Hi Antonio,

Very nice page ;-)  Rain, snow, sleet, and even hail have kept me from 
further testing here.  But I hope to catch the first break in the weather 
for testing quenching and such.

Very interesting about the peak voltage vs. RMS voltage thing and how it 
relates to streamers!

Cheers,

         Terry
