Hoop - Something must not be cabled properly. I have the same setup - K3, KX3 on a coax switch going to the KPA500 and KAT500. I can operate either K3 or KX3 with or without the amp/tuner. If my K3 is powered off and I want to use the KPA500 with the KX3, there is no issue - I can press the OPER/STBY switch on the amp and it does what it is supposed to do.
I do not recall having to do any menu settings on either rig for this to work. Be sure you have stuff cabled EXACTLY as Fred’s book shows… Jim / W6JHB > On Saturday, Oct 31, 2015, at Saturday, 1:53 PM, Jim Hooper > <[email protected]> wrote: > > I have configured my K3 and KX3 as shown in “The Elecraft KX3 - Portable: > Going for the Summit” book that Fred wrote, the 2013 version.
