Hi all, Hereby i'm announcing the next EbNaut attempt for a longer night transmission, starting in a few hours: f = 8270.100000 Hz Start time: 22.Feb.2017 18:00:00 UTC Symbol period: 30 s Character
...delayed by 30 minutes :-( Start time: 22.Feb.2017 18:30:00 UTC 11h 12min is about the night time between Heidelberg and Moscow now. The delay and the later end of the transmission may already fa

GM Stefan / Jacek Successful decode in Northampton UK IO92ng. Message sent off list for confirmation. -- found XXXXXXXX list rank 0 reference phase 180 180 180 180 carrier RMS 6.366e-005 noise RM
Last night the noise was similar to overnight 13th/14th. So yes, maybe you have gained 3dB. thanks for the anylysis Paul! i was just about to write you an email how to do it (especially how to estim
GM Eddie, Jacek, Thanks for the decode, i confirm the message is correct ;-) With such long messages, a false decode that makes some sense becomes most unlikely. I would never send messages like 'h;?
and for the next step, maybe there is someone on the list who lives near the magnetic conjugate point from you :) this would probably be around africa jacek GM Eddie, Jacek, Thanks for the decode, i
Jacek, What about FR5ZX?!! Her lives here: http://no.nonsense.ee/qth/map.html?qth=LG78PU He decoded me several time on 475 kHz WSPR but this is another story. But it already confirms that he has a PC
Hi VLF, For some local tests i like to transmit the 2 character message that i already sent on 970 Hz 3 weeks ago. This time on 6470 Hz.... Such a short message with sch long symbols may be interesti
Hi Stefan, your message was decoded well from DL0AO cardioid data. Initially, the best decode appeared with a phase slope, -30 0 0 30. Entering a frequency offset of one FFT bin (+9.3 uHz), the blue
Hi Markus, VLF, Thanks for the information. Yes, something must be strange. Look on my results/attachments. I generated a local decode from the tree, of course with a big SNR. But the phase! I got no

Jacek, i confirm. Well done! Markus, the same decode appeared when correcting the phase, as you say. But when the phase is not stable due to propagation, it could result in a phase pattern that can't

VLF, I just saw the sunset arround at 19:22 UTC. I thought there is no reason at all not to transmit :-) Tonite i'll try 3 characters on 6470, which could be a new longest message for Jacek. f = 6470
Decoded the 20170607 message (message sent to Stefan for verification). btw this is not my longest message on 6470Hz, i've decoded the 7-character MARCONI message (normal decode published at the end

Hello Jacek, I confirm. All right about Marconi :-) This weekend i'll attempt a 100 char message on 6470. A new challenge :-) Thanks Paul for the decode. 73, Stefan Am 08.06.2017 12:01, schrieb Jacek
