[Elecraft] Cooling on a KX2

[Howard Hoyt]

Hi Mike!,

You are of course correct, and there is no reason not to do so when 
operating fixed near AC power.  Usually the situation where people do 
not use fans is when they are operating portable and don't want to waste 
the power or have extra stuff to pack/set up.  This is the reason our 
heatsinks are optimized for convective cooling, but they can show 
extreme cooling gains when using forced cooling.

The reason we do not rate them with forced cooling is because the air 
temperature and speed are uncontrolled variables unlikely to be 
duplicated by users, whereas rating them for full convective cooling is 
much more conservative.

Cheers & 73,
