Hi Chris

I have set the raw data on digital filtering, but that one is on 5.5Hz
but the online graphs are now on 4Hz. It appears that the noise is
somewhat above 10Hz (there is noise on 10Hz, but alot less then if i
record from 2Hz to 60Hz), maybe above 6Hz.  I just haven tested it
properly yet. I do not know how this filtering will effect my abliti to
detect earthquakes. But i hope that the won't be any effect of this in
regarding detecing earthquakes.
