That is very nice. Herzlichen Glückwunsch an Stefan! This evening I will analyse the signal further - it is very faint and may not have much significance (statistically) but is nice to see and most
This is amazing stuff and congratulations to all concerned. When the tests are finished, please can we have a summary of the details here i.e. distances, power, antennas used etc? 73s Roger G3XBM On
Paul, QRSS10 dots means 10 sec radiation then 10 sec pause. Then again 10 sec radiation and so on. I expect when signal was not broaded at the begining it was Stefan's tuning. After 16:30 as Markus m
Yes, the signal was too wide, except during the initial tuneup when the pure carrier sat nicely inside one frequency bin. I should think so. And still easy to read from the spectrogram. And gain mayb

Dear Stefan, Paul, LF Group, I would agree that something like DFCW100 or DFCW200 with about 0.1Hz shift would be a good candidate mode for further DX tests. DFCW is about 2 -3 times quicker than QRS
Such scepticist you are, Mal. Any data can be analysed. By the way frquency is some ID by itself. And certanly we are looking for more proof. Regards, Alexander
Paul, Stefan's signal is clearly there on your spectrogram. WOW! A dream came true. Markus --Ursprüngliche Mitteilung-- Von: Paul Nicholson <[email protected]> An: [email protected] Vers

If you go the the extent of UT synced FSK, then you'll gain another 3dB by using BPSK. FSK is an orthogonal signalling mode, where you test the power level in one slot (frequency bin) against that

Well done, and congrats to everyone involved in the 8.97 kHz test ! The spectral spreading in Stefan's signal looks similar in Todmorden and Nuremberg, maybe the TX has been turned on and off with a
