[Elecraft] KDSP2 2x10 20 pin header

[Trevor Day]

Hi John,
My method was to use a craft knife initially to ease up the plastic 
shroud from the PCB.  Then you can get a flat blade screwdriver in to 
lever the shroud up and away from the board.  This leave all 20 bare 
pins.  The fault is not obvious at first glance;  if you imagine each 
pin as an elongated 'Y' shape, the two points at the top of the 'Y' have 
been bent too close together preventing the male half of the plug from 
fitting.   A small screwdriver carefully used can pry apart each half of 
the pin.
The plastic shroud can then be replaced by carefully pressing it back 
into position.

This worked for me, but if all else fails, at least it makes it easy to 
remove the pins individually to allow a replacement to be fitted.

gl,
Trev G3ZYY
