Hello Psn,

This circuit is to examine and say what you see wrong.

below is the link to the schematic of the circuit now
in use at gva.

You can see the final signal results as posted to my personal site:
http://gmvoeth.home.mchsi.com/index.html
This is an extremely noisy location.
A low income neighborhood.

there are no bypass condensers within the schematic
but these bypass condensers do exist within the actual circuit.
They are a must to keep out electrical disturbances
such as shredding papers on the same power circuit.
Lightning will show as glitches even with the bypass condensers.

I have surrounded the circuit with thermal momentum
in the form of new soup cans full of soup, in this way
I kill two birds with one stone, store food and dampen
temperature changes simultaneously. The metal cans
may help to shield out RFI as well since they all
sit upon a rather large aluminum sheet metal ground.

feel free to download the images in any one of
a variety of forms.
All images together as a self extracting archive EXE form.

If problems please let me know at:
gmvoeth.NOSPAM(at)gmail.com.INVALID

I think you know what to do to get the right address.

Regards,
geoff
