[Elecraft] running an external amp?

[K6MR]

Not sure if you mean the KAT-2 or the KAT-100, but I drive both my amps 
with the KAT-100s in line from both radios.  I don't know how the tuner 
would know the difference between an antenna or an amplifier input 
network.  I just let the tuner cycle (it's real quick) using the tune 
button the first time I activate the amp.  Then use the keyer to tune 
with dits.
