I do think i found the source of the problem, i think that the ampling
of the psnamp board was too low. I did change it, but i am not sure how
much i did change it, it has the jumper on and the gain is from 175 -
1750. I did turn them clockwise and i think the settings now at maximum
settings. I see bit more noise then i did before.
If the range of a 4,5Hz geophone is up to 640 km max, then i problay
will not have problems picking up most small quakes that happen near me,
or at least up to 200km away from me.
