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).
