Previous/spare timing master

The previous timing master which was again running out of range on the voltage to the OCXO, see alog 61988, has been retuned using the mechanical adjustment of the OCXO.

Today's readback voltage is at +3.05V. We will keep it running over the next few months to see, if it eventually settles.
