K1 RF Board extra parts

[WA7CS]

Just finished inventory on a new K1.

All of the taped resistors matched the inventory list - however, I found
a 100K Ohm resistor that was not listed on the inventory page - it was
not taped with the others but was just loose in the bag.

What is this one for?

Yup - I'm pretty sure.  Turns out I've got a nasty case of
color-blindness - therefore I'm forced to measure each and every resistor.

It gets even worse - as a teenager I decided I wanted to become an
electronics genius, so as part of my college education electronics lab
was pure folly!

By the way, the genius part never really worked out.

Me too, so I trained a small daughter to read color codes. She was no
more than 4 years old, and she had her own place at my bench. I would
hand her a resistor and she would say "brown, black, yellow!" Now she's
about to turn 34 and lives 9000 miles away, so I'm back to the VOM.

It would be my guess that it is R19, associated with the front panel assembly.  R19 is a 100k-ohm resistor that was added *after* the first few hundred K1s to improve the linearity of the VFO tuning.  It will be soldered across two of the terminals of the VFO potentiometer, so it will not actually be installed on any of the K1's PC boards.

My K1 was one of the first (#175), so I don't know how K1 kits 2500 units later are being packaged.  I may be wrong.
