What happens if you adjust L7?

I haven't touched it. But as far as I understand its there to avoid
oscillation
to disturb regulation process insuide L09. So it should have nothing to do
with the crystal "pushing". (Let me know if I am totally wrong...

Pasi, oh2pt

It looks like a fairly low inductance which resonates with
the 12pf, 68pf and other capacitances in the oscillator to form
a 116MHz tuned circuit. Try adjusting it to see if it will
pull the oscillator to the correct frequency. If you turn
it too far, it will reduce the L.O. output or stop it
from running. If you are not happy with the result, you
can always put it back where it was.

If all else fails, you could try putting a variable capacitor
or inductor in series with the crystal.
