Hi Dick, The K3 uses either 5 or 10 watts to tune the internal KAT3 tuner. Mine uses 5 watts and I'm not sure under what conditions it would use 10 watts. You can see the tuning power used briefly displayed in the VFO B area when you tap the ATU TUNE button.
By the way, the TUN PWR menu doesn't affect the power used when tuning the tuner. It sets the power output when you hold the TUNE button.
