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.

Hello all, Well, I cannot say that it is a high SWR, but when I connect my K3 to dummy load it shows 1.3:1 SWR on 40M. All other bands 160-10 are OK, 1:1. Other rigs shows 1:1 on 40M. Where to start to fix this?
