OK,
I found out that I put out too much power with my
XV144. This is because I did alignment with 12V and
later ran the rig with 13,8V.
I did two things to nearly solve the problem of
overheating my XV144.
1st I realigned power with 13,8V
2nd I disassembled the chassis, removed the heat
rubbers between the power module, heat spreader and
bottom cover. Then I applied heat-conductive paste in
both places.
So power is now lower and the heat is very much better
spread on the bottom cover. You can feel that.
Nonetheless, there is a point in time after maybe
15min of continous CW CQ where the XV shuts down due
to heat. But this is heavy contest use and a fan is
appropriate/acceptable in this scenario, I think.
