It works VERY well. Long before I bought my KPA500, I beta tested it 
during a RTTY contest. My instructions were to "run  it with all the 
lights lit." It produced full power for the entire contest, even when 
things slowed down at the end and I had to CQ constantly.  Yes, the fan 
speeds up, but I've never found it to be a problem, because I nearly 
always contest with headphones.

The most demanding condition I've found for the KPA500 is keydown 
digital modes like JT65A on 6M, where you're transmitting for 50 seconds 
at a crack. The fan speeds up a bit near the end of each TX cycle, but 
power out remains at maximum.
