I have changed about cable in order to block out electronic noise. I did
use screened cat-5 cable. I did change about the cable from the geophone
to the amplifer board. So far, this looks ok. But I did discover other
type of noise that I pick up on my geophone, but that is the intal
signal that GSM (Cell phone) brodcasts when they start calling out or
start resiveing a call. Where I live, the GSM network uses 900Mhz freq.
band. I don't think I can block that type of noise out from my
recordings. But I problay can minimise the GSM noise, I hope.
