Re: Solar and RF fadeout North Tasmania, Australia


 

Sabine,
Luke is using SDRc2RSS. It has a pull down list of ¡°Windowing¡± like filters. While using these filters can remove certain artifacts in a spectrograph they do so based on the fixed filter parameters. There is no operator control over what artifacts are removed other than knowing what the selected fixed filter filters. This is why I recommend turning Windowing or Filtering off especially when calibrating the system because they slightly alter the spectrograph signal. Perhaps eventually a smart AI filter could be more intelligently effective than current fixed filters. In the meantime finding and avoiding RFI, while unfortunate and difficult, is the best solution.?
Thanks.?
Larry K4LED

a quick side note: Your spectrogram looks like the FFT is working without windowing. If this is SDRPlay2RSS generating the spectra, please enable "Windowing" in the "Integrate" menu. You'll get a much clearer spectrogram then.
