Hi all

I did remove the plastic bags as Chris Chapman did advice me, but i did
also move my geophone back inside. Becose the noise inside the house is
less then the noise that is outside and the house also tamper the wind
noise down alot. I have been wondering about lowpassfilter and
higpassfilter, i do know where i can detect the earthquakes. But that is
from 2Hz to 10Hz that can work for me. But i don't know if they
lowpassfreq cutoff is 2Hz or 4Hz and other way around regarding the
higpassfreq cutoff. I have been reading help for winsdr regarding that,
but i don't understand what is what.
