Here is a link to the schematic I am currently using here in Apache junction, I was just wondering possibly if there is anyone out 
there  interested in breadboarding and testing this same idea ?? It is only for P/S waves. My area is terribly noisy so I trust just 
about no signals I see here.

Tamati asked me to show him what I am using
so I told him to look here to find it.

Cheers :-)
