The start time on the Z channel does not match the other two event files. If you look 
at the time information dialog box for the three files you will see that the N and E 
channels have -0.06 seconds in the time offset field. The Z channel has 0. If you 
change the Z channel to -0.06 and save the file you should see the two event files 
when you use the Add dialog box. You are having this problem because you do not have 
your WinSDR settings the same for all three channels. I think if you look at the 
Filter Delay number in the Channel Settings dialog box you will see that they are not 
the same. If you set your Z channel to 60 milliseconds like the others you should be 
able to create a three channel volume set. But rather then do is in WinQuake why not 
have WinSDR create the volume set? This is done using the Dataset Volume Control 
dialog box. Use the File / Dataset Volume Control menu items to open this dialog box.
