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.

Hi Stefan , all

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.
