[Elecraft] KAT500 Following K3 not always working

[Peter Chamalian W1RM]

I have a brand new KAT500 connected with my K3 and KPA500.  I've set the K3
CONFIG:KAT3 setting to KAT500Y but the KAT doesn't seem to always follow the
K3 when I change bands.  I make sure that when I power up, I power the KAT
first then the K3 and finally the KPA.

 

Is there something I'm missing?
