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.

73,
