[Elecraft] KAT2 C55 nul adjustment

[Mike Weir]

I have completed the KAT2 tuner and adjusted C55 but could only get it down to between 010 - 009. I did notice that when I got a reading to 010 any further adjustment would result in a large jump. I would then have to take time and fine adjust C55 to 010 and maybe hit 009. I continued on with the rest of the tests and adjustments and the tuner seems to work fine. The only thing I did noticed was when checking out the SWR on all bands on some bands I got as high as 1:5. But I did read that all bands may not read 1:1 SWR. So my question is should I had been able to adjust C55 lower than between 010 and 009? Also is the SWR rise on some bands related to this or as it says in the manual that this my happen and is just fine?MikeVE3WDM
