Hi Jim,

Happy New Year.

I have a few questions:

Do each of the stations have good GPS timing?
What is the sample rate?
Are you digitizing on site or transferring data to a central site with 
some analog scheme?
What is the protocol the digitizers use?
Do you plan to user array proceeding (fk) or just plain jane locations?

A fuller description of the system would help.

I wish I had my own array :)

Saludos,

Angel

Need EQ Location Program: 

          Recently set up and running a seismic array with 8 sites using
          3-C, 1 Hz geophones. 

          The area covers ~10 km radius with micro earthquakes (M<2)
          occurring weekly.

          I would like to find a simple location program: 

          to determine magnitude, epicenter, and hypocenter.

      Prefer
        program to be Windows OS, but will consider other systems too.
