Take this advice train the Tuner then run it in MAN mode I use my KPA500 
and KAT500 with both a K3 and a IC7610 all I have to do when using the 
Icom is tap the key in any mode send RF and the Tuner changes to the 
memory it has in store for that segment of the band and antenna.

This is for the none Elecraft radios when using the Icom I *REMEMBER* to 
have drive power set and the amp is in STBY. Set the KPA500 menu for 
standby when power up or changing bands good insurance.
With the K3 the freq info is automatic ...again do not run the KTA500 in 
AUTO mode it takes very little power for the tuner to see what is going on.

My reason for running it in MAN mode is if the weather changes my wire 
antenna impedance Auto mode *might* try to re tune hot switching it.
