Hi all

I am having a bit of a problem. I more often then not I get a one single
line spike into my earthquake recording, those spikes can be seen on my
online tremor plots. I wonder if there might be some explantion for
these spikes. The wire that i use to connect to the amplifer board is
near alot of electronic hardware, tv, vcr, sky digital box, subscription
tv box for local channel (is going to get removed soon), tvoadsl tv
decoder box.

Becose of my location, i can't change the path of the wire. If that is
the source of this problem.

Any suggestion on this welcomed.

Also, I am going to move to GPS time kepping tomorrow, so time errors
are history for me. :-)
