[Elecraft] K2KSB2XTLS mod question

[Don Wilhelm]

Sam,

No "gotchas", but on the RF board, solder the grounding leads low on the 
crystals, and ground them on both sides.  On the KSB2, consider also 
grounding the crystals near the base.  That is possible if you mount the 
crystals one at a time - X4 first, then solder its ground wire - after 
that, X3 and X5 can be mounted and their ground wires soldered near the 
bottom.   Then you can install X1, X2, X6 and X7.  You then have only 2 
ground wires to work with, so bend one ground wire around the base of  
X2 and X1 and solder - do the same for the other ground wire and X6 and X7.

The result will be a slightly better OP1 filter.  If you did not follow 
the description above, that is OK, just solder to the top of the 
crystals.  There is a small improvement, but not enough to 'write home' 
about.

73,
