[Elecraft] K3 2 meter capability: internal K144XV or XV144 transverter?

[Giulio Pico - IW3HVB]

I totally agree with this.
I've too noticed when running the XV144 at more than 10/15 W the xverter 
case get pretty hot.
The Elecraft guys btw are well known to be conservative about component 
choice, keeping well within the safe limits.
On the other hand, just to keep things less hot I'vee added a small cpu 
fan over the top holes (the ones over the attenuator resistors) to drag 
out the hot air.
Since then the case has been a lot less warm even at full output for 
some minutes.
To avoide excessive noise from the fan I've connected the Voltage supply 
for the fan at the 12T point, so it runs only when on tx.

These are my  cents on the matter... :-)
