Hello Mark,

Most of what you describe is quite possible. I think that the all the
PSN stations that have permanent connections to the internet accurate
time and a known locations could contribute. It would also help if the
polarity of the signal was correct and finally if the transfer
function was known. I think we could locate events with seconds with a
loose network.

All of the code is written and free all we have to do is assemble it
and make it work.  I'm interested any other taker on such a project.
I was going to propose it in a week or so anyway.

Happy New Year to all.

Best regards,

angel

PS Mark, tell me more about the relays, I might want a bunch.
