Hi,

If I understand this properly, it sounds like you do not have the outer 
braid / shield of your cable connected at either end.  If so, then it 
should be but only at one end, the amplifier.  Having said that, since 
the cable goes outside, you should consider using a lighning arrestor at 
the amp end, just in case you get a hit.

Hope that helps.

Hi,



If I understand this properly, it sounds like you do not have the outer
braid / shield of your cable connected at either end.  If so, then it
should be but only at one end, the amplifier.  Having said that, since
the cable goes outside, you should consider using a lighning arrestor
at the amp end, just in case you get a hit.



Hope that helps.

The two colored wire is connected to the amp board properly, the same
goes for the single colored one. This happens also with a cat-5 cable
that is not screened, I was using that before I got screened cable. The
sheld it self is not connected to anything, since I can't connect it to
the ground, at least I don't know how to connect it to the ground. Since
I don't see any connection for it. I know that the problem is not in the
amp board. There are capacitors inside the geophone, I think that thease
are capacitors. I can ground the shield of the cat-5 cable. If I get
some instructions on how to do it. I can also replace the capacitors if
I know what to buy and how to replace them. I know about good electronic
store in Iceland that sells this type of items.

This spike problem has been getting worse since I got the geophone, it
was not there in the early start. In the past 2 months it has been
getting really bad.

Regards.
