Hi LFers, My first EbNaut message is running at the moment. Not sure if the timing and keying is OK. Could someone check if it can be decoded? Don't make a secret out of the message. Parameters: 4K19
Hello Stefan, Glad to seek you again on LF and congratulations for your great job on ULF and VLF. I'm following your experiments with interest hoping to partecipate one day. Regarding today's EbNau
Hello Markus, Oh, you are right. Same message on 16:30 utc. .. I hope it works... 73, Stefan Am 18.06.2017 16:56, schrieb Markus Vester: Hi Stefan, I'd like to try. But the QRG 137.43 kHz was below m

Hi Stefan, a fine and error-free decode, best with 0.3 s extra delay. A phase glitch occured here near the middle, presumably on the receive side. Best 73, Markus --Ursprüngliche Mitteilung-- Von: DK
Thanks Markus, nice. We could exchange 1000 characters in 2 minutes, if the Eb/N0 calculation is correct :-) Maybe i will try another one with Domenico when he is back. And is RN3AUS reading this ema

Hi Domenico, Thanks for the detailed report and the EbNaut decode over 1159 km. It was still in daylight, so not bad for LF in mid June and a 376 second long message... Where does that -3.4 mHz offse

That is strange indeed. Maybe something is wrong here? Maybe the old GPS module is not running properly? I had to replace a mains socket recently and had to shut down the complete station for that. I
Hi Stefan, the frequencies of recent detections (e.g. IW4DXW) on our two opds grabbers seem to be within a mHz, so your 10 kHz derived receive LO should be ok. Could it be that the strong LF transmit
Hello Markus, Domenico, Ket's just play arround a bit more instead :-) It was such a nice day here, time for another message :-) f = 137.53 kHz Start time: 19.Jun.2017 20:40:00.3 UTC Symbol period:
Hi Stefan, Markus, Domenico, LF Vy strong here (as usual) in JN64bw, dr Stefan. Good decode: there is only a little phase rotation and I see you about 6.3mHz lower than your nominal QRG. All the best
Hello Riccardo, Many thanks for the decode! I would assume that the phase rotation is due to propagation. There is also QSB on LF, although not as strong as on MF. The Alps may add a bit more. 73, St
Hello Stefan, Here's my decode also. Found best results at same freq. offset of Riccardo. The small phase change is due to propagation. Thanks for the signal and thanks for your calculation of my 'si

Many thanks Domenico. I think that i found the bug in my configuration now! Let me try another attempt and let's see the offset: f = 137.53 kHz Start time: 20.Jun.2017 14:00:00.3 UTC Symbol period:
Hi Stefan, Domenico, LF Now it's perfect. Nominal QRG, no phase rotation ;-) All the best 73 de Riccardo IW4DXW Attachment: stefan.png Description: PNG image Attachment: stefan1.png Description: PNG
