Hi Greg,

  I cannot help you with Mathcad, but I do have a utility program that plots 
WinQuake Type 4 files in heliplot format. Go to

http://www.jclahr.com/science/psn/mcclure/wdq_utilities/index.html

and download "seismic_dataq.zip". There is a program in the ZIP called 
"WQFilter.exe" and its help file "WQFilterHlp.txt", which you could try if 
you wish. If you should want to be able to plot files longer in duration than 

6 hours, let me know. It is possible to convert PSN Type 4 format files to 
WDQ 
format, and I have a program called "Heliplot.exe" which can plot any 
number of hours of WDQ format data.

I've tried everything I can think of, but I can't get
a nice helicorder output for Mathcad.  There seems to
be almost nothing on the Mathcad site or on the
Internet about doing this. Any suggestions? Greg
