[Elecraft] FSK power

I've become a firm believer in air flow during rtty contests.  I use a 24 
volt 5 inch muffin fan
blowing air down into the K3 across the PA fins.  I run the fan with about 
12 volts which
cuts the noise down somewhat.  Looking at the PA temp while doing this, it's 
hard to get
it up much over 35C during a contest.
