[Elecraft] K2 assembly Bargraph question

[Don Wilhelm]

  Ross,

The steps in assembly part 2 should not have any direct effect on the 
bargraph, and at this point you should have a fully functioning receiver 
on 40 meters.

Go back over your work, particularly the soldering.  Read over the 
soldering tutorial that came with your K2.  If the solder connections do 
not look like the renderings for good solder connections, remove the 
excess solder and solder it properly.
  I recommend using a slightly higher iron temperature than that 
indicated in that document to be certain the solder pads are adequately 
heated.  Watch the solder as it is applied, it should flow out to an 
almost invisible edge on both the solder pad and the component lead.

Use the parts placement diagram in the back of the manual to check the 
orientation of the active components, particularly the diodes.

You might also try the applicable DC voltage measurements in the DC 
Voltage chart.

Good luck.
