Hello Stefan, Very interesting received-signal spectrum images! Last night I was wondering what the receive characteristics of your ground-loop antenna would be, so your scope spectrum images are a n
Hello Joe, Fine signal! "What would cause a 180 degree phase shift? Is there an XOR gate in the sky?" Might we say "D" Flip Flop (comparatively slow rise/fall). Attached is roughly how the effective
The attached shows close experimental and theoretical agreement on an "attenuation summit" at ~ 17000 km at ~ 17 kHz; the hemispherical distance at which the signal is weakest, past which it is down
It looks like the SAQ received signal frequency ramps upward ~ 25 Hz (over the 16:25 16:45 UT period) at Edgars QTH. On Peters spectrogram I cant see a frequency change but the resolution of the spec
stabilized using an external PLL Markus, thats a really interesting idea. I wonder how well the conducted spectrum of an open-air arc could be managed by a few digitally controlled loops and all-anal
Hello Stefan, Good SNR at 3.5 km on the 1110 km band makes this a noteworthy day! During your future SLF pre-tests, and in the future tests that you mentioned with the ground loop transmitter, will y
Hello Joe, "... phase shifts in the fall were so close to 180 degrees... hope they come back " Annual repeatability of monthly-average daytime path delays (phase) is surprisingly good, but a two-mode
Hello Wolf, If I am treading on anyone's intellectual property please advise. Years ago I built a version of what you mentioned, and I don't operate it often because of fear of kinetic effects :-) Th
Hello Stefan, Paul and Markus, Nice signal and captures; based on SNR at Paul's grabber, would it be good to check westward paths? Mike's grabber? Not sure of my math but seems like SNR at Mike's gra
