I too had a close event the other day. The event was a MD2.2 right here in Redwood City. The non felt event was ~ 4km or ~2 miles from me. I think this is the closes event I have ever recorded. I was lucky to record it on all of my sensors. I just got done with rearranging my station. The even happened only 15 minutes after I got my system back on line. Recently I added a second channel based on the IDS3052 accelerometer chip. This channel is oriented vertically and it recorded the event very nicely. The event file is 011027.0618.lctsz.psn. Here's an update on the new accelerometer sensor board based on the IDS3052 chip. I hope to be selling it soon. I completed the PC board layout last week. I should be getting 10 PC boards in a few days. Once I verify that the board works, I will be sending out a email message to the list as well as make a web page documenting the new product. -Larry Cochrane Redwood City, PSN ----- Original Message ----- From: "ian"
