Howdy -

Some of us are poor, so we can't afford a fancy oscilloscope.  Here's 
a link to a pretty nifty software version that works with your sound 
card: http://polly.phys.msu.su/~zeld/oscill.html.  I have no 
affiliation with this site or the author, I just did a search on the 
Web.

Turns out my calibration wasn't too bad!
