[Elecraft] K1 KAT1 SWR Adjustment

My new K1 is working great!

However, the SWR indications appear to be a bit low.

For example, I have a ground mounted vertical antenna (Hy-Gain 18-HT Hy-Tower) with lots of radials.  The SWR as indicated by the K1 is 1.0:1, which does not appear to be correct.  My trusty MFJ 249 tells me the SWR on this antenna is closer to 1.5:1, as I would expect.

If I connect a non-inductive dummy load of 100 or 25 ohms, the indicated SWR is closer to 1.5:1 instead of the expected 2.0:1.

When adjusting C9 for the lowest possible voltage, the instructions tell me to set the power out to 5.0 watts, however the manual does not tell me to increase power from the 1.5 watts nominal tuning output level to the full 5.0 watts.

Should I enter TUNE mode, then tap to increase output power to 5.0 watts as I make the C9 adjustment?
