Hi Domenico,

Which filter settings did you choose to obtain the CW filter?

I also used vlfrx-tools to extract the SAQ message. The SNR was much
stronger on the N-S loop than from the E field. Mixing E and H
(including a small portion of the E-W loop) resulted in an SNR increase
of > 6 dB.
But in the end i used SpecLab to build the CW filter, a rough noise
blanker for the very loud sferics (12 dB threshold) and finally a slow
AGC which made it even more comfortable to listen to...

73, Stefan
