Again "oo" copy until 12:5x UTC, here now back at 22 mHz FFT bandwidth. 73 and GL everyone, Wolf DF0WD / DL4YHF . P.S. Markus - I didn't hear Stefan on 144.060 MHz but keep sending occasional reports
Stefan Schäfer pisze: The link to the IEEE paper is very interesting as well! Maybe the scientists over there are interested to take part on the experiments? Do you know some of them? Maybe we can co
Piotr, I just saw that i misunderstood something: I do not need to include the reduced antenna efficiency since it is already included, since the calculation is for 1 A Antenna current, right? So the
Wow! Dear VLF, This was very nice to read. So many messages and so many positive receptions. I am really impressed! Many thanks to you all who have been active on this day, watching on 8,97 kHz, the
Dear VLF, I have updated my website at http://www.qrz.com/db/DK7FC with some photos and a short summary. If you are interested, take a look at it ;-) 73, Stefan/DK7FC
Hi Wolf, Yes, I've seen similar signal on my Toshiba Satellit laptop. I can't recall the frequency though. I traced it to be generated inside the PC, and likely to be a battery charger sequence. No a
Stefan - when is the 8th experiment planned for? :-)) - I got a couple of hours at dawn this morning to sort out the VLF receiver (SDR IQ)and noise mitigation here in AK before getting on the plane.
Hello Markus ! Do you think Stefan will transmit again or is the experiment over? Do you have any infos on this? 73 es tnx OE3GHB Gerhard Am Samstag, den 02.10.2010, 15:44 +0200 schrieb Markus Vester
Hi Piotr, Nice to see your good work again. Do you think it would be possible to present the plot with a logarithmic distance scale. It might also be interesting to try dbuV/m for the strength axis??
Hi Laurence, You know, it depends on the WX. Most people are interested in the weekend. So i try to do it on the weekend. Maybe i will do the 8th experiment in 2 weeks or so. I hope so. The wind is s
Latest update at 12:25: Kite still up. But at 11:38 the generator ran out of fuel, and Stefan's still struggling to start her up again. 73, Markus -- Original Message -- From: [email protected] Ma
Hello Piotr, Again thanks for your work. The comparison of the 3 bands is very interesting. If i include the reduced antenna efficiency it is anyway an advantage to transmit on lower frequencies, at
Running again. Signal strong enough for QRSS10, or at least 30 here. Cheers, Wolf . Am 02.10.2010 14:26, schrieb Markus Vester: Latest update at 12:25: Kite still up. But at 11:38 the generator ran
Daniele, the two carrier segments certainly look right! Only the frequency stepping at 11:20 and 11:30 has apparently been covered by noise. 73, Markus -- Original Message -- From: danieletincani@yah
yes. The rain has ceased, and the kite is going up well. Stefan had a problem in his "big" PA, so since 10:15 he is using about 300 W from the smaller one. Antenna current about 0.6 A. Frequency meas
Hi Stefan and VLF 'ers , Good copy of the signals of DK7FC, JN06HT>JN49CE = 627km (see attached copy) the error of frequency is due to the correction of the sample rate of SpecLab was not corrected o
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
16:45: Unfortunately the attempts to restart the generator have failed, so no possibility to transmit on 6470 Hz. Now Stefan is finally packing up and calling it a day. He is really looking forward t
