Ahhh, O.K., with my 13.2v Astron it's showing 10.3 - 10.8. I guess for now with this power supply I'll have to settle for 5 watts. Thank you for the quick reply.

Set the display to show the power supply voltage and watch it while you 
transmit. The transmitter requires a voltage over 11 V for more than 5 W.

If the voltage is dropping below 11 V, that is the problem.

This in the specifications section of the KX3 manual.

    Hi folks,

      I'm running FT8 with a KX2 powered by a power supply. The rig keeps 
folding back from 10-12 watts to 5 every time and it's barely even warm.  I'll 
set it to 12W for instance, it'll transmit fine at that level but when done cut 
back to 5w. I don't transmit often enough for it to get hot enough to protect 
itself. AGC is off. Any ideas? I appreciate any feedback.
