Hi Stefan , all
using Spectrum Lab recorder for EbNaut is sure a more convenient procedure becouse you have to use just the simple commands:
" wave.record" or "wave.stop" in the "Scheduled Action" table to start and stop the recording at the time needed.
If you want to produce a recording file, for example, every 15 minutes, you can put the only command "wave.record" in the "periodic action" menu. This command is able to close the previous .wav file and open the new one exactly at the period of time chosen.
In my experience, using Spectrum Lab recorder for repetitive recordings, the only small problem noted is that the initial time of the .wav file is always different of some milliseconds (maybe this depends from my slow Pc); so i need a small adjustments at the start offset in EbNaut-rx program for every file to be decoded.
I invite you to test one of the two .usr configuration prepared by Wolf included in the examples of his latest Spectrum Lab release.
One is for managing the I/Q signals of an SDR receiver. The other can manage the real audio coming from a traditional receiver.
I think that Riccardo iw4dxw and Michel F5wk are using the ebnaut SDR configuration, and according to their reports seems that it works very well.
I'm using the second .usr for the real audio. It works but i have experienced always a lack of 5-6 dB in the EB/N0 of the signal decoded with .wav files generated with this method respect to the same signal decoded using the .wav files generated with the DF6NM's (inverse FFT) method within the same Spectrum Lab session.
There are for sure some wrong parameters in my setting.
I hope in more EbNaut transmissions on-air so i can test better the settings comparing the results of both methods.
All the best.

Domenico, iz7slz

Hi Domenico,

Did you ever use the SpecLab internal decoder? As far as i know you need to know and configure the start time of the transmission before it starts. Can you confirm this?
I would recommend to record files for an eventual postprocessing. I'm (still) using the method which is developed by Markus.
I could explain this method to the newcomers but if the other method is easier to understand and more comfortable and more flexible then this may be preferred.

Hi all,

Just for start, there are some very useful   notes written by Wolf (DL4YHF) on his site regarding EbNaut  recorder function of Spectrum Lab

http://www.qsl.net/dl4yhf/speclab/EbNaut_Rcvr.htm

By the way i'm  also thinking  to write some operative notes, or at least, to describe my setup,  hoping that can be useful to other OM to enter in EbNaut.

For the moment i'm at disposal to assist  by email.

Maybe Markus wants to give detailed instructions, otherwise i will do.

We need some feedback then from you.

I agree, wot he said.

I did look at Ebnaut last year and got totally confused so gave up straight away, especially as not many people were using it.
Now it's more popular it would be interesting to at least give it a try.

Have I imagined it, or did someone post a guide, or a link to a guide,
for setting up Spectrum Lab and Ebnaut? Happy to just try reception
for now, what are my basic hardware and software needs please? I think
more would try it if a definitive pictorial guide to the process
existed. Thanks.
