. If you want to copy my DFCW-600 letters (10 minutes per element),
Hello Michel, Maybe i can try this at work. In some days i can tell you more. If others want my audio record, this will be no problem too. Tnx es 73, Stefan/DK7FC Am 03.10.2010 15:53, schrieb Michel
I've just analysed my recording of the 8th experiment, regarding an audible CW signal. Although the signal was well copied in 1310 km in DFCW-600 the is no audible copy in CW in 40 km distance, not e
I am pleased to have received SAQ the first time at all! Since i was not QRV on VLF last sunday i took a recording that is analysed now. SAQ is 40 dB above noise in 12 Hz FFT on my grabber. 73, Stefa
Thank you Alan for your reply. One more difficulty could be the different radiation pattern of the two configurations. So the signal difference at a specific location must be seen with care. If the s
Hi Warren, Tnx for the link, its interesting! Maybe i can get some ideas from that, hi ;-) NAA is well visible each day here. 73, Stefan Am 12.10.2010 16:17, schrieb Warren Ziegler: See the following
Hi Tony, Thank you. I am looking forward for that! Our distance is 1310 km (pic attached). Pse, what is your complete RX equipment? Do you have the settings for DFCW-600? Any noiseblanker and/or clip
Hello Wolf, Please become QRV on 137 kHz again and let us make a xband contact! If DFCW-10 is possible, this should be no problem! :-) Nice project! :-) 73, Stefan Am 02.10.2010 13:47, schrieb wolf_d
LF, G3XDV and RA3YO with O copy on my DX grabber. Mike is 30 dB above noise in JN49IK, Dmitry about 15 dB S/N. Nice, go on! ;-) GD DX! 73, Stefan/DK7FC Am 07.10.2010 20:18, schrieb Mike Dennison: Sco
Hello Jacek, Thank you, interesting! :-) I just saw that the signal on 8970 Hz is strongest at the end, means the last dash of the "M" while the 1 hour transmission is rather weaker. But my ERP must
Dear group, Does anybody know if someone from Iceland (TF) is QRV member of this group or are there OMs who are (or have been) active on LF? You know what i am thinking about ;-) 73, Stefan
Hi Alan, I want to try an alternative to the BF981 which runs in my current LF grabber RX. It downconverts 137 kHz to 12 kHz and feeds the soundcard with this 12 kHz signal. It is running not too bad
Hi Roger, Nice that you are back :-) I assume you will spend the night by reading the older LF mails? ;-) Yes, maybe this saturday but it's still uncertain, as usual... 73, Stefan Am 19.10.2010 16:54
