[Elecraft] KPA-500 watt meter vs. Palstar

[k2zf50 at aol.com]

Hi,



My KPA-500 watt meter and my Palstar watt meter read about the same at the higher power readings. But at the 100 watt and lower ranges there is a significant difference. My question is which is the more correct reading at the lower ranges, the Elecraft or Palstar. If I want to calibrate my K3 which one would be more accurate? Being that the Elecraft is a digital display would that one be more accurate?


Thanks,
