[Elecraft] Factory Power Calibration of the KPA-1500 - question

[James F. Boehner MD]

This may have been discussed already, but just wanted to confirm.

I had a number of questions, but I'll condense them into a few:  

How are the KPA-1500 power LEDs/display calibrated at the factory, and what equipment is used to do the calibration?

Second, in the case of using the amp with K3 and the KPAK3AUX cable, is there a point where ALC kicks in and decreases power output?

Thank you!
