[Elecraft] Re： XV-144 heat

[Johnny Siu]

Hi David,

If it is XV144, there is neither internal fan nor holes in the PCB beneath the fan area.  

For XV432, there is an internal fan plus holes under the fan area.

As I mentioned in my earlier emails in this forum, I need to modify my XV144 in the way similar to the fan + PCB arrangement of XV432 so as to solve the heat issue. 

Without these modifications, XV144 will be extremely hot when operating under the power output  20W SSB/CW or 10W continous carrier modes.
