Hi LF, I'm on air EbNaut every 30 min. with these parameters: QRG: 137485.0006 Coding: 8K25A Sym. p.: 2 sec. Length: 6 char Duration: 20' 16" Thanks for reports! All the best 73 de IW4DXW Riccardo P.
Warning: it will take about 20 Gbyte RAM to decode 6 chars. About 5 Gbyte for 6 chars with 8K23A. 8K21A about 1.2 Gbyte is a good choice. -- Paul Nicholson --
Thanks so much, Paul. Sorry! Ok, 8K21A confirmed for next transmissions. Duration: 19' 12". 73 de IW4DXW Riccardo Il 09/Feb/2017 22:16, "Paul Nicholson" <[email protected]> ha scritto: Riccardo wro
Tried 8K25 first but it immediately froze my PC, requiring a hard reset. The 8K21A message starting 21:30 decoded fine. Good luck! 73, Markus (DF6NM) --Ursprüngliche Mitteilung-- Von: Riccardo Zoli <
Thanks for report, as usual. In my case the BPSK modulation is simply obtained by a CMOS XOR port, in fact the bandwidth on your grabber seems larger than Domenico's EbSynth test signal. Now I'm put

The ebsynth settings Domenico is using produce BPSK where the phase is slewed from one polarity to the other. It takes 0.05 of a symbol period to change phase. This is intended to limited the keying
Nice decodes from IZ7SLZ as well - here's one from the morning with very slightly positive Doppler. Wonder if VO1NA was listening? To verify frequency calibration, a couple of nearby Loran lines from
Hi Domenico, great signal again tonight! Best 73, Markus --Ursprüngliche Mitteilung-- Von: IZ7SLZ <[email protected]> An: rsgb_lf_group <[email protected]> Verschickt: Fr, 10. Feb
Hi Domenico, Markus, I was QSL last night and will be trying to decipher the files. In the mean time, I'll be happy to upload a selection from the following: 10/02/2017 00:50 1,722,763 02100023.txt 1
Hi Joe, many thanks for the news and for listening last night. I think that these are the files to upload : 02100043 02100113 02100143 02100213 02100243 02100313 02100343 02100413 02100443 02100513 0
Hi Domenico, EbNaughters, They are there. Thank-you for the signals and good luck with the processing. 73 Joe Hi Joe, many thanks for the news and for listening last night. I think that these are the
Hello Joe, LF Analisys is started here but i have some problem to found the pilot tone. I found a carrier at 137500 + 0.097 Hz with a good amplitude on 021000043.txt file. I suppose this is your ton
Hi Domenico, as far as I know Joe's not using the pilot for SpecLab frequency lock, because we found that the level required for this purpose would be so large that it affects SNR. But the weak tone
Version 0.7 of ebsynth is available, http://abelian.org/ebnaut/ebsynth.shtml It fixes a few bugs and has options to drive the PTT via DTR and RTS of a serial port. During testing I actually managed t
