[Elecraft] K1- KAT1 SWR Bridge Adjustment--no voltage variation.

[Rich NU6T]

I'm in the final stages of testing/adjusting a newly built KAT1 board in 
a 2-band K1 (RF Board rev E).  In the SWR Bridge adjustment task, I'm 
not seeing any voltage change beyond what seems to be random noise.  I'm 
using a plastic adjustment tool and a DMM.

I'm concerned I may have installed trimmer C9 backwards.  It has a 
broad/wide side and a blunted narrower side.  Instructions call for the 
flat side to the left.  The broad side seems curved, so I placed the 
narrow side to the left, wide side to the right.

Instructions indicated to follow the pattern on the board for C9 
installation, but my board has two holes and what look like horizontal 
parentheses with no indication of broad, flat or narrow sides.

The manual notes that the null may be sharp.  I'm not seeing it.

Thanks for any advice.
