Hello Dick,

I took a peek at most of the seismograms on your page and with the
exception of the one in Costa Rica I really could not see anything.

I don't see how you could get SDR to trigger on those signals.

I would say things are not right, I can't say what off hand. In the CR
set I don't see much difference between the lehman and the geophones,
maybe use a bit of filtering.

With your lehman are you able to see something around six seconds,
you should. I think that that would be an indicator that your long
period device is more or less working.

As I recall you had some pictures posted of you lehman, are they still
up? What is the setup of you different stations?
