Hello Stefan, VLF,

 

Paul Nicholson (on his web page about his great work on data from Stefan's recent experiment) writes:

 

Best results were obtained with the loop antenna oriented towards DK7FC (rather than oriented to null the average background noise). Sferic blanking made a useful reduction in background. The signal was band-limited to 6-12kHz before applying blanking with threshold equal to the mean amplitude and no dwell time. Blanking was activated approximately 60% of the time and effectively removed all non-Gaussian noise components.

I would like to apply spheric-blanking on recorded data by using SpectrumLab. How do translate Paul's indications in SpecLab blanker parameters, I mean how should I proceed in practice to set the blanker thresholdto the mean amplitude with no dwell time?

 

Many thanks to all in advance for suggestions.

 

Best regards

Daniele
