[Elecraft] XV-144 heat

[Eric]

My xv 144 has holes on both the top and bottom cover as it came from the factory

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.

This is odd because I drive my XV-144 with 1 mw as well, but at 10W output in digitial mode (1 min tx, 1 min rx) it gets way too hot to survive without a fan.  I have one screwed to the shelf it sits on that blows air under the XV-144.  Inelegant, but effective.  I would like to see a fan retrofit kit as well, perhaps inside the top cover that would draw air through the unit and exhuast it out the top.
