It is probably necessary to restate my question with more precision. 1. I have calibrated the K3s using Elecraft K3 Utility
2. I have carefully calibrated the W1 using the DDM method with a good quality DDM. 3. Comparing the results, I see that the W1 consistently calculates power about 1 dB higher than the K3s. Statistically, I would have expected them to be closer. From the W1 specifications, and not knowing the K3s power accuracy specifications, it seems that, possibly, the K3s is displaying about 3 sigma low and the W1 3 sigma high, which is unlikely. 4. The question: Should the K3s be calibrated from the W1 or should the W1 be calibrated from the K3s? (There could be a detailed, separate discussion of the meaning of "average" power and "PEP" as used in the W1 programming reference. It is my belief that the two should be the same thing if using a cw signal and the FCC definition of "PEP". It would be interesting to know what is going on in the K3s transmitter gain calibration process. It seems like there is an internal power measurement process and the gain is being set against that. Does that internal measurement process have accuracy equivalent to the W1 or vice versa?)
