Hi Stefan, EbNaut A new chapter of Ebnaut for dummies follows J I made a lot of tests during the weekend. Installed the TX in the same computer were the Rx is running The small signal into a few cm w

Hi Stefan Thank you for the detailed explanation. I prefer to understand the process rather than getting a working .usr So, excuse me again for dumming again J All understood about the length and rel
Hi Luis, your last-mentioned decimator and FFT settings are fine. I think the confusion is only about the term "width". The 438 uHz is the width of one single FFT bin, i.e. the inverse of the 38 minu
Hi Luis, As Markus mentioned... And see the attachment. In the example i set the sample rate to 44100 Hz. If you have a downconverter with an LO of 120 kHz, and expect a message on 137 kHz exactly, s
Hi Stefan, Markus, EbNaut Thank you for the detailed explanations. Now I really understand the configuration and how is related to bandwith and length of the recorded files. There is also a fixed tim
Yes Luis that scheme should work. The 10 minute interval for file generation is not hardwired but simply the scroll interval, as chosen in the "options - Spectrum display settings" menu. Each column
Hi Markus Noted Very interesting. So I can reduce the interval between generated files just changing the Waterfall scroll interval at a fixed value as 5 minutes for example I had it configured automa
Good luck Luis, Later, for a QSO mode, i would suggest rather to use 8K19A than 4K19A. As far as i understand this will have more 'coding gain'. As soon as it all works, it becomes quite easy. In Lin
Hi Stefan, Markus, EbNaut Sorry. Still no results. I keep dumming L Have tried different messages in 4K19A, down to one character and 3 sec per symbol Tx and Rx run on the same PC, so timing must be
Luis, The numbers in the exported FFT data look different here. Not sure if this is the reason. Thus i asked for the usr file of your SL RX instance. I could compare it to mine and may find a differe
Yes these look like dB's instead of I and Q pairs. I think you have to go to FFT settings and select "FFT Output Type: complex (real+imaginary)". 73, Markus --Ursprüngliche Mitteilung-- Von: DK7FC <s
Hi Stefan The FFT lenght is 32768 and the exported FFT bins are 16384. Anyway the .usr file is attached The signal is almost 20dB over noise at 5mHz bandwidth. Clearly visible and I can also see the
Bingo, Markus! I had it as amplitude only. Now changed and lets see if there is no other switch toggled the other way around J Big thank you 73 de Luis EA5DOM De: [email protected] [

Hi Stefan, Markus, EbNaut Confirmed Markus. After changing the FFT export files setting to "Complex (real+imaginary)" it decodes perfectly :-) I have learn a lot this days. Will be updating some help
Hi Luis, Congrats to your success. We're looking forward to your messages. Try to apply that 100 mW to your antenna. It is not unlikely that it can be decoded in DL! For example, try http://abelian.o
