Threshold Voltage. If you can't get the gate above the threshold voltage,
then you can't turn on the FET.   In your case, you need to be
SIGNIFICANTLY above the threshold, or mister fet's going to get nice and
toasty.

I would have a link to http://www.findu.com/cgi-bin/find.cgi?KC6ETE-9 here
in my signature line, but due to the inability of sysadmins at TELOCITY to
differentiate a signature line from the text of an email, I am forbidden to
have it.
