This is counter to what I had thought! But:

With external 13.8V input, power lowered to 5W at 3 minutes 48 seconds.

With internal battery, I gave up at after 8 minutes, with PA temperature
at 60C.

Maybe a new KX2 11V power supply is needed for dx-peditions similar to
Linas' adventure to Aland Islands.
