The K3 automatically sets the correct carrier output level for AM -- approx. 1/4 the set carrier power.  Fiddling is really not required.

The proper way to use the radio into an amp, for example,  is put the radio in "tune", adjust the K3 output tand tune the amp to the desired PEP output level.  (And heavily load the amp, the the way).  When you key up in AM, the K3 drops the carrier to 1/4 the set power, which is the correct level.

The power rating on AM is by definition 100W PEP -- the same as SSB.
