Interesting! I just ran some tests on my station into Bird load; tuner bypassed:
At 50.1 mHz:
LP-700 1.06
K3 1.5
KPA1500 1.0
At 9.56 mHz (geometric mean freq)
LP-700 1.05
K3 1.1
KPA1500 1.0
At 1.825 mHz:
LP-700 1.05
K3 1.1
KPA1500 1.0
My KPA1500 looks good but K3 is off on 6m.

A few months ago I wrote about the potential errors in measuring SWR with
amateur grade equipment. See my comments in this thread:

I imagine "the best they can do" is accurate.

ps. I also said that if I was wrong, I was sure I would hear about it.

I also note that when into a perfect 50 Ohms, and the tuner bypassed, on 6
meters, my KPA1500 says the SWR is 1.4:1. On 10 meters it reads 1.2:1. Rene
from Elecraft says "this is the best they can do".
Other than the issues above I am very happy with the KPA1500.
