How about a 10 MHz OCXO and a divide by two chip? Maybe an op-amp to

Yes I've thought about that. In fact it might be the better way to go as
10MHz output would definitely be more useful.
I need to trace out the circuit to see what happens to the 5MHz signal
on its way to the rear BNC and also on its way to the logic circuits to
see if I could get a divider in there at the right point to send 5MHz to
the logic and 10MHz on the rear BNC.
As you suggest the easiest is if I can find a unit with a similar
control voltage range (0.5 to 7V and approx +/- 1 in 10^7 adjustment).
