"Do you find a high degree of correlation between your (assumed) K3 and KAT500 SWR readings across various levels of SWR? "
I don't have a K3. I do have loads of recorded data that would allow comparison of KPA500 SWR and LP-100A SWR and a more limited set of data that would allow comparison of KAT500 SWR with LP-100A SWR. I have not performed either comparison but, as a general observation, it's obvious that the LP-100A is far more useful at low power levels or for mismatches that would give low reflected power. At high power levels there is quite good agreement between the LP-100A and the KPA500 for power and SWR. Since I know that, I look mainly at the LP-100A data. I did a quick test on 20 m. For an antenna system load that my LP-100A reports as SWR 1.09 with Z of 52.7 ohm at 4.3 deg it took about 70 W output power for my KAT500 to change from 1.00 to 1.11 SWR. To look at this another way - until the meter moves off the peg it isn't telling you much about the signal being measured. All it's telling you is that you need a better meter. I'm not saying there is anything wrong with the KPA500 or KAT500 SWR metering. You just need to know how it behaves and what it is useful for. I expect the same applies to the K3 SWR meter.
