I don't use that mode and generally run no more 
than 40 watts on PSK31 with the K3.

But this statement below "The K3/100 has two fans. 
The KX3 has no fans. Apples and oranges." made me 
wonder if fan failure could be an issue with the 
K3/100 -- and one which might affect those running 
less than 100 Watts.
