Brian,
In later XV transverters, JP9 controls when the crystal oven is powered.
Since you do not have JP9, even if you have a crystal oven, it will
still work fine.
The oven will be powered when the XV50 is powered. Just allow some time
for it to warm up (about 20 minutes).
Actually, the 22MHz crystal does not drift much and usually does not
require the oven.
73 and Happy Thanksgiving,
Don W3FPR

Hello - I recently purchased an XV50 to use with my K2. While setting
it up for a K2 with no K60XV per the manual, I noticed that there is
no JP9, where I am supposed to short pins 1-2. On closer inspection,
my XV50 has a rev B board and it appears these pins don't exist. The
assembly manual I found online is for a Rev E board and owners manual
is for Rev F1.
I'm assuming all the other jumper settings from the Rev E manual are
correct for my Rev B XV50, but I thought I'd ask here for
clarification before I damage my XV50, since it's almost irreplaceable
now days. Also a Christmas wish would be to purchase a K60XV if anyone
has one laying around that they'd be willing to sell.
