Below is my contact email address:
--- Retirement --
Now that I am retired I am requesting that people use the PSN Mailing List for any questions regarding setting up a seismic station, building earthquake sensors and my software programs WinSDR and WinQuake. I am making this request for several reasons. One, you may get a quicker response and answers to your question(s) will get archived so others can learn from the answers. And to be frank, I am getting tired of answering the same questions over and over again...
If you are having WinQuake registration problems please see this link for more information. If you are unable to resolve the problem please use the PSN Mailing List for help.
Do to my retirement I am no longer selling earthquake recording equipment. I would like to thank all of my past customers for their business over the past 15+ years.

It was necessary to enable this feature since I receive over 70 SPAM e-mails each day! You should use this form if you received a bounce message indicating that the IP address used by the senders e-mail server was blocked by our e-mail server. You should also use this form if you have not heard back from me in a few days after sending me an e-mail message. It's possible that I accidentally deleted your e-mail message thinking it was SPAM.
