Dragan,

Can I assume that you first tuned the KAT3 to the dummy load on 40 meters?

If you did not, then the L/C combination for the last antenna TUNE you 
did are still present, and will show an SWR with a dummy load.

Actually 1.3:1 is quite a workable load on any band.  The SWR does not 
have to be 1:1.  In fact there is a low SWR point where the ATU will not 
attempt to tune.

See the K3 manual page 22 and the CONFIG:KAT3 menu (K3 manual page 56). 
If you have the K3S, the manual pages may b a bit different.

73,
Don W3FPR
