Apparently my subscription to the mailman list got lost, so this is a second
attempt to get this query out there:

First, the Rev C. manual says the following: 

/The Elecraft KPA500 is designed to have its key line switched to disable or
enable the amplifier even 
while it is producing full RF power, but many other amplifiers may be
damaged doing that. To protect 
those amplifiers, the *KPA500* is supplied configured so that the key line
will not be switched if more than 
29 watts of RF power is present./

I am guessing this paragraph should say "the *KAT500* is supplied
configured....."? 

I am getting close to ordering the KPA500 and KAT500 to go with my K3/100
and the tuning process is not clear in my old brain yet.  The manual states: 

/A tune operation begins when RF power between 10 and 100 watts is applied
and the SWR is above the 
tuning threshold in AUTO mode, or when the TUNE switch is tapped in either
AUTO or MAN modes./

I am not able to fully grasp how this all works.  Part of my confusion is
the upper limit of 100 watts.  Typically I will run the amp at more than 100
watts driving into the tuner.  What am I missing?  I hope tuning is
automated such that all I have to do is key down shortly (a dash at 30 wpm I
think I read somewhere) and the tuner will kick the amp offline if retuning
is needed, do the tuning, and kick the amp back online.

Any comments will be appreciated. 

Chuck, W5UXH
