Hi  Folks,  I have a Lehman set to 20 seconds..........It seems to be =
working okay and I don't think it needs any modifications.  It records =
the same as other Lehmans I have worked with.

I plan on changing the period from 20 seconds to another number, not =
sure what that number will be.   What I want to see, is how it records =
at different period settings.

I know the advantages of the 20 seconds.  The disadvantage is it misses =
many other smaller earthquakes.

My question:  Before I try other period numbers..........Have you tried =
this, and what were the results?

I really don't know what the result would be.
