[Elecraft] KPA-500 AM Performance?

[Chuck - AE4CW]

We all know that in AM mode the K3 sets carrier power at 25% of the power set
with the PWR control.  Can anyone confirm that the K3 switches in the 100W
PA in AM mode when the PWR is set at 13 watts or greater even though the
actual carrier power is limited to approximately 25% or 3+ watts?  I hear
the relay switch when moving PWR from 12 to 13 watts, but I would like to
ensure that the 100W PA is actually on and the low power amp is not being
over driven when PWR is set to 32 watts (to drive the KPA500) while the
carrier drive is running at 8 watts.  At this setting the KPA500 carrier
power is about 125 watts and peak power hits around 500 watts or a little
less.  Just being extra cautious about the K3's low power amp I suppose!
