Paul, Part of the problem could be the computers time being off. If you are using WinQuake, and if the station is using SDR (my data logging software) with some type of time reference (GPS, WWV or WWVB), you should see an (L) next to the start time in the event window. The L indicates that SDR was locked to some time reference when the event file was created so the timing should be correct to within a few milliseconds, Regards, Larry Cochrane Redwood City, PSN At 01:16 PM 5/1/00 -0400, you wrote: >Dear members: >I have received several event files for the quake we got here in >Newcomb, NY, on 4/20/00.
