[Elecraft] KX2 output power drop

[Don Wilhelm]

Pierre,

That may be normal behavior, the power will drop to 5 watts if either 
low voltage occurs or if a high PA temperature condition occurs.

If you are operating digital modes, I suspect that the high PA 
temperature is causing the drop in power.

Check the BAT MIN setting in the KX2 menu.  See page 43 of the manual. 
The proper setting varies depending on the battery type, and the default 
is 10 volts.
