Good points, Ray and Jim, I should have been more detailed with what I
posted. I checked The Bird 43 with two other Bird 2500w slugs from
friends and they were all reading the same with a dummy load at 1500w.
I did the KPA1500 calibration using the Bird with a high power dummy
load, then checked again with my antennas in band segments where they
present no significant reflected power and near 1:1 SWR. At those
points they were in sync. Most of my antennas are flat on CW segments
at specific spots without using the tuner in the KPA1500. I operate 99%
CW and realize that when the load changes from 50 ohms the Bird reads
wildly high and cannot be trusted. - Jim W6YA
