[Elecraft] K2 12m alignment

[Robert Kasten]

Finished my K2 in the last few days and really enjoyed the build. It was
just like old times.

All bands except 12m have aligned OK...but I cannot get any more than .5W
output on 12m - no matter the C44/46 trimmer cap settings or the power
setting. And while it not fun, I pulled components C42,C43,C44,C45,C46,C47
and C48 and they all showed fine on the cap tester. C32 and C34 are
adjustable from about 35pf to 70pf.

I measured RF voltages. All transmit stages were fine up until the bandpass
filter. Zero RF volts at W6 and the anode side of D1. One thing I have seen
on keydown is the RF on both sides of C48 jumping to about .4V RF, then
right back to 0. Cap C42, on the other hand shows well over 1V RF on
keydown.

Because 10m is aligning/peaking totally fine and putting out 14W, and the
caps and inductors test good, at this point should I assume K7 isn't
swithing? I am not really sure of the best way to test K7 in place. Any
tips would be most appreciated. :-)
