Hi all, I decided to realign my ole trusty KAT2. Adjusting the bridge null seemed to go OK. However, when I adjust the power knob to give 15.8 Volts (5 Watts) at my precision dummy load (50.3 Ohms), turning R1 clockwise to the maximum position only shows 4.4 Watts on the CAL S readout. Any suggestions? Thanks, Steve, W2MY
