[Elecraft] Successfully using a micro fan to keep K2 cool

[Don Wilhelm]

Phil,

Solder some wires to the terminals of D12 inside the K2 (the cathode is 
positive 12 volts and turns off with the K2 switch).  Make a small notch 
in the rear panel above the coaxial power jack sufficiently large to run 
the wires through would be my preferred routing for the wire, but make 
your own choices on the routing..

73,
