Sebastian,
Be careful - do not jump to conclusions.
The older XV144 crystals were pretty close to the correct frequency.
Then the manufacturer lost the design (I am not sure how that happened),
and began shipping crystals that were a bit higher in frequency. Since
things cannot go "backwards" to recover, the L19 addition was created to
compensate for the new crystals.
So bottom line, if you have an older XV144 and add L19, you will find
the Local Oscillator frequency will be significantly lower than 116
MHz. Yes, the addition of L19 to the older crystal will allow you to
pull it, but you will not be able to get the frequency high enough.
