I don't think this is so simple. May be a quark in the software in reference 
to the location here in midwest -- too close to 180 degrees. There is no 
doubt that I got a good record. The arrival of Pdiff appears the same as on 
the local university helicorder and if I try to place Pdiff and S manually, 
I can get phases to come in (if I use the locate feature in conjunction) but 
if I move S  one way or the other just a little everything disappears..I 
even processed a 2.4 locally about twenty minutes before with no trouble. So 
Larry's program works fine!
