Noticed today 20m output measured by LP100A was 90w when K3 wattmeter set to 100w. Same with 10m; other bands measured close enough. Updated firmware to latest and performed Transmit Calibration. Calib:WM HP at 50w set to agree with LP100A. In order to get 100w on LP100A, I have to crank the K3 output so that it reads 110 on the internal wattmeter. Why? Slope effect of internal WM?
ATU is in Bypass; tried two different dummy loads with same result. Yes, I know 10% difference is barely noticeable at the other end; it's annoying. What am I doing wrong?
