Ed, I have seen a hex schmitt trigger inverter used for this.
The output of the OXCO goes into all 6 schmitt rigger inverter inputs and then on the output side you have the output leg of each inverter connected through 300 ohm resistance. Thusly you get 6 hex schmitt trigger inverters wired in parallel and with a combined output resistance of 50 ohms. Very simple and might be just the thing you're looking for.

It seems a shame to have that nice 10 MHz source without having access to it. I was thinking of adding a buffer amp and bringing out the 10 MHz signal. It shouldn't be too hard, but before I reinvent the wheel, has anyone done this and do you have any suggestions or advice?
