Hi Jón,

Besides your timing make sure your latitude and longitude are correct. This 
information is also used by WinQuake to calculate the correct P and S locations. I 
see from your event files that you have your latitude set to 65.4N. Is it really 
65.400N? Once you get your GPS receiver you can use it to get your sensors location 
to 5 or 6 decimal places. You will need to let WinSDR average the data from the 
receiver for a few days to get this type of accuracy.
