Hi John and Others, We all heard about the 6.7 SAMOA ISLANDS REGION at =
28 Sep 2006 06:22:11. After checking my station first thing this =
morning, "Like a kid on Christmas morning" I saw a signal, or what I =
hoped was a signal. I checked the internet and found this 6.7, was in =
the same time area. I was able to expand my trace and look for the P =
and S......I use local Helicorder and PSN's from the net so I could look =
for similar parts of the event, not really knowing where to start. My =
station is primitive but I am improving it everyday. Working on a new =
Amp and Filter. If someone has some free time to correspond with me on =
this issue, please email me and I can send screenshots of what I did and =
where I think the P and S are. I am a bit confused because the P look =
like the same time it should have arrived, in Boise, but what I think =
is the S is too early. Where the S should be, I don't see it. I don't =
wish to bother the group, but if someone would like to help me, I would =
be grateful. Anyhow I think I recorded my first Earthquake.
My wife was not nearly as impressed, as I was.
Thanks, Ted

Ted,
Larry Cochrane has given me permission to post his seismic =
amplifier/circuit, which is a well designed and proven to work well.

The easiest route is to purchase one from Larry: =
