Thanks Jacek,I confirm the message you sent to me in a separate mail. My congrats. So 30+ characters would be no problem in one night. Luis, has already shown the message, so it is no secret :-) On my own grabber (which is still running), http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html the signal level is equal to that of GBZ 19.58 kHz ;-) But the distances are a bit different ;-) I can hear the signal loud and clear in a comfortable CW filter. It is at 35 dB in 366 mHz (without a NB) here in 3.5 km distance, which is the far field already :-) 73, Stefan Am 09.12.2017 13:53, schrieb Jacek Lipkowski: Stefan's transmission on 20171206 22:00 17470.1Hz:found rank 0 ber 2.2135e-01 Eb/N0 11.2 M -1.417898417e+00 [***] ps [104 -60 -30 -30 0]carrier phase: 9.6 deg carrier Eb/N0: 12.0 dB carrier Es/N0: -4.50 dB carrier S/N: 24.35 dB in 32.6 uHz, -20.52 dB in 1Hz, -54.50 dB in 2.5kHz elapsed 1187And right now Stefan is almost overdriving my grabber (note that the amplitude scale is set manually so the max amplitude is bigger than what is presented on the scale):https://klubnl.pl/wpr/en/index.php/klubnl-pl-grabbers/tymczasowy-grabber-sq5bpf-do-testow-stefana-dk7fc-na-17-4701hz/1.2A seems to be doing it's job.
