K3 KAT3 power during tune?

k5oai
I see in the manual, under CONFIG TUNE
it says:
"Note1: TUN PWR does not pertain to ATU TUNE , which always uses 5
or 10 W and is internally controlled."

what determines if 5 or 10 watts is being used?

  I would think the firmware makes that
determination. It always starts out
using 5 watts and I see it jump to 10
watts just before finishing.

Hi Sam,

ATU tuning starts out at 5 watts. If a low SWR is located during the  
coarse-tune phase, we switch to 10 watts for the fine-tune. This  
improves SWR reading accuracy.
