[Elecraft] KAT500 Matching Range & Power Limits

[Ed G]

Hello,
     I'm trying to understand what the KAT500 power limits mean in real
life.  If I am tuning an antenna that initially shows a very high SWR (say
14:1), and I am using high power (say 1000 watts out), the KAT500 is going
to open up the PTT line, and the tuning operation will take place with less
than 100 watts.  Then I will show a 1:1 SWR, and I'm ready to go with my
1000 watts.  Operationally, what is the meaning of the 3:1 SWR limit for
1000 watts as shown in the KAT500 specs?  Will the KAT500 fault because it
is matching a 14:1 SWR at high power?
