Look at today's quakes --
See all six Alaska and  Illinois unfiltered  http://Dad.bachcottage.com/June
28/raw pics&data . The more intense Illinois quake seems more distorted,
even on the homemade vertical and Lehman's while not so on the Alaskan
quake. If I am doing the filtering right, it seems to filter out on the
homemade vertical and Lehman's -- see files unfiltered-filtered in same
folder. If you have time,  look over this folder -- and any other stuff on
this disk you have time -- I even enclosed raw data and individual event
files. All electronics are yours. I did remove the jumpers on the amp board.
