Hi EbNauters Finally running here an E-field probe connected to the soundcard and 1pps disciplinning VLF signals are weak but I can see 11.904 Alpha at 374uHz stable and right on frequency What I sti
Hi Luis, the attached usr is similar to what I'm using here. Notes: - The data files (named MMDDhhmm.txt) will be written every hour into a folder "data8H". You will first have to create this folder
Thank you very much Markus The .USR file is useful, but your detailed explanations are even better to understand what's going on Would worth to add it to your EbNaut utilities So far so good. SL is "
Hi Luis, What is the link to the grabber (again) please? Something with ure.es i think... I would prefer to run the soundcard at 48 kS/s anyway because you will be able to run much more SL instances
Hi Luis, On the air again here. I also found the link to your grabber, https://ea5dom.ure.es/grabber/index.html I would suggest to run a spectrogram showing 0...24 kHz, scrolling at 1 minute /pixel.
Hi Stefan, VLF And thank you for your all your comments and advices :-) I was already running an SL instance showing the first 24KHz in a fast way to get an idea of what's going on with QRM and known

Hi Stefan The grabber is now showing full spectrum from 0-24KHz https://ea5dom.ure.es/grabber/index.html The Rx is not at Benidorm in the high tower. It is in the roof of a two level house on top of

Hi Luis, > BTW. What I'm getting from SL is one FFT file 112Kb size every hour as Markus said > But how can I merge all the files of a 8h transmission like the one your are running now ? Each of thes
Hi Markus Thank you again for the detailed explanation To try a decode from Stefan transmission yesterday at 18:00 I have choosen the file 05022225.txt This should contain the 7.9h FFT from 17:58 to
Hi Luis, confirmed, running EbNaut v0.7 with 05022225.wav crashes here too. The reason seems to be the date and time format in the timestamp at the beginning of the 05022225.txt file. The first two e
Hi Markus Not your fault ! I did not use your .USR directly. Tried to reproduce the configuration manually Then I did not realize about the different time pattern in the files. Now I understand one m
Hi Luis, yes I also found that your file starts 20.76 seconds late. But this is not a big problem, because the decoder can cope with missing data at the beginning or end. For a late start you should
