William,
Thanks for that clarification. Connect the KPA100 to a good dummy load
and do the wattmeter alignment and calibration as indicated in the
KPA100 manual page 48 - see the SWR Bridge Null Adjustment and also the
Power Calibration sections.
You must do the bridge null before attempting the Power Calibration.

William,
Are you reading the K2 display correctly when you do a TUNE?
Normally the K2 displays the power on the left and the SWR on the right.
The power is normally 20 watts and the SWR will be shown as 2 digits
(1.0 through 9.9).
In other words, you will see something like "20 1.0".
If the KPA100 wattmeter is not indicating properly, it may be that diodes
D16 and D17 have become damaged, or it may just be that the wattmeter needs
to be balanced and calibrated.

Hi group,
Perhaps it's a silly question, but i don't understand something.
I have a K2 100 watt but I don't think any other set will make a
deferens.
the set is connected to a tuner (AT-100Pro LDG) and it tunes as far as
I can see ok.
But now what I notice, when I tune the tuner tunes to swr 1.1 so that
seems
to be ok, but my K2 gives me 2.0 1.
Does that mean my K2 sees a swr from2.0 whil my tuner says it is 1.0 ??
