[Elecraft] K2 - grounding of RCVR filter Xtals

[Lynn Burlingame]

I turned the board on edge and inserted the ground leads through the
board from the back side.  I then clamped the end with a pair of
locking jeweler's tweezers and just let the tweezers hang down the
side of the board.  This made it easy to solder the lead.  I then
trimmed the lead and used a dental pick to form it appropriately along
the side of the crystal.
