Raj,
The full set of oscillator and oven power jumper options is on page 74 of
the transverter manual. If you are using the oven and want the best
stability, I would believe you would want the oscillator and oven on all the
time (even when the K2 is off), and for that, the jumper is placed on 4 and
5. You are correct - if you want the oscillator and oven to be powered only
when the K2 is powered, the jumper goes on 2-3. With the junper on 1-2, the
oscillator and oven are powered only when the transverter is selected.
73,
