Yes, David, I do have the crystal oven in the XV144 that I am currently 
using with the K2 as I am still awaiting delivery of my K3.  I only 
apply power to the XV144 when I intend to operate on 2 metres.  I do, 
however, apply power to it about 15 minutes before going on the air, 
otherwise there is noticeable drift while the oven warms up. I have JP9 
set to 4-5 as recommended in the manual (Rev. B) when the XV144 is 
fitted with the crystal oven.

I hope that helps.
