K3 - Transmitter Gain Calibration Question

[Robert Dorchuck]

In going through the  Transmitter Gain calibration procedure for 5 and 50 watts

the actual power output measured on an external wattmeter (W1 & Powermaster)

drops off for the higher bands(4 and 40 watts on 10 meters) even though the

VFO B indicator remains at 5 watts and 50 watts.  Am I missing something or is

this normal?

Normal ... the internal wattmeter appears to have a slope.
On one K3, my power output is about 54W on 160,  50 W on 20,
47W on 10 and 42W on 6.  The other radio shows 52W on 160,
50W on 20, 47W on 10 and 46W on 6.

73,
