Ken,
If you have a recent XV432 (within the past 2 months), it is being
shipped with the High Accuracy crystal.
Look at the markings on the crystal that came with the XV432, and
compare it with the crystal shipped with the High Accuracy Kit - if it
is the same, you can put either crystal in and Check L19 as well, they
should be the same.
In other words, the High Accuracy Kit is a retrofit for older XV432
transverters, and is not necessary for new ones.

Hi folks,
I'm working on my XV432 kit this weekend. I ordered the high accuracy
crystal and the crystal oven options as well. I'm on page 31 of the
XV432 manual, where it is asking me to locate L4 and L19 for
installation. I see that L19 appears to get replaced when installing
the high accuracy crystal option.
The manual says:
L4 has an orange body with four turns. (It looks red to me and it has
3.5 turns, close enough I guess)
L19 has a yellow body with four turns. (I count 4.5 turns,
_definitely_ one more turn than L4. At least it's yellow)
The installation instructions that come with the high accuracy crystal
option say to remove L19 from the circuit board. Since I'm just about
to install it this seems like a good time to make the substitution.
EXCEPT, it says that L19 has a RED plastic coil form, not yellow like
the XV432 manual says. I do note that the substitute coil that comes
in the high accuracy crystal option is yellow and has exactly the same
4.5 turns as the yellow bodied coil called L19 in the XV432 assembly
manual.
I assume the error is in the instruction sheet for the high accuracy
crystal option, and that they meant to say that L19 is yellow and not
red. However, I'd feel safer if someone who has built one before
could kindly confirm this.
The second thing that bothers me is why does one 4-turn inductor have
one more turn than the other 4-turn inductor?
Any assistance will be gratefully accepted.
Thanks and 73,
Ken Alexander
