KXV3 question

I bought a used K3 and found that the lower right screw that holds the
KXV3t against the rear chassis had fallen out during shipping. I took it
apart and found the lock washer and nut. Figure 10 in the manual shows
that there should be a spacer attached to the KXV3. The space is there on
the top left mounting hole, but not the lower right one. There is no
evidence that it was ever one soldered to it. My concerns are

1) Is the space still somewhere in side the radio causing very bad things
when I power it up.

2) Without this spacer the KXV3 starts to flex if tightened to much an the
KXV3 may short against .the rear plate. If not tightened enough it will
vibrate loose again.

Can anyone confirm that this spacer should have been on both mounting
wholes ?

Here is a link to pics of each mounting hole.

Re: KXV3 question

There is clearly a spacer on each of the two screws. Figure 55 of the K3S manual shows the bottom screw and spacer on the KXV3B which is the same mechanically.

Mike,

Turn the K3 upside down and shake it a side to side, then turn it left
and do it again. turn it right and repeat to see if it will fall out.
Shaking it will not normally hurt anything - if anything shakes loose
(other than the spacer)

If you can't find the spacer, you may be able to slide some split
lockwashers between the board and the rear panel that fits over the
board. Removing the left side panel will make access easier.

The Assembly manual should provide enough info to answe your questions. The spacer should be referenced to the parts inventory in rear of manual and available via phone call to Elecraft. Ask for Madelyn.

Re: KXV3 question

The spacers are not mentioned as separate parts as far as I found. I don’t remember thinking about them even after building two kits. I believe they were fastened to and part of the board.
