[Elecraft] backlight installation

Just completed the K-1 backlight mod; nice addition.  I had built the K-1 
with silver solder, so approached the mod job with fear and trepidation, 
based on comments on this list. Some of the LCD holes cleared OK using 
desoldering braid; others refused to clear. Tried a solder sucker without 
success. Finally, I heated the stubborn holes while gingerly inserting a 
stainless pin, then carefully removed the pin (solder doesn't stick to 
stainless pins). This pushed the solder out of the hole, creating a "peak" of 
solder sticking out of that side of the hole, which was then easily removed 
with braid.

Regarding the insulator card assembly, there was no "stickum" on the back 
side of the card (unlike the black rubber spacer in the original installation, 
which did have "stickum"), and the directions did not mention how the card 
was to adhere to the PCB, so I used some double-sided tape to fix it in 
place.

In spite of the hassle, I still like silver solder!
