I don't know if others have experienced this issue, but from previous postings on low power on 10m it's possible...

My K3/100 has the KAT3 auto ATU fitted, when I have the ATU in bypass and use the antenna 1 socket (as you are asked to when setting up the K3's power calibration), there is a residual SWR when on the 10m band. If I select antenna socket 2 there is no residual SWR. I've seen as high as a 1.7:1 SWR, which not surprisingly results in lower power on 10m unless I use the internal ATU.

Anyone else seen this?
