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 than on monday
BTW, I am seeing quite two strong signals on 8970.2 and 8970.1kHz using an MSK locked SL .usr file. I assume these are locally generated rather than anyone TXing? My grabber is currently running and
OE5ODL is active today too. what is strange is that the 9kHz amplitude (both his signal and noise) seem to be much lower, while the gain hasn't been changed from yesterday (i've enclosed the 179uHz w
This was DK7FC's signal on Spectran in normal speed CW. RST 549 with me by ear. 339 here with a very bad rx setup (vy simple direct conversion rx). would be 5x9 with a proper rx. VY 73 Jacek / SQ5BP
You are correct about the Internet being vunerable but you forgot to mention Broadcast JAMMING which is a regular occurance when your information is not wanted. This renders the transmitted informat
Some years ago, we tried using a small loop to couple a Heyphone (4 W output on 87 kHz) into a running rail in a disused railway tunnel in the English Midlands (we had permission from the owners of t
What about a closed loop between two HV transmission line towers? [...] Has someone tried that before? :-) there was a vlf experiment done in the USA http://qru.de/w4dex-vlf.html , that used a big l
Nothing at all seen on 5170Hz from Stefan. Interesting result after such a good signal on 8970. over here it was much better than 8970. see the attached picture - almost 20dB S/N at 5170Hz i guess i
fine signal on 8970Hz in KO02md as usual. there is some noise unfortunately - the S/N could have been better. jacek Attachment: dk7fc_20110206_8970_1.jpg Description: JPEG image
Gas pipes are non-metallic I think? i think the high pressure pipelines are metallic. Not sure I like the idea of connecting many watts of VLF power into high voltage pylons or gas pipes. In the UK
trying to couple to large structures is an interesting experiment, both for receiving and transmitting (only by induction of course :). think about power lines, phone lines (but unfortunately nowaday
A trace of Stefan's signal on 6470Hz is visible in QRSS600. QTH Warsaw, Poland loc. KO02MD. During previous experiments it was much stronger. I am very surprised, since based on previous experiments
Stefan's signal is visible with abt. 10dB S/N here in QRSS600. QTH Warsaw, Poland loc. KO02MD. During previous experiments it was much stronger. This is probably due to higher noise levels, both QRN
Don't discount the increased interference from [...] exactly. i don't have much experience with lf, but i see a big deterioration of the noise floor at vlf. in december 2006 i could receive SAQ from
There are strange transmissions near 12.4, 13.3 and 15.6 kHz, narrow band, very strong here in Heidelberg [...] maybe it's TACAMO? although i thought they use higher frequencies around 20-30kHz VY 73
Hello Is anyone else transmitting on 8970Hz? I just turned on the computer, and had a nice carrier 20dB over noise, and then it stopped around 20:45 UTC. I see on the grabbers that Stefan is still tr
