[Elecraft] Digital mode power handling for KAT3

[David Gilbert]

Not really.  He asked about the KAT3, not the K3.  The KAT3 can handle 
some very wide impedances, but the question is can it handle full power 
from the K3 when it sees a high SWR at the output.  For example, how 
much power can the KAT3 handle for 10 minutes when trying to match an 
SWR of 10:1?  Maybe it can handle 100 watts for 10 minutes at that kind 
of SWR, but I can't find any spec that says so.  The KAT3 manual is an 
assembly manual only.

Due to the duty cycle of most digital modes, most, if not all, external auto tuners are "de-rated" for digital modes.  I haven't been able to find any reference to this for the KAT3.  Does anyone know the power handling capability of the KAT3 for digital modes?
