Are you talking about locking the 50MHz VCXO to my 10 MH. Standard? I want the 25MHz to be from my 10MHz OCXO which is my station standard which will locked to GPS eventually.

A better and easier way is to phase lock a crystal oscillator.
I would use a 50 MHz VCXO and divide the output by 2 to get a
25 MHz square wave.
