Something is broken.  I get 500W out on 6M (the most difficult band) 
with modes like JT65, ISCAT, and FSK441 for  48 seconds on each 
transmission; typically the fan will crank higher after 35-40 seconds.  
On the lower bands I run it at 600W on JT65 and RTTY.  I also had a beta 
unit for a RTTY contest weekend, with instructions to "run it with all 
the lights lit."  Never any problems.
