Retuning the DMC DRO locked oscillator to use as LO in 24GHz

Now I’ m looking retune the DRO locked oscillator modules to 23616MHz to get a IF of 432Mhz at 24048MHz. To get 23616MHz I can use 98.4MHz (x240) and 105.42857MHz (x224). As I have a xtal of 105.43857Mhz I wish use the same in the two units, but have in one unit dosen’t works.
The unit that originally have a xtal of 99.04MHz dont accepts xtals more high than 100Mhz, and the units that originally have a xtal of 105.99MHz dont accepto xtals of less of 100Mhz. Comparing the units, looks that the issue is in the wire inductors located near of the xtal.

To check the reference inside of the unit exists a SMA located in the upper right that gives the ref freq x4. After modify the coils now and retuning the filter located in the bottom right , the unit that only accepts xtals up to 100MHz locked now can be used with the 105.43857MHz xtal.
