Those pesky 14 crystals

[Steven Pituch]

Hi all,

This has got to be a stupid question, but hey, it happens sometimes.
Part of the reason is that I haven't had to open up the case of my K2 in
6 years and now I sort of forgot how the thing works.

Anyway, I am faithfully upgrading my K2 #402, and have gotten to the
part where it is suggested to shorten the ground leads to the 5 crystals
in the cohn filter.  I figure this is a good time to replace the
crystals since I bought the 14 crystal replacement pack.  However, I
counted nine 4.091 mHz crystals in the K2 and 7 crystals on the ssb
board.  This makes 16 crystals if my math is correct.

I assume x7 thru x11 are replaced, but don't know which two of the x3
thru x6 are replaced on the main board.  I also assume all 7 of the
crystals on the ssb board are replaced.

I fiqured this must all be explained somewhere, but haven't found it
yet.  Advice is appreciated.

Thanks,
Steve, W2MY

Hi Jim,

Are you sure about replacing X3 & X4 in a BFO mod kit?  The BFO temp
stability kit does not include replacing the crystals.  Perhaps I missed
one of the modes but I thought I ordered them all.  Or perhaps you
needed a special upgrade because your SN is low.

Wondering in Texas,
Steve
