Filling in the gap between DK7FC (136172) and R (presumably R7NT, 136173) for a while... 73, Markus (DF6NM) --Ursprüngliche Mitteilung-- Von: DK7FC <[email protected]> An: rsgb_lf_group <rsgb_lf

Hi Joe, problem on my side: The RX LO frequency is currently not Rb controlled, but steered and corrected by the phase of Sylt Loran-C which is being monitored on the same PC. Due to a file access co
Hi Alex, nice grabber, and also a great website with interesting explanations and pictures. One I especially like is http://rn3aus.narod.ru/VLF/vlf-wide-capt51-selfad.bmp, a spectrogram reminiscent o
Hi Domenico, LF, thanks for last night's notification about your Op-32 transmist activity. After I had updated the correlation search list (copy at http://dl.dropboxusercontent.com/u/26404526/callslo
...no mails for a couple of days - just the usual summer hole, or has Blacksheep gone offline? Nice DFCW activity from DK7FC every evening, apparently aiming for Tasmania again. Bombastic signal, as
Dave, following your notice I reactivated the WSPR-15 receiver, though I have little hope of catching Robert's signal in my noisy location. But Tom 'HUH appeared on screen so the setup still seems to
Stefan, ah, that explains it! I was wondering why your fieldstrength had dropped after you went up the band, thinking that my RX calibration had somehow gone haywire. Hope your PA doesn't mind the re
Stefan, will you continue to send DFCW 90 tonight? I could join in 0.5 Hz above you for a few hours. Folks, put your grabbers up ;-) current...) ...well after going through several billion cycles the
Thanks very much to Bill, Jay, John, Mike, and everyone else who might have been looking out for us last night. I had reerected the antenna for the first time after a few weeks, and it was good to se
Hi Eddie, LF group, it looks like despite very strong 50 Hz and 16.7 Hz harmonics, I can still receive useful ELF signals from my Marconi (currently only 3 m above the roof) with a simple BF245 sourc
Eddie, Stefan, yes I was surprised and exhilarated to find the Schumann humps along with the 82 Hz signal. The quest to see those always seemed like some kind of holy grail regarding low frequency wo

Laura, interesting. How often do those overruns occur? Wonder if you could upload a few megabytes of that 192k wav recording for us to look at. Best 73, Markus (DF6NM) (only Windoze machines here, mu
Hi Piotr, congratulations on those results from your ground dipole! In my opinion, it is somewhat difficult to estimate ERP directly from WSPR SNR figures, because the variations in skywave sttenuati
PS: Forgot to mention that you may also need to consider directivity: The broadcast station used for the measurement should preferably be close to one of the main lobes (ie NE or SW). If there is sig
Stefan, good signal as ever on 136172 kHz. It was also nice to actually hear some bits of aural CW on LF again, 136.5 kHz 20:13 to 20:22. Good luck, Markus (DF6NM) From: [email protected] DK7FC
Last night, Edgar J. Twining in Moonah, Tasmania has successfully picked up several Loran-C signals from the other side of the world. He was using an E-field antenna connected to his Excalibur receiv
Hi Stefan, guess it depends on what you want to achieve. Your signal strength is above average, and some dashes have already been detected several times in Tasmania. You may now be aiming to convey a
