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
Steve,
Set the menu ATU parameter to CAL P when adjusting R1 for the power
reading. CAL S is the setting used to align the SWR (use a dummy load
which will provide a known SWR such as a 25 ohm or 100 ohm load which
give a 2.0 SWR).
Also, be certain that your RF Probe is a type that
