Hi Stefan, very nice result! Your spectrogram also contains 60 Hz from America, not too conspicuous but easily visible with a little visual averaging. 73, Markus (DF6NM) --Ursprüngliche Mitteilung--
Stefan, my impression was that ELF levels were slightly stronger in daylight; for the 60 Hz "TA slot" this seemed to be during our evening. But the diurnal differences were not large, maybe 2 or 4 dB

Hi Joe, of course we're watching! Think that I actually caught each of your Op transmissions between midnight and 7:33 UT. Average-power SNR's were in the minus fourties; might have really been a bit

Hi Stefan, Mike, here's what appeared from both of you in Nuernberg. This is a collage of ten half-size grabber screenshots between 16:30 and 19 UT, with colours swapped around to increase the bright
Peter Martinez, G3PLX, made me aware that the fourth transmitter in the Russian Alpha Navigation system is currently on air. Indeed dashes from Revda are visible on a colour-df spectrogram in purple
Hi Warren, shifted the microHz slot on my grabber to your frequency, but unfortunately no clear trace became visible yet, Considering low Loran-C levels from East Asia (Pohang, Helong), conditions ma
Hi Laurence, great! This looks like a good opportunity, which may hopefully raise some activity on this side of the sea. Please advise what RX conditions are like, and when you will be listening on w
Laurence, fine! Will try to get on 136172.5 DFCW, starting sometime around local midnight. Hope that others will go along - Stefan how about sparking up the well-proven Heidelberg lighthouse again? 7
Today I have been checking out all my LF-grabber bookmarks, and got this list of links: df6nm.bplaced.net/LF/LF_Grabbers_status.txt 17 active 137 kHz grabbers which updated today (Nov 8th), 4 entries

Hi Domenico, yes these are valid identifications. The 15:42 transmission from UA0AET was simultaneously detected by UA0SNV, JP1ODJ and JA8SCD, but you were the only one who managed to pick it up in E
Looks like the 135.77 kHz FSK signal from the Greek military (yellow strip at the bottom of my grabber) has disappeared since Nov 23rd, 22:11 UT. Does anyone in the group know whether this is a tempo

Hi Warren, last night between 21:30 and 8:30 UT, a blue trace appeared exactly on 137779.8 Hz in the 438 µHz spectrogram. Between 4:30 and 7 UT, some hints of the QRSS modulation were visible in the
