[Elecraft] [Remedy] K2 #1059 VCO Alignment to 6.0V

[wo7t@juno.com]

Hi All:

Just wanted to document the resolution to what's been my only
issue to date on my K2 build up.

I guess on some of the earlier K2's I missed recommendations
to drop back to 15 primary windings on T5 vs. the manual instruction
to 16. Once I did this, I had variablity with L30, and could hit 
the 6.0V level.

Many thanks to Carl Morris, who led me down this path. I was somehow
believing at the higher voltage I would still see variability with 
tuning L30. Not so. If starting voltage here is too high, take off 
a primary turn.
