Thanks, I will put up new pic this weekend I have already built a =
plexa glass box. It is air tight except for at the bottom 1/8 inch gap =
in some places. The box was almost as hard to build as the seismograph, =
but I can see the seismograph:> When I first got the thing going with no =
adjustment and gain at 2000. The noise was off the scale so I put in =
extra resistor to reduce the Gain a lot more. I don't know how much. Ok =
when you install SDR it takes about "just guessing" 60 sec to go across =
the screen then drops down 2 more times then clears and starts over can =
I change the time scale here this would make it so I would not see as =
much drift/noise??

I have a lot to learn so please be patient with me.
