[Elecraft] XV-144 heat

[David Pratt]

A fan fitted inside the top cover sounds a good idea, Eric, as this 
would save having to drill a series of holes on the printed board as I 
have done. However, you would still need to drill some holes in the 
bottom cover.  You can't really draw air out if there is nowhere for it 
to go in.

Having fitted the on-board fan, I have just tried running it at 10W 
output for 30 minutes on a dummy load.  Warm air is coming out of the 
top vent holes and, taking to top cover off, the PA module is warm to 
the touch, but not hot.
