I have noticed on my KX3 that the SWR indicator gets progressively less accurate on the higher bands. I have the antenna tuner installed, but when I put it on bypass, I see into a 50 ohm dummy load

15m 1.2
12m 1.4
10m 1.5
6m 2.1

I have used two homemade dummy loads and one commercial one, and the readings are repeatable. I have checked all three loads against my antenna analyzer, and all of them show 1.1 or less on all those bands, 6m having the largest SWR of 1.1.

Should I be concerned about operating on 6m, given the faulty indicator? Is there some testing I can do, such as removing the antenna tuner and repeating the test?

Thanks in advance.
