[Elecraft] K2 BFO CW alignment question

[Mark Petrovic]

Don, the soldering on RP1 is very clean, top (viewed from the side of the
board with a light and magnifying glass) and bottom.  RP1 is aligned
correctly, and I've verified that it is the correct part for this location.

Worth mentioning is that the rubber spacer that installs onto the
bottom-side of the board in the corner nearest pin 10 of RP1 is attached
with a small drop of super glue (the original adhesive on the rubber pad
failed, as the pad fell off during casual handling of the board).  My
understanding is that this cyanoacrylate  super glue  is non-conductive,
nor does the spacer w/glue bridge any solder pads.  I've not inspected the
front panel board from the top, as this would require unsoldering the 4
leads holding the encoder board to the front panel board.
