Kevin -


Don may be correct in this case.  I have not seen a K2/100, and if 
indeed air is already being directed through the heat sink, then you 
certainly don't want to set up an opposing airflow.  Does the K2/100 
heat sink have holes?  How does the air flow from the internal fan reach 
the heat sink?  My example, in my last message,  is for the general case 
where there is little or no air directed to the external fins of the 
heat sink.


My K2 is the basic version, no amplifier included. The photo of a K2/100 
on the Elecraft main page does not show how the air from the internal 
fan is routed, and the internal photo of a "folded out" K2/100 is not 
much more help.  I can see the fan in the photo, but that doesn't tell 
me much.
